• Print a Demo page.
• If additional paper sources are installed, print a Demo page
from each of these, (if possible).
Note: Failure to print from an additional tray or feeder may imply
one or more pins are bent in the mating connector.
Return Parts
Engineering periodically analyzes returned parts for failure modes.
Please Include a printed test (DEMO) page, before and after the
repair, and tag any returnable parts with a description of the failure.
Recommendations For Service
Before leaving the printer check the following:
• Be sure printer is on a single, flat, strong tabletop. This is very
important for color printers that use belts. Check and set
registration as necessary.
• Shake all cartridges and be sure they are correctly installed and
fully seated.
• While the cover is open, wipe any residual toner from the LEDs
using a lint free cloth.
Tools
The removal and adjustment procedures require the following tools
and equipment:
• Magnetic tip Phillips screwdrivers, large and small
• Flat-blade screwdrivers
• Analog volt ohmmeter (a digital volt ohmmeter may also be
used)
• Needle nose pliers
• Tweezers, C-ring pliers
• Magnifier (10 times or equivalent)
• 6-angle wrench (1.5 mm)
When you make voltage readings, always use frame ground unless
another ground is specified.
