1. Determine the symptoms:
• What are the hardware connections, software connections and software
applications?
• Did the printer operate at all previously? If so what change(s) occurred?
• Does the printer work by itself?
∗ Print hardware and error reports (see the user manual).
∗ Print a start page.
• Do you hear abnormal sounds (at power up or feeding paper)?
• Is the control panel blank, garbled, or unresponsive to the online button?
Refer to Section F
Normal Operations to compare the normal actions of the printer to the

review this list before returning the printer to Digital.
Before proceeding, make sure the paper trays are filled with paper and installed in the printer.
