Sequence of operation

The DC controller in the engine-control system controls the operational sequences of the product. The table below describes durations and operations for each period of a print operation from when the product is turned on until the motor stops rotating.

NOTE:

This sequence of operations is for the product base and does not include the document feeder.

Normal sequence of operation

Table 1-1 Sequence of operation

Name Timing

WAIT From the time the power switch is turned on, the door is closed or the product exits Sleep mode until the product gets ready for a print operation.

STBY (standby)

INTR (initial rotation)

PRINT

LSTR (last rotation)

From the end of the WAIT or LSTR period until either a print command is sent or the power switch is turned off.

From the time a print command is received until the paper is picked up.

From the end of the INTR period until the last sheet completes the fuser operation.

From the end of the PRINT period until the main motor stops rotating.

Purpose

Brings the product to ready state. The product performs the following during the operations:

Detects the toner cartridge

● Heats the fuser film in the fuser

Rotates, and the stops, the main motor

Maintains the product in printable condition. The product performs the following during the operation:

The product performs the following during the operations:

Drives the main motor

● Activates the high-voltage power supply

Activates the laser/scanner

● Warms the fuser heater

Forms the image on the photosensitive drum based on the VIDEO signals from the formatter. Transfers and fuses the toner image to the paper.

Moves the last printed sheet out of the product. The product performs the following during the operations:

● Stops the main motor

Deactivates the high-voltage power supply

● Deactivates the laser/scanner

Deactivates the fuser heater

The product enters the INTR period as the LSTR period is completed, if the formatter sends another print command.

ENWW Basic operation 3

Formatter-control system

The formatter is responsible for the following procedures:

Controlling sleep mode

● Receiving and processing print data from the various product interfaces

Monitoring control-panel functions and relaying product-status information (through the control panel and the network or bidirectional interface)

● Developing and coordinating data placement and timing with the DC controller PCA

Storing font information

● Communicating with the host computer through the network or the bidirectional interface

The formatter receives a print job from the network or bidirectional interface and separates it into image information and instructions that control the printing process. The DC controller PCA synchronizes the imageformation system with the paper-input and -output systems, and then signals the formatter to send the print-image data.

Sleep mode

After a user-specified time, the Sleep mode feature automatically conserves electricity by substantially reducing power consumption when the product is not printing. After a user-specified time, the product automatically reduces its power consumption (Sleep mode). The product returns to the ready state when a button is pressed, a print job is received, or a door is opened. When the product is in Sleep mode, all of the control-panel LEDs and the power button backlight LED is blinking or on.

NOTE:

Although the product lights are off in Sleep mode, the product functions normally when it receives a print job.

Input/output

The product receives print data primarily from the following:

● Hi-Speed USB 2.0 port

● 10/100 Base-T network port.

● Fax

● Wireless

CPU

The formatter incorporates a 600 MHz processor.

Memory

The random access memory (RAM) on the formatter PCA contains the page and the I/O buffers. RAM stores printing information received from the host system, and can also serve to temporarily store a full page of print-image data before the data is sent to the print engine.

4 Chapter 1 Theory of operation ENWW

Firmware

● The product has 128 MB of Synchronous DRAM, which is used for run-time firmware imaging and print, fax, scan and copy job information during printing.

PJL overview

The printer job language (PJL) is an integral part of configuration, in addition to the standard printer command language (PCL). With standard cabling, the product can use PJL to perform a variety of functions such as these:

● Two-way communication with the host computer through a network connection or a USB connection.

The product can inform the host about such things as the control-panel settings, and the control-panel settings can be changed from the host.

Dynamic I/O switching. The product uses this switching to be configured with a host on each I/O. The product can receive data from more than one I/O simultaneously, until the I/O buffer is full. This can occur even when the product is offline.

● Context-sensitive switching. The product can automatically recognize the personality (PS or PCL) of each job and configure itself to serve that personality.

Isolation of print environment settings from one print job to the next. For example, if a print job is sent to the product in landscape mode, the subsequent print jobs print in landscape mode only if they are formatted for landscape printing.

LEDM overview

The low-end data model (LEDM) provides one consistent data representation method and defines the dynamic and capabilities tickets shared between clients and devices, as well as the access protocol, event, security, and discovery methods.

