36 Product information ENWW

Service approach

Repair of the output device no rmally begins with a three-step process: 1 Isolate the problem to the major system (the host computer, the network or server, or the

finishing-device system).

2 Determine whether the problem is located in the output device, the print unit, or the copy/

scan unit. 3 Troubleshoot the problem by using the “Troubleshooting flowchart” on page 198. Repair is usually accomplished by an assembly-level replacement of field replaceable units

(FRUs). Some mechanical assemblies can be repaired at the subassembly level. HewlettPackard does not support replacement of components on the printed circuit assemblies.

Parts and supplies

“Consumables and documentation” on page 252 contains FRU and replacement part numbers, and contains information about products that are specifically designed for the output device. Replacement parts can be ordered from the HP Customer Support (HPCS) organization.

Exchange program

Hewlett-Packard might offer remanufactured assemblies for parts. These can be ordered through HPCS.

Warranty

For warranty information and requirements, see the user guide f or the printer.

38 Installation ENWW

Environmental requirements

The electrical and environmental specifications must be maintained to ens ure th e cor re ct operation of the output device. Consider the following points before installing the output device:

● Install in a well-ventilated, dust-free area.

● Install on a level, flat surface that can support the printer and output device size and weight.

● Ensure adequate power-supply circuitry (see table 2 on page 28).

● Install where temperature and humidity are stable, with no abrupt changes, and away from

water sources, heating vents, humidifiers, air conditioners , refrigerators, or other major

appliances (see table 3 on page 28).

● Install away from direct sunlight, areas that experience vibration, open flames, ammonia

fumes, ultrasonic heaters, and devices that emit a magnetic field. If the output device is

placed near a window, make sure the window has a curtain or blind to block direct sunlight.

● Maintain enough space around the output device for proper access and ventilation (see

“Physical requirements” on page 39).

54 Theory of operation ENWW

Power-on sequence

Multifunction finisher

The multifunction finisher performs an initialization procedure when it receives the Recovery Initialize signal. This signal is transmitted from the printer at power-on.

The power-on sequence consists of the following actions: 1 Moves slide: The booklet bin slide motor (M10) drives the slide to move from the standby

position. The slide returns to the standby position when the home position is detected.

2 Folding action: The staple-fold motor (M7) drives one cycle of folding action. 3 Moves swing guide vertically: The paddle motor (M2) drives the swing guide to move

vertically.

4 Rotates paddler: The paddle motor (M2) drives the paddle to complete one cycle of

rotation.

5 Moves stapler: The slide motor (M8) drives the stapler to move from the standby position.

The stapler returns to the standby position when detecting the home position.

6 Perfo rms alignment: The front aligning plate motor (M4) and the back aligning plate motor

(M5) drive the front and back aligning plates to perform one cycle of alignment.

7 Moves stack-feed roller vertically: The transfer motor (M1) reverses, causing the upper

stack-feed roller to move vertically.

8 Moves delivery tray vertically: The shift motor (M6) drives the stacker bin (bin 1) to move

from the home position. The stacker bin returns to the home position when it is detected by the full loading sensor (P124).

9 Rotates ejector mechanism: The delivery motor (M3) drives the delivery belt to complete

one cycle of rotation after the stack e r bin has descended approximately 25 mm (1 inch). The stacker bin then retu rns to the home position.

3,000-sheet stapler/stacker

When the 3,000-sheet stapler/stacker is turned on, or a door is opened or closed, the 3,000sheet stapler/stacker completes the initialization routines as follows:

● Initialization in parallel for the paper path, the accumulator, the stack-holder/tray, and the

carriage.

● When the accumulator initialization is complete, the flipper will initialize.

After a successful power-on sequence, the error light is green. If the power-on sequence is not successful, a jam condition or a hardware malfunction is indicated through the printer control panel, and the error light is amber.

3,000-sheet stacker

When the stacker is turned on, or a door is opened and closed, the stacker completes the initialization in parallel f or the paper path, the flipper, the offset module, and the tray.

ENWW Chapter 5 Theory of operation 55

8-bin mailbox

When the 8-bin mailbox is turned on, the flipper and eject assemblies receive the initialization command and start the rollers in an attempt to eject any paper in the path. Then the assemblies check the sensors. If the sensors detect media, they signal an initial jam.

