Circuit Description
Primary-charging-bias generation
Developing-bias generation
The primary charging bias negatively charges the surface of the photosensitive drum to prepare for image formation. The primary-charging-bias circuit in the high-voltage power supply generates the biases for each color.
The developing bias adheres toner to an electrostatic latent image formed on the photosensitive drum. The developing-bias circuit in the high-voltage power supply generates the biases for each color.
10 Chapter 1 Theory of operation ENWW
Table 1-7 High-voltage power supply circuits (continued)
Circuit Description
Primary-transfer-bias generation
Secondary-transfer-bias generation
The primary transfer bias transfers the toner from each photosensitive drum onto the ITB. The primary transfer bias circuit in the high-voltage power supply generates the biases for each color.
The secondary transfer bias transfers the toner image from the ITB onto the paper.
The secondary transfer bias circuit in the high-voltage power supply generates the bias. The reversed bias transfers residual toner on the secondary transfer roller back to the ITB. The residual toner on the ITB is deposited in the toner collection box.

Overcurrent/overvoltage protection
The low-voltage power supply stops supplying the DC voltage to the product components whenever it detects excessive current or abnormal voltage from the power source. 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 off and unplug the power cord. Do not turn the power switch on until the root cause is found. 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 circuit and the fuser control unit have a fuse to protect against overcurrent. If overcurrent flows into the AC line, the fuse blows to stop AC power.
Safety
For personal safety, the product interrupts 24 VB power to the fuser, high-voltage power supply, and motors, in addition to +5 VC to the laser scanners when the front or right door is opened. The power switch is on the dc line so that the ac power flows even if the power switch is turned off. Unplug the power cord before disassembling the product.
Voltage detection
The product detects the power supply voltage that is connected to the product. The DC controller monitors the POWER SUPPLY VOLTAGE (PSTYP100) signal and detects power supply voltage, whether 100 V or 200 V, to control the fuser operation.
Sleep (powersave) mode
Sleep mode conserves energy by stopping the power to several components when the product is idle.
If the DC controller detects voltage that is too high when the product is in Sleep mode, it determines that the low-voltage power supply has failed, and it notifies the formatter.
Low-voltage power supply failure
The DC controller determines a low-voltage power supply failure and notifies the formatter when the low-voltage power supply does not supply +24 V.

