HP CM8060 Color MFP Kundendienst Handbuch Seite 90

If the service call was due to an image-quality issue, follow the image-quality troubleshooting
procedures. See the image quality troubleshooting guide.
Repair activities
1. Try to duplicate the problem by running the same type of job that the customer was running.
2. When diagnosing or repairing an error in a particular subsystem, exercise the system by trying to
determine the error or failure location. If the same error code returns, access CDFT and enter the
appropriate fault tree for that error code and follow the fault tree. When the failure is found, repair
as necessary and exercise the system again after the repair to validate that the subsystem has
been repaired.
Final activities
1. Inspect the media transports for dust, and then vacuum as needed.
HINWEIS:
