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.
