Switch A-1: Emulation
Select the mode compatible with your computer and software. In the
Standard/Epson mode,theprinteroperates liketheEpson LQ-860/850.
In the IBM mode, it operates like the IBM Proprinter X24E/24P,
Ps/1 .
The ON position selects Standard/Epson mode. The OFF position
selects IBM mode.
Switch A-2: Auto Emulation Change (AEC) Mode
This switch selects the Auto Emulation Change (AEC) mode.
When the AEC mode is enabled, the printer automatically judges the
Emulation which your application program uses.
Switch A-3: RAM Usage
Inorder todownloadcharacters thisswitchmustbe intheOFF position.
The printer then uses its RAM memory for storing character patterns
and provides only a one-line print buffer. If you leave this switch ON,
the printer uses its RAM memory as an input buffer, allowing the
computer to send data faster than the printer prints.
Switch A-4: Auto LF with CR
If you leave this switch at theON position, a separate line-feed code is
required from your computer to obtain a line feed. If you move this
switch to the OFF position, the printer performs both a carriage return
and line feed each time it receives a carriage-return code.
Most computer systems send a line feedcode, or both a carriage return
and line feed, at the end of each line, so this switch should be left ON.
If you get double line spacing when you expect single spacing, or if
lines overprint each other, try changing the setting of this switch.
Switch A-5: Auto Sheet Feeder
In order to use the optional automatic sheet feeder (SF-1ODS),move
this switch to the OFF position.
Otherwise leave it ON.
Switch A-6: Graphics Direction
When printing in graphics mode, the printer may either print bi-
directionally (in alternate directions) for speed or in one direction only
(uni-directional for increased accuracy). For practically all purposes,
however, bi-directional printing is sufficiently accurate.
