Tips on preventing jams
You can avoid most paper jams by correctly loading paper and specialty
media.
The following hints can help you avoid paper jams:
•Do not load wrinkled, creased, or damp paper.
•Never mix media types within a tray.
•Flex, fan, and straighten paper before you load it.
•Do not exceed the maximum stack height.
•Push all trays firmly into the printer after loading them.
•Make sure the guides in the trays are positioned snugly against the
paper or specialty media.
•Do not remove paper trays while a job is printing. Wait for a Load Paper
or Ready light sequence or message before you remove the tray.
•Before loading transparencies, fan the stack to prevent sheets from
sticking together.
•Do not use envelopes that:
– Have excessive curl
– Are stuck together
– Are damaged in any way
– Contain windows, holes, perforations, cutouts, or embossing
– Have metal clasps, string ties, or metal folding bars
– Have postage stamps attached
– Have any exposed adhesive when the flap is in the sealed position
•Use only recommended paper. Refer to the Card Stock & Label Guide
available on the Lexmark Web site at www.lexmark.com for more
information about which paper provides optimum results for the current
printing environment.
Tools
The removal and adjustment procedures require the following tools and
equipment:
•Magnetic tip Phillips screwdrivers, large and small
•Volt-ohmmeter

Power-On Self Test (POST) sequence
When you turn the printer on, it performs a POST. Check for correct POST
functioning of the base printer by observing the following process:
1. All operator panel lights on momentarily
2. Lights then flash on and off sequentially.
3. After the lights quit flashing, the light flashes until the fuser comes
up to temperature (5–20 additional seconds, depending on the initial
temperature of the fuser) and then stays on.
4. If there is a problem in the printer such as a paper jam, the panel lights
indicate the problem. See “Common primary light patterns” on
page 2-4 for more information.
5. The printer cycles down into standby mode, and lights solid.
Diagnostics—E238, E240, and E240n 2-3
Light patterns and error messages
User attendance messages, paper jam errors, and service errors display a
light pattern. This may be all the information you need. However, if you
double-click on the panel, a second pattern may appear with more
detailed information. If you double-click a third time, you usually return to
the first pattern. Not all initial level light patterns have secondary patterns;
when you double-click, the pattern does not change.
All service errors are indicated by all lights flashing as the primary
notification or code. The secondary code indicates an area or function which
has the error. Additional tertiary codes used for service (see “Service
tertiary error codes” on page 2-40) indicate specific errors. See “Service
codes” on page 2-36.
Note: If you send data to the printer and all lights flash immediately, and
double-clicking does not change the display, there may be a code
problem. Contact the next level of support.

4. Repair information
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 cards:
•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 MFP 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.
