31 Defective Print
Cartridge Error code 31 is displayed when the top front
cover is closed and a defective print cartridge is
detected. It may take the printer 10-20 seconds to
determine if the print cartridge is defective.
Depending on the setting of the Machine Class ID
the printer may be allowed to print pages during
this 10-20 second interval. If pages are allowed to
print, they are not reprinted once a good print
cartridge is inserted.
Note: This error indicates the printer was able to
read the cartridge ID, but the ID did not pass the
verification test. To pass the verification test, the
ID read from the print cartridge must match the ID
from the last “good” print cartridge or the same ID
must be read from the print cartridge twice. The
last “good” print cartridge ID is stored in NVRAM.
32 Unsupported Print
Cartridge Error 32 is displayed when the top cover is closed
and an unsupported print cartridge is detected. It
may take the printer 10-20 seconds to determine
if the print cartridge is supported. Depending on
the setting of the Machine Class ID the printer
may be allowed to print pages during this 10-20
second interval. If pages are allowed to print, then
they are not reprinted once a good print cartridge
is inserted. If this does not fix the problem, go to
“Smart Cartridge Service Check” on page 2-105.
34 Short Paper The printer determines the paper length is too
short to print the formatted data. This occurs
when the printer does not know the actual paper
size loaded in the tray. For auto-size sensing
trays, this error occurs if the paper stop is in the
incorrect position. Make sure the Paper Size
setting is correct for the size paper that is being
used.

Print Quality - Banding
Service Tip: Banding is difficult to detect except on a page with a
uniform gray or a large amount of graphics printed on the page.
Banding is primarily due to a variation in the speed of the paper as it
feeds thru the printer, especially in the development and transfer
process. Inspect the alignment assembly, main drive assembly and
all other paper feed components for signs of wear, dirt, binds, or
damage, especially the drive gears. Banding appears as light or dark
horizontal lines on a uniformly gray page.
Banding can also be caused by a defective charge roll brush contact
or HVPS. Check the charge roll contact for any signs of damage and
for proper connection to the HVPS and print cartridge.

Autocompensator Operation
The autocompensator is a paper pick device that generates its own
normal force. This force generation is inherent in the fundamental
design of the pick arm. If light media is used, it picks very gently. If a
heavy media is used, it picks very aggressively. No customer
adjustments are necessary, therefore no special trays are needed for
card stock or labels.
The gearing in the arm is designed so the input torque from the
motor produces a movement about the pivot of the arm. This
movement produces a downward force at the pick rolls. The friction
between the pick roll and the paper produces a frictional locking
condition. If the paper is physically held and not allowed to feed, then
the motor stalls. Slippage between the roll and the paper is
theoretically impossible. When the motor is energized the pick rolls
are driven down into the stack increasing the normal force and drive
force until the bending strength of the paper is overcome and the
paper bends and moves up the dam. Once this critical threshold is
achieved the normal force remains at a level just high enough to
reliably feed the paper. Rather than having a fixed spring force for
Diagnostic Aids 3-27
4069-XXX
feeding all weights of paper like the D-roll, this device has its own
mechanical logic for producing only enough pick energy to feed a
single sheet of paper regardless of its stiffness.
High normal force is one of the most significant contributors to
double feeding paper. The pick arm is counter balanced by an
extension spring located on the pick arm to reduce weight in the rest
state. This spring is factory set to exert no more than ten to fifteen
grams on the stack. This is as light as can be realistically set and
always guarantee there is some force to start the autocompensating
phenomena. This spring is not to be considered an adjustment for
feeding problems unless it is obvious that the pick arm cannot fall all
the way down to the bottom of the tray or has come loose.
Poor gear efficiency can cause the arm to generate higher normal
forces. If the pick assembly is noisy, replacement may be required.
The arm must pivot freely through its full range of motion. On 500
sheet trays there are wrap springs located on the pivot arbors of the
arm. These springs aid to prevent the arm from bouncing. If the arm
appears to be binding or sticky near the bottom of the tray these
springs may be the problem. Reducing the tension on the
counterbalance spring may be used as a temporary fix to get
additional weight at bottom, until the pick assembly can be replaced.
However, the counterbalance spring is not to be considered an
adjustment for feeding problems.

