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 (Appendix A, “Printer
configuration”).
v
Verify that the environment, the paper and the forms used are within specifications. See Appendix B, Supplies,
Forms, Paths and Environmental Considerations (Appendix B, “Supplies, forms, paths, & environmental
considerations”).
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” (MAP 0100: START
OF CALL). 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.