ACL overview

The advanced control language (ACL) is a language that supports product control and firmware downloads in printers that support both PJL/PCL and host-based printing. Each sequence of ACL commands must be preceded by a unified exit command (UEL) and an @PJL ENTER LANGUAGE=ACL command. The ACL sequence is always followed by a UEL. Any number of commands can be placed between the UELs. The only exception to these rules is the download command. If a firmware download is done, the download command must be the last command in the sequence. It will not be followed by a UEL.

The firmware searches for the UEL sequence when parsing commands. However, while downloading binary data such as host-based code or NVRAM data the firmware suspends UEL parsing. To handle hosts that

“disappear” during binary sequences, the firmware times out all ACL command sessions. If a timeout occurs during a non-download command sequence, it is treated as the receipt of a UEL. If a timeout occurs during firmware download the product resets.

Control panel

The formatter sends and receives product status and command data to and from the control-panel PCA.

Fuser failure detection

The DC controller determines a fuser unit failure, releases the relay to interrupt power supply to the fuser heater, and notifies the formatter of a failure state when it encounters the following conditions:

Start up failure

◦ If the main thermistor does not detect a specified temperature during the start up process of the heater in the wait period.

If the main thermistor does not detect a specified temperature during the heater temperature control in the initial rotation period.

● Abnormal low temperature

If the main thermistor detects an abnormal low temperature of the fuser unit during the printing operation.

● Abnormal high temperature

If the main thermistor detects an abnormal high temperature of the fuser unit.

● Frequency detection circuit failure

If a specified frequency of the FREQUENCY signal is not detected within a specified period after the product is turned on.

12 Chapter 1 Theory of operation ENWW

Fuser temperature control

The fuser temperature control maintains the temperature of the fuser heater at its targeted temperature.

The DC controller monitors the FIXING TEMPERATURE (FSRTH) signals and sends the FIXING HEATER CONTROL

(FSRD) signal according to the detected temperature. The fuser heater control circuit controls the fuser heater depending on the signal so that the heater remains at the targeted temperature.

Fuser protective function

The protective function detects an abnormal temperature rise of the fuser unit and interrupts power supply to the fuser heater.

The following three protective components prevent an abnormal temperature rise of the fuser heater:

● DC controller

The DC controller interrupts power supply to the fuser heater when it detects an abnormal temperature of the fuser heater.

● Fuser heater safety circuit

The fuser heater safety circuit interrupts power supply to the fuser heater when the detected temperature of the main thermistor is abnormal.

● Thermal fuse

The contact of the thermal fuse is broken to interrupt power supply to the fuser heater when the thermal fuse detects an abnormal temperature of the fuser heater.

Pressure roller cleaning

The pressure roller cleaning process is initiated by the formatter. The process removes toner that has accumulated on the pressure roller by transferring it to a sheet of blank paper.

NOTE:

Use plain paper, with a weight of 75 g/m 2 (20 lb), for the pressure roller cleaning.

The product feeds a sheet of paper after receiving the cleaning command from the formatter.

● Main motor rotation is stopped when the trailing edge of the paper passes through the transfer roller.

The main motor rotation is repeatedly started and then stopped. The fuser heater is turned on and then off at the same interval as main motor rotation.

● Toner adhered to the pressure roller is fused to the paper.

The paper is ejected from the product.

Over-current/over-voltage protection

The low-voltage power supply automatically stops supplying the DC voltage to the printer components whenever it detects excessive current or abnormal voltage.

The low-voltage power supply has a protective circuit against over-current and over-voltage to prevent failures in the power supply circuit.

If DC voltage is not being supplied from the low-voltage power supply, the protective function might be running. In this case, turn the power switch off and unplug the power cord. Do not turn the power switch on until the root cause is found and corrected.

WARNING!

If you believe the over-current or over-voltage protection circuits have been activated, do not plug in the product power cord or turn on the product power until the cause of the failure is found and corrected.

The DC controller notifies the formatter of a low-voltage power supply failure when the protective function is activated.

In addition, the low-voltage power supply has one fuse (FU101) to protect against over-current. If excessive current flows into the AC line, the fuse blows to stop AC power.

Toner acquires a negative charge from the friction that occurs when the developing roller rotates against the developing blade. The developing bias is applied to the developing roller to make a potential difference between the developing roller and the photosensitive drum. The negatively charged toner is attracted to the latent image on the photosensitive drum because the drum surface has a higher potential.

