PRODUCT DESCRIPTION
EPL-5700L/5700i Revision A
1.1 FEATURES
The following shows features of EPL-5700L/5700i.
ENGINE
Com pact, lightweight A 4 engine
600 dpi resolution, 8 pp m printing speed
Standard paper feeding is by a cassette-like universal paper tray (150
sheets) and a m anua l feed tray (1 sheet).
Option al paper feed ing is b y a A4 or LT lower paper feeder unit (500
sheets).
RESTRICTIONS / DIFFERENCES WITH EPL-5700
1. A network I/F, including external attachment cannot be used.
The compressed data is expanded in real-time by the expansion
circuit and transferred to the engine.
Speed is enhanced by compressed data expansion hardware.
The following functions can be upgraded and speed can be increased
by RAM SIM M expansion.
Enhanced MicroGray printing
Receive buffer capacity
Printing speed
CONTROLLER
A new ly developed host-ba sed controller
CPU: TMP95C001, TOSHIBA
EDO RAM or FastPage RAM (60 ns)
Interfac e
ECP compatible parallel I/F which conforms to IEEE 1284
USB interface
Mou nted with RITech, Enhanced M icroGray
An underline error m ay occur when printing a com plicated image with
600 dpi Enhanced MicroGray printing.
M o unte d with T o n e r Sav e Mod e
Mou nted with bi-directional I/F (IEEE1284)
A host -based printer is possible.
Data compression technology
By sending compressed data from the host, printing with a 2MB
memory is possible.
2. Fonts are not installed.
3. The emulation is not installed.
4. Only the Windows 95/98, Windows NT 4.0 and Macintosh operating
systems (8.1 or later) are supported.
5. The ROP and fill methods change, so there may be differences in
the output.
6. When using halftones, the printed image may be different.
7. There are differences with operation when “Toner out” occurs.
8. The driver UI is different.
9. It can only be connected to a Macintosh with a standard USB
connection. Optional USB board i s not guaranteed.
10. With the standard memory, printing at 600 dpi with MicroGray ON
may not be possible. Also, for a host that is not capable of ECP
communication, printing may not be p ossibl e with standar d memory.
11. The printer status can be displayed on the screen and printing is
possible upon user’s request.
PRODUCT DESCRIPTION FEATURES 8
EPL-5700L/5700i Revision A
12. The recommended host environments are:
W indow s:
Pentium 233 M Hz and 64 M B R AM o r more
Macintosh :
G3 233 M Hz and 6 4 M B R AM or m ore
13. For Windows NT 4.0, EPSON Printer Port Monitor must b e installed
to use ECP.
14. Even if the option RAM is expanded by 16 MB or more, only a
maximum of 13 MB is valid.
15. When using parallel connection, printing is not possible if bidirectional communication is hindered by the following conditions.
There is a printer selecting switch between the PC and the
printer for parallel connection.
Old PC that does not support bi-directional communication is
used.
Unspecified cables are used.
16. If there is no paper in the MP tray, the paper size will become
unclear.
17. Status sheet printing cannot be performed by the printer itself.
18. The printer cannot be shared in a Macintosh network.
