Clean the product

Clean the exterior

Use a soft, damp, lint-free cloth to wipe dust, smudges, and stains off of the exterior of the product.

Clean the flatbed scanner glass

Dirty glass, from fingerprints, smudges, hair, and so on, slows down performance and affects the accuracy of special features such as fit-to-page and copy.

NOTE:

If streaks or other defects appear only on copies produced from the ADF, clean the ADF scanner glass (step 3). It is not necessary to clean the flatbed scanner glass.

1.

Turn off the product, unplug the power cord from the electrical outlet, and raise the scanner cover.

2.

Clean the glass by using a soft cloth or sponge that has been moistened with nonabrasive glass cleaner.

CAUTION:

Do not use abrasives, acetone, benzene, ammonia, ethyl alcohol, or carbon tetrachloride on any part of the product; these can damage the product. Do not place liquids directly on the glass. They might seep under it and damage the product.

3.

Clean the ADF scanner glass by using a soft cloth or sponge that has been moistened with nonabrasive glass cleaner.



Clean the scanner-cover backing

1.

Turn off the product, unplug the power cord from the electrical outlet, and raise the scanner cover.

2.

Clean the white scanner-cover backing by using a soft cloth or sponge that has been moistened with mild soap and warm water. Also, clean the ADF scanner glass (callout 1) next to the flatbed scanner glass.

3.

Wash the backing gently to loosen debris; do not scrub the backing.

4.

Dry the backing by using a chamois or soft cloth.

CAUTION:

Do not use paper-based wipes because they might scratch the backing.

5.

If this does not clean the backing well enough, repeat the previous steps and use isopropyl alcohol to dampen the cloth or sponge, and then wipe the backing thoroughly with a damp cloth to remove any residual alcohol.

Device information

The HP ToolboxFX Device information page stores data about the product for future reference. The information that you type in these fields appears on the Configuration page. You can type any character in each of these fields.

NOTE:




Paper handling

Use the HP ToolboxFX paper-handling options to configure the default settings. These are the same options that are available on the product control-panel.

Three options are available for handling print jobs when the product is out of media:

● Select Wait for paper to be loaded.

●

Select Cancel from the Paper out action drop-down list to cancel the print job.

● Select Override from the Paper out time drop-down list to send the print job to another paper tray.

The Paper out time field specifies how long the product waits before acting on the selections. You can specify from 0 to 3600 seconds.

NOTE:


Print quality

Use the HP ToolboxFX print-quality options to improve the appearance of print jobs. These are the same options that are available on the product control panel.

The four options provided for controlling print quality are resolution, REt (Resolution Enhancement technology), print density, and EconoMode.

●

Resolution. Select 600 resolution for average print jobs and Fast Res 1200 for higher-quality print jobs.

●

REt. You can turn on REt, which HP provides for improved print quality.

●

Print density. For increased print density, select a higher number. For decreased print density, select a lower number.

●

EconoMode. Turn EconoMode on when you are printing average print jobs. EconoMode is a feature that allows the product to use less toner per page. Selecting this option might extend the life of the toner supply and might reduce cost per page. However, it will also reduce print quality.

The printed image is lighter, but it is adequate for printing drafts or proofs. HP does not recommend full-time use of EconoMode. If EconoMode is used full-time, it is possible that the toner supply will outlast the mechanical parts in the print cartridge. If print quality begins to degrade under these circumstances, you will need to install a new print cartridge, even if there is toner supply remaining in the cartridge.

NOTE:


Paper types

Use the HP ToolboxFX Paper types options to configure print modes that correspond to the various media types. Select Restore Modes to reset all modes to the factory settings.

NOTE:




System setup

Use the HP ToolboxFX system settings options to configure global settings for copy, fax, scan, and print, such as jam recovery and auto-continue.

NOTE:

Embedded Web server

This product is equipped with an embedded Web server (EWS), which provides access to information about product and network activities. A Web server provides an environment in which web programs may run, much in the same way that an operating system, such as Windows, provides an environment for programs to run on a computer. The output from these programs can then be displayed by a Web browser, such as Microsoft Internet Explorer, Safari, or Netscape Navigator.

An “embedded” Web server resides on a hardware device (such as an HP LaserJet product) or in firmware, rather than as software that is loaded on a network server.

The advantage of an EWS is that it provides an interface to the product that anyone with a networkconnected product and computer can use. There is no special software to install or configure, but you must have a supported Web browser on the computer. To gain access to the EWS, type the IP address for the product in the address line of the browser. (To find the IP address, print a configuration page.

For more information about printing a configuration page, see Information pages on page 36 .)

NOTE:

For Macintosh operating systems, you can use the EWS over a USB connection after installing the Macintosh software included with the product.

Features

The EWS allows you to view product and network status and manage printing functions from a computer.

With the EWS, you can complete the following tasks:

●

View product status information

● Determine the remaining life on all supplies and order new ones

●

View and change part of the product configuration

● View and print some internal pages

●

Select the language in which to display the EWS pages

● View and change network configuration

●

Set, change, or clear the product security password.



NOTE:

Changing network settings in the EWS might disable some of product software or features.

Scanner and ADF functions and operation

The following sections describe how the document scanner and the automatic document feeder (ADF) function.

Scanner functions

The scanner uses a light source, a color-separation method, and a charge-coupled device array (CCD) to collect optical information about the document and transform that into an image file. The scanner consists of these elements:

● A lamp (LED)

●

Five mirrors and a lens

●

A CCD

Figure 4-2

Optical system

Scanner Glass

LED Lam p

CCD

Lens

The scanner lamp illuminates a small strip of the document (called the raster line). The mirrors direct the light through the lens to the CCD. The CCD senses and records the light, creating an analog representation of the raster line. If the ADF is being used, the document then advances in the ADF to the next raster line. If the flatbed is being used, the scanner module advances to the next raster line.

This advancing and collection process continues to the end of the sheet.

The image data is collected in the motor controller board, where it is processed and sent to the formatter.

The formatter then handles the image data, outputting it as a copy, sending it through the fax card as a fax, or directing it to the computer as scanner output.

The resolution of the image data collected depends on the task being performed. Each pixel has 8 bits for each of the three colors (256 gray scale levels for each color), or a total of 24 bits per pixel (24-bit color).



Scanner operation

At power-on and periodically at other times, the scanner assembly moves systematically to locate its home position. It then calibrates to a white strip located under the glass at the right end of the scan tub.

If the product detects a document in the ADF when a copy or scan is initiated (from the software or the control panel), the scan module moves to the left side of the scan tub and stops. The image is acquired as the paper is fed through the ADF past the scanner module.

If no document is detected in the ADF, the scan module acquires the image from the flatbed glass while slowly moving within the scan tub.

ADF operation

Standby (paper-loading) mode: In standby mode, the pickup roller is up and the stack-stop is down, preventing the user from inserting the original document too far. When a document is inserted correctly, the paper-present sensor detects its presence.

