8-24 Phaser 7750 Printer Service Manual
Replacement Procedure
Note
Ensure the developer assemblies are fully and evenly seated when
reinstalling the imaging unit plate assembly. There is a locating pin at the
back of each developer housing assembly.
Lightly tug the wires to ensure that they are not pinched by the plate or
developers while reinstalling.
Center the connectors flat against the wire guide with the yellow developer
connector further to the right.
Caution
Be very careful not to catch any of the wires on the left-hand side of the plate
while re-installing. There are two locating holes in the imaging unit plate
assembly that correspond to locating pins on the frame of the printer. Failure
to align the holes with the pins prior to tightening screws could result in
bending the plate.
