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
cannot 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 (DHHS) Radiation Performance Standard according to the Radia-
tion Control for Health and Safety Act of 1968. This means that the printer does not
produce hazardous laser radiation.
[CDRH Regulations]
The Center for Devices and Radiological Health (CDRH) of the U.S. Food and Drug
Administration implemented regulations for laser products on August 2,1976. Compli-
ance is mandatory for products marketed in the United States. The label shown below
indicates compliance with the CDRH regulations and must be attached to laser products
marketed in the United States.
WARNING: Use of controls, adjustments or performance of procedures other
thanthosespecified in this manual may result in hazardous radiation exposurel

EPL-3000 /ActionLaser 1300 Sewice Manual General Description
1.1 FEATURES
The EPSON@ EPL-3000 and the ActionLaserTM 1300 are non-impact page printers that combine a
semi-conductor laser with electro-photographic technology. These printers are small and light, and
feature high-speed, high-resolution printing. Maintenance is very easy because of various built-in
diagnostic functions. The main features are:
c1 No ozone
Ct Printing speed -- 4 ppm (pages per minute)
cl Resolution -- 300 dpi (dots per inch)
c1 Light weight -- about 7 kg (15 lb.)
c1 Small footprint
Q Easy maintenance
c1 HP@ LaserJet@ 4L emulation mode (PCL@5e emulation)
D 22 built-in scalable fonts (8 Agfa@ and 14 TrueType fonts)
a Resolution Improvement Technology (RITech) refines the print quality by eliminating jagged
edges from images and characters.
c1 Two levels (35~o less and 50~0 less) for Toner Save Mode
c1 Optional EPSONScript Level 2 (PostScript@ compatible) SIMM module
c1 Optional WPS (Windows Printing System) SIMM module
Q 1 MB standard RAM and up to 5 MB RAM with the addition of optional SIMM
c1 Bidirectional parallel interface
c1 High-speed parallel communication rate of approximately 125 KB/second
c1 A multi-user, multi-emulation mode (EPL-3000)
c1 IES (Intelligent Emulation Switch) allows switching between EPSONScript mode and PCL5e
emulation mode.
c1 SPL (Shared Printer Language) enables switching of the printer mode by command.