Fuser sleeve temperature protection
The fuser heater controls the temperature of the fuser sleeve. The DC controller detects the center area temperature by monitoring the main thermistor. The DC controller controls the FIXING HEATER
CONTROL (FSRD1) signal, so that the fuser sleeve remains at the targeted temperature.
● Protective function : The protective function detects rising temperatures in the fuser and interrupts power to the fuser heater. The following four protective components prevent the fuser sleeve and pressure roller from excessive rising temperature:
◦
DC controller
◦ Fuser heater safety circuit
ENWW Engine-control system 15
◦ Current detection circuit
◦
Thermoswitch
● DC controller : The DC controller monitors the detected temperature of the main thermistor and sub thermistors. The DC controller deactivates the FIXING HEATER CONTROL signal and releases the relay to interrupt power supply to the fuser heater under the following conditions:
◦
TH1: 230° C (446° F) or higher
◦ TH2: 285° C (545° F) or higher
◦
TH3: 285° C (545° F) or higher
● Fuser-heater safety circuit : The fuser heater safety circuit monitors the detected temperature of the sub thermistors. The fuser heater safety circuit releases the relay to interrupt power supply to the fuser heater under the following conditions:
◦
TH2: 290° C (554° F) or higher
◦ TH3: 290° C (554° F) or higher
●
Current-detection protection circuit : The current detection circuit monitors the current flowing through the fuser heater control circuit. The current detection circuit deactivates the fuser heater control circuit to interrupt power supply to the fuser heater when it detects the current higher than a specified value.
● Thermoswitch : If the temperature in the heaters is abnormally high, and the temperature in the thermoswitches exceeds a specified value, the contact to the thermoswitch breaks. Following are the thresholds for each thermoswitch:
◦
TP1: 270° C (518° F) or higher
NOTE: When the thermoswitches reach this temperature, the temperature on the fuser rollers is about
320° C (608° F).
Failure detection
The DC controller determines a fuser unit failure, deactivates the FIXING HEATER CONTROL signal, releases the relay to interrupt power supply to the fuser heater, and notifies the formatter of a failure status when it encounters any of following conditions:
● Abnormally high temperatures : Temperatures are too high for any of the following components, at any time:
◦
TH1: 230° C (446° F) or higher
◦ TH2: 285° C (545° F) or higher
◦
TH3: 285° C (545° F) or higher
● Abnormally low temperatures : Temperatures are too low at any of the following components after the product has initialized.
◦
TH1: 120° C (248° F) or lower
◦ TP2 or TP3: 100° C (212° F) or lower
●
Abnormal temperature rise : The DC controller determines an abnormal temperature rise if the detected temperature of TH1 does not rise 2° C within a specified time after the fuser motor is
16 Chapter 1 Theory of operation ENWW
turned on, or if the detected temperature of the thermistors does not rise to a specified temperature for a specified time after the fuser motor is turned on.
●
Thermistor open : The DC controller determines a thermistor open if:
◦ The detected temperature of TH1 is kept at 12° C (53° F) or lower for a specified time after the fuser motor is turned on.
◦
The detected temperature of TH2 is kept at 4° C (39° F) or lower for a specified time.
◦ The detected temperature of TH3 is kept at 4° C (39° F) or lower for a specified time.
●
Drive-circuit failure : The DC controller determines a drive-circuit failure:
◦ If the detected power supply frequency is out of a specified range when the product is turned on or during the standby period
◦
If the current detection circuit detects an out of specified current value
● Fuser discrepancy : The DC controller determines a fuser type mismatch when it detects an unexpected power supply voltage.
Fuser unit identification
The product detects the type and presence of the fuser. The DC controller detects whether the fuser is installed and its type by monitoring the FIXING UNIT IDENTIFICATION (FSRSNS) signal when the product is turned on or when the right door is closed. The DC controller determines a low-voltage power supply failure and notifies the formatter when it fails to detect the type or presence of the fuser.
NOTE: This product detects if the correct fuser for the product is installed. The fuser from a different product (for example, the HP Color LaserJet CP 3525 Series printer) can be installed in this product, but it will not correctly function.
Fuser unit life detection
The product detects the remaining life of a fuser. The DC controller recognizes a new fuser from the
NEW FIXING UNIT (/FSRNEW) signal. The DC controller determines a fuser's end of life and then notifies the formatter when a specified number of pages has been printed after the fuser was replaced.
NOTE: The product detects a new fuser using a fusible link that blows after 100 pages of printing. If a new fuser is installed for troubleshooting purposes, be sure to remove it before printing 100 pages.
ENWW Engine-control system 17
Laser/scanner system
The laser/scanner system forms the latent electrostatic image on the photosensitive drums according to the VIDEO signals sent from the formatter. The product has two laser/scanners: one for yellow and magenta and the other for cyan and black.
The main components of the laser/scanner system are the laser unit and the scanner motor unit, which are controlled by the signals sent from the DC controller.

Laser/scanner failure
The DC controller determines that a laser/scanner has failed when any of the following conditions occurs:
●
Laser failure : The detected laser intensity does not match a specified value when the product initializes.
●
Scanner motor startup failure : The scanner motor does not reach a specified rotation within a specified period from when the laser scanner starts driving.

Scanner-motor abnormal rotation : When a specified BD interval is not detected during a print operation, a BD error is determined. If the BD interval does not recover within a specified period after the BD error occurs, the product determines a scanner motor abnormal rotation.
The laser/scanner system does not have a mechanical laser shutter. For safety reason, the product has a interlock switch. The interlock switch is turned off to interrupt +5 V power supply to the laser/scanner system, when the front or right door is open.
Protective-glass cleaners
Each laser/scanner has two openings which allow the laser beam to pass to the surface of the photosensitive drum. These openings are covered by protective glass. When the protective glass gets dirty (for example, by paper dust or toner) a protective-glass cleaner (PGC) cleans them.
NOTE: When a glass is dirty, streaks appear on the printed page in the process direction.
The PGC is a cleaning pad which slides along the laser shutter. With the front door open, the laser shutter is positioned over the glass. As a print cartridge is inserted, the cleaning pad is pushed down and wipes the glass. When the front door is closed after cartridge insertion, the laser shutter (and PGC) move away from the glass which allows the laser beam to pass through the glass.
When the front door is opened, the laser shutter and PGC move back into position over the glass. When the cartridge is pulled out, the cleaning pad is returned to its starting position at the front of the cartridge opening.

