Your
application has
locked the computer, making it
unresponsive to keyboard
commands.
Reset the computer and try again. If resetting the computer
does not help, turn it off, wait 20 seconds, then turn it on again.
Some software, like OS/2,
®
UNIX,
®
or NetWare,
®
needs a
minimum of 8MB to 16MB of RAM to work correctly. Check
your software documentation for the minimum memory
requirements. If necessary, add memory modules using the
instructions in Chapter 3.
Printer or Scanner Problems
The printer or scanner does not work at all.
Check that the printer or seamer 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.
Make sure the computer’s jumpers are set correctly. Also, make
sure your operating system is assigning ports correctly.
If you connected a scanner or a parallel port network adapter to
the parallel port, make sure you set the port for bidirectional
operation (PS2 mode) in the SETUP program, as described on
page 1-17.
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 you’ve selected the correct printer within your
software application.