Operations
Electrical
Autoconnect Cabling and Connectors
The printer options make electrical connection automatically or
autoconnects requiring no external cables when the option is
mechanically installed under the printer. Communication between
the option and the base printer stops when you remove an option
located above or below the printer. The printer no longer recognizes
the option and deletes associated messages. Each installed option
below the base printer provides an electrical autoconnect to the
3-28 Service Manual
4069-XXX
option attached below it. The output expander option attached above
the base printer provides power to the option above it. We do not
recommend to attach or “Hot Plug” any options with the base printer
power turned On.
Duplex Option
The duplex option interface is a six pin autoconnector that provides a
+24 V dc, +24 V dc return, serial interface transmit signal, serial
interface receive signal and two ground pins. The duplex option
receives the +24 V dc from the base printer for the duplex motors
and also converts the voltage to +5 V dc for duplex electronics.
Duplex chassis grounding is provided from the printer to the duplex
option through a ground spring attached to the frame and base of
the printer. The ground connection is automatically made when the
option is installed below the printer.
The paper input sensor is located in the rear of the duplex unit under
the input paper guide. The rear cover open switch is located on the
rear cover assembly. The paper exit sensor is located on the left
frame assembly. The jam removal tray open switch is located at the
end of the left frame assembly. There are no switches in the level 2
duplex option.
Option Microcode
The options are “Smart Options” or options that have a system
board. The option system board has a microprocessor that controls
the option mechanism. A software architecture is provided that
controls the option and communicates information such as paper
path status, sensor or switch status, motor status and so on to the
base printer.

Fuser Operation
Hot Roll Fuser
The hot roll fuser in the Optra T printer is made up of two primary
assemblies. The first assembly is the top fuser cover which contains
the thermistor/cable, thermal fuse, cable assembly, left and right
lamp brackets and cover. This is a complete assembly and the parts
cannot be individually replaced as in previous Lexmark laser
printers.
The thermal fuse (two fuses in series) protects the fuser assembly
and surrounding parts from ignition in the event of a failure in the
fuser control circuitry by opening the AC circuit to the lamp. The
thermistor assembly is designed to keep the temperature of the
fuser hot roll within a predetermined temperature by being in contact
with the fuser hot roll and changes resistance as the temperature of
the hot roll increases. The thermistor resistance changes from
approximately 150K ohms to approximately 260K ohms as the
temperature of the fuser hot roll increases. The thermistor is
connected to the fuser control board connector J2-1 and J2-2 and
from J2 to J1-2 and J1-3 on the fuser control board to J2-6 and J2-7
on the engine board. J2-6 (TEMPIN+) and J2-7 (TEMPIN-) are
connected to module PLCC U9. U9 monitors the change in
thermistor resistance and sends a signal (HEATON) from J20-A25
through the interconnect board to CN3-9 on the LVPS to signal the
triac to turn the fuser lamp On or Off to maintain the correct fuser
temperature.
The voltage drop across the thermistor is proportional to the fuser
temperature and varies from approximately 2.0 V dc (cold) to 2.3 V
dc (warm during idle) to approximately 2.7 V dc during continuous
printing. These voltages are assuming the fuser temperature is set
to normal. The HEATON signal from CN3-9 varies from 0 V dc (lamp
On) to +5 V dc (lamp Off) and is connected to the cathode of an
Opto triac to control the fuser lamp. The second part of the assembly
is the fuser frame which contains the hot roll, backup roll, and
associated parts as well as the paper exit guide assembly, narrow
media sensor, fuser control board (which has the exit sensor
mounted on the board) and the envelope conditioner solenoid.

WARNING: Read the following before handling electronic parts.
Handling 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
machine.
•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 machine.
•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 machine 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 ESD-
sensitive 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 cold-
weather heating is used because low humidity increases static
electricity.

6. Preventive Maintenance
This chapter describes procedures for printer preventive mainte-
nance. Following these recommendations can help prevent prob-
lems and maintain optimum performance.
Safety Inspection Guide
The purpose of this inspection guide is to aid you in identifying
unsafe conditions.
If any unsafe conditions exist, find out how serious the hazard could
be and if you can continue before you correct the hazard.
Check the following items:
•Damaged, missing, or altered parts, especially in the area of the
On/Off switch and the power supply
•Damaged, missing, or altered covers, especially in the area of
the top cover and the power supply cover
•Possible safety exposure from any non-Lexmark attachments
Lubrication Specifications
Lubricate only when parts are replaced or as needed, not on a
scheduled basis. Use of lubricants other than those specified can
cause premature failure. Some unauthorized lubricants may
chemically attack polycarbonate parts. Use IBM no. 10 oil,
P/N 1280443 (Approved equivalents: Mobil DTE27, Shell Tellus 100,
Fuchs Renolin MR30), IBM no. 23 grease (Approved equivalent
Shell Darina 1), and grease, P/N 99A0394 to lubricate appropriate
areas of the machine.
6-2 Service Manual
4069-XXX
Scheduled Maintenance
The operator panel displays the message “80 Scheduled
Maintenance” at each 300K page count interval. It is necessary to
replace the fuser assembly, transfer roller and charge roll at this
interval to maintain the print quality and reliability of the printer. The
parts are available as a maintenance kit with the following part
numbers:
99A1762 - 115V 875W Models 414/616/41b/41l/41e/41n/61n
99A1763 - 220V 875W Models 414/616/41b/41l/41e/41n/61n
99A1764 - 115V 550W Models 010/01n/212/21n
99A1765 - 220V 550W Models 010/01n/212/21n
After replacing the kit, the maintenance count must be reset to zero
to clear the “80 Scheduled Maintenance” message. Refer to
“Maintenance Page Count” on page 3-21.
