Printer operation

Paper is held in a 150 page tray where it is picked by a center–fed D shape pick roller. The paper follows an L shape path as it moves through the printer. Images are created with toner on an optical photoconductor (OPC) drum within the toner cartridge. A transfer roller then draws the toner off the OPC drum onto the paper. Once the toner is affixed to the paper by the fuser, the paper exits either the top or front of the printer.

Printer dimensions and clearance

The following table contains the dimensions for each printer model. This does not include packaging but does include the print cartridge that ships with the printer.

Start

Diagnostics (E320/E322)

Note: For diagnostic information about models

E220/E321/E323 see “Diagnostics (E220/E321/E323) ” on

page 2-35 for more information.

CAUTION: NEVER manually actuate or disable the top cover

interlock switch and the printhead shutter actuator at the same time.

To perform some of the service checks and tests, such as troubleshooting paper feed problems, you need to actuate the top cover interlock switch with the covers open or removed and power applied to the machine. It is important for personal safety that you DO NOT, FOR ANY REASON, disable the printhead shutter actuator when power is on.

Unplug power from the printer before connecting or disconnecting any cable or electronic board or assembly for personal safety and to prevent damage to the printer.

Use the service error code, user error message, symptom table, service checks, and diagnostic aids in this chapter to determine the corrective action necessary to repair a malfunctioning printer.

The lights on the operator panel can indicate either a user error message or service error message. When a service error occurs, the printer stops printing and all operator panel lights blink in a continuous pattern, indicating a service error, until the printer is powered off. If all operator panel lights are blinking, go to the “Service error codes ” on page 2-11 for more information.

When a user error message occurs, one or more operator panel lights are on solid or blinking. See “Status information ” on page 2-3 for more information.

If the machine does not have a service error code and does not complete power–on self test (POST), go to the “POST symptom table ” on

page 2-32. If the machine completes POST without an error, and there is a

symptom, go to the “Printer symptom table ” on page 2-33. Locate the symptom and take the appropriate action.

Diagnostic information 2-1

4500–E320/E322

If a service error code appears while working on the machine, go to the “Service error codes ” on page 2-11 and take the appropriate action.

Operator panel

The E320/E322 operator panel consists of six indicator lights and one button. The information provided by the six lights is classified into three groups:

• Status

• Attendance

• Service

Depending on the light sequence, briefly (approximately one second) push the operator panel button to restart the printer, display an error code, or activate other printer functions.

The operator panel light table (see page 2-3) can be used to determine the type of message displayed based on which combination of lights are on or flashing.

2-2 Service Manual

4500–E320/E322

Status information

The following symbols are used in the status, attendance, and service information tables:

Operator panel lights

● Operator panel light is on.

❍ Operator panel light is off.

✳ Operator panel light is blinking.

Description

✕ Operator panel light is blinking

slowly.

Ready

The printer is in a Ready state.

Ready indicates the printer is ready to receive and process data from the host system.

• Brief button press executes a print test.

• Long button press executes a printer reset.

Diagnostic information 2-3

4500–E320/E322

Attendance information

When attendance information is displayed, the user is required to open the printer cover and clear all paper from the paper path. The user indicates the jam is cleared by closing the cover or by performing a brief button press.

Paper jam

A paper jam is detected.

• Brief button press assumes the jam has been cleared.

A warm–up is performed, and the print job resumes.

• Long button press is ignored.

• Open/close cover assumes the jam has been cleared.

A warm–up is performed, and the job prints.

2-4 Service Manual

4500–E320/E322

Host interface error

This error is generated when the printer detects an error communicating with the host computer. There are three causes of this error:

1. Parallel external network adapter (ENA) connection is lost during the printer’s power–on cycle. Once a connection is initially established, a printer setting is modified to note that the connection exists. Then, each time the power is cycled on the printer, if the setting states a connection exists, the printer attempts to communicate with the adapter. If the adapter does not respond, a message is posted.

This error is only detected during the power–on cycle. This means if the external network adapter connection is lost after the power–on cycle is complete, this error is not detected. The printer cannot distinguish between an adapter which is quiet, for example, not sending any data, and an adapter which has been disconnected.

Diagnostic information 2-5

4500–E320/E322

2. Standard parallel port disabled – this error is generated when the host computer attempts to communicate with the printer through the standard parallel port. However, the parallel port has been disabled either through the printer configuration mode, or through the MarkVision™ host utility

3. Standard USB port disabled – this error is generated when the host computer attempts to communicate with the printer through the standard USB port. However, the USB port has been disabled either through the printer configuration mode, or through the MarkVision host utility.

The error recovery process for this error is:

1. If this error occurs at power–on and an ENA is attached to the printer, verify the ENA is properly connected.

2. When the printer is in the Ready state, press the operator panel button to print a menus settings page.

3. Under the “parallel menu”, look for the “parallel buffer” line. If this line says “disabled” and the host computer is trying to print using the parallel port, re–enable the parallel port using MarkVision or the printers configuration mode.

4. Under the “USB menu”, look for the “USB buffer” line. If this line says “disabled” and the host computer is trying to print using the USB port, re–enable the USB port using MarkVision or the printer configuration mode.

See “Configuration mode ” on page 3-14 for information using the printer configuration mode to enable a disabled port.

2-6 Service Manual

4500–E320/E322

Service information

There are three levels of service code information.

