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.

Tools

The remov al and adjustment procedur es require the foll owing tools and equipment:

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.
