WARNING!Po wer requirements are based on the region where the MFP is sold. Do not conv ert operating voltages.
This can damage the MFP and void the product warranty.
The electrical and environmental specifications must be maintained to ensur e the proper operation of
the MFP. Consider the following points before installing the MFP:
lInstall the MFP in a well-ventilated, dust-free area.
lInstall the MFP on a level, flat surface that can support its size and weight. Do not install on
carpet or on other soft surfaces. Make sure all four MFP feet are level.
lMake sure the power supp ly circui try is adequate. (See “Product specifications” on page 17.)
lInstall the MFP where temperature and humidity are st able, with no abrupt changes (away from
water sources, humidifiers, air conditioners, refrigerators, or other major appliances). (See
“Product specifications” on page 17.)
lInstall away from direct sunlight, areas that experience vibration, open flames, ammonia fumes,
ultrasonic heaters, and devices that emit a magnetic field. If the MFP is placed near a window,
make sure the window has a curtain or blind to block direct sunlight.
lMaintain enough space around the MFP for proper access and ventilation. (See “Space
requirements” on page 28.)

Product overview
Assembly identification
For service issues and section identification, the MFP has been separated into three sections.
lcopy/scan engine
lprint engine
lfinishing device
Copy/scan engine
Finishing device
Figure 2. Assembly identification
NoteA finishing device is required with the HP LaserJet 9000mfp.
For regulatory information and requirements , FCC regula tio ns, and declaration of confo rmity, please
see the start guide.
For environmental product stewardship program information, please see the use guide.
Service approach
Repair of the MFP normally begins with a three-step process:
1Isolate the problem to the major system (the host computer, the network and/or server, or the
MFP).
2Determine whether the problem is located in the print engine, the copy/scan engine, or the
finishing device.
3Troubleshoot the problem using “Malfunction troubleshooting” in chapter 7.
Once a faulty part is located, repair is usually accomplished by assembly-level replacement of field
replaceable units (FRUs). Some mechanical assemblies can be repaired at the subassembly level.
Hewlett-Packard does not support replacement of components on the printed circuit assemblies.
Parts and supplies
Information about ordering
“Ordering parts” in chapter 8 of this manual contains FRU and replacement part numbers.
Replacement parts can be ordered from the HP Customer Support (HPCS) organization.

Remote firmware upgrade
The process for upgr ading MFP firmware involves three steps:
1Determine the current level of firmware installed on the MFP.
2Go to the http://www.hp.com/go/lj9000_firmware website and download the latest firmware.
3See "Downloading the new firmware to the MFP" below to download the new firmware to the
MFP.
Downloading the new firmware to the MFP
You can send a remote firmware upgrade (RFU) to the MFP at any time. The MFP waits for all input/
output channels to become idle before turning power off and back on.
NoteIf the firmware upgrade involves a change in the format of NVRAM, the NVRAM settings will be lost
and must be reset again by the customer.
Microsoft® Windows® systems
NoteSome Windows systems might require the f ollowing command to be performed at the command prompt
if the system receives a “time out” error during the MFP firmware upgrade process:
“mode lpt1:,,p”
If the MFP is shared on a network, then the following command can be issued from a command
prompt:
copy /b FILENAME \\SHARENAME\PRINTERNAME
where FILENAME is the name of the RFU file, SHARENAME is the name of the computer from
which the MFP is being shared, and PRINTERNAME is the MFP share name.
If the MFP is connected locally, then the RFU file can be sent directly to the MFP with a copy
command from a command prompt or MS-DOS
copy /b FILENAME PORTNAME
where FILENAME is the name of the RFU file, and POR TNAME is th e nam e of the appr opriate print
engine port (such as LPT 1).
You can also send the file through an infrared receiver (IR) pod.
®
window:
UNIX® systems
Any method that delivers the RFU file to the MFP will work, including:
$ cp /home/yourmachine/FILENAME /dev/parallel
in which /home/yourmachine/FILENAME contains the RFU file.

