Chapter 1. Diagnosing Problems
Maintenance Analysis Procedures (MAPs)
Defining The Problem
These Maintenance Analysis Procedures (MAPs) are designed to aid in diagnosing printer problems. The MAPs
use a sequential plan for isolating the possible causes of printer problems and point you to the part needing
adjustment, repair, or exchange.
Suggestions for Using the MAPs
v
Discuss the printer symptoms with the operator.
v
Verify that the current configuration is correct. See Appendix A, Printer Configuration, on page 484, or the
IBM
4247 Printer Model A00 User’s Guide, SA24-4404. Or the IBM 4247 Printer Models 001, 002 User’s Guide,
SA24-4408. Or the
IBM 4247 Printer Model 003 User’s Guide, S544–5780
v
Verify that the environment, the paper and the forms used are within specifications. See Appendix B, Supplies,
Forms, Paths and Environmental Considerations, on page 531.
v
Make a quick visual inspection for problems — loose or broken parts, disconnected connectors, or forms jams.
This check may quickly identify problem areas.
v
The normal place to start a service call in these MAPs is at
″
MAP 0100: START OF CALL
″
on page 23. This
MAP sends you to a Field Replaceable Unit (FRU) or to another MAP that is indicated by the symptoms. If you
bypass
″
MAP 0100: START OF CALL,
″
and start the service with another MAP, you may be using the wrong
MAP. The questions in that MAP may not refer to your symptom and may send you to the wrong resolution.
v
These MAPs are an aid in solving most problems. If you misunderstand instructions or questions, a MAP may
lead you to an incorrect resolution. Start again in the MAPs and read each step carefully. If, after going through
the MAPs a second time you still have no solution to the problem, the printer may have two interrelated
problems or an intermittent problem. Use other diagnostic techniques or call IBM Support for aid.
v
Read carefully! The MAPs will aid you in resolving the situation only if you follow every instruction and answer
each question accurately.
