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.

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)
•
