Tips on preventing jams

Paper path

*Measurements are approximate paper lengths (millimeters)

**Sensors are measured at rotation/position which they are tripped

4512-220, -230

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, creased, or damp media.

•Never mix media types within a tray.

•Flex, fan, and straighten the media stack before loading it.

Note: Make sure the media stack is below the maximum media fill indicators on the 250-sheet tray before pushing the tray into the printer.

•Push all trays snugly into the printer after loading them.

•Make sure paper guides are positioned before loading the paper or specialty media.

•Do not remove trays while a job is printing. Wait for a Load Paper light sequence.

•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 embossments

–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 media. Refer to the Card Stock & Label Guide available on the Lexmark Web site at www.lexmark.com for more information about which media provides optimum results for the current printing environment.

Tools

The removal and adjustment procedures require the following tools and equipment:

•Spring hook

•Needle nose pliers

•Volt-ohmmeter

•#1 and #2 Phillips screwdriver

•Slotted screwdriver

•Flashlight

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 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 2-37.

•Information from the operator panel of the printer.

–Models E250d and E250dn have 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.

4512-220, -230

Power-On Self Test (POST) sequence

When the printer is turned 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 2-3 for more information.

5.The printer cycles down into standby mode, and 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 that is needed. However, if is double-clicked on the panel, a second pattern may appear with more detailed information. If is double-clicked again, the first pattern usually returns. Not all initial level light patterns have secondary patterns; when double-clicking, 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 2-25) indicate specific errors. See “Service codes” on page 2-23.

Note: If data is sent 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.
