Return parts

Engineering periodically analyzes returned parts for failure modes. Include a printed quality page and a menu
page, before and after the repair, and tag any returnable parts with a description of the failure.

Service recommendations

Before leaving the printer, check the following:
•
Be sure printer is on a flat, level, strong tabletop or level floor. 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.
•
If you have serviced the finisher option, and in the process pulled it away from the printer during repair,
ensure that it is properly aligned with the printer.

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)
When you make voltage readings, always use frame ground unless another ground is specified.
