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.

2. Diagnostic information
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.

2-4 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.

The lights on the operator panel indicate the status of the printer
anytime it is powered on. When the printer experiences a problem
requiring operator intervention, it indicates the source by blinking
one or more lights. See “Status information light patterns ” on
page 2-38 for more information. When all six lights blink
simultaneously, a service may need to be performed. See “Service
error codes ” on page 2-45 for more information.
If the printer does not indicate a service error code nor complete
POST without an error but there is a symptom, see “Symptom
tables ” on page 2-60 for more information.

Cooling fan
Make sure the cooling fan motor
cable plug is properly seated on the
engine board.
Unplug the printer and disconnect
the cooling fan cable on the engine
board.
Restore printer power. Within
approximately 3 seconds the engine
board should apply +24 Volts direct
current (V dc) to the fan. See
“Connector locations ” on

• If voltage is present, replace the
cooling fan.
• If voltage is not present, see the
“Engine board service check
(E320/E322) ” on page 2-72 for
more information.
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

Diagnostic aids (320/E322)
This chapter describes procedures you can use to identify printer
failures and verify that repairs have corrected the problem.
Performing self test
At power–up, each light turns on and off in reverse sequence,
starting with Press Button and ending with Ready. Each light
remains on for approximately one second, but no more than
approximately two seconds. This cycling repeats as needed during
the execution of the self test. The printer performs the cycle at least
once. Additional cycles can be interrupted at any point in the cycle
indicating the self test is complete.
Information priority
The priority for displaying information on the operator panel is:
1. Service information
2. Top cover open
3. All other information in the order of occurrence

Diagnostic tests mode
The diagnostic tests mode causes the printers internal tests to be
performed. If any of the diagnostic tests fail, a service indication is
posted. You can determine which test failed by accessing the
service code associated with the service error. The secondary
service code is displayed by performing a button press while the
service indication is posted on the operator panel.
If the printer completes all its diagnostic tests successfully, the Toner
Low light blinks. To exit diagnostics, turn off the printer.
While running diagnostics, the printer performs the following tests:
• Standard memory test
• Optional memory test
When the printer enters Normal or Demo modes, the total amount of
installed memory detected during the POST sequence is compared
with an NVRAM value representing the printer total installed
memory.
• If the amount of detected memory matches the value stored in
•
NVRAM, the printer doesn’t perform a Memory Test during
POST sequence into Normal or Demo modes.
If the amount of detected memory does not match the NVRAM
value representing total installed memory, the printer assumes
the user has changed the printers memory configuration by
adding or removing optional memory.
To verify the new memory configuration, the printer performs a full
Memory Test and then updates the NVRAM value representing the
total installed memory.
Note: The printer always performs a complete Memory Test when
executing the Diagnostics Test.

Printer diagnostics mode
The printer diagnostics mode is for service use only. Its manipulation
is the same as the configuration mode. The following functions can
be performed in the diagnostics mode. See “Configuration menu
group or diagnostic menu group” on page 3-36 for more
information.
1. Print diagnostic instructions and menu settings by pressing and
holding Continue until the lights cycle.
We recommend this sheet be run and checked anytime
diagnostics mode is entered. It provides instructions in the
manipulation of the menu.
2. Set edge–to–edge printing on/off.
– Off is the default and normal setting which allows the printer
graphics and printing engine to set the margins accordingly.
– When edge–to–edge is set on, the printer graphic and
printing engine shift all four margins to the physical edges of
the paper.
3. Print the print quality pages.
– These are the same pages that are run in the configuration
mode.
Note: The toner cartridge lockout function is disabled in this
mode.
– In the configuration mode, the lockout function is enabled
which means the pages cannot be printed unless the toner
cartridge has a machine class ID that matches the machine
class ID held in NVRAM on the operator panel card.
4. Print simplex from Tray 1, or Tray 2 (if installed). This sheet runs
continuously until Cancel is pressed. It can be used for skew or
printhead adjustments.
5. ‘Defaults=’ allows the printer to be set for U.S. or non–U.S. after
the controller card has been replaced.
6. Configuration ID allows the printer to have the ID set to match
the label after the controller card has been replaced.
3-40 Service Manual
4500–E220/E321/E323
7. Par S strobe adjustment for the parallel port can be set to
four additional settings in addition to the default setting.
Pull–up resistors are only enabled indicating parallel mode 1 is
not supported. (Parallel mode 2 is supported and can be turned
off or on in the configuration mode.) Adjustments may have to
be made if an unusually long parallel cable is being used.
8. Network settings for mark history, history mode, Optra Forms™
mode, and meditech mode can be set.
– A service error history report (network) can be printed.
– Dump NVRAM prints a hex dump of the NVRAM partition
and the re–init NVRAM resets the network NVRAM to the
factory defaults.
Note: When a controller card is changed in a network printer,
print the menu and network sheets. (After POR, press
Continue.) If the “Printer Type” under “Integrated
Network Option Settings” does not match the “Name”
under “Appletalk”, go into the printer diagnostics mode
and reinitialize NVRAM (“Reinit NVRAM”). Verify that the
names match after reprinting the network sheet.

