Laserprodukten van klasse I worden nie t al s ongevaarlij k aangemerkt. De printer is voor zien van een laser van
klasse IIIb (3b), dat wil zeggen een gallium arsenide-laser van 5 milliwatt met e en g olflengte van 770-795
nanometer . Het laser gedeelt e en de printer zij n zo ont worpen dat bij normaal gebru ik, bij onde rho ud of repar atie
conform de voorschriften, nooit blootstelling mogelijk is aan laserst raling 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.
Lasersystem et og printeren er udformet således, at mennesk er aldrig udsættes for en laserstråling over Klasse
I-niveau ved normal drift, brugervedligeholdelse eller obligatoriske servicebetingelser.

Most paper jams can be avoided by correctly loading paper and specialty media in the printer.
The following hints can help prevent paper jams:
• Do not load wrinkled, cre ased, or damp media.
• Nev er mix media types within a tray.
• Flex, fan, and straight en the media stack before loading it.
Note: Make sure the media stack is belo w the maximum media fill indi cators on the 250-sheet tray before
pushing the tr ay into the printer.
• Push all trays snugly into the print er after loading them.
• Make sure paper guides are positioned before loading the paper or specialty media.
• Do not remov e tr ays while a job is printing. Wait for a Load Paper light sequenc e.
• Before loading transparencies, fan the stack to prevent sheets from sticking together.
• Do not use envelopes that:
– Have exce s sive cur l
– Are stu ck together
– Are damaged in any way
– Contain windows, holes, perforations, cutouts, or embossments
– Have metal clasps , string ties, or metal folding bars
– Have po st age st a m ps atta ched
– Have any exposed adhesive when the fl ap is i n the sealed position
• Use only recommended media. Refer to the Card Stock & Label Guide available on the Lexmark Web site
at www .l exmark.com for more information about whi ch m edia provides optimum results for the curr ent
printing environment.

2. Diagnostic information
Start
CAUTION: Unplug power from the printer before connecting or disconnecting any other cable,
assembly, or electronic card. This is a precaution for personal safety and to pr event 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 correc ti ve action to repair a prin ter, look for the following information:
• A description of a problem, see “Symptom tables” on pa ge 2-37.
• Information from the operator panel of the printer.
– Models E250d and E250dn hav e an operator panel containing lights and buttons.
Warning: Paper clips are commonly used near printers and can become lodged in the paper path. Always
check for debris in the paper path.
Diagnostic information 2-1
4512-220, -230
Po wer-On Self Test (POST) sequence
When the printer is turned on, it performs a POST. Check f or correct POST functioni ng 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 tem perature of the fuser) and t hen stays on.
4. If there is a problem in the printer such as a paper jam, the panel lights indi cate the problem. See
“Common primary light patterns” on page 2-3 for more information.
5. The printer cycles down into standby mode, and lights solid.
Light pa tte rn s an d er ror mess ag es
User attendance messages, paper jam errors, and service errors display a light pattern. This may be all the
information that is needed. However, if is double- clicked on the panel, a second pattern may appear wi th
more detailed information. If is double-click ed again, the first pattern usual ly returns. Not all initial level light
patterns have secondary patterns; when double-clicking, the pattern does not change.
All service errors are indi cated 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 2-25) indicate specific error s. See “Service codes” on page 2-23.
Note: If data is sent to the printer and all lights flash immediately, and double-cli cking does not change the
display, there may be a code problem. Contact the next lev el of support.