Mechanical structure
The ADF optical assembly and the flatbed optical assembly both have a complete scanning system.
This enables single-pass duplex scanning of a document.
The scanner uses three dc stepping motors. Two of the stepping motors drive the ADF unit rollers,
and the other stepping motor drives the flatbed optical unit:
lThe flatbed motor rotates in one direction to drive t he flatbed optical unit when scanning is from
the glass. The flatbed motor ro tates in the opposit e direction to po sition the flatbe d optical unit f or
scanning from the ADF frontside.
lThe pickup motor r otates in one direction to rotate the pickup and feed rollers. The pickup motor
rotates in the opposite direction to rotate the registration rollers.
lThe delivery motor rotates the delivery rollers.
The three fans are for the ADF, the flatbed, and the power supply:
lThe ADF fan assembly includes a fan housing. The ADF fan is an intake fan.
NoteThe ADF fan can be ordered separately or with its plastic housing.
lThe flatbed fan assembly includes a filter. The flatbed fan is an intake fan.
NoteThe flatbed fan assembly filter only needs to be replaced when replacing the flatbed fan.
lThe power supply fan is an exhaust fan.

Basic block diagram
The CPB processes most jobs at the scan engine and sends the data to the print engine in the form
of hardware ready bits (HRB). The formatter performs three processing tasks: n-up, book copying,
and image rotation. When one of these tasks is performed, data is sent to the formatter in PCL-XL
format.
The formatter sends a scan command to the CPB after it rece ives a scan command from the contro l
panel by way of the dc controller. The CPB then sends a scan command to the scanner controller
board (SCB). The SCB generates th e imag e d ata and sends t he ima ge dat a ba ck to the CPB which,
in turn, passes the image back to the formatter. Depending on the original request from the control
panel (n-up, book copying, or image rotation), the formatter completes the processing. The data is
then passed to the dc controller for printing, or is passed to a computer for digital sending.

NoteWhen the control panel backlight is off , the +5V line is being signaled off at the control panel assemb ly
by the control panel controller board. SPON is the scanner power-on signal sent to the scan engine
power supply when the MFP is powered on by pressing the power switch on the print engine. See
“Low-voltage power supply circuit” on page 78 for more information.

To extend the life of the control panel backlight, the lamp is turned off when the HP LaserJet
9000mfp goes into sleep mode. If the sleep mode has been disabled (PowerSave is turned off), the
backlight will turn off after an hour of no activity.