Image-formation system
The image-formation system creates the printed image on the paper. The system consists of the following components:
● Print cartridges
●
ITB
● Secondary transfer roller
●
Fuser
● Laser /scanner units
The DC controller controls the laser scanner unit and each of the high-voltage power supplies to form the toner image on the photosensitive drum surface, according to the VIDEO signals. The toner image is then transferred to the print-media and fused.

Step 1: Pre-exposure
Light from the pre-exposure LED strikes the surface of the photosensitive drum to remove any residual electrical charges from the drum surface.
Figure 1-13 Pre-exposure
LED
Photosensitive drum
Step 2: Primary charging
The primary-charging roller contacts the photosensitive drum and charges the drum with negative potential.
Figure 1-14 Primary charging

24 Chapter 1 Theory of operation ENWW
Step 3: Laser-beam exposure
The laser beam strikes the surface of the photosensitive drum in the areas where the image will form.
The negative charge neutralizes in those areas, which are then ready to accept toner.
Figure 1-15 Laser-beam exposure
Laser beam
Step 4: Development
Toner acquires a negative charge as the developing cylinder contacts the developing blade. Because the negatively charged surface of the photosensitive drums have been neutralized where they have been struck by the laser beam, the toner adheres to those areas on the drums. The latent image becomes visible on the surface of each drum.
Figure 1-16 Development
Developing blade

ENWW Image-formation system 25
Step 5: Primary transfer
The positively charged primary-transfer rollers contact the ITB, giving the ITB a positive charge. The
ITB attracts the negatively charged toner from the surface of each photosensitive drum, and the complete toner image transfers onto the ITB.
Figure 1-17 Primary transfer
Primary transfer bias

Step 6: Secondary transfer
The paper acquires a positive charge from the secondary-transfer roller, and so it attracts the negatively charged toner from the surface of the ITB. The complete toner image transfers onto the paper.

Step 7: Separation
The stiffness of the paper causes it to separate from the ITB as the ITB bends. The static-charge eliminator removes excess charge from the paper to make sure that the toner fuses correctly.

The DC controller rotates the drum motor to drive the photosensitive drum, developing unit, and primary charging roller.
The memory tag is a non-volatile memory chip that stores information about the usage for the print cartridge. The product reads and writes the data in the memory tag.
Image-formation system 29
The DC controller determines a memory tag error and notifies the formatter when it fails to either read from or write to the memory tag.
●
Cartridge presence detection: The DC controller detects the presence of the cartridges by monitoring the memory tag. The DC controller notifies the formatter when a cartridge is missing or installed in the incorrect slot.
● Toner level detection: The DC controller detects the remaining toner in a cartridge by the optical detection method and then notifies the formatter of the remaining toner level.
●
Cartridge life detection: The DC controller detects the cartridge life by monitoring the total operating time or remaining toner level of the print cartridge. The DC controller determines a cartridge end of life and notifies the formatter when total operating time of the cartridge reaches a specified time or the cartridge runs out of toner.
Developing-roller engagement and disengagement
The product can print in full-color mode or in black-only mode. To print in black-only mode, the product disengages the developing rollers in the cyan, magenta, and yellow print cartridges which maximizes the life of the cartridges.