If no jam exists, initialization for the flipper and eject assemblies is complete. This triggers the elevator initialization. The elevator initialization is the same for all of the operating modes, with the exception of the end of the initializat ion. The final position of the elevator head depends on the presence of paper and the operation mode.

Note At initialization, make sure that the encoders in the flipper and belt motors are connected. If no

transitions are detected, a critical error is indicated. This test is perf ormed only during initialization.

56 Theory of operation ENWW

Basic operation

Multifunction finisher

The multifunction finisher ejects paper fro m the printer either face-down or face-up. Operations such as job offset are performed when paper is ejected face-down. The booklet unit inside the multifunction finisher folds the paper stack before ejecting it. The controller PCA in the multifunction finisher controls the sequence of operations.

Simple stacking

Flipping action (face-down delivery):

● After the paper is reversed, the paper is pulled into the processing tray and ejected face-

down to the delivery tray.

Figure 19. Simple stacking (face-down delivery)

Face-up de livery:

● The paper is pulled into the processing tray and ejected face-up to the delivery tray.

Figure 20. Simple stacking (face-up delivery)

58 Theory of operation ENWW

Job offset

Job offset is accomplished by moving sheet by sheet forward or backward for sorting while transporting it to the stacker bin. The offset motor is connected to a crank system that moves offset carriage to the left and to the right. The offset position sensor detects the position of the offset module to position it left, right, or center. The offset exit sensor detects when the sheet has left the accumulator assembly and is correctly delivered to the output tray.

Note The offset specification is 20 mm (0.79 inch) between sets of sheets (10 mm, or 0.39 inch, per sid e).

Stapling

The multifunction finisher staples the specified number of sheets of paper. The staple position depends on the staple mode and paper size.

Figure 22. Staple positions

When the multifunction finisher is turned on, the finisher controller PCB drives the slide motor to return the stapler to the home position. The stapler moves toward the front of the stapler frame, and stops at the slide home-position sensor on the slide PCB. The slide motor is driven a specified number of pulses, and the stapler moves to rear standby position and enters the standby state when it reaches the back of the multifunction finisher.

Booklet-making

Paper-fold rollers and the paper-pushing plate fold paper in the multifunction finisher. When the rollers start to rotate, the paper-pushing plate pushes the paper stack into the gap between the paper-fold rollers. When the paper stack is fed approximately 10 mm (0.4 inch) by the rotation of the paper-fold rollers, the paper-pushing plate returns to the home position. The paper-fo ld rollers and booklet-delivery rollers deliver the paper stack to the booklet tray.

Half of each paper-fold roller is uncovered (the center and the left and right ends are covered). The upper paper-fold roller touches the lower paper-fold roller at the center and at both ends to feed a paper stack without creating creases. The covered portion of the upper paper-fold roller touches the covered portion of the lower paper-fold roller, allowing a paper stack to be folded while being fed.

3,000-sheet stapler/stacker

Main modules

The 3,000-sheet stapler/stacker consists of the following main modules:

● Face-up bin—This bin collects the documents face-up, with the printed information toward

the user. Finished documents are not routed to this bin, but the bin supports the sheets as they are flipped to the f ace- do wn bin. Th is face-up bin has a capacity of 125 sheets of medi a (75 g/m

, or 20 lb).

● Face-down (stacker) bin—Collated and stapled jobs are routed to the face-down (stacker)

bin. The bin has a capacity of 3,000 sheets (75 g/ m

, or 20 lb) of letter/A4 paper or 1,500

sheets (75 g/m

, or 20 lb) of ledger/A3 paper.

● Accumulator—The accumulator collects the sheets in the accumulator bed and registers a

whole job or copy. Additionally, the accumulator transports the job to the stapler module when a stapling option is selected, and can also offset print jobs. After finishing, the accumulator routes the print job to the face-down bin.

● Stack holder—The stack holder holds the sheets that are in the face-down bin.

● Flipper—The flipper module flips sheets of paper from a face-up position to a face-down

position. This function is necessary in order to accumulate the job correctly and to accommodate staples.

