SAFETY INFORMATION
This printer is a page printer which operates by means of a laser. There is no possibility of danger from
the laser, provided the printer is operated according to the instructions in this manual provided.
Since radiation emitted by the laser is completely confined within protective housings, the laser beam
camot escape from the machine during any phase of user operation.
For United States Users;
[Laser Safety]
This printer is certified as a Class 1 Laser product under the U.S. Department of Health
and Human Services
tion Control for Health and Safety Act of 1968. This means that the printer does not
produce hazardous laser radiation.

Radiation Performance Standard according to the Radia-
[CDRH
The Center for Devices and Radiological Health
Administration implemented regulations for laser products on August 2,1976. Compliance is mandatory for products marketed in the United States. The label shown below

1.4.8 Optional Memory
If you have difficulty printing complex, graphics-intensive pages or if you regularly use
downloaded fonts, you may need to install the optional SIMM sets on this printer’s controller
board. The printer’s controller board comes with 2.0 MB of RAM installed.
By installing additional
SIMMS,
you can increase the printer’s memory to a total of 64 MB,
including the resident memory.
EPSON supplies several types of memory option (SIMM). Other
SIMMS
can be purchased from
other vendors. Be sure the SIMM meets the requirements listed below.
■ 72-pin type
■ Capacity is one of the following: 1,2,4,8,16,32 MB

A maximum of 250 sheets can be loaded in the 250-sheet lower paper cassette (option). The
cassette must be capable of handling the paper size, however. (The lower paper cassette unit can
hold letter or A4 paper.)
The driving force for paper feeding and transport is from the transmission gear. All electrical

2.1.1.6 Image Transfer
Image transfer is the process of transferring the toner image created on the PC drum during the
developing process to the paper. This printer uses the roller image transfer method, instead of
corona image transfer, as the image transfer process. In roller image transfer, there is no generation
of ozone as there is with corona discharge.

2.1.1.7 Fusing
Fusing is the process of fixing the toner image transferred during the image transfer process onto
the paper. This printer uses the heating roller method for fusing. The heating roller method fixes
the toner image with an upper fusing roller that is heated by the heater lamp.
After power is turned on, the heater lamp lights up until the temperature of the upper fusing roller
reaches 165° C (329” F). After warm-up, the mechanical control board controls the ON/OFF
operation of the heater lamp, based on the THl signals from the thermistor.

2.1.2.2 Paper Take-Up Sensor and Paper Exit Sensor
The paper take-up sensor has three functions:
1. To detect the top edge of paper. The engine starts printing when the detection signal
is received.
2. To detect paper size. The printer detects the time it takes for paper to pass the paper
take-up sensor during paper feeding. If this time is
if the time is short, shorter paper is feeding.
3. To detect paper jams and feed jams.
If the paper take-up sensor does not turn on for paper feeding, the printer detects a feed jam. A
feed jam is a paper jam that occurs in the feed process.
If any of the following conditions is detected, the printer detects a paper jam. A paper jam is a jam
that occurs in the printing process area.

The L DATA signal is the laser ON/OFF signal. When it is LOW, the laser emits, and when it is
HIGH, the laser stops emitting. L DATA is the combination of the two signals in the figure below.
If the VIDEO or the FORCED LASER DIODE ON signal is activated (LOW), the L DATA signal
will be active. The VIDEO signal is an image signal sent from the video controller board

Manual
Print data and commands transmitted from the host computer via parallel, serial, or optional
interfaces are read using the interrupt process of the CPU and stored in the DIUM input buffer.
Data and commands in the input buffer are processed by the CPU, which then stores the printing
bitmap data (image data) in the V (video) -RAM (image buffer) in the DRAM. The size of the
V-RAM depends on the available DRAM size. A “PRINT OVERRUN” occurs when the V-RAM is
so small that the CPU cannot process data faster than it is transmitted to the engine controller
board. If such an error occurs, the user can increase the V-RAM by using
SelecType
setting “PAGE
PROTECT”.
The
E05A91
transmits image data stored in the V-RAM to
E05A92.
The
E05A92
changes image the
data format from 32 bits parallel data to serial data, and stores it in the internal temporary buffer.
The temporary buffer has a capacity equivalent to several lines. This is controlled by the
E05A92,
which synchronizes and transmits the tempora~ buffer’s data to the engine controller board. The
E05A92
then manipulates the printer data according to the
BiRITech
and
EMGTech
settings.
