Completing a Service Call
After resolving any printer problem, complete the service call as follows:
1 Reassemble the printer.
2 Perform the every-call cleaning procedure, described in Chapter 9, “General Printer
Maintenance”.
3 If you have removed the printer’s diskette(s), reinstall them.
4 Power-on-reset the printer.
5 Clear the error log. (See the procedure described next.)
6 Run test prints in both the simplex and duplex mode from both the upper and lower
paper cassettes.
7 Fill in the Repair/Maintenance log. Make sure the problem description and steps taken
to resolve the problem are clearly documented.
Do not touch the surface of the photoconductor belt; this
damages the belt and results in poor print quality.