The standard operation of the ADF consists of the pick, feed, and lift steps.

Pick: When it receives a copy or scan command, the ADF motor engages the gear train to lower the pickup-roller assembly and raise the stack-stop. The first roller, called the pre-pick roller, moves the top few sheets forward into the ADF. The next roller is the pickup roller. This roller contacts the ADF separation pad, which separates multiple pages into single sheets.

Feed: The single sheet continues through the path. Along the way, the form sensor, which is a set distance from the ADF glass, detects the sheet. This alerts the scanner to start when the page reaches the glass. The scanner acquires the image, one raster line at a time, until it detects the end of the page.

The page is then ejected. The pick and feed steps are repeated as long as paper is detected in the ADF input tray.

Lift: When no more paper is detected in the ADF input tray and the form sensor detects the trailing edge of the last page, the last sheet is ejected and the motor turns in a sequence that lifts the pick-roller assembly to standby (paper-loading) mode again.

The ADF will not function when the ADF cover is open. The paper path is incomplete if the ADF cover is lifted from the glass.

The paper-present sensor determines if paper is in the ADF. The form sensor detects the top and bottom edges of the document. One other sensor detects an open ADF door.



ADF jam detection

The ADF has two sensors that detect paper. The paper-present sensor detects the presence of media in the ADF input tray. The form sensor detects media moving through the ADF. If a jam is detected, the

ADF immediately stops the paper feeding and a jam message appears on the control-panel display.

A jam can be detected under any of the following conditions:

●

Document-feeder jam. When documents are detected in the ADF input tray, and a command to copy, scan or fax is received, the scan module travels to the left side of the scan assembly and stops beneath the ADF scanner glass. The ADF then attempts three times, or for about ten seconds, to advance the paper to the form sensor. If the paper does not advance, the scan module travels back to the home position on the right side of the scanner assembly. The message

Document feeder mispick. Reload. appears on the control-panel display.

●

Long-document jam. If the paper has advanced to trigger the form sensor, but the trailing edge is not detected within the time allowed for a 381-mm (15-inch) document (the maximum allowable page length for the ADF), the scanner returns to the home position on the right side of the scanner assembly. The message Doc feeder jam. Clear, Reload. appears on the control-panel display.

●

Stall jam. When a page that is less than 381 mm (15 inches) long has advanced to the form sensor but has not left it within the expected time, the paper has probably stalled or jammed. The scanner returns to the home position on the right side of the scanner assembly. The message Doc feeder

jam. Clear, Reload. appears on the control-panel display.

●

Other. If the paper stops in the ADF and the scan module remains under the ADF scanner glass, an internal firmware error has probably occurred. This is usually remedied by cycling the power.

The pickup/feed/delivery system consists of several types of feed rollers and sensors. A motor and solenoid are used to drive the rollers. Three media-detection sensors detect media as it passes through the printer. If media does not reach or pass each sensor within a specified time period, the formatter determines that a jam has occurred.

The following components are identified in

Image-formation system

Laser printing requires the interaction of several technologies, including electronics, optics, and electrophotographics, to produce a printed page. Each process functions independently and must be coordinated with the other product processes. Image formation consists of the following five processes:

●

Electrostatic latent-image formation

●

Developing

●

Transfer

●

Fusing

●

Drum cleaning

These five processes contain seven steps, which are shown in

Figure 4-9 Image-formation system on page 59 and described in the following sections.

Figure 4-9


Step 1: Primary charging

DC and AC biases are applied to the primary charging roller, which transfers a uniform negative potential to the photosensitive drum.

Figure 4-10

Primary charging

ENWW Image-formation system 59


Step 2: Laser beam exposure

The laser beam scans the photosensitive drum to neutralize negative charges on parts of the drum. An electrostatic latent image is formed on the drum where negative charges were neutralized.

Step 3: Developing

The developing cylinder comes in contact with the photosensitive drum to deposit toner onto the electrostatic latent image.

NOTE:

The charges on the exposed area of the drum are shown as positive in Figure 4-11 Developing on page 60 . The charges are actually negative, but they are more positive than the charges on the

developing cylinder.

Figure 4-11

Developing

Toner acquires a negative charge through friction from the developing cylinder and the blade. When the negatively charged toner comes in contact with the drum, the toner adheres to the electrostatic latent image. The image on the drum becomes visible because of the toner.

Step 4: Transfer

The transfer charging roller, to which a DC positive bias is applied, imparts a positive charge on the print media. When the print media comes in contact with the photosensitive drum, the toner is transferred to the print media.



Figure 4-12

Transfer

Step 5: Separation

The elasticity of the print media causes its separation from the photosensitive drum. A static-charge eliminator aids separation by weakening any electrostatic adhesion.

Figure 4-13

Separation

Step 6: Fusing

The DC negative bias applied to the fusing film strengthens the holding force of the toner on the print media and prevents the toner from scattering.

Figure 4-14

Fusing

ENWW Image-formation system 61


Step 7: Drum cleaning

The cleaning blade scrapes the residual toner off of the photosensitive drum and deposits it into the waste-toner case.

Fax functions and operation (fax models only)

The following sections describe the product fax capabilities.

Computer and network security features

The product can send and receive fax data over telephone lines that conform to public switch telephone network (PSTN) standards. The secure fax protocols make it impossible for computer viruses to be transferred from the telephone line to a computer or network.

The following product features prevent virus transmission:

●

No direct connection exists between the fax line and any devices that are connected to the USB or Ethernet ports.

●

The internal firmware cannot be modified through the fax connection.

●

All fax communications go through the fax subsystem, which does not use Internet data-exchange protocols.

PSTN operation

The PSTN operates through a central office (CO) that generates a constant voltage on the TIP and

RING wires (48 V, usually). A device goes on-hook by connecting impedance (such as 600 ohms for the U.S.) across the TIP and RING so that a line current can flow. The CO can detect this current and can send impulses like dial tones. The product generates more signaling tones, such as dialing digits, to tell the CO how to connect the call. The product can also detect tones, such as a busy tone from the

CO, that tell it how to behave.

When the call is finally connected, the CO behaves like a piece of wire connecting the sender and receiver. This is the period during which all of the fax signaling and data transfer occurs. When a call is completed, the circuit opens again and the line-current flow ceases, removing the CO connection from both the sender and the receiver.

On most phone systems, the TIP and RING wires appear on pins 3 and 4 of the RJ-11 modular jack

(the one on the fax card). These two wires do not have to be polarized because all the equipment works with either TIP or RING on pin 3 and the other wire on pin 4. This means that cables of either polarity can interconnect and will still work.

These basic functions of PSTN operation are assumed in the design of the fax subsystem. The product generates and detects the signaling tones, currents, and data signals that are required to transmit and receive faxes on the PSTN.