● Paper path—The paper-path module rout es the print job after the media leaves the flipper

module if the printed media is face-down. If the media is face-up, the print job is routed directly from the flipper module to the face-up bin.

● Stapler and carriage—This module is used to staple print jobs. The stapler is mounted in a

carriage that moves from side to side. The side-to-side motion accommodates stapling in various positions on the edge of the print job that is in the accumulator.

● Controller PCA—The controller PCA controls the entire unit. All stapler/stacker-module

cables are connected to the controller PCA.

● Power supply—This is the main power supply for the device. The power supply is universal,

which means that it can work with products that use from 110 Vac to 220 Vac.

ENWW Chapter 5 Theory of operation 63

Paper path and jam detection

● Paper input—The device receives media from the printer.

● Flipper—FLEntry1 senses the media and activates the flipper motors. For face-up printing,

the flipper delivers the media (which the FLEntry senses) to the face-up bin. Otherwise, the flipper changes page orientation from face-up to face-down and delivers media to the paperpath module.

● Paper path—The paper-path module delivers face-down print jobs to the accumulator

assembly. This module is bypassed if the destination is the face-up bin.

● Accumulator assembly—The accumulator assembly collects and registers print jobs from

the flipper (which the GWSens senses), sends them to the carriage assembly for stapling, and delivers them to the stapler bin (wh ich the ACExit senses).

Figure 28. Stapler/stacker jam detection

The paper-path sensors detect jams at the following locations:

● Flipper entry sensor 1 (FLEntry1) and flipper entry sensor (FLEntry)

Stapler/stacker bin full condition

The stapler bin signals a “full” condition when either of these conditions exist:

● Approximately 3,000 sheets of letter/A4 have been collected in the stapler bin

● Approximately 1,500 sheets of ledger/A3 have been collected in the stapler bin

Note A full-bin condition is signaled when the stapler bin contains 15 kg (33 lb) of paper.

Full bin—Optical sensors detect the presence of paper and the full-ministack condition. The stapler bin accepts paper until a full-ministack condition (up to 70 sheets of paper) is detected. The stapler bin then receives a signal to descend and then cont in u e accept ing paper. This cycle is repeated several times, until the stapler bin activates the full-bin microswitch that is located at the bottom of the unit. This microswitch indicates a full-bin condition when using letter/A4 or equivalent paper.

Overload—Optical sensors detect the presence of paper and the full-ministack condition. The stapler bin accepts paper until a full-ministack condition (up to 70 sheets of paper) is detected. The stapler bin then receives a signal to descend and then continue accepting paper. When using ledger/A3 or equivalent paper, the overload microswitch is activated when the full-bin condition exists and the weight of the paper stack reaches 15 kg (33 lb).

3,000-sheet stacker

Main modules

The stacker consists of the following main modules:

● Face-up bin—This bin collects the documents face-up, with the printed information toward

the user. Finished documents are not routed to this bin, but the bin supports sheets as they are flipped to the face-down bin. This face-up bin has a capacity of 125 sheets of media (75 g/m

, or 20 lb).

● Face-down (stack er) bin—Th e f ace-down bi n can collect print jobs with or without offset. The

bin has a capacity of 3,000 sheets (75 g/m

, or 20 lb) of letter paper or 1,500 sheets (75 g/

or 20 lb) of ledger paper.

● Offset module—The offset module offsets print requests on a job-by-job basis as the print

job is transported to the stacker bin.

● Flipper—The flipper module flips sheets of paper from a face-up position to a face-down

position. This function is necessary in order to route the jobs to the stacker bin correctly.

● Paper path—The paper-path module rout es the print job after the media leaves the flipper

module if the printed media is face-down. If the media is face-up, the print job is routed directly from the flipper module to the face-up bin.

● Controller PCA—The controller PCA controls the entire unit. All stacker-module cables are

connected to the controller PCA.

● Power supply—This is the main power supply for the device. The power supply is universal,

which means that it can work with products that use 110 Vac to 220 Vac.

the flipper delivers the media to the face-up bin. Otherwise, the flipper changes page orientation from face-up to face-down and delivers the media to the paper-path module.