4. Repair information
Warning: Read the following before handling electronic parts.
Handling electrostatic discharge (ESD)sensitive parts
Many electronic products use parts that are known to be sensitive to
electrostatic discharge (ESD). To prevent damage to ESD-sensitive
parts, follow the instructions below in addition to all the usual
precautions, such as turning off power before removing logic boards:
•
•
•
•
•
•
•
•
•
Keep the ESD-sensitive part in its original shipping container (a
special “ESD bag”) until you are ready to install the part into the
printer.
Make the least-possible movements with your body to prevent an
increase of static electricity from clothing fibers, carpets, and
furniture.
Put the ESD wrist strap on your wrist. Connect the wrist band to
the system ground point. This discharges any static electricity in
your body to the printer.
Hold the ESD-sensitive part by its edge connector shroud
(cover); do not touch its pins. If you are removing a pluggable
module, use the correct tool.
Do not place the ESD-sensitive part on the printer cover or on a
metal table; if you need to put down the ESD-sensitive part for
any reason, first put it into its special bag.
Machine covers and metal tables are electrical grounds. They
increase the risk of damage because they make a discharge path
from your body through the ESD-sensitive part. (Large metal
objects can be discharge paths without being grounded.)
Prevent ESD-sensitive parts from being accidentally touched by
other personnel. Install machine covers when you are not
working on the machine, and do not put unprotected ESDsensitive parts on a table.
If possible, keep all ESD-sensitive parts in a grounded metal
cabinet (case).
Be extra careful in working with ESD-sensitive parts when coldweather heating is used because low humidity increases static
electricity.

Adjustment
Printhead assembly
The printhead may need to be adjusted after it has been reinstalled.
Tighten the four screws just enough to still move the printhead
frame.
Note: Always check the printhead alignment after replacing the
operator panel assembly. Settings on the original card may
not be the same as on the new operator panel card. Only a
skew adjustment can be made; margins cannot be adjusted.
Contact the next level of support or call Lexmark
(800) 539–6275 for assistance with margins.
To perform the registration check and adjustment:
1. Open the front door.
2. Press and hold Cancel while turning the printer on.
3. Hold Cancel until the lights have cycled on and off.
4. Close the door when the Error light comes on. Wait for the four
top lights to stay on.
5. Press and release Cancel once and wait for Ready/Data to
come on.
6. Press and release Cancel again and wait for Toner Low light.
7. Press and release Cancel again and wait for both Ready/Data
and Toner Low lights.
8. Press and hold Continue until lights cycle.
9. Once the printer starts to print, press Cancel or the same sheet
prints continuously.
Check margins and skew (top or bottom lines relative to edge of
paper). See Note above.
10. Adjust the printhead as necessary.
This adjustment can only correct for skew. Adjust the left side of
the printhead until the top (or bottom) line is parallel to the paper
edge.
11. After obtaining a proper adjustment, tighten all four screws.