Low-voltage power supply circuit
Opening the feeder co v er s witch cuts po wer t o the ADF scanning lamp, pickup motor, deliv ery motor ,
and the solenoids.
The power supply unit generates dc power required in the scan engine based on the ac voltage
supplied from the print engine power supply.
The remote switch is employed as a power switch of the scan engine. Of the voltages supplied from
the print engine dc controller to the power supply of the scan engine, 3.3 vdc are use d as a remote
signal. The signal is supplied to the power supply unit as the power remote signal (SPON) through
the intermediate circuit. When the signal is “H,” the low-voltage power supply cir cuit genera tes the ac
power to the dc power. The power generated in the circuit is converted to +24 vdc, +15 vdc, +5 vdc,
and +3.3 vdc required in the scan engine. The +24 vdc is supplied to the motors, solenoids, and
scanning lamps; +15 vdc to the sensors, LEDs, and ICs in the SCB; and +3.3 vdc to the CPB.
The +24 vdc is divided into the +24 vb and +24 va. The +24 va is constantly supplied from the lowvoltage power supply circuit, and the +24 va stops pow er supply when the feeder cover switch
(JMCSW) is turned off by opening the ADF feeder cover. The +24 va is supplied to the scanning
lamps, pickup mo tors, delivery motors, and solenoids. It also functions as the ADF FEEDER COVER OPEN DETECTION signal, and allows the CPU to detect an open cover.
Figure 45. Low-voltage power supply circuit
78 Chapter 5 Theory of operationC8523-90921
Page 79
Protective functions
The low-voltage power supply circuit utilizes overcurrent and overvoltage protective functions. The
protective functions automatically interrupt output voltage to prevent power supply failures. These
failures occur from an excessive current fl ow that is caused by a short circuit on the load side, or
from an abnormal voltage increase.
When the dc voltage is not output from the low-voltage power supply circuit, the overcurrent or
overvoltage protective function might be activated. If it is activated, turn off the printer, correct the
problem in the failu re loads , wait about two min utes , and then turn on the printer . The circuit contains
a power fuse (F1) which breaks and cuts off the po w er supply if overcurrent flows throug h the ac line .
Figure 46. Printer power supply
C8523-90921Basic system configuration 79
Page 80
Scanner controller circuit
The CPU on the SCB controls the operation sequences of the scan engine. When the dc power is
supplied to the scanner controller, the CPU starts to control the scan engine. When the scan engine
is in standby status, the CPU outp uts signals to drive each load of charge-coupled devices (CCDs),
motors, solenoids, and scanning lamps based on a scan command from the CPB.
lCPU (IC7): According to the control programs stored in the ROM (IC5), the CPU performs:
• image scanner sequence contr ol
• communication with the copy processor control
• pickup motor and delivery motor drives control
lGA (Gate Array) (IC4): According to commands from the CPU, the GA performs:
• scanning lamp drive control
• sensors, switches, an d LEDs contr ol
• solenoids control
• fan motors control
• flatbed document scanning motor control
lEEPROM (IC16): The EEPROM stores the specific bac kup adjustment data of the scanner, such
as the leading-edge registration adjustment values and horizontal registrat ion adjustment
values.
lROM (IC5): Stores the scanner control programs.
lPickup motor driver IC (IC3): Drives the pickup motor based on commands from the CPU.
lDelivery motor driver (IC1): Drives the delivery motor based on commands from the CPU.
lFlatbed document scanning motor driver IC (IC 9): Drives the flatbed scanning motor based
on commands from the GA.
lReset IC (IC17): Monitors +3.3V, and resets the CPU and GA when the power is turned on.

The SCB sends a signal (FBLAMP) to the flatbed inverter to turn on the scanning lamp. The flatbed
intermediate PCB and flatbed analog processor board pass on the signal. The flatbed inv erter sends
the signal to the scanning lamp and the document exposure process begins.

Flatbed optical drive control
The SCB sends a signal (CRMOT) to the flatbed motor to drive the flatbed optical unit forward to
scan from the glass, or backward when scanning from the ADF frontside.
HP-S is the flatbed home position detection sensor. When the flatbed optical unit is in the home
position, a signal (HP-S) is sent to the SCB.

Flatbed optical unit operation
The ADF optical unit is located 26.5 mm (1 inch) from the flatbed optical unit when the flat bed optical
unit is in the ADF scanning position.
When a two-sided original document is copied from the ADF, the first side begins copying bef or e t he
second side of the two-sided copy.
NoteThe mechanical lock on the HP LaserJet 9000mfp is not located in the “home position.” Locking the
carriage in the control panel moves the optical unit into position so the mechanical lock, which is located
on the left side of the unit, can hold the flatbed optical unit during a move.
To lock the carriage:
1Touch MENU
2Touch CONFIGURE DEVICE
3Touch RESETS
4Touch LOCK CARRIAGE
5Engage the mechanical lock
CAUTIONAlways engage the mechanical lock before moving the HP LaserJet 9000mfp to avoid damaging the
The sensors send signals to the SCB. The signals are transferred through the intermediate PCB to
the CPB. The CPB calculates the size of the document based on the signals from the sensors.
The flatbed document sensors are located in t he same positions on the 110 vdc and 220 vdc HP
LaserJet 9000mfp. To determine sizes of larger documents, the HP LaserJet 9000mfp searches the
Cold Reset Paper Size. For example, it will detect ledger if it is set to letter, and it will detect A3 if it is
set to A4.

