HP (Hewlett-Packard) 220240 Printer User Manual


 
6.5 Service Call Messages
Service call messages indicate that the printer requires servicing by
a qualified Digital service representative (see Chapter 8 for service
information). Service messages are displayed as XX SERVICE (where XX
is a number from 50–99).
NOTE: Before calling for service, try to clear the error message by powering
the printer off. After a few seconds, power the printer on. If the error message
is still displayed, power the printer off and call for service.
6.6 Common Operating Problems
Table 6–5 lists common operating problems and their possible solutions.
Follow the corrective actions in the order in which they are listed. Check
the table to solve printer problems before calling for service.
NOTE: Since many problems with print quality could be caused by a faulty
component in the EP-S cartridge, it is recommended that you keep a spare
cartridge as a replacement. If you are experiencing a problem with print
quality that is not listed in the troubleshooting table, you can replace the
EP-S cartridge to see if that solves the problem before calling for service.
CAUTION: Be careful when checking items inside the printer, because the
fixing assembly may be hot.