Receive faxes when you hear fax tones

In general, incoming faxes to the product are automatically received. However, if other devices are connected to the same phone line, the product might not be set to answer automatically.

If the product is connected to a phone line that receives both fax and phone calls, and you hear fax tones when you answer the extension phone, receive the fax in one of two ways:

●

If you are near the product, press Start Fax on the control panel.

●

Press 1-2-3 in sequence on the extension phone keypad, listen for fax transmission sounds, and then hang up.

ENWW Fax functions and operation (fax models only) 63


NOTE:

In order for the 1-2-3 sequence to work, the extension phone setting must be set to On in the

Fax setup menu.

Distinctive ring function

Distinctive ring is a service that a telephone company provides. The distinctive ring service allows three phone numbers to be assigned to one phone line. Each phone number has a distinctive ring. The first phone number has a single ring, the second phone number has a double ring, and the third phone number has a triple ring.

NOTE:

The product has not been tested with all of the distinctive-ring services that telephone companies provide in all countries/regions. HP does not guarantee that the distinctive-ring function will operate correctly in all countries/regions. Contact the local phone service provider for assistance.

Set up the distinctive ring function

Press OK to save the setting.

Fax by using Voice over IP services

Voice over IP (VoIP) services provide normal telephone service, including long distance service through a broadband Internet connection. These services use packets to break up the voice signal on a telephone line and transmit it digitally to the receiver, where the packets are reassembled. The VoIP services are often not compatible with fax machines. The VoIP provider must state the service supports fax over IP services.

Because the installation process varies, the VoIP service provider will have to assist in installing the product fax component.

Although a fax might work on a VoIP network, it can fail when the following events occur:

● Internet traffic becomes heavy and packets are lost.

●

Latency (the time it takes for a packet to travel from its point of origin to its point of destination) becomes excessive.



If you experience problems using the fax feature on a VoIP network, ensure that all of the product cables and settings are correct. Configuring the Fax Speed setting to Medium(V.17) or Slow(V.29) can also improve your ability to send a fax over a VoIP network.

If you continue to have problems faxing, contact your VoIP provider.

The fax subsystem

The formatter, fax card, firmware, and software all contribute to the fax functionality. The designs of the formatter and fax card, along with parameters in the firmware, determine the majority of the regulatory requirements for telephony on the product.

The fax subsystem is designed to support V.34 fax transmission, lower speeds (such as V.17 fax), and older fax machines.

Fax card in the fax subsystem

Two versions of the fax card are used in the HP LaserJet M1522 MFP. One is used in the North

American, South American, and Asian countries/regions. The other is used primarily in European countries/regions.

The fax card contains the modem chipset (DSP and CODEC) that controls the basic fax functions of tone generation and detection, along with channel control for fax transmissions. The CODEC and its associated circuitry act as the third-generation silicon DAA to achieve compliance world-wide regulatory requirements.

European products must use the fax cord that is included in the product box. North American and Asian products should be compatable with any phone cord, although users who experience fax errors should try the included fax cord.

Safety isolation

The most important function of the fax card is the safety isolation between the high-voltage, transientprone environment of the telephone network (TNV [telephone network voltage]) and the low-voltage analog and digital circuitry of the formatter (SELV [secondary extra-low voltage]). This safety isolation provides both customer safety and product reliability in the telecom environment.

Any signals that cross the isolation barrier do so magnetically. The breakdown voltage rating of barriercritical components is greater than 5 kV.

Safety-protection circuitry

In addition to the safety barrier, the fax card protects against over-voltage and over-current events.

Telephone over-voltage events can be either differential mode or common mode. The event can be transient in nature (a lightning-induced surge or ESD) or continuous (a power line crossed with a phone line). The fax card protection circuitry provides margin against combinations of over-voltage and overcurrent events.

Common mode protection is provided by the selection of high-voltage-barrier critical components

(transformer and relay). The safety barrier of the fax card PCB traces and the clearance between the fax card and surrounding components also contribute to common mode protection.

A voltage suppressor (a crowbar-type SIDACTOR) provides differential protection. This device becomes low impedance at approximately 300 V differential, and crowbars to a low voltage. A series thermal switch works in conjunction with the crowbar for continuous telephone line events, such as crossed power lines.



All communications cross the isolation barrier magnetically. The breakdown voltage rating of barriercritical components is greater than 5 kV.

Data path

TIP and RING are the two-wire paths for all signals from the telephone network. All signaling and data information comes across them, including fax tones and fax data.

The telephone network uses DC current to determine the hook state of the telephone, so line current must be present during a call. The silicon DAA provides a DC holding circuit to keep the line current constant during a fax call.

The silicon DAA converts the analog signal to a digital signal for DSP processing, and also converts the digital signal to an analog signal for transmitting data through a telephone line.

The magnetically coupled signals that cross the isolation barrier go either through a transformer or a relay.

The DSP in the fax card communicates with the ASIC in the formatter using the high-speed serial interface.

Hook state

Another magnetically coupled signal is the control signal that disconnects the downstream telephone devices (such as a phone or answering machine). A control signal originating on the DSP can change the relay state, causing the auxiliary jack (downstream jack) to be disconnected from the telephone circuit.

The product takes control of calls that it recognizes as fax calls. If the product does not directly pick up the call, it monitors incoming calls for the fax tone or for the user to direct it to receive a fax. This idle mode is also called eavesdropping. This mode is active when the product is on-hook but current exists in the downstream phone line because another device is off-hook. During eavesdropping, the receive circuit is enabled but has a different gain from the current that is generated during normal fax transmissions.

The product does not take control of the line unless it detects a fax tone or the user causes it to connect manually. This feature allows the user to make voice calls from a phone that is connected to the product without being cut off if a fax is not being received.

Downstream device detection

The line voltage monitoring module of the silicon DAA can detect the line state as well as the downstream device. It tells DSP via DIB that an active device (telephone, modem, or answering machine) is connected to the auxiliary port on the product (the right side of the RJ-11 jack). The DSP uses the signal to ensure that the product does not go off-hook (and disconnect a downstream call) until it has been authorized to do so (by a manual fax start or the detection of the appropriate tones).

Hook switch control

In the silicon DAA, the CODEC controls the hook switch directly. The CODEC is activated when it receives commands from the DSP. When the circuit is drawing DC current from the central office, it is considered off-hook. When no DC current flows, the state is considered on-hook.



Ring detect

Ring detect is performed by the line voltage monitoring module of the silicon DAA, and is a combination of voltage levels and cadence (time on and time off). Both must be present to detect a valid ring. The

CODEC works with DSP as well as the firmware to determine if an incoming signal is an answerable ring.

Line current control

The DC current from the CO needs to have a path to flow from TIP to RING. The DC impedance emulation line modulator and DC terminations modules in the silicon DAA act as a DC holding circuit, and works with the firmware to achieve the voltage-current characteristic between TIP and RING. The impedance (the current-voltage characteristic) changes corresponding to certain special events, such as pulse dialing or when the product goes on-hook.