• Primary service error codes

• Secondary service error codes

• Subcodes (sub set of the secondary codes)

Service information is displayed whenever the printer is in the check state, and needs servicing. In general, service errors are not recoverable. However, it may be possible to turn the printer off and back on to temporarily recover from the error condition if it is intermittent.

When a service error occurs, the printer stops printing immediately. The only recovery is to turn off the printer.

The following operator panel is an example indicating a primary service error code condition.

• Brief button press displays a service error code pattern.

• Long button press displays a service error code pattern.

• Double button press is not available.

• Open/close cover is ignored.

Diagnostic information 2-7

Cold fuser service check

Make sure the correct voltage lamp is installed. The voltage rating is stamped on one of the lamp contacts.

FRU Action

Fuser lamp Lamp cable LVPS Fuser

If the fuser lamp comes on and a fuser failure light error code displays, be sure the thermistor is contacting the hot roll and the thermistor cable is firmly seated in connector J7 on the engine board (E320/E322) or J14 on controller card (E220/E321/E323).

Check for excessive toner buildup on the surface of the thermistor. Clean as necessary.

With the printer unplugged, disconnect the thermistor cable from J7 (engine board in E320/E322) or J14 (controller card in E220/E321/E323).

Measure the resistance of the thermistor. The resistance measures approximately 1K ohms immediately after printing or POR to approximately 240K ohms when thermistor reaches room temperature. (It may take 30 minutes to cool.)

Replace the fuser assembly as necessary.

Service checks involve measuring voltages of the LVPS, high voltage power supply (HVPS), and controller card assembly. Continuity and resistance verifications are done on cables and components as required.

Note: When looking at the printed side of a PCB, connectors are

designated with “J” followed by a number. Pin 1 is designated on the PCB by an adjacent “1” or triangle. Pin numbers index sequentially to the opposite end of the connector. See “RIP

controller (E220/E321/E323 only) ” on page 5-8 for more

information.

Cooling fan service check (E220/E321/E323)

FRU Action

Cooling fan Make sure the cooling fan motor

cable plug is properly seated. Turn the printer off and disconnect

the cooling fan cable at J2 on the controller card.

Turn the printer on. Within a few seconds the controller card assembly should apply +24 V dc to pin #1. See “RIP controller (E220/

E321/E323 only) ” on page 5-8 for

more information.

• If voltage is present, replace the cooling fan first. If the fan still doesn’t function, replace the controller card.

Note: The fan speed is controlled by

a module on the PCB. Therefore, +24 V dc is constantly supplied at pin #1 (J2). Pin #2, the return, typically indicates varying voltages of less than +10 V dc in operation.

• If voltage is not present, see the

“RIP controller (E220/E321/ E323 only) ” on page 5-8 for

more information.

Controller card service check (E220/E321/E323)

FRU Action

Controller card assembly Verify +5 V dc and +24 V dc inputs

from the LVPS.

• Turn the printer off.

• Disconnect the LVPS cable from the controller card at J1. See

“Controller (E220/E321/E323 only) ” on page 5-7 for more

information.

• Turn the printer on.

Verify +24 V dc from the cable, pins 3 and 4. Verify +5 V dc on cable pin 1.

Verify that pins 2, 5 and 6 on both the cable and the card connectors are grounded.

• If voltages are correct, check the continuity in the cable. If the cable is good, see the “Low

voltage power supply (LVPS) service check ” on page 2-76

for more information.

• If grounds are not correct on the cable, first check it for continuity and then the LVPS.

• If the grounds are not correct on the controller card, replace the controller card. (Check with one probe on the connector pin and the other on the cards ground plane found at each screw head.)

FRU Action

Controller card assembly (continued)

Note: With all cables connected, the

printer should complete POST within approximately 12–15 seconds in the following sequence:

1. All operator panel lights on solid momentarily.

2. Lights then flash on and off sequentially.

After lights quit flashing, the Ready/Data light turns on solid.

3. The cooling fan comes on.

4. The fuser lamp comes on.

5. The drive motor runs.

6. The printhead motor runs.

7. The printer cycles down into standby mode/ready.

If immediately following power–on the operator panel lights are active but the printer does not go through steps 1 and 2 above, replace the controller card assembly.

Note: U.S. versus non–U.S. and the

printer configuration ID can be reset. See “Printer

diagnostics mode ” on page 3-40 for more

information.

If some lights are on or flashing, see “Status information light

patterns ” on page 2-38 to

determine a course of action.

Cover interlock switch Disconnect the cover interlock cable

plug from the engine board. Push the cover interlock switch to

the closed position and check for continuity. See “Connector

locations ” on page 5-1 for more

information. If the switch does not close, replace

the switch. Check for +24 V dc. If voltage is not

present, see “Engine board

service check (E320/E322) ” on page 2-72 for more information.

Cover interlock switch service check (E220/E321/E323)

Note: Make sure a toner cartridge is installed and the cover closes

all the way, engaging the cover open switch lever.

FRU Action

Cover interlock switch Disconnect the cover interlock cable

from the controller card at J6. Verify continuity between cable

pin 1 and pin 2 with the door closed. Verify continuity between cable

pin 1 and pin 3 with the door open.

• If either fail continuity, replace the cover interlock switch.

• If both pass continuity, turn the printer on and verify +5 V dc on pin 2 at J6 on the card.

• Verify pins1 and 3 are ground.

• If voltage or ground is not present, see “Controller card service

check (E220/E321/E323) ” on page 2-67 for more information.

Verify discontinuity between pins 2 and 3 whether the door is open or closed.

Replace the cover interlock switch if faulty.