Step 4: The transfer charging roller, to which a DC positive bias is applied, imparts a positive charge on the paper. When the page comes in contact with the photosensitive drum, the toner is transferred to the paper.

Scanner system

The flatbed image scanner captures an electronic image of the document on the glass. The scanner does this by illuminating the document with LEDs (red, green, and blue) and capturing the image in the image sensor to create an electronic format of the document. The flatbed scanner consists of three main elements

CIS scanner. The CIS (contact image sensor) scanner captures an image using the product's optical path.

Red, green, and blue LEDs sequentially illuminate a small strip of the document (often called a raster line), and the optical system captures each color in a single row of CCD sensors that cover the entire page width. Because only one color is captured for each line per exposure, the three colors are recombined electronically to create the full color image. For monochromatic scans or copies, all three

LEDs are illuminated to create a white light for the scan so the raster line can be captured in one exposure.

Mechanical carriage drive. The carriage drive moves the CIS scan head along the document length to create the image. In this product, a small DC motor with an optical encoder creates this motion. The speed of the carriage drive is proportional to the scan resolution (300 ppi is much faster than 1200 ppi) and also proportional to the type of scan (color scans are three-times slower than monochromatic scans). A 1200 ppi color scan moves so slowly that the product may appear to not be working, whereas a monochromatic copy scan moves at 50 times that speed and will be a little noisy.

Image processing system (formatter). The formatter processes the scanner data into either a copy or a scan to the computer. For copies, the image data is sent directly to the product without being transmitted to the computer. Depending on user selections for the copy settings, the formatter enhances the scanner data significantly before sending it to the product. Image data is captured at 300 ppi for copies and is user selectable for scans to the computer. Each pixel is represented by 8 bits for each of the three colors (256 levels for each color), for a total of 24 bits per pixel (24-bit color).

Electrical system

Scanner power-on sequence of events

When the product is turned on, it performs the following tests:

Wall find. The scan carriage moves slowly to the left while watching an encoder on the carriage motor to determine when the carriage has found the left side wall or stop. This enables the product to identify the document origin (position of the original). If the document origin cannot be located, a default position is used instead.

Home find. The scan carriage uses the optical scanner to find physical reference features that relate to the document origin at the left side of the image glass. This process ensures accurate location of the first document pixels so that the user documents will have an accurate placement of the image on scans and copies. If the reference feature is not found, it uses a default value.

Calibration. This test, also known as scanner color calibration, enables the product to identify the black and white on every pixel in the CIS. Calibration occurs in two major processes: a broad (analog) adjustment of all pixels to bring them into the target output range, and a pixel-by-pixel adjustment

(digital) to fine tune the actual black and white response. The calibration process occurs under the left side of flatbed image scanner where there is a special white calibration label.

Calibration is the most important step in creating a high quality image. Calibration problems can include color inaccuracies, brightness inaccuracies, and vertical streaks through the image. The calibration process identifies any bad pixels and enables the image formatter to recreate the lost information from adjacent pixels. Extreme cases of this problem can appear as large vertical streaks or image smears.

ENWW Scanner system 31

You can force a scanner calibration by turning the product on or by performing a color calibration.

Scanner calibration occurs with each of these events.

Copy or scan-to-computer sequence of events

To create an accurate rendition of a document, the scanner must be calibrated for the requested operation. If the user selects a scan at 600 ppi color, the flatbed image scanner calibrates for that specific operational mode. Subsequently, the flatbed image scanner automatically re-calibrates for the next requested operation. Calibration does not occur for every new copy request.

Normal sequence of operation for a flatbed copy or scan includes:

1.

LEDs illuminate.

2.

Carriage motion begins moving the CIS scanner toward the right.

3.

Image capture continues for the entire page or length requested in a scan-to-computer operation.

4.

Carriage returns to the home position on the left.

32 Chapter 1 Theory of operation ENWW

Document feeder functions and operation

The following sections describe how the document feeder functions.

Document feeder operation

Standby (paper-loading) mode: In standby mode, the stopper will be lowered to prevent the user from inserting the original document too far. When a document is inserted correctly, the CIS will detect its presence by the Flag_document status.

The standard operation of the document feeder consists of the pick and feed steps.

