After servicing the printer, manually set the following assemblies to their home
position before powering on the printer. If the assemblies are not home, gears
in the Process Drive can grind or the printer can generate errors.
■ Printhead (tilted forward and disengaged from tilt gear)
■ Head Tilt Gear (disengaged from Process Drive train; arrows on left frame
point to each other)
■ Wiper Blade (bottom of travel)
■ Process Drive (holes on Transfix Camshaft and Drum Maintenance
Camshaft line up with marks on frame, large gears within assembly line

When the Wiper Assembly is homed, the Wiper Blade should be moved all the
way to the bottom of the printer. When the Wiper Blade is at the bottom, you