The developing-roller engagement and disengagement control operates as follows: When the product is turned on and when each print job is completed, all four of the developing units are disengaged from the photosensitive drums.
●
The drive of the developing disengagement motor rotates the developing disengagement cam.
● As the cam rotates, the developing unit engages with or separates from the photosensitive drum.
When the print mode is full color, the developing units engage with the drums. When the print mode is black-only, only the black developing units engages with the drum.
The DC controller determines a developing disengagement motor failure and notifies the formatter when it does not detect a specified signal from the developing disengagement sensor during the developing unit engagement and disengagement operation.
Intermediate transfer belt (ITB) unit
The ITB unit accepts the toner images from the photosensitive drums and transfers the completed image to the paper. The ITB unit has the following main components:
● ITB
●
ITB drive roller
● ITB-drive roller
● Primary-transfer roller
● ITB cleaner
The ITB motor drives the ITB drive roller, which rotates the ITB. The motion of the ITB causes the primary transfer rollers to rotate. The ITB cleaner cleans the ITB surface.

Primary-transfer-roller engagement and disengagement
The sequence of the primary-transfer-roller engagement and disengagement control is as follows:
1.
The fuser motor turns on the primary-transfer disengagement solenoid and rotates the primarytransfer-roller disengagement cam.
2.
As the cam rotates, the Y/M/C primary-transfer-roller slide plate or the Bk primary-transfer-roller slide plate moves to the right or left, which causes the primary-transfer roller to move up or down.
3.
The ITB engages with or separates from the photosensitive drum depending on the movement of the primary-transfer rollers.
Depending on the requirements of the print job, the primary-transfer rollers engage with the ITB so it can receive toner from the photosensitive drums. The primary-transfer roller has three engagement states.
Table 1-10 Primary-transfer-roller engagement states
All rollers disengaged The ITB is disengaged from all the four photosensitive drums. This state is the home position for the ITB unit.
All rollers engaged
Black roller engaged
The ITB is engaged with all four photosensitive drums. The state for full-color printing.
The ITB is engaged with only the black photosensitive drum. The state for blackcolor mode printing .
The DC controller determines a primary-transfer-roller disengagement failure and notifies the formatter when it does not detect a signal from the primary-transfer disengagement sensor even though the primary-transfer disengagement solenoid is turned on.
If the DC controller does not receive the expected signal from the ITB home-position sensor when the primary-transfer-roller engages or disengages, but the primary-transfer-roller disengagement motor is rotating, the DC controller determines that the primary-transfer-disengagement mechanism has failed, and notifies the formatter.
The DC controller detects whether the ITB unit is new by monitoring the new ITB unit sensor. The DC controller determines the ITB unit is at end of life and notifies the formatter when a specified number of pages are printed after the ITB unit is replaced. If swapping ITB units between two products for troubleshooting purposes, be sure to return the ITB units to their original products to maintain the correct life count.
NOTE: A new ITB has a flag that causes the ITB life counter to be reset. When an ITB is installed in the product, it cannot be removed and used again as a new ITB.
The DC controller detects the presence of an ITB unit by monitoring the primary-transfer-roller disengagement sensor. The DC controller turns on the primary-transfer disengagement solenoid for specified times during an initial rotation period when the following events occur:
● The product is turned on.
●
The product exits sleep mode.
● The door is closed.
The DC controller determines the absences of an ITB unit and notifies the formatter when it does not detect a specified signal from the new primary transfer-roller disengagement sensor.

ITB cleaning
The cleaning blade in the ITB cleaner scrapes the residual toner off the ITB surface. The residual toner feed screw deposits the residual toner to the residual toner feed unit. The ITB motor and the residual toner feed motor drive the screw. The DC control detects whether the toner collection box is full, using the residual-toner full sensor, and then notifies the formatter.