Pick: When it receives a copy or scan command, the SSA motor engages the gear train. The first roller, called the pre-pick roller, moves the top few sheets forward into the document feeder. The next roller is the pickup roller. This roller contacts the document feeder separation pad, which separates multiple pages into single sheets.

Feed: The single sheet continues through the path. Along the way, the TOF sensor, which is a set distance from the document feeder 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 by the TOF sensor.

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

Flag_document part

The CIS will detect the presence of the paper from the flag_document (callout 2) status. The document feeder has one sensor that detects paper. If paper is in the document feeder, the TOF sensor (callout 1) detects the top and bottom edges of the document. The TOF sensor detects media moving through the document feeder. If a jam is detected, the document feeder immediately stops the paper from feeding and a jam message is displayed on the control-panel display.

Document feeder functions and operation 33

Document feeder jam detection

The document feeder has one sensor that detects paper. The TOF sensor detects media moving through the document feeder. If a jam is detected, the document feeder 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 document feeder 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 document feeder scanner glass. The document feeder then attempts three times, or for about ten seconds, to advance the paper to the TOF 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 TOF sensor, but the trailing edge is not detected within the time allowed for a 381 mm (15 in) document (the maximum allowable page length for the document feeder), 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 in) long has advanced to the TOF 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 document feeder and the scan module remains under the document feeder scanner glass, an internal firmware error has probably occurred. This is usually remedied by cycling the power.

34 Chapter 1 Theory of operation ENWW

Fax functions and operation

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.

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

Three versions of the fax card are used in the product. One for Asia Pacific countries/regions and the United

States, one for Europe, and one for Brazil. Each version is compliant with the 2/4-wire phone jack system from the respective country/region.

ENWW Fax functions and operation 35

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 data access arrangement (DAA) to comply with worldwide regulatory requirements.

Safety isolation

The most important function of the fax card is the safety isolation between the high-voltage, transient-prone 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 over-current 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 product 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 barrier-critical 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.

36 Chapter 1 Theory of operation ENWW

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 offhook. 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 currentvoltage 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 billing 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.

ENWW Fax functions and operation 37

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 8 MB of flash memory, of which 7.5 MB is available for fax storage.

The remaining 0.5 MB 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 resend the fax in case of errors. The product will resend stored fax pages after a busy signal, communication 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 toner 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 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.

Troubleshooting process

Determine the problem source

The following table includes basic questions to ask the customer to quickly help define the problem.

General topic

Environment

Paper

Input trays

Toner cartridge

Transfer roller and fuser

Toner-cartridge door

Condensation

Miscellaneous

Questions

● Is the product installed on a solid, level surface (± 1°)?

● Is the power-supply voltage within ± 10 volts of the specified power source?

● Is the power-supply plug inserted in the product and the outlet?

● Is the operating environment within the specified parameters?

● Is the product exposed to ammonia gas, such as that produced by diazo copiers or office cleaning materials?

NOTE:

Diazo copiers produce ammonia gas as part of the copying processes.

Ammonia gas (from cleaning supplies or a diazo copier) can have an adverse affect on some product components (for example, the toner-cartridge imaging drum).

● Is the product exposed to direct sunlight?

Does the customer use only supported paper?

● Is the paper in good condition (no curls, folds, or distortion)?

● Is the paper stored correctly and within environmental limits?

● Is the amount of paper in the tray within specifications?

● Is the paper correctly placed in the tray?

● Are the paper guides aligned with the stack?

● Is the toner cartridge installed correctly?

NOTE:

Check for an empty, refilled, or cloned toner cartridge.

● Are the transfer roller and fuser installed correctly?

NOTE:

Check for fuser film damage or a contaminated or dirty transfer roller.

Is the toner-cartridge door closed?

NOTE:

Check for a damaged door interlock switch or cabling.

● Does condensation occur following a temperature change (particularly in winter following cold storage)? If so, wipe affected parts dry or leave the product on for

10 to 20 minutes.

● Was a toner cartridge opened soon after being moved from a cold to a warm room?

If so, allow the toner cartridge to sit at room temperature for 1 to 2 hours.

● Check for and remove any non-HP components (for example, a toner cartridge) from the product.

Remove the product from the network and make sure that the failure is with the product before beginning troubleshooting.