Billing- (metering-) tone filters

Switzerland and Germany provide high-frequency AC signals on the phone line in order to bill customers.

A filter in a special fax cable (for certain countries/regions), can filter these signals. Because these billings signals are not used in the U.S., these filters are not present in the U.S. fax cable.

To obtain a special fax cable, contact your local telephone service provider.

Fax page storage in flash memory

Fax pages are the electronic images of the document page. They can be created in any of three ways: scanned to be sent to another fax machine, generated to be sent by the computer, or received from a fax machine to be printed.

The product stores all fax pages in flash memory automatically. After these pages are written into flash memory, they are stored until the pages are sent to another fax machine, printed on the product, transmitted to the computer, or erased by the user.

These pages are stored in flash memory, which is the nonvolatile memory that can be repeatedly read from, written to, and erased. The product has 4 MB of flash memory available for fax storage; only a very small amount (several kilobytes) of it is used for the file system and reclamation. Adding RAM does not affect the fax page storage because the product does not use RAM for storing fax pages.

Stored fax pages

The user can reprint stored fax receive pages in case of errors. For a fax send, the product will re-send the fax in case of errors. The product will re-send stored fax pages after a busy signal, comm error, no answer, or power failure. Other fax devices store fax pages in either normal RAM or short-term RAM.

Normal RAM immediately loses its data when power is lost, while short-term RAM loses its data about

60 minutes after power failure. Flash memory maintains its data for years without any applied power.

Advantages of flash memory storage

Fax pages that are stored in flash memory are persistent. They are not lost as a result of a power failure, no matter how long the power is off. Users can reprint faxes in case the print cartridge runs out of toner or the product experiences other errors while printing faxes.

The product also has scan-ahead functionality that makes use of flash memory. Scan-ahead automatically scans pages into flash memory before a fax job is sent. This allows the sender to pick up


For more information on the HP LaserJet M1522 visit us at www.PrinterSupplies.com or call 800-551-1943 the original document immediately after it is scanned, eliminating the need to wait until the fax is transmission is complete.

Because fax pages are stored in flash memory rather than RAM, more RAM is available to handle larger and more complicated copy and print jobs.

Introduction

This chapter documents the removal and replacement of field-replaceable parts (FRUs) only. Replacing

FRUs is generally the reverse of removal. Occasionally, notes and tips are included to provide directions for difficult or critical replacement procedures.

HP does not support the repairing of individual subassemblies or troubleshooting at the component level.

Note the length, diameter, color, type, and location of each screw. Be sure to return each screw to its original location during reassembly.

Incorrectly routed or loose wire harnesses can interfere with other internal components and can become damaged or broken. Frayed or pinched harness wires can be difficult to locate. When replacing wire harnesses, always use the provided wire loops, lance points, or wire-harness guides.

Removal and replacement warnings, cautions, notes and tips

WARNING!

Turn the product off, wait 5 seconds, and then remove the power cord before attempting to service the product. If this warning is not followed, severe injury can result, as well as damage to the product. The power must be on for certain functional checks during problem solving. However, the power supply should be disconnected during parts removal.

Identify and correct print defects

Use the checklist and print-quality issues charts in this section to solve print-quality problems.

Print-quality checklist

General print-quality problems can be solved by using the following checklist:

1.

Make sure that the paper or print media that you are using meets specifications. Generally, smoother paper provides better results.

2.

If you are using a special print media such as labels, transparencies, glossy paper, or letterhead, ensure that you have printed by type.

3.

Print a configuration page and supplies status page at the product control panel.

◦

Check the supplies status page to see if any supplies are low or empty. No information is provided for non-HP print cartridges.

4.

Print a Demo page from the HP ToolboxFX. If the page prints, the problem is with the printer driver.

Try printing from another printer driver. For example, if you are using the PCL 6 printer driver, print from the PS printer driver.

◦

Use the Add Printer Wizard in the Printers (or Printers and Faxes in Windows XP) dialog box to install the PS driver.

5.

Try printing from a different program. If the page prints correctly, the problem is with the program from which you were printing.

6.

Restart the computer and the product and try printing again. If the problem is not resolved, see

General print-quality issues on page 158 .

General print-quality issues

The following examples depict letter-size paper that has passed through the product short-edge-first.

HP specifications.

If a repetitive mark occurs at the same spot on the page, install a new HP print cartridge. See


Use a different paper, such as highquality paper that is intended for laser printers.

If characters are incorrectly formed so that they produce a wavy effect, the laser scanner might need replacing.

Verify that the problem also occurs on the configuration page. If so, replace the laser/scanner. See

Laser/scanner assembly on page 121

.

The printed page is curled or wavy.

Text or graphics are skewed on the printed page.


In the printer driver, make sure the appropriate media type is selected.

If the problem persists, select a media type that uses a lower fuser temperature, such as transparencies or light media.

The media might have been in the input tray too long.

Turn over the stack of media in the tray.

Also, try rotating the media 180° in the input tray.


HP specifications.


Both high temperature and humidity can cause paper curl.

Check the product environment.

The media might be loaded incorrectly or the input tray might be too full.

Verify that the media is loaded correctly and that the media guides are not too tight or too loose against the stack.


HP specifications.




Problem

The printed page contains wrinkles or creases.

Toner appears around the printed characters.

Cause Solution

The media might be loaded incorrectly or the input tray might be too full.

Turn over the stack of paper in the input tray, or try rotating the paper 180° in the input tray.


HP specifications.

Verify that the media is loaded correctly and that the media guides are not too tight or too loose against the stack.


Air pockets inside envelopes can cause them to wrinkle.

Remove the envelope, flatten it, and try printing again.

The media might be loaded incorrectly.

Turn over the stack of paper in the tray.

If large amounts of toner have scattered around the characters, the paper might have high resistivity.


An image that appears at the top of the page (in solid black) repeats farther down the page (in a gray field).

Droplets of water are deposited on the trailing edge of the page.

Software settings might affect image printing.

In your software program, change the tone (darkness) of the field in which the repeated image appears.

In your software program, rotate the whole page 180° to print the lighter image first.

The order of images printed might affect printing.

Change the order in which the images are printed. For example, have the lighter image at the top of the page, and the darker image farther down the page.

A power surge might have affected the product.

If the defect occurs later in a print job, turn the product off for 10 minutes, and then turn on the product to restart the print job.

Moisture in the product is condensing on the fuser assembly. In excessively hot and humid areas, media retains moisture.

Try moving the product to a less humid area. Try a different media.

NOTE:

Water droplets do not damage the product.



Scan problems

Solve scanned-image problems

Problem

The scanned image is of poor quality.

Cause Solution

The original might be a secondgeneration photo or picture.

● To eliminate the patterns, try reducing the size of the image after scanning.

● Print the scanned image to see if the quality is better.

