Appendix C

Problem Solving and Maintenance

This appendix approaches troubleshooting from several directions. The first section uses a columnar format to match solutions with problems. Other sections cover beeper error warnings, hexadecimal data dumping, coding and 7-bit solutions, and specific solutions for several popular personal computer systems.

Printer does not print

Make sure that the printer is turned on

 

and is on line. Both the POWER and

 

ON LINE lights should be on.

 

Make sure that the printer and computer

 

are connected. Be certain you are using

 

the correct cable.

 

If the printer still does not print, try the

 

self test procedure (see Chapter 1). If the

 

self test works correctly, the printer is all

 

right and the problem lies elsewhere. If

 

the self test doesn’t work, call the toll-free

 

number for assistance: 1-800-421 -5426.
