Printer Problems
The printer or scanner does not work at all.
Check that the printer or scanner has power and is properly
connected to the computer. Also make sure your printer has
paper in it. If you are using more than one serial port and one is
for your printer, check the primary and secondary port settings
(COM1 and COM2) in your application program.
If you connected a scanner or a parallel port network adapter to
the parallel port, make sure you set the port for bidirectional
operation (PS/2
mode) in the SETUP program, as described
on pages 1-12 and 1-13.
The printer prints garbled information
Check the printer manual for the printer’s correct DIP switch or
control panel settings. Also, make sure you have the proper
drivers installed for your printer and make sure you’ve
selected the correct printer within your software application.
Option Card Problems
A newly installed option card is not working correctly.
Make sure the option card is installed correctly and is
well-seated in its slot. Run SETUP to update your configuration
after you install the card and perform setup procedures for any
software you are using with the card.
See the documentation that came with the option card to set
any necessary DIP switches or jumpers on the card. The
computer may also have some jumpers that must be set for the
option card to work properly. See Chapter 3 for system jumper
information.