●

Verify that your resolution and color settings are correct for the type of scan job that you are performing.

●

For best results, use the flatbed scanner for scanning rather than the automatic document feeder

(ADF).

The image that appears on the screen might not be an accurate representation of the quality of the scan.

●

Try adjusting your computer monitor settings to use more colors

(or levels of gray). Typically, you make this adjustment by opening

Display in Windows Control Panel.

● Try adjusting the resolution and color settings in the scanner software.

The original might have been loaded incorrectly.

The scanner might be dirty.

Use the media guides when you load the originals into the ADF.

Clean the scanner glass. See


The graphics settings might not be suitable for the type of scan job that you are performing.

Try changing the graphics settings.

ENWW Scan problems 163


Problem

Part of the image did not scan.

The scan takes too long

Cause Solution


A colored background might be causing images in the foreground to blend into the background.

Use the media guides when you load the originals into the ADF.

Try adjusting the settings before you scan the original or enhancing the image after you scan the original.

The original is longer than 381 mm (15 inches).

The maximum scannable length is

381 mm (15 inches) when you use the automatic document feeder (ADF) input tray. If the page exceeds the maximum length, the scanner stops. (Copies can be longer.)

The original is too small.

The media size is incorrect.

The resolution or color level is set too high.

The software is set to scan in color.

A print job or copy job was sent before you tried to scan.

CAUTION:

Do not try to pull the original from the ADF; you might damage the scanner or your original. See

Clear jams from the ADF on page 151

.

The minimum size that the flatbed scanner supports is 25 x 25 mm (1 x

1 inch). The minimum size that the ADF supports is 127 x 127 mm (5 x 5 inches).

The original might be jammed. See

Clear jams from the ADF on page 151

.

In Scan settings, make sure that the input media size is large enough for the document that you are scanning.

Change the resolution and color level settings to the correct settings for your job.

The system default is color, which takes longer to scan even when scanning a monochrome original. If you acquire an image through TWAIN or WIA, you can change the settings so that the original scans in grayscale or black-and-white.

See the product software Help for details.

If someone sent a print job or copy job before you tried to scan, the scan will start if the scanner is not busy. However, because the product and scanner share memory, the scan might be slower.



Scan-quality problems

Prevent problems

The following are a few simple steps you can take to improve copy and scan quality.

●

Use the flatbed scanner, rather than the automatic document feeder (ADF) input tray, to scan.

● Use high-quality originals.

●

Load the media correctly. If the media is loaded incorrectly, it might skew, which causes unclear images.

● Adjust the software settings according to how you plan to use the scanned page.

●

If your product frequently feeds more than one page at a time, you might need to replace the separation pad.

● Use or make a carrier sheet to protect your originals.

Solve scan-quality problems

Problem

Blank pages

Too light or dark

Unwanted lines

Black dots or streaks

Unclear text

Description Solution

The original might have been loaded upside down.

In the automatic document feeder (ADF), put the top end of the stack of originals into the ADF input tray, with the media stack face-up and the first page to be scanned on top of the stack.

On the flatbed scanner, place the original document face-down with the upper-left corner of the document at the corner indicated by the icon on the product.

The resolution and color levels might be set incorrectly.

Verify that you have the correct resolution and color settings.

ENWW Scan problems 165


Copy problems

Prevent problems

The following are a few simple steps you can take to improve copy quality:

●

Copy from the flatbed scanner. This will produce a higher quality copy than copying from the automatic document feeder (ADF).

● Use quality originals.

●

Load the media correctly. If the media is loaded incorrectly, it might skew, causing unclear images and problems with the OCR program.

● Use or make a carrier sheet to protect your originals.

NOTE:

Verify that the media meets HP specifications. If the media meets HP specifications, recurring feed problems indicate the pickup roller or separation pad is worn.

Image problems

Problem

Images are missing or faded.

Cause

The print-cartridge toner-level might be low.

The original might be of poor quality.

The original might have a colored background.

Solution

Shared telephone line: a telephone line that receives or sends voice calls and faxes. A single, shared telephone line can perform only one function at a time. A fax cannot be sent while someone is talking on the telephone or while a computer is connecting to the Internet.

◦

Roll-over lines: a telephone system feature that allows an incoming call to be forwarded to the next available telephone line (used with multiple-telephone-line systems). Try attaching the device to the first incoming telephone line. The product will answer the telephone after it rings the number of times that is specified in the product rings-to-answer setting.

◦

PBX system: a business-environment telephone system. Standard home telephones and the

HP LaserJet product use an analog telephone signal. Some PBX systems are digital and might be incompatible with standard telephones and with devices such as the HP LaserJet product.

◦ Distinctive ring service: a telephone system feature that can assign two telephone numbers to one physical line, and assign a distinctive ring pattern to each number. Make sure that the device is set to respond to the correct distinctive ring pattern that the telephone service provider assigned to the fax number. This service is not available in all countries/regions.

Make sure that the telephone company provides this service before changing the setting. For more information about distinctive ring service, see

Distinctive ring function on page 64 .

●

Is a telephone-line splitting device installed?

◦ A telephone-line splitter is a device that splits two or more telephone lines from the same jack.

Not all splitters are compatible with the device, and not all countries/regions support the use of splitters.

Parallel splitters (also called T-splitters) split a single line into two phone jacks so that two devices can share the same line. Line 1/Line 2 splitters provide two unique telephone line outlets from a single jack with two unique telephone numbers (two telephone lines are connected to a single jack). A Line 1/Line 2 splitter must be used if both a fax line and a voice line share the same jack.

NOTE:

Hewlett-Packard does not recommend using a parallel splitter (T-splitter) with the product because it might degrade the quality of the telephone signal. If a second device must be attached to the telephone line in addition to the product, plug the second device into the telephone port on the product (the port on the back that is marked with a telephone icon).



●

Is a surge-protection device installed?

◦

A surge-protection device might be installed between the telephone jack and the product to protect the product from electrical power that passes through the telephone lines. These devices might cause some fax communication problems by degrading the quality of the telephone signal. If you are having problems sending or receiving faxes, connect the device directly to the telephone jack to determine if the problem is in the surge-protection device.

●

Is a telephone company voice-message service being used?

◦

If the messaging service rings-to-answer setting is lower than the product rings-to-answer setting, the messaging service answers the call and the product will not detect incoming faxes.

If the product rings-to-answer setting is lower than that of the messaging service, the product answers all calls and no calls will ever be sent to the messaging service. The only voicemessaging system that can be used with the product is a standard telephone-answering machine.

●

Is a standard telephone-answering machine installed?

◦

An answering machine must be connected to the port that is labeled with the telephone icon

(or it can be shared on the same telephone-line extension). Set the product rings-to-answer setting for at least one ring more than the number of rings that prompts the answering machine to answer a incoming call. For example, if the answering machine is set to answer calls after three rings, set the product rings-to-answer setting to four rings.