Calibration
The product calibrates itself to maintain excellent print quality. Calibration corrects color-misregistration and color-density variation.
During calibration, the product places a specific pattern of toner on the surface of the ITB. Sensors at the end of the ITB read the toner pattern to determine if adjustments are necessary.
NOTE: The product performs a drum-speed adjustment (DSA) during the full calibration operation.
The DSA compensates for variations between each drum and the speed of the ITB surface.
34 Chapter 1 Theory of operation ENWW
Color-misregistration control
Internal variations in the laser/scanners can cause the toner images to become misaligned. The colormisregistration control corrects the following problems:
● Horizontal scanning start position
●
Horizontal scanning magnification
● Vertical scanning start position
The DC controller forms a pattern of toner on the surface of the ITB and measures a misaligned length with the RD sensor.
Figure 1-28 Toner patterns for calibration
RD sensor ITB
Pattern of toner
The DC controller signals the formatter to perform the color-misregistration control when one of the following events occur:
● A cartridge or the ITB is replaced.
●
A specified number of pages have printed.
● The formatter sends a command.
The DC controller determines an RD sensor failure and notifies the formatter if it detects data from the
RD sensor that is not in a specified range, when the product is turned on or when the colormisregistration control starts.
Image-stabilization control
NOTE: The product contains a thermal sensor, located within the TCU level detection sensor, which monitors the temperature in the cartridge area and uses this information to make adjustments during
CPR control.
ENWW Image-formation system 35
Environmental changes or deterioration of the photosensitive drums and toner can cause variations in the image density. The image-stabilization control reduces these fluctuations.
Table 1-11 Image-stabilization controls
Image density control (DMAX) This control corrects variations in image density related to deterioration of the photosensitive drum or the toner. The DC controller adjusts the high-voltage biases to correct the problem under the following conditions:
Image halftone control (DHALF)
The image-stabilization control calibrates each high-voltage bias to stabilize the fluctuations in image density caused by deterioration of the photosensitive drums or toner or because of environmental changes. The DC controller determines the product's environment based on the surrounding temperature and humidity data from the environment sensor. The DC controller calibrates the biases according to the detected environment and usage condition of the print cartridge to obtain an appropriate image. The DC controller determines an environment sensor failure and notifies the formatter when it detects environmental data from the environment sensor with out of specified value. The DC controller commands the formatter to control the image density under the following conditions
● The temperature of the main thermistor is too low when the product is turned on.
●
A print cartridge or the ITB is replaced.
● A specified number of pages have printed.
●
After a specific period of the completion of a previous DMAX
●
The environment changes for a specified condition after a previous DMAX.
The formatter performs this control to calibrate the halftone, based on the halftonedensity measurements, under the following conditions:
●
The formatter sends a command.
●
DMAX is completed.
The DC controller determines an RD sensor failure and notifies the formatter if it detects data from the RD sensor out of a specified range.
The DC controller determines a RD sensor failure and notifies the formatter if it detects an out-ofspecified-data value from the RD sensor when the product is turned on or when the color misregistration control starts.

The operational sequence of the cassette lift-up is as follows:
1.
The lifter motor rotates and the lifter moves up.
2.
When the cassette-media stack surface sensor 2 detects the stack surface of media, the lifter motor stops.
3.
The lifter motor rotates again to lift the lifter when the cassette-media stack surface sensor 1 detects the stack surface and then lowers during printing.
When a cassette-media stack surface sensors does not detect the stack surface within a specified time period after the lifter motor starts rotating, the DC controller determines a lifter motor failure and notifies the formatter
Cassette multiple-feed prevention
In the cassette, a separation roller prevents multiple sheets of paper from entering the paper path. The cassette pickup roller drives the separation roller through a sheet of paper.
The rotation of the cassette feed roller through the sheet drives the cassette separation roller. Because it is equipped with a torque limiter, only one sheet is fed into the product.
ENWW Pickup, feed, and delivery system 43
The low friction force between the sheets weakens the driving force from the cassette feed roller.
Therefore, the separation roller is driven by its own driving force and holds back any multiple-fed sheets from the cassette.

3.
When the TOP sensor detects the leading edge of paper, the DC controller stops the paper so that the media sensor detects the type of paper.
4.
The DC controller controls the rotational speed of the pickup motor to align the paper with the leading edge of the toner image on the ITB.

Paper detection
The product detects the type of paper by monitoring the media sensor. The media sensor detects the glossiness of paper by the reflected light and the thickness of paper by transmitted light. The DC controller identifies the type of paper (for example, plain paper, light paper, heavy paper, glossy paper,
ENWW Pickup, feed, and delivery system 47
glossy film, or overhead transparency) and switches to the correct print mode. The DC controller determines a media mismatch error and notifies the formatter under the following condition:

●
The specified print mode is overhead transparency (OHT), but the media sensor detects another paper type.
● The specified print mode is not auto or OHT, but the media sensor detects OHT.