Functions operation
When a document is placed on the glass and the ADF unit is closed or at an angle of less than 30
degrees, the SCB begins to detect the presence and size of the document. The SCB monitors
outputs from the flatbed document detection sensor (SCNSIZE1S) and the flatbed docu ment size
detection sensors (SCNSIZE2S, SCNSIZE3S, and SCNSIZE4S). The SCB passes the signals from
the sensors to the CPB.
The reflecting sensor detects the presence and size information of the document based on whether
the photoreceptor can receive the emitted light from the lumin ou s bo dy of the sens or. When a
document is on the glass, the document reflects the em itte d ligh t an d th e ph ot or ec ep to r ca n receive
the reflected light. When there is not a document on the glass, the emitted light passes through the
glass and the photoreceptor cannot receive the emitted light.

ADF angle detection
The SCB performs the detection by monitoring an output of the ADF angle detection sens or (PI-1).
The output of the PI-1 is “H” when the ADF unit is opened. When the angle between the glass and
the ADF is less than 30 degrees, the sensor lever interrupts the PI-1 and the ou tp ut of th e PI-1 is “L.”

ADF document exposure control
1The SCB sends a signal to the ADF inverter to turn on the scanning lamp.
2The ADF intermediate PCB and ADF analog processor board pass the signal through.
3The ADF inverter sends the signal to the scanning lamp and the document exposure process
begins.
NoteThe ADF inverter , ADF analog processor, and the ADF intermediate PCB are located inside the ADF.

ADF document feed control
ADF document feed control is performed to pass paper over the optical units for exposure. The ADF
document feed control process begins whe n the SCB sends signals. The shutter solenoid helps to
align the paper, and the weight plate “slaps” down on the stack of paper.
NoteBoth the shutter solenoid and the weight plate help to perform the pickup process.
The pickup motor drives the pickup rollers and the feed rollers, and then reverses rotation to drive
the registration rollers.
ADF document feed control terminology
lSTSOL: shutter solenoid
lPMOT: pickup motor
lWTSOL: weight solenoid
lDMOT: delivery motor

Pickup and feed operation
1The shutter solenoid is turned on when the SCB receives a scan command, and the document
shutters drop.
2About 200 milliseconds after the shutter solenoid is turned on, the pickup motor rotates in the
normal direction. The pickup roller, feed roller, and separation belts begin to rotate. At the same
time, the weight solenoid is turned on and the weight plate drops down. This allows the
document on the document tray to be sent to the feed roller by receiving the rotation drive from
the pickup roller and being pressed by the weight plate.
3The document sent to the feed roller is sent to the ADF feeder after any multiple feeds are
cleared by the feed roller and separation belts being driven by the pickup motor.
4The document sent to the ADF feeder passes through the registration document detection
sensor (REG-S) and reaches the registration roller. At this time the registration roller is not
rotating so that the leading edge of the document is pushed against the registration roller to
correct a skew.
5After a set period of time from when the leading edge of the document passes the REG-S, the
pickup motor rotates in its rev erse direction. This allows the registration roller to start rotating and
it re-feeds the document.
6When the leading edge of the re-fed document reach es the timing detecti on sensor (TMG-S), the
document scanning operation starts after a set period of time. The document set to the delivery
roller is sent out of the scan engine by the delivery motor rotating in the normal direction. The
delivery motor stops rotating after a set period of time.
7When the delivery motor stops, the shutter solenoid is turned off. The pickup operation is
complete after the pickup roller home position control operation.
Pickup roller home position control operation
The pickup roller home position control operation sets the pickup roller at its home position as an
advance preparation t o allow the roller to pick up the document .
1The SCB monitors the pickup home position detection sensor (PICK-S) to de tect the home
position.
2At the initial operation, or after delivering the document, the SCB rotates the pickup motor in the
revers e direction and checks a signal from the PICK-S.
3When the PICK-S detects the pickup home position lever on the shaft of the pickup roller, the
SCB determines that the pickup roller is at its home position and stops the pickup motor.
4When the SCB cannot detect the home position of the pickup roller within a specified period of
time after the pick up motor st arts rotating in the normal direction, the SCB recogniz es the pic kup
motor failure and notifi es the CPB. A 30.1.9 error is shown on the control panel.