NOTE:

If an answering machine is connected to the same telephone line but is connected to a different jack (for example, in another room), it might interfere with the product to fax reception.

Problems receiving faxes

Use the table in this section to solve problems that might occur when receiving faxes.

NOTE:

You must use the fax cord that came with the product in order to ensure that the product functions correctly.

Problem

The product cannot receive faxes from an extension telephone.

Cause

The extension-telephone setting might be disabled.

The fax cord might not be securely connected.

The product dialing mode might be incorrectly set, or the extension phone might be incorrectly set.

Solution

Verify that the extension-telephone setting is enabled.

Verify that the fax cord is securely connected between the telephone jack and the product (or another device that is connected to the product). Press 1-2-3 in sequence (tone-dial mode only), wait for three seconds, and then hang up.

Verify that the product dialing mode is set to Tone. Verify that the extension phone is set to On for tone dialing as well.

ENWW Fax problems (fax models only) 171


Problem

The product is not answering incoming fax calls.

Cause Solution

The answer mode might be set to

Manual.

If the answer mode is set to Manual, the product does not answer calls. You have to start the fax-receiving process manually.

The rings-to-answer setting might not be set correctly.

Check the rings-to-answer setting for your configuration.

The answer-ring pattern feature might be turned on, but you do not have the service, or you do have the service and the feature is not set correctly.

Check the answer-ring pattern feature to verify that it is set properly.

The fax cord might not be correctly connected, or the fax cord is not working.

See the Getting Started Guide to check the installation. Verify that you are using the fax cord that came with the product.

The product might not be able to detect incoming fax tones because the answering machine is playing a voice message.

Re-record your answering machine message, leaving at least two seconds of silence at the beginning of the message.

Too many devices might be connected to the telephone line.

You should not have more than three devices attached to the line. Try removing the last device that was connected and determine whether the product works. If not, continue removing devices one at a time and retry after removing each one.

The telephone line might not be working. Do one of the following:

●

Increase the volume on the product, and then press Start Fax on the control panel. If you hear a dial tone, the telephone line is working.

● Disconnect the product from the telephone jack, and then connect a telephone. Try to make a telephone call to verify that the telephone line is working.

The product will answer all incoming calls.

Refill the media input tray. Press OK . The product prints all of the faxes it has saved in memory and then resumes answering fax calls.

Load media. Any faxes that are received while the input tray is empty are stored in memory and will print after the tray has been refilled.

Check to determine whether the computer is receiving faxes.

Turn on the auto reduction setting.

Received faxes are too light or are printing only on half of the page.

The incoming faxes might have been sent on larger media.

The product ran out of toner while printing a fax.

The fax that was sent was too light.

Adjust the auto reduction setting to allow larger pages to be printed on one page.

The product stores the most recently printed faxes. (The amount of memory that is available determines the actual number of faxes stored for reprinting.) As soon as possible, replace the print cartridge, and then reprint the fax.

Contact the sender and have the sender resend the fax after altering the settings.



Problems sending faxes


The document stops feeding in the middle of faxing.

Faxes stop during sending.

The maximum length of a page that you can load is 381 mm (15 inches). Faxing of a longer page stops at 381 mm (15 inches).

Print the document on shorter media.

If no jam exists and less than one minute has elapsed, wait a moment before pressing Cancel . If a jam exists, see

Clear jams on page 149 . Then, resend

the job.

If the item is too small, it can jam inside the automatic document feeder (ADF).

Use the flatbed scanner. The minimum page size for the ADF is 127 x 127 mm

(5 x 5 inches).

If a jam exists, see

●

Disconnect the product from the telephone jack and connect a telephone. Try to make a telephone call to verify that the telephone line is working.

To stop the redials while the product is dialing, press Cancel .




Faxes that you send are not arriving at the receiving fax machine.

Faxes you send include a block of gray shading at the end of each page.

The receiving fax machine might be off or might have an error condition, such as being out of paper.

Call the recipient to verify that the fax machine is on and ready to receive faxes.

The originals might be incorrectly loaded. Verify that the original documents are correctly loaded into the ADF input tray or flatbed scanner.

A fax might be in memory because it is waiting to redial a busy number, other jobs that are ahead of it are waiting to be sent, or the fax is set up for a delayed send.

If a fax job is in memory for any of these reasons, an entry for the job appears in the fax log. Print the fax activity log and check the Status column for jobs that show a Pending designation.

You might be sending a fax from the flatbed scanner with the glass-fax size set incorrectly.

Verify that the setting is correct.

Faxes you send have data missing from the end of each page.

You might be sending a fax from the flatbed scanner with the glass-fax size set incorrectly.

You receive a Low Memory error.

Verify that the setting is correct.

You might be sending a fax that is too large, or the resolution might be too high.

Try one of the following:

● Divide a large fax into smaller sections, and then fax them individually.

●

Clear stored faxes to make more memory available for outgoing faxes.

● Configure the outgoing fax as a delayed fax, and then verify that it will send completely.

●

Make sure that you are using the lowest resolution setting

(Standard).

Voice-call problems

Problem

The telephone or answering machine that is connected to the line is not receiving voice calls.

Cause

The fax cord might not be correctly connected.

The answer mode or rings-to-answer settings might not be correctly set.

The answering machine or telephone might not be functioning.

The problem persists.

Solution

See the Getting Started Guide to check the installation. The product must be the first device connected to the telephone line.

The rings-to-answer must be set higher than the answering machine setting.

Connect the telephone or answering machine directly to the telephone line and determine if it works by itself.

See the Fax chapter in the product user guide.



Media-handling problems

NOTE:

For information about removing jams, see Clear jams on page 149 .

Problem

Print is skewed (crooked).

Pages are curled or wrinkled.

Cause Solution

The media input tray might be overloaded.

The media guides might be incorrectly set, broken, or missing.

Remove some of the media from the input tray.

Verify that the guides are not adjusted too tightly or too loosely against the paper. Check for broken or missing guides, and replace them if necessary.



HP specifications.


HP specifications.


The media is not stored properly.

When possible, store media in its sealed ream at room temperature.

The media has been in the input tray too long.

Turn over the stack of media in the tray or rotate the media 180° in the paper tray.



Performance problems


Faxes are transmitting or being received very slowly.

The fax might be very complex, such as one with many graphics.

Complex faxes take longer to be sent or received. Breaking longer faxes into multiple jobs can increase the transmission speed.

The receiving fax machine might have a slow modem speed.

The product only sends the fax at the fastest modem speed that the receiving fax machine can accept.

The resolution at which the fax was sent or is being received might be very high.

If you are receiving the fax, call and ask the sender to lower the resolution and resend the fax. If you are sending the fax, lower the resolution and resend the fax.


Hang up and resend the fax. Have the telephone company check the telephone line.

The fax activity logs or fax call reports are printing at inappropriate times.