●
The media sensor detects OHT.
The DC controller flashes the media sensor during the initial rotation period under the following conditions:
●
The product is turned on
● The product exits Sleep mode
When the light intensity is not a specified value, the DC controller determines a media-sensor failure and notifies the formatter.

Fusing and delivery unit
The fusing and delivery unit fuses the toner onto the paper and delivers the printed page into the output bin. The following controls ensure optimum print quality:
48 Chapter 1 Theory of operation ENWW
The face-down tray media full sensor on the output bin detects whether the tray is full of printed pages.
The DC controller notifies the formatter when the sensor is on for a specified time.

Loop control
The loop control stabilizes the paper feed operation before the paper enters the fuser. If the pressure roller rotate slower than the secondary transfer roller, the paper loop increases and an image defect or paper crease occurs. If the pressure roller rotate faster than the secondary transfer roller, the paper loop decreases and a vertical scanning magnification failure occurs because the pressure roller pulls the paper.
To prevent these problems, loop sensor 1 and loop sensor 2 detect the paper loop before the paper enters the fuser. The DC controller adjusts the rotational speed of the fuser motor according to the output signals from the loop sensors and maintains the paper loop. Loop sensor 1 is for light media, and loop

Paper-feeder cassette lift operation
The paper feeder keeps the paper stack surface at the correct pickup position. The cassette lift operation occurs under the following conditions:
●
The product is turned on.
●
The cassette is inserted.
●
The paper stack surface of the cassette lowers.
The sequence occurs as follows:
1.
The PD lifter motor rotates and the lifter moves up.
2.
When the tray media-stack-surface sensor detects the stack surface of the paper, the PD lifter motor stops.
3.
The PD lifter motor rotates again to lift the lifter when the PD cassette media-stack-surface sensor detects the stack surface, and then lowers during printing.
If a tray media-stack-surface sensor does not detect a stack surface within a specified period after the
PD lifter motor starts rotating, the paper feeder driver determines that the PD lifter motor has failed and through the DC controller notifies the formatter.

Introduction
This chapter describes the removal and replacement of field-replaceable units (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 repairing individual subassemblies or troubleshooting to 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 find. When replacing wire harnesses, always use the provided wire loops, lance points, or wire-harness guides and retainers.
Removal and replacement strategy
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, in addition to damage to the product. The power must be on for certain functional checks during troubleshooting. However, disconnect the power supply during parts removal.
Never operate or service the product with the protective cover removed from the laser/scanner assembly. The reflected beam, although invisible, can damage your eyes.
The sheet-metal parts can have sharp edges. Be careful when handling sheet-metal parts.
CAUTION: Do not bend or fold the flat flexible cables (FFCs) during removal or installation. Also, do not straighten pre-folds in the FFCs. You must fully seat all FFCs in their connectors. Failure to fully seat an FFC into a connector can cause a short circuit in a PCA.
NOTE: To install a self-tapping screw, first turn it counterclockwise to align it with the existing thread pattern, and then carefully turn it clockwise to tighten. Do not overtighten. If a self-tapping screw-hole becomes stripped, repair the screw-hole or replace the affected assembly.
TIP: For clarity, some photos in this chapter show components removed that would not be removed to service the product. If necessary, remove the components listed at the beginning of a procedure before proceeding to service the product.

Verify that the cams (callout 1) align correctly.
TIP: The second cam in from the right (the white cam to the left of the black cam), should have the second hole aligned with the hole in the sheet-metal chassis.
The third cam in from the right, should have the third hole aligned with the hole in the sheet-metal chassis.
The fourth cam in from the right (the cam nearest the developing-disengagement motor), should have the fourth hole aligned with the hole in the sheet-metal chassis.
If the second, third, or fourth cams do not correctly align, do the following. Hold the long drive shaft, gently tilt the cam and gear away from the shaft to allow clearance to rotate the gear until the correct hole in the gear aligns with the hole in the chassis.

