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.

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.

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 (5­20 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 lights solid.

2-2 Service Manual

4511-xxx

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: If you send data 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.