You are sending a fax via an international call.

You must allow more time to transmit fax jobs internationally.

The fax activity log or fax call reports settings are not correct.

Print a configuration page and check when the reports print.

The product sounds are too loud or too soft.

The volume setting might not be adjusted correctly.

Adjust the volume setting.



Functional checks

Engine test page

1.

Turn the product power on and wait for the message Ready to appear on the control-panel display.

2.

Rapidly open and then close the print-cartridge door five times.

CAUTION:

Do not forcibly close the door to prevent damaging the door latches.

TIP:

Depress and hold down the print-cartridge door button to prevent the door latches from engaging. Open the door far enough to activate the door open sensor, and then fully close the door.

3.

An engine test page prints.

Drum rotation test

The photosensitive drum, located in the print cartridge, must rotate in order for the print process to work.

The photosensitive drum receives its drive from the main drive assembly.

NOTE:

This test is especially important if refilled print cartridges have been used.

1.


2.

Remove the print cartridge.

3.

Mark the drive gear on the cartridge with a felt-tipped marker. Note the position of the mark.

4.

Install the print cartridge and close the print-cartridge door. The startup sequence should rotate the drum enough to move the mark.

5.

Open the print-cartridge door and inspect the gear that was marked in step 3. Verify that the mark moved.

If the mark did not move, inspect the main drive assembly to make sure that it is meshing with the print cartridge gears. If the drive gears appear functional and the drum does not move, replace the print cartridge.



Half self-test functional check

The print process can be subdivided into the following stages:

●

Image formation stage (charges the drum and writes a latent image to the drum with the laser)

●

Development stage (forms a toner image on the drum)

●

Transfer stage (transfers the image to the media)

● Cleaning stage (removes excess toner from the drum)

●

Fusing stage (applies heat and pressure to the media to make the image permanent)

Perform a half self-test check

The purpose of the half self-test check is to determine which process is malfunctioning.

1.

Print a configuration page.

2.

Open the print cartridge access door after the paper advances halfway through the product

(approximately five seconds after the motor begins rotating). The leading edge of the paper should have advanced past the print cartridge.

3.

Remove the print cartridge.

4.

Open the print cartridge drum shield to view the drum surface. If a dark and distinct toner image is present on the drum surface, assume that the first two functions of the electrophotographic process are functioning (image formation and development). Problem solve the failure as a transfer or fusing problem.

Perform other checks

If no image appears on the photosensitive drum, perform these checks:

1.

Make sure that you removed the entire length of the sealing tape from the print cartridge before you installed the cartridge.

2.

Perform a drum-rotation functional check to ensure that the drum is rotating (see

Drum rotation test on page 178 ).

3.

Perform a high-voltage power-supply check. See Heating element check on page 180 .

ENWW Functional checks 179


Heating element check

Media passes between the heating element and a soft pressure roller to fuse toner to the media.

1.

Unplug the product for at least ten minutes.

2.

Verify that the thermistor connector is seated into both the product chassis and the ECU.

3.

Remove the heating element connector from the ECU. To measure the continuity of the heating element, measure the resistance between the two pins at the end of the cable.

NOTE:

Normal resistance is 25 ohms +/- 10 ohms for the 110 V product and 80 ohms +/- 20 ohms for the 220 V product.

If no resistance is measured, replace the fuser.

4.

Remove the thermistor connector, and then measure the resistance between J206 pins one and two and between J206 pins three and four.

NOTE:

Normal resistance between both pairs of pins is 370K ohms +/- 50K ohms at 20°C (68°

F).

5.

If no resistance is measured, replace the fuser.

High-voltage contacts check

The high-voltage contacts in the product must have a good connection with the contacts on the print cartridge to provide the necessary voltages for the electrophotographic processes.

Check the print-cartridge contacts

Remove the print cartridge and visually inspect the three connection points on the ends of the print cartridge: drum ground (callout 1), charging (callout 2), and developing roller (callout 3). If they are dirty or corroded, clean the connection. If they are damaged, replace the print cartridge.

NOTE:

Use only isopropyl alcohol to clean the connections.

Parts lists and diagrams

How to use the parts lists and diagrams

The figures in this chapter show the major subassemblies in the product and their component parts. A parts list table follows each exploded view assembly diagram. Each table lists the item number, the associated part number, and the description of each part. If a part is not listed in the table, then it is not a field replaceable unit (FRU).

CAUTION:

Be sure to order the correct part. When looking for part numbers for electrical components, pay careful attention to the voltage that is listed in the description column to ensure that the part number selected is for the correct product model.

NOTE:

In this manual, the abbreviation “PCA” stands for “printed circuit board assembly.” Components described as a PCA might consist of a single circuit board or a circuit board plus other parts, such as cables and sensors.

A Service and support

Hewlett-Packard limited warranty statement

HP PRODUCT

HP LaserJet M1522n and M1522nf

DURATION OF LIMITED WARRANTY

One-year limited warranty

HP warrants to you, the end-user customer, that HP hardware and accessories will be free from defects in materials and workmanship after the date of purchase, for the period specified above. If HP receives notice of such defects during the warranty period, HP will, at its option, either repair or replace products which prove to be defective.

Replacement products may be either new or equivalent in performance to new.

HP warrants to you that HP software will not fail to execute its programming instructions after the date of purchase, for the period specified above, due to defects in material and workmanship when properly installed and used. If

HP receives notice of such defects during the warranty period, HP will replace software which does not execute its programming instructions due to such defects.

HP does not warrant that the operation of HP products will be uninterrupted or error free. If HP is unable, within a reasonable time, to repair or replace any product to a condition as warranted, you will be entitled to a refund of the purchase price upon prompt return of the product.

HP products may contain remanufactured parts equivalent to new in performance or may have been subject to incidental use.

Warranty does not apply to defects resulting from (a) improper or inadequate maintenance or calibration, (b) software, interfacing, parts or supplies not supplied by HP, (c) unauthorized modification or misuse, (d) operation outside of the published environmental specifications for the product, or (e) improper site preparation or maintenance.

TO THE EXTENT ALLOWED BY LOCAL LAW, THE ABOVE WARRANTIES ARE EXCLUSIVE AND NO OTHER

WARRANTY OR CONDITION, WHETHER WRITTEN OR ORAL, IS EXPRESSED OR IMPLIED AND HP

SPECIFICALLY DISCLAIMS ANY IMPLIED WARRANTIES OR CONDITIONS OF MERCHANTABILITY,

SATISFACTORY QUALITY, AND FITNESS FOR A PARTICULAR PURPOSE. Some countries/regions, states or provinces do not allow limitations on the duration of an implied warranty, so the above limitation or exclusion might not apply to you. This warranty gives you specific legal rights and you might also have other rights that vary from country/region to country/region, state to state, or province to province. HP's limited warranty is valid in any country/ region or locality where HP has a support presence for this product and where HP has marketed this product. The level of warranty service you receive may vary according to local standards. HP will not alter form, fit or function of the product to make it operate in a country/region for which it was never intended to function for legal or regulatory reasons.

