Laser notice
The printer is certified in the U.S. to conform to the requirements of DHHS
21 CFR Subchapter J for Class I (1) laser products, and elsewhere is
certified as a Class I laser product conforming to the requirements of IEC
60825-1.
Class I laser products are not considered to be hazardous. The printer
contains internally a Class IIIb (3b) laser that is nominally a 5 milliwatt
gallium arsenide laser operating in the wavelength region of 770-795
nanometers. The laser system and printer are designed so there is never
any human access to laser radiation above a Class I level during normal
operation, user maintenance, or prescribed service condition.
Laser
Der Drucker erfüllt gemäß amtlicher Bestätigung der USA die
Anforderungen der Bestimmung DHHS (Department of Health and Human
Services) 21 CFR Teil J für Laserprodukte der Klasse I (1). In anderen
Ländern gilt der Drucker als Laserprodukt der Klasse I, der die
Anforderungen der IEC (International Electrotechnical Commission) 608251 gemäß amtlicher Bestätigung erfüllt.
Laserprodukte der Klasse I gelten als unschädlich. Im Inneren des Druckers
befindet sich ein Laser der Klasse IIIb (3b), bei dem es sich um einen
Galliumarsenlaser mit 5 Milliwatt handelt, der Wellen der Länge 770-795
Nanometer ausstrahlt. Das Lasersystem und der Drucker sind so konzipiert,
daß im Normalbetrieb, bei der Wartung durch den Benutzer oder bei
ordnungsgemäßer Wartung durch den Kundendienst Laserbestrahlung, die
die Klasse I übersteigen würde, Menschen keinesfalls erreicht.

Laserinformatie
De printer voldoet aan de eisen die gesteld worden aan een laserprodukt
van klasse I. Voor de Verenigde Staten zijn deze eisen vastgelegd in DHHS
21 CFR Subchapter J, voor andere landen in IEC 60825-1.
Laserprodukten van klasse I worden niet als ongevaarlijk aangemerkt. De
printer is voorzien van een laser van klasse IIIb (3b), dat wil zeggen een
gallium arsenide-laser van 5 milliwatt met een golflengte van 770-795
nanometer. Het lasergedeelte en de printer zijn zo ontworpen dat bij
normaal gebruik, bij onderhoud of reparatie conform de voorschriften, nooit
blootstelling mogelijk is aan laserstraling boven een niveau zoals
voorgeschreven is voor klasse 1.
Lasermeddelelse
Printeren er godkendt som et Klasse I-laserprodukt, i overenstemmelse
med kravene i IEC 60825-1.
Klasse I-laserprodukter betragtes ikke som farlige. Printeren indeholder
internt en Klasse IIIB (3b)-laser, der nominelt er en 5 milliwatt
galliumarsenid laser, som arbejder på bølgelængdeområdet 770-795
nanometer. Lasersystemet og printeren er udformet således, at mennesker
aldrig udsættes for en laserstråling over Klasse I-niveau ved normal drift,
brugervedligeholdelse eller obligatoriske servicebetingelser.

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

2. Diagnostic information
Start
CAUTION: Unplug power from the printer before connecting or
disconnecting any cable, assembly, or electronic card. This is a
precaution for personal safety and to prevent damage to the
printer.
This chapter contains the codes and diagnostic tools to aid in providing
corrective action for a malfunctioning printer. To determine the corrective
action to repair a printer, look for the following information:
• A description of a problem, see “Symptom tables” on page 2-79.
• Information from the operator panel of the printer.
– Models E238, E240, and E240n have an operator panel containing
lights and buttons. For diagnostic information specific to these
modes, see “Diagnostics—E238, E240, and E240n” on
page 2-2.
– Models E340 and E342n have an operator panel with messages.
For diagnostic information specific to these models, see
“Diagnostics—E340 and E342n” on page 2-50.

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
2-2 Service Manual
lights solid.
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: NVRAM is on the operator panel printed circuit board while secure
NVRAM is on the controller card. Check margin alignments after
replacing the operator panel assembly. See “Printhead service
