at the 3 o'clock position, is a timing hole. The
white drive gear also has a timing hole.
6. Rotate the drive gear in a clockwise direction
until these two holes are lined up together. Use
a scribe or some other similar tool to check that
the holes are aligned.

paper cassette position cam. Verify that the
cam is fully seated into the drive gear. Locate
the timing hole in this gear.

the timing hole and rotate the gear to the 7
o'clock position to line up with the timing hole
in the printer frame.

the black gear you previously removed.