TO THE EXTENT ALLOWED BY LOCAL LAW, THE REMEDIES IN THIS WARRANTY STATEMENT ARE YOUR

SOLE AND EXCLUSIVE REMEDIES. EXCEPT AS INDICATED ABOVE, IN NO EVENT WILL HP OR ITS

SUPPLIERS BE LIABLE FOR LOSS OF DATA OR FOR DIRECT, SPECIAL, INCIDENTAL, CONSEQUENTIAL

ENWW Hewlett-Packard limited warranty statement 239


(INCLUDING LOST PROFIT OR DATA), OR OTHER DAMAGE, WHETHER BASED IN CONTRACT, TORT, OR

OTHERWISE. Some countries/regions, states or provinces do not allow the exclusion or limitation of incidental or consequential damages, so the above limitation or exclusion may not apply to you.

THE WARRANTY TERMS CONTAINED IN THIS STATEMENT, EXCEPT TO THE EXTENT LAWFULLY

PERMITTED, DO NOT EXCLUDE, RESTRICT OR MODIFY AND ARE IN ADDITION TO THE MANDATORY

STATUTORY RIGHTS APPLICABLE TO THE SALE OF THIS PRODUCT TO YOU.

Customer self repair warranty service

HP products are designed with many Customer Self Repair (CSR) parts to minimize repair time and allow for greater flexibility in performing defective parts replacement. If during the diagnosis period, HP identifies that the repair can be accomplished by the use of a CSR part, HP will ship that part directly to you for replacement. There are two categories of CSR parts: 1) Parts for which customer self repair is mandatory. If you request HP to replace these parts, you will be charged for the travel and labor costs of this service. 2) Parts for which customer self repair is optional. These parts are also designed for

Customer Self Repair. If, however, you require that HP replace them for you, this may be done at no additional charge under the type of warranty service designated for your product.

Based on availability and where geography permits, CSR parts will be shipped for next business day delivery. Same-day or four-hour delivery may be offered at an additional charge where geography permits. If assistance is required, you can call the HP Technical Support Center and a technician will help you over the phone. HP specifies in the materials shipped with a replacement CSR part whether a defective part must be returned to HP. In cases where it is required to return the defective part to HP, you must ship the defective part back to HP within a defined period of time, normally five (5) business days. The defective part must be returned with the associated documentation in the provided shipping material. Failure to return the defective part may result in HP billing you for the replacement. With a customer self repair, HP will pay all shipping and part return costs and determine the courier/carrier to be used.

IMPLIED AND HP SPECIFICALLY DISCLAIMS ANY IMPLIED WARRANTIES OR CONDITIONS OF

MERCHANTABILITY, SATISFACTORY QUALITY, AND FITNESS FOR A PARTICULAR PURPOSE.

Maintenance agreements are not part of the standard warranty. Support services may vary by area.

Check with your local HP dealer to determine the services available to you.

Repacking the device

If HP Customer Care determines that your device needs to be returned to HP for repair, follow the steps below to repack the device before shipping it.

CAUTION:

Shipping damage as a result of inadequate packing is the customer’s responsibility.

1.

Remove and retain the print cartridge.

CAUTION:

It is extremely important to remove the print cartridge before shipping the device. A print cartridge that remains in the device during shipping will leak and entirely cover the device engine and other parts with toner.

To prevent damage to the print cartridge, avoid touching the roller on it, and store the print cartridge in its original packing material or so that it is not exposed to light.

2.

Remove and retain the power cable, interface cable, and optional accessories.

3.

If possible, include print samples and 50 to 100 sheets of paper or other print media that did not print correctly.

4.

In the U.S., call HP Customer Care to request new packing material. In other areas, use the original packing material, if possible. Hewlett-Packard recommends insuring the equipment for shipment.

Extended warranty

HP Support provides coverage for the HP hardware product and all HP-supplied internal components.

The hardware maintenance covers a 1- to 3-year period from date of the HP product purchase. The customer must purchase HP Support within the stated factory warranty. For more information, contact the HP Customer Care Service and Support group.

The Telephone Consumer Protection Act of 1991 makes it unlawful for any person to use a computer or other electronic device, including fax machines, to send any message unless such message clearly contains, in a margin at the top or bottom of each transmitted page or on the first page of the transmission, the date and time it is sent and an identification of the business, other entity, or individual sending the message and the telephone number of the sending machine or such business, other entity, or individual. (The telephone number provided cannot be a 900 number or any other number for which charges exceed local or long-distance transmission charges.)

IC CS-03 requirements

Notice: The Industry Canada label identifies certified equipment. This certification means the equipment meets certain telecommunications network protective, operational, and safety requirements as prescribed in the appropriate Terminal Equipment Technical Requirement document(s). The

Department does not guarantee the equipment will operate to the user’s satisfaction. Before installing this equipment, users should ensure that it is permissible for the equipment to be connected to the facilities of the local telecommunications company. The equipment must also be installed using an acceptable method of connection. The customer should be aware that compliance with the above conditions may not prevent degradation of service in some situations. Repairs to certified equipment should be coordinated by a representative designated by the supplier. Any repairs or alterations made by the user to this equipment, or equipment malfunctions, may give the telecommunications company cause to request the user to disconnect the equipment. Users should ensure for their own protection that the electrical ground connections of the power utility, telephone lines, and internal metallic water pipe system, if present, are connected together. This precaution can be particularly important in rural areas.

CAUTION:

Users should not attempt to make such connections themselves, but should contact the appropriate electric inspection authority, or electrician, as appropriate. The Ringer Equivalence Number

(REN) of this device is 0.7.

Notice: The Ringer Equivalence Number (REN) assigned to each terminal device provides an indication of the maximum number of terminals allowed to be connected to a telephone interface. The termination on an interface may consist of any combination of devices subject only to the requirement that the sum of the Ringer Equivalence Number of all the devices does not exceed five (5.0). The standard connecting arrangement code (telephone jack type) for equipment with direct connections to the telephone network is CA11A.

Safety statements

Laser safety

The Center for Devices and Radiological Health (CDRH) of the U.S. Food and Drug Administration has implemented regulations for laser products manufactured since August 1, 1976. Compliance is mandatory for products marketed in the United States. The device is certified as a “Class 1” laser product under the U.S. Department of Health and Human Services (DHHS) Radiation Performance Standard according to the Radiation Control for Health and Safety Act of 1968. Since radiation emitted inside the device is completely confined within protective housings and external covers, the laser beam cannot escape during any phase of normal user operation.

WARNING!

Using controls, making adjustments, or performing procedures other than those specified in this user guide may result in exposure to hazardous radiation.

Canadian DOC regulations

Complies with Canadian EMC Class B requirements.