Power subsystem
Power-on checks
The basic product functions should start up when the product is plugged into an electrical outlet and the power switch is pushed to the on position. If the product does not start, use the information in this section to isolate and solve the problem.
Power-on troubleshooting overview
Turn on the product power. If the control panel display remains blank, random patterns display, or asterisks remain on the control panel display, perform power-on checks to find the cause of the problem.
During normal operation, the main cooling fan begins to spin briefly after the product power is turned on. Place your hand over the holes in the left-side cover, near the formatter. If the fan is operating, you will feel air passing out of the product. You can also lean close to the product and hear the fan operating.
You can also place your hand over the hole in the right-rear lower corner. If the fan is operating, you should feel air being drawn into the product. When this fan is operational, the DC side of the power supply is functioning correctly.
After the fan is operating, the main motor turns on (unless the right or front cover is open, a jam condition is sensed, or the paper-path sensors are damaged). You might be able to visually and audibly determine if the main motor is turned on.
If the fan and main motor are operating correctly, the next troubleshooting step is to isolate print engine, formatter, and control panel problems. Perform an engine test (see
Engine-test button on page 244
).
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, the control panel, or the cable that connects them.
If the control panel is blank when you turn on the product, check the following items.
1.
Make sure that the product is plugged directly into an active electrical outlet (not a power strip) that delivers the correct voltage.
2.
Make sure that the power switch is in the on position.
3.
Make sure that the fan runs briefly, which indicates that the power supply is operational.
4.
Make sure that the control panel display wire harness is connected.
5.
Make sure that the formatter is seated and operating correctly. Turn off the product and remove the formatter. Reinstall the formatter, and then verify that the heartbeat LED is flashing.
6.
Remove any HP Jetdirect or other EIO cards, and then try to turn the product on again.
NOTE: If the control panel display is blank, but the main cooling fan runs briefly after the product power is turned on, try printing an engine-test page to determine whether the problem is with the control-panel display, formatter, or other product components. See
Engine-test button on page 244 .
Power-on timing (approximate)
● 00.00 seconds; power-button LED illuminates
●
00.10 seconds; control panel backlight illuminates (dim) and engine noises begin
● 00:14 seconds; memory count appears on the control-panel display and fans rotate at high speed
240 Chapter 3 Solve problems ENWW
● 00:36 seconds; HP logo appears on the control-panel display
●
00:60 seconds; engine noises stop (you can run engine test at this point)
● 00:83 seconds; Initializing continues
●
00:85 fans rotate at slow speed
● 00:90 seconds; product enters the Ready state

Print/stop test
Use this diagnostic test to isolate the cause of problems such as image-formation defects and jams within the engine. During this test you can stop the paper anywhere along the product paper path. The test can be programmed to stop printing internal pages or an external print job when the paper reaches a certain position. The test can also be programmed to stop from 0 to 60,000 ms. If the timer is set to a value that is greater than the job-print time, you can recover the product in one of two ways.
●
After the print job is completed press Stop to return to the DIAGNOSTICS menu before the timer times out.
●
After the timer times out, press Stop . Activate the door switch to restart the engine and return it to a normal state.

Interpret control-panel messages
Control-panel message types
Four types of control-panel messages can indicate the status of or problems with the product.
Message type
Status messages
Warning messages
Error messages
Description
Status messages reflect the current state of the product. They inform you of normal product operation and require no interaction to clear them. They change as the state of the product changes. Whenever the product is ready, not busy, and has no pending warning messages, the status message Ready appears if the product is online.
Warning messages inform you of data and print errors. These messages typically alternate with the
Ready or status messages and remain until OK is pressed. Some warning messages are clearable.
If CLEARABLE WARNINGS is set to JOB on the product CONFIGURE DEVICE menu, the next print job clears these messages.
Error messages communicate that some action must be performed, such as adding paper or clearing a jam.
Some error messages are auto-continuable. If AUTO-CONTINUE is set on the menus, the product will continue normal operation after an auto-continuable error message appears for 10 seconds.
NOTE: Pressing any button during the 10-second auto-continuable error message overrides the auto-continue feature, and the button function takes precedence. For example, pressing the stop button pauses printing and offers the option to cancel the print job.
Critical-error messages Critical error messages inform you of a product failure. Some of these messages can be cleared by turning the product off and then on. These messages are not affected by the AUTO-CONTINUE setting. If a critical error persists, service is required.

