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.

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

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).
50 Chapter 4 Operational theory ENWW
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.
52 Chapter 4 Operational theory ENWW
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.

Pickup/feed/delivery system
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.

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
Image-formation system
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:
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.
60 Chapter 4 Operational theory ENWW
ENWW
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

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.

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.
64 Chapter 4 Operational theory ENWW
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.
ENWW Fax functions and operation (fax models only) 65
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.
66 Chapter 4 Operational theory ENWW
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
ENWW Fax functions and operation (fax models only) 67
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.
Never operate or service the product with the protective cover removed from the laser/scanner assembly. The invisible reflected beam can damage your eyes.

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.

ENWW Scan problems 163
Problem
Part of the image did not scan.
The scan takes too long
Cause Solution
The original might have been loaded incorrectly.
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.

Fax problems (fax models only)
General fax problem-solve
Verify the following information before problem-solving fax problems.
● Is the fax set up correctly?
◦
Make sure that the fax cord that came with the product is the cord that is being used. This cord has been tested and meets the device specifications.
◦ Make sure that the fax cord is installed in the correct port. The fax cord must be plugged into the line port.
●
What type of telephone line is being used?
◦ Dedicated telephone line: a unique telephone line that is assigned to receive or send a fax.
The fax cord must be plugged into the line port.
◦
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).
170 Chapter 6 Problem solve ENWW
●
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.

● 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.

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.
Use media that meets HP specifications.
The media might not meet
HP specifications.
The media might not meet
HP specifications.
Use media that meets HP specifications.
The media is not stored properly.

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.
176 Chapter 6 Problem solve ENWW
Performance problems
Problem Cause Solution
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.
Your telephone line might not be working.
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.
Open the print-cartridge door.
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.
178 Chapter 6 Problem solve ENWW
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.
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.

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.

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.

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.

On the back of this equipment is a label that contains, among other information, the FCC registration number and ringer equivalence number (REN) for this equipment. If requested, this information must be provided to the telephone company. The REN is used to determine the quantity of devices which may be connected to the telephone line. Excessive RENs on the telephone line may result in the devices not ringing in response to an incoming call. In most, but not all, areas, the sum of the RENs should not exceed five (5.0). To be certain of the number of devices that may be connected to the line, as determined by the total RENs, contact the telephone company to determine the maximum REN for the calling area.

Telephone Consumer Protection Act (United States)
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.
