Some software, like OS/2®, UNIX, or NetWare,@ needs at least
8MB to 16MB of RAM to work correctly. Check your software
documentation for the minimum memory requirements. If
necessary, add more memory as described under “Installing
Memory Modules (SIMMs)” in Chapter 3.
Printer or Scanner 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, check
the primary and secondary port settings (COMl and COM2)
in your application program and in the SETUP program. See
“Configuring integrated peripherals” in Appendix B for
information about serial port settings in SETUP.
If you connected a scanner to the parallel port, make sure the
port is set for bidirectional operation (Bi-directional or EPP
mode). See “Configuring integrated peripherals” in Appendix B
for more information. If you use ECP mode, check your parallel
device software documentation for the correct DMA channel
(DRQ) setting; then set jumpers JP23 and JP24 to match the
setting, if necessary; see “Changing the Jumper Settings” in
Chapter 3 for more information.
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.
In Windows 3.1, select Print Manager and be sure that the
correct printer driver is selected. In Windows 95, check the same
thing in the Printers selection from the Settings menu.
