1. General information
The Lexm ark™ 4200 Series All-In-One (4413-XXX) is a letter quality
print, fax, copy, and scan machine. It is a standalone color/mono
copier and fax. The printhead uses small heater plates and nozzles
to control ink flow and the formation of characters on the print media.
The printhead assembly and ink supply are combined into a single
unit. Print cartridges are available as a customer replaceable supply
item. Dual printheads provide color and true black printing without
changing printheads. The number and size of inkjets or nozzles, in
the printhead, determines the overall quality and capability of the
printer. The black cartridge has a total of 208 nozzles and installs on
the right. The color cartridge has a total of 192 nozzles and installs
on the left. The printer is capable of printing in both directions from
either cartridge.

Maintenance station service check
The maintenance station has three functions:
1. Wipes the printhead nozzles to clean them of dirt.
2. Provides a place for printheads to fire all nozzles, keeping them
clear prior to printing.
3. Seals the printhead when it is not being used to prevent the
nozzles from drying.

Station Assembly
As the carrier moves to the right over the
maintenance station, a slot on the bottom of the
carrier engages a tab on the sled of the
maintenance station causing the cap to rise and
seal the printhead. Carrier movement to the left
uncaps the printhead. The wiper cleans the
printhead nozzles as the carrier leaves the
maintenance station. The wiper cleans the
printhead only when the carrier is moving to the
left. Do not wipe the printhead nozzles when the
carrier is moving to the right. After the cleaning
operation is complete, a tab on the maintenance
station engages a tab on the carrier, causing the
wiper to lower.
Check the maintenance station for worn or broken
parts. Replace if needed. G o to the “Maintenance
station removal” on page 4-17.

3. Diagnostic aids
Theory of mechanism
Scanner mechanism
The scanner mechanism consists of components which feed, scan,
and eject the documents that are to be copied or transmitted to a
remote facsimile unit. These components and their functions are
explained below.
Drive feed roller assembly
The drive feed roller assembly, consisting of various rollers, rubber
pad, and springs, automatically separates and feeds the pages of a
document over the scanning area and stacks them on the document
exit tray.
Documents up to 15 pages can be placed in the drive feed roller
assembly for scanning. The leading edge of the document moves
the document detect sensor lever when the operator slides the stack
into the drive feed roller assembly. The scan motor starts to rotate
when the document detect sensor detects the leading edge of the
document. The roller feeds the first page of the document into the
feeder.
The scan motor stops when the leading edge of the page actuates
the document scan sensor. The page is now in the scan position.
The drive feed roller assembly rubber pad prevents multiple sheets
from being fed. A spring provides force that the pad places on the
document pages for proper separation.
The scan motor is turned on when the machine is ready to scan the
document and drives the feed roller at a speed determined by the
resolution selected. The scan motor stops after a set period of time
when the trailing edge of the page releases the document scan
sensor. If another page is detected as the trailing edge of the page
releases the document scan sensor, the next page feeds to the scan
position. The exit roller pushes the page out onto the document exit
tray where it is stacked.
Diagnostic aids 3-1
4413-XXX
Contact Image Sensor (CIS)
The contact image sensor unit consist of LEDs, rod lens array , and a
photo sensor. The LEDs illuminate the document to be scanned
when the leading edge is detected by the document scan sensor.
The LEDs turn off when the document exits the scanner mechanism.
The LEDs illuminate the document to obtain an image from the
document through the rod lens array, where the image is translated
into voltage levels.
Document sensors
There are two document sensors in the scanner mechanism; the
document detect and the document scan sensor. The document
detect sensor, detects whether or not a document is loaded, and the
document scan sensor detects the scan position of the document.
The scanner mechanism consists of components which feed, scan,
and eject the documents that are to be copied or transmitted to a
remote facsimile unit.

4. Repair information
This chapter explains how to make adjustments to the printer and
how to remove defective parts.
Note: 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; 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 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 cold
weather heating is used because low humidity increases static
electricity.

Adjustments
The user is directed, in the Printer Control program, to perform the
bidirectional alignment adjustments after replacing a print cartridge.
Removal procedures
The following procedures are arranged according to the name of the
printer part discussed.
CAUTION: Unplug the power cord before removing any parts.
Releasing plastic latches
Many of the parts are held in place with plastic latches. The latches
break easily; release them carefully . To remove such parts, press the
hook end of the latch away from the part to which it is latched.
4-2 Service Manual

Removals
General precautions on removals
When you disassemble and reassemble components, use extreme
caution. The close proximity of cables to moving parts makes proper
routing a must. If components are removed or replaced, any cables
disturbed must be replaced as close as possible to their original
positions. Before removing any component from the machine, note
the cable routing.
When servicing the machine:
• Check to verify that documents are not stored in memory.
• Move the printer cartridge to far right to cap the nozzle.
• Unplug the power cord.
• Use a flat and clean surface.
• Replace only with authorized components.
• Do not force plastic-material components.
• Make sure all components are in their proper position.