42 Chapter 2 Solve problems ENWW

Power subsystem

Power-on checks

Turn on the power. If the control panel does not illuminate, perform the power-on checks to find the cause of the problem.

1.

Verify that the product is plugged into an active electrical outlet that delivers the correct voltage.

2.

Verify that the power switch is in the on position.

3.

Make sure that the product makes the expected start up sounds.

NOTE:

The over-current/over-voltage protection circuit in the low-voltage power supply unit might be functioning. Turn the product off, unplug the power cord, and turn the product on. If the product does not function, the fuse melts, or the power supply is malfunctioning, replace the engine controller unit.

ENWW Troubleshooting process 43

Tools for troubleshooting

Component diagnostics

Engine diagnostics

Printing test pages helps determine whether the product engine and the formatter are functioning. If the formatter is damaged, it might interfere with the engine test. If the engine-test page does not print, try removing the formatter and then performing the engine test again. If the engine test is then successful, the problem is almost certainly with the formatter.

Engine-test page

NOTE:

The product has an engine-test page in the firmware that is printed by opening and closing the toner-cartridge door in a specific pattern. Use A4 or letter-size paper to print the engine-test page.

1.

Make sure that paper is correctly loaded in the tray.

2.

Turn the product on. Wait for the product to reach the Ready state.

3.

Open, and then close the toner-cartridge door five times at an interval of about two seconds to start the internal engine-test.

4.

If the engine test is successful, an engine-test page prints. The engine-test page has test patterns including horizontal lines, solid black areas, and images.

Drum rotation functional check

The photosensitive drum, located in the toner cartridge, must rotate 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 toner cartridges have been used.

1.

Open the toner-cartridge door.

2.

Remove the toner cartridge.

3.

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

4.

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

5.

Open the toner-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 tonercartridge gears. If the drive gears appear functional and the drum does not move, replace the toner cartridge.

Half self-test functional check

The half self-test check determines which printing process is malfunctioning. This process requires you to stop the product while it is in the process of printing a page.

1.

Print a Configuration page.

2.

Open the toner-cartridge-door after the paper advances halfway through the product (about five seconds after the motor begins rotating). The leading edge of the paper should have advanced past the toner cartridge.

3.

Remove the toner cartridge.

4.

Open the toner-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). Troubleshoot the failure as a transfer or fusing problem.

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

1.

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

2.

Perform a drum rotation functional check to make sure that the drum is rotating.

3.

Make sure that the high-voltage contacts are clean and not damaged.

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.

Environmental product stewardship program

Protecting the environment

Hewlett-Packard Company is committed to providing quality products in an environmentally sound manner.

This product has been designed with several attributes to minimize impacts on our environment.

Ozone production

The airborne emissions of ozone for this product has been measured according to a generally recognized method* and when these emissions data are applied to a “generic office model exposure scenario”**, HP is able to determine there is no appreciable amount of ozone generated during printing that exceeds any current indoor air quality standards or guidelines.

* Test method for the determination of emissions from hardcopy devices with respect to awarding the environmental label for office devices with printing function; RAL-UZ 171 – BAM July, 2012

** Based on ozone concentration when printing 2 hours per day in a 32 cubic meter room with a ventilation rate of 0.72 air changes per hour with HP printing supplies

Power consumption

Power usage drops significantly while in Sleep or Auto-Off mode, which saves natural resources and saves money without affecting the high performance of this product. Hewlett-Packard printing and imaging equipment marked with the ENERGY STAR qualified imaging products:

® logo is qualified to the U.S. Environmental Protection Agency's

ENERGY STAR specifications for imaging equipment. The following mark will appear on ENERGY STAR

Additional ENERGY STAR qualified imaging product model information is listed at: www.hp.com/go/energystar

Toner consumption

EconoMode uses less toner, which might extend the life of the toner cartridge. HP does not recommend the full-time use of EconoMode. If EconoMode is used full-time, the toner supply might outlast the mechanical parts in the toner cartridge. If print quality begins to degrade and is no longer acceptable, consider replacing the toner cartridge.

Paper use

This product’s manual duplex feature and N-up printing (multiple pages printed on one page) capability can reduce paper usage and the resulting demands on natural resources.

Plastics

Plastic parts over 25 grams are marked according to international standards that enhance the ability to identify plastics for recycling purposes at the end of the product’s life.

ENWW Environmental product stewardship program 151
