The precautionary measures itemized below should always be observed when performing repair/maintenance procedures.

DANGER1. ALWAYS DISCONNECT THE PRODUCT FROM THE POWER SOURCE AND PERIPHERAL DEVICES PERFORMING ANY MAINTENANCE OR REPAIR

PROCEDURES.

2. NO WORK SHOULD BE PERFORMED ON THE UNIT BY PERSONS UNFAMILIAR WITH BASIC SAFETY MEASURES AS DICTATED FOR ALL ELECTRONICS TECHNICIANS IN THEIR LINE OF WORK.

3. WHEN PERFORMING TESTING AS DICTATED WITHIN THIS MANUAL, DO NOT CONNECT THE UNIT TO A POWER SOURCE UNTIL INSTRUCTED TO DO SO. WHEN THE POWER SUPPLY CABLE MUST BE CONNECTED, USE EXTREME CAUTION IN WORKING ON POWER SUPPLY AND OTHER ELECTRONIC COMPONENTS.

4. WHEN DISASSEMBLING OR ASSEMBLING A PRODUCT, BE SURE TO WEAR GLOVES TO AVOID INJURIES FROM METAL PARTS WITH SHARP EDGES.

WARNING1. REPAIRS ON EPSON PRODUCT SHOULD BE PERFORMED ONLY BY AN EPSON CERTIFIED REPAIR TECHNICIAN.

2. MAKE CERTAIN THAT THE SOURCE VOLTAGES IS THE SAME AS THE RATED VOLTAGE, LISTED ON THE SERIAL NUMBER/RATING PLATE. IF THE EPSON PRODUCT HAS A PRIMARY AC RATING DIFFERENT FROM AVAILABLE POWER SOURCE, DO NOT CONNECT IT TO THE POWER SOURCE.

3. ALWAYS VERIFY THAT THE EPSON PRODUCT HAS BEEN DISCONNECTED FROM THE POWER SOURCE BEFORE REMOVING OR REPLACING PRINTED CIRCUIT BOARDS AND/OR INDIVIDUAL CHIPS.

4. IN ORDER TO PROTECT SENSITIVE MICROPROCESSORS AND CIRCUITRY, USE STATIC DISCHARGE EQUIPMENT, SUCH AS ANTI-STATIC WRIST STRAPS, WHEN ACCESSING INTERNAL COMPONENTS.

5. DO NOT REPLACE IMPERFECTLY FUNCTIONING COMPONENTS WITH COMPONENTS WHICH ARE NOT MANUFACTURED BY EPSON. IF SECOND SOURCE ICS OR OTHER COMPONENTS WHICH HAVE NOT BEEN APPROVED ARE USED, THEY COULD CAUSE DAMAGE TO THE EPSON PRODUCT, OR COULD VOID THE WARRANTY OFFERED BY EPSON.

aser Beam

TE: The laser beam has a narrower frequency band and more coherent phases than any other light (sunlight, electric light). It has excellent monochromaticity and convergence. A thin laser beam reaches long distances. Because of its convergence characteristic, the laser beam converges into one point, causing high density and high temperature. A laser beam is harmful to the human body.

TE: The laser beam in this printer is invisible.

Figur

Do not expose yourself to the laser beam to prevent

injury (blindness). Do not open the cover that has the laser beam

warning label. If you disassemble or assemble the printer, turn off

the power. If you need to work on the printer with power applied,

strictly follow the instructions in this manual. Understand how the laser beam functions and take

maximum precautions not to injure yourself or anyone around you.

.1 Featuresis printer is a non-impact color page printer that takes advantage of a laser d electrophotographic technologies. It provides 1200/600/300 dpi of solution and 16 ppm (A4/LT) of printing speed for both color and onochrome printing. The main features of the printer are as follows:

GINE FEATURES

A4 tandem engine, a high-speed engine which printing speed is 16 PPM for both color and monochrome printing (when printing A4/LT).Engine for True 1200 dpi of high resolution and full-color printing (however printing speed is reduced by half).

The Duplex Print Unit is equipped as standard. Special types of paper such as thick paper, OHP sheets (transparency), label sealing sheets, and envelopes cannot be printed in duplex.

By using high quality plain paper, higher quality printing is possible.

Capable of printing on thick paper and OHP sheets for laser printers.

Provides easy maintenance of a color laser printer. The users can replace all consumables.

Toner cartridges (C, M, Y, K) Photoconductor Unit Transfer Unit Fuser UnitStandard paper feed devices are the following 2-bin; the MP Tray (up to 100 sheets) and the Lower Cassette (up to 500 sheets, A4/LT).By adding the two optional Lower Cassette (up to 500 sheets * 2 cassettes, A4/LT), a maximum of 1600 sheets can be fed from the 4-bin in total.

Standard paper eject is up to 250 sheets into the Face-down tray.