Service mode functions
Service menu
The SERVICE menu is PIN-protected for added security. Only authorized service people have access to the SERVICE menu. When you select SERVICE from the list of menus, the product prompts you to enter an eight-digit PIN number. The PINs for the HP Color LaserJet Enterprise CP4020-CP4520 Series are 11402509 and 11452509.
1.
Press the Home button.
2.
Press the down arrow to highlight SERVICE , and then press the OK button.
3.
Enter the eight-digit PIN using the alphanumeric keypad.
4.
Press the OK button to enter the PIN and open the SERVICE menu.
The following menu items appear in the SERVICE menu:
CLEAR EVENT LOG
CLEAR BOOTLOADER PASSWORD
TOTAL PAGE COUNT
MONO CYCLE COUNT
COLOR CYCLE COUNT
This menu item allows you to clear the event log.
This menu item allows you to clear the bootloader password if it has been lost.
The page count stored in NVRAM and displayed on the configuration page represents the number of pages that the formatter has formatted (engine test prints are not included in this number). If it becomes necessary to repair a product by installing a DC controller PCA, you must set the page count so that it represents the age of the print engine rather than the age of the DC controller PCA. When you press either the up arrow
or down arrow to change the value of the first digit, the prompts are changed to indicate an acceptable range and the appropriate value.
After replacing the formatter, use this item to reset the mono page count so that the figure continues to represent the page count for the product engine. The page count that is stored in
NVRAM and printed on the configuration page represents the number of pages that the formatter has formatted (not including engine-test prints). If you install a new formatter when repairing a product, use this menu item to reset the page count to the previous value. In this way, the page count reflects the number of pages that the engine has printed rather than restarting the count for the new formatter. The page count is in two categories: total mono pages and total color pages.

422 Chapter 3 Solve problems
Use this item to show the date that the product was first used on the control panel. This eliminates the need for users to keep paper receipts for proof of warranty.
Restore the service ID
If you replace the formatter, the date is lost. Use this menu item to reset the date to the original date that the product was first used. The date format is YYDDD. Use the following formula to calculate the dates. The date 17-October-2002 is used as an example.
1.
To calculate YY, subtract 1990 from the calendar year.
For instance, if the product was first used in 2002, calculate YY as follows: 2002 - 1990 = 12. YY = 12.
2.
Subtract 1 from 10 (October is the tenth month of the year): 10 - 1 = 9.
◦
Multiply 9 by 30: 9 x 30 = 270 or add 17 to 270: 270
+ 17 = 287. Thus, DDD = 287.
Convert the service ID to an actual date
You can use the product Service ID number to determine whether the product is still under warranty. Use the following formula to convert the Service ID into the installation date as follows:
1.
Add 1990 to YY to get the actual year that the product was installed.
2.
Divide DDD by 30. If there is a remainder, add 1 to the result. This is the month.
3.
The remainder from the calculation in step 2 is the date.
Using the Service ID 12287 as an example, the date conversion is as follows:
1.
12 + 1990 = 2002, so the year is 2002.
2.
287 divided by 30 = 9 with a remainder of 17. Since there is a remainder, add 1 to 9 to get 10, which represents
October.
3.
The remainder in step 2 is 17, so that is the date.
4.
The complete date is 17-October-2002.
NOTE: A six-day grace period is built into the date system.
When you perform a cold reset, the paper size that is stored in
NVRAM is reset to the default factory setting. If you replace a formatter board in a country/region that uses A4 as the standard paper size, use this menu to reset the default paper size to A4. LETTER and A4 are the only available values.
Use after installing a new registration roller.
Use this menu item to calibrate the media sensor by selecting a threshold value from a specified range. This calibration is most likely to occur when a media sensor has been replaced, but might also occur if the current sensor needs to be optimized. The recommended media sensor threshold value for each sensor is included in the replacement kit for the part.

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 replacement 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. Doing so will ensure that the part number selected is for the correct all-in-one 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.

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.

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.
