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.

Service codes

All service errors are indi cated by all lights flashing as the primary notification or code. The secondary light pattern indicates an area or function which has the error. Tertiary codes (shown on the following p ages) indicate specific device e rrors. When all lights flash, double-click to see the secondary code. Doub le-click again to see the tertiary code. Double-click a third time to return to the primary light pattern.

In the fol lowing example:

• The primary light pattern indicates a service error (all flashing). Double-click for more information.

• The secondary light pattern indicates a fuser , toner sensor, or fan error. Double-click for more

information.

• The tertiary light pattern indicat es the fan has stalled. Double-click again and the original primary light

pattern will appear.

Note:

• The printer cannot directly determine that a fan has failed, but can sense the higher temperature at the

fuser or printhead.

• If data is sent to the print er and all lights flash simultaneously, and double-clicking does not produce a

secondary code, ther e m ay be a code problem. Contact the next level of support.

Blank pages can be caused by a defective printhead assembl y, LVPS/HVPS, or contr oller card.

• Printhead errors typically result in printer service erro rs unl ess there is bloc kage of the beam or dust on the lens.

• Blank pages typically are caused by the PC roll not being properly charged. Try a different PC kit.

Unplug the printer, and check the cable continuity between the LVPS/HVPS connector marked OPC (at PCN 2) and the correspondi ng wire form (spring) found about 14 mm above and to the ri ght of the transfer roll gear.

• If there is not continuity, call the next level of service.

Printhea d assembly mech an i cal adju stment

A printhead needs to be correctly positioned after it has been removed. Ali gn it to the frame or use the same position as the removed printhead. An indicator is located at the front right-hand screw for reference.

Note: Skew is caused by a sheet being fed through the printer while misaligned. The entire image is rotated relative to the sheet edges. However, a mechanically misaligned printhead causes the horizontal lines to appear skew ed while the vertical lines remai n parallel to the vertical edges.

Paper feed

skew

There are no adjust men ts for skew. Check the pick roll (paper pick assembly) for wear, the paper path for obstruction s, the fuser for proper setting, and the tr ay paper guides for fit to the media.

T o adjust the printhead:

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 elec trostatic 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 the

part is ready to be installed into the printer.

• Make the least-possible body mo vements to prevent an increase of static electricit y fr om

clothing fibers, carpets, and furniture.

• Put the ESD wrist strap on y our wrist. Connec t the wrist ban d to the sy ste m ground poi nt. Thi s

discharges any static electric ity in your body to the print er.

• Hold the ESD-sensiti ve part by its edge connector shroud (cover) ; do not touch its pins. If a

pluggable module is being remov ed, use the correct tool.

• Do not place the ESD-sensitive part on the MFP cover or on a metal table; if the ESD-

sensitiv e part needs to be put down 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 m ake a discharge path from y our 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 person nel. Install

machine covers when the machine is not being worked on, and do not put unprotect ed ESDsensitiv e parts on a tab le.

• If possib le, keep all ESD-sensitive parts in a grounded metal cabinet (case).

• Be extra car eful in working with ESD-sensitive parts when cold-weather heati ng is used,

because low humidity increases static electricity.

Removal proced ur e s

Note:

1. Remove the toner cartridge and media tray before removing other pri nter parts. The toner cartridge should

be protected from light while out of the printer.

2. We recommend disconnect ing all external cabl es from the printer to pre vent damage during service.

3. Unles s other wise stated, reinstall the parts in reverse order of removal.

4. When rein stalling a part held with several screws , st art all scr ews before final ti ghtening.