● Paper path—The paper-path module deliv ers face-down print jobs to the offset module. This

module is bypassed if the destination is the face-up bin.

● Offset module —The offset module delivers face-down print jobs directly to the stacker bin

(which the Exit senses). Jobs are offset in accord with the print configuration.

Stacker-bin-full condition

The stapler bin signals a “full” condition when either of these conditions exist:

● Approximately 3,000 sheets of letter/A4 have been collected in the stapler bin

● Approximately 1,500 sheets of ledger/A3 have been collected in the stapler bin

Note A full-bin condition is signaled when the stapler bin contains 15 kg (33 lb) of paper.

8-bin mailbox

Main modules

The 8-bin mailbox has 9 bins for sorting and handling printed media. The topmost bin receives the media face-up as it comes from the printer. The remaining eight bins receive the media facedown. The destination bin for the printed media depends on the device operating mode and the presence of media. The top bin in this 8-bin group can be configured as a copier bin, and used exclusively for copies from an MFP.

The 8-bin mailbox has several subassemblies or mechanical parts that work together to perform the paper-handling function:

● Flipper—The flipper is the assembly at the 8-bin mailbox entry point. It receives the sheets

from the printer and then delivers them to the face-up bin or flips them for deliver to the facedown bins. The flipper has a moving input paper guide that latches into the printer or MFP exit to provide a continuous paper path.

● Belt—The transport belt system is a vertical mechanism that takes the sheets that the flipper

assembly flips and mov e s them d o wn to t he elevator head for delivery to the face-down bins. The system consists of a rubber belt and a flexible sheet-metal guide. The sheets are pressed between them for transport.

● Delivery head—The delivery-head mechanism is the most complex part in the 8-bin mailbox.

It positions the elevator head in front of the bin where a sheet is to be delivered. The eject system is included in the elev ator head. The eject syst em has tw o sensors in its path : one f or detecting a sheet that is arriving from the belt (EXIT1) and one for detecting a sheet that is about to be ejected (EXIT2). A single stepper motor drives the sheet for ejection. Another stepper , called th e slider, positions a group of rollers to feed into the bins. The rollers are not fixed, because th ey hi t the bins when t he head mo v es up or do wn. Inst ead, the y retr act when the head moves , and extend into the bins after the head stops. A single sensor indicates the position of the slider.

● Bins—The 8-bin mailbox has a total of 9 bins. The topmost bin holds media that is delivered

face-up, and the lower 8 accept face-down delivery. The bins have no moving parts, but the face-down bins use a system of slots and lever flags that the elevator reads to indicate where it is positioned, the bin capacity, the presence of media, and bin-full conditions. In order for the sensors to read valid information, the bins must be correctly placed. The operation of the delivery is especially sensitive to misplaced bins. Note that the lever flag for each bin is mounted in the bin directly above it.

● Controller PCA—The controller PCA or main board is attached to the bottom of the 8-bin

mailbox, with the internal wiring and harnesses routed vertically along the inside of back cover.

● Power supply—A univer sal power supply is activated when the printer or MFP power switch

is turned on. The printer or MFP paper-handling controller sends a power-on signal to the power supply on the 8-bin mailbox through the controller PCA. The power-supply circuit provides +24 V fo r motors an d +5 V for sensors and controller electronics. The pow er supp ly is also activated when the controller PCA is set to service mode.

Paper-path and jam detection

● Flipper—The flipper assembly receives the media from the printer or MFP. When it receives

a delivery notice from printer or MFP, the flipper motor starts to move at the print or copy speed. When the ENTR Y sensor is activated, the sheet is measured. If the sheet goes to the face-up bin, the FACEUP sensor is deactivated to signal the end of the paper-handling function and the sheet is ejected immediately. If the sheet goes to a f ace-do wn bin, the ent ry sensor is deactivated, which indicates t hat the motor sho uld stop and the n reverse to flip the sheet face-down. The flipper motor stops when the FACEUP sensor is deactivated in either case: when the sheet is flipped or when it is ejected to the face-up bin.

