PDOS FOR THE LQ-850/950/1050 PRINTERS
The following contains information on using the LQ-850/
1050 PDOS diagnostics (#B765108801 for MS-DOS compatible,
#B765108901 for QX-16 computers) to troubleshoot the LQ-
850/950/1050 series printers,
USING PDOS:
To use PDOS on the LQ-850/950/1050 printers, a serial
connection must be made to the host computer using a
suitable cable (Epson part no. 8297 connects the LQ's
6-pin DIN connector to a standard DB-25 port). This
cable must be connected to COM1:* on the host computer.
DIP switch positions 2-3 and 2-4 must be set to ON, and
2-5 and 2-6 to OFF.
8 data bits,
This sets the printer to 9600 baud,
and no parity.
PDOS will automatically
activate and configure the host computer's serial port.
PDOS is then started by booting off the supplied disk,
and following the prompts given on screen (a detailed
manual is available on the disk).
USAGE ON LQ-950:
The PDOS diagnostics for the LQ-850/1050 also operate
on the LQ-950 when the following precautions are
observed:
1) When the PDOS menus prompt for the selection of
printer type,
the LQ-850 should be chosen.
2) Jumper J7 on the MONMA board must be moved from the
136 to the 80 column position when performing the
carriage motor test. The jumper should then be
returned to its original position when testing is
completed.
* Applies to MS-DOS compatible version of PDOS.