ADF document size detection
The sensors and the potentiometer send signals to the SCB, and these signals are transferred
through the intermediate PCB to the CPB. The CPB calculates the size of the document based on
the signals in the service menu.

ADF document skew detection
1One of the skew sensors is activated.
2A signal is sent to the SCB.
3The SCB begins to read a certain number of clock pulses in 6 mm (.02 inch).
4A skew jam is not reported if the second skew sensor is activated before the allot ted number of
pulses.
NoteSkew detection is only performed when the document width is less than or equal to 257 mm (10.1
inches).

Scanned data flow
The HP LaserJet 9000mfp has a scan engine with 600 by 600 ppi (pixels per inch) resolution. It has
three channels (red, blue, and green) with 10 bits per channel, equalling a 30-bit scan engine.
Analog data is captured by the CCD drive r circuit and converted to digital data on the analog
processor board. Digital data is then sent through the three channels to the CPB. The CPB coverts
the digital data into one of the three final output types:
lHRB (hardware ready bits): most copy jobs are processed at the CPB and sent to the print
engine as HRB.
lPCL-XL: if rotation, book cop ying, or n-up is chosen in the job, th e CPB passes PCL-XL data to
the print engine and the formatter finishes the processing.
lJPEG (lossless): compresses image data from the CPB to the formatter when processing a
digital send job. The formatter then processes the data into the desired file type (TIFF, MTIFF,
JPEG, or PDF).

Copy processor board
The CPB is the link between the formatter in the print engine and the SCB in the scan engine.
Control signals from the formatter are sent to the CPB. The CPB sends these control signals to the
SCB. After the scanning process is completed b y the SCB , the scanned d ata is se nt to th e CPB . The
CPB processes the image and sends the image data to the formatter.

Scanning process control signals
The CPB controls the following scanning process control signals:
lADF unit and flatbed unit operation directs the SCB about the following:
• when to scan
• how to scan
• when to activate motors
• when to turn the scanning lamps on and off
lImage processing
• color alignment
• resolution conversion

• moire removal
• image scaling
• shifting of data strips (reconstructing separately processed image data before CPB
communication to the formatter)
• RGB conversion for CPB comm unication
• CPB communication to the formatter using one of the following formats:
•HRB (fastpath) communication with the hard drive on the formatter
•PCL-XL (n-up, rotation, book mode) communication with the hard drive on the formatter
•JPEG compression (when digitally sending data) communication with the hard drive on the
formatter
• data compression before sending to th e formatter over the high speed copy connect cable
Typical scanning process flow
1The original document is placed on the glass or in the ADF.
2The user enters job preferences using the control panel keys. The user presses the START key.
Job preferences are sent to the formatter.
3Some job preferences, such as n-up, will be held and processed later by the formatter. Others
are sent to the CPB.
4The CPB sends control signals to the SCB. The document is scanned.
5The SCB sends scanned image data back to the CPB.
6The CPB processes the image.
7The CPB sends the image data to the formatter.
8The formatter further processes the image data (if required).
9The image data is then either printed or digitally sent depending on what the user specified at the
beginning of the process.

Copy processor board LEDs
The CPB has four light-emitting diodes (LEDs) (callout 1) located at the back of the MFP. These
LEDs illuminate in specific patterns depending on the status of the CPB. The table in this section
details what occurs at each stage of CPB initialization.
HintThe LEDs can be difficult to see through the holes in the CPB facep late in a high-light e nvironment . It
may be necessary to turn off some lights or remove the faceplate to properly troubleshoot the LEDs.
The LED patterns displayed by the HP LaserJet 9000mfp are opposite those displayed by the HP
LaserJet 4100/4101mfp because the CPBs are mounted differently.