● Eject—On th e eje ct assembly, the belt starts moving whe n it receives a sheet-arriving

message. The belt then moves the sheet down to the elevator head and, when the sheet reaches the EXIT1 sensor, the eject motor starts. When the trailing edge of the sheet leaves sensor EXIT1, only the eject assemb ly handles the sh eet. The motor st ops immediately af ter the sheet is ejected, when the sheet is no longer touching the EXIT2 sensor. Note that the flipper ejects the sheet if the destination is the face-up bin.

● Elevator—The elevator assembly does not directly move paper. Instead, it places the

elevator head in front of the bins for paper delivery, as determined by the operating mode and the bin status.

The following illustration shows the paper path:

Bin-full condition

● Mailbox mode—The capacity status of each logical face-do wn bin depends on how the

sensor behaves in the face-down bin. A bin-full condition results from either of the following events:

• The bin-full sensor is activated when media is delivered to a face-down bin.

• The sensor determines that at least one face-down bi n is full after a bin scan is completed.

● Stacker mode—The 8-bin mailbox determines bin-full condition in either of the following

events:

• The top face-down bin fills.

• After a bin scan, the top scan is in the top face-do wn bin and it is full.

● Collator mode—A bin-full condition in the collator bin results from either of these events:

• The bin-full sensor is activated when media is delivered to a face-down bin.

• After a bin scan, a bin is determined to be full.

● Job separator mode—A bin-full condition in the job separation bin results from either of

these events:

• The bin-full sensor is activated when media is delivered to a face-down bin.

• After a bin scan, all the bins are determined to be full.

ENWW Chapter 5 Theory of operation 73

Electric circuitry

A 16-bit microprocessor is installed on the finisher controller PCB to control the finisher operation sequence and the Jet-Link communication with the video controller PCB.

The finisher controller PCB drives solenoids and motor s in res po ns e to the co mm a nd s th at the video controller PCB sends through the Jet-Link communication line . The fi nisher controller PCB also reports information about sensors and switches to the video controller PCB thr oug h the Je tLink communication line.

The following are important functions of the IC chips that are installed on the finisher controller PCB:

● IC21 (CPU): controls the operation sequence

● IC25 (EEP-ROM): backs up the adjustment values

● IC23 (flash memory): stores sequence programs

● IC1/IC4 (communication IC): communicates with the printer

Power supply

Multifunction finisher

The multifunction finisher power supply adopts a remote switching system. At power on, the printer issues a command to the video controller PCB. The video controller PCB then sends a power-on signal (PWRON-IN signal) to the power supply. When the PWRON-IN signal is at the high (“H”) level, the power-supply circuit supplies +24 V power and +5 V power to the finisher controller PCB. The +24 V power drives the feed motor, delivery motor, and solenoid. The +5 V power drives sensors, IC chips, and the finisher controller PCB.

Introduction

Removal and replacement strategy

This chapter documents the removal and replacement of field replaceable units (FRUs) only for the output devices.

Replace parts in the reverse order of th eir removal. Directions for difficult or critical replacement procedures are included.

WARNING! The sheet-metal edges of the output de vice can be sharp. Use caution when working on the output

device.

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

to its original location during reassembly. Incorrectly routed or loose wire harnesses can interfere with other internal components and can

become damaged or broken. Frayed or pinched harness wires can be difficult to locate. When replacing wire harnesses, always use the provided wire loops, lance points, or wire-harness guides.

Electrostatic discharge

CAUTION The output devices contain parts that are sensitive to electr ostatic discharge (ESD). Always service

the output device at an ESD-protected workstation, or use an ESD mat.

Watch for the ESD symbol (shown at left) to identify the parts that are sensitive to ESD. Protect these parts by using an ESD wrist strap and protective ESD pouches.

CAUTION A pozidriv screwdriver will damage screw heads on the output device. Use a #2 Phillips

screwdriver. If you use a multispeed screwdriver, use a torque limiter.

Required tools

The following tools are needed to service these ou tp ut devices:

● #2 Phillips screwdriver with a magnetic tip

● Small flatblade screwdriver

● Torx #20 screwdriver

● Torx #15 screwdriver

● Torx #10 screwdriver

● Small needle-nose pliers

● ESD mat

● Penlight
