After replacing the Process Drive, Drum Maintenance Pivot Plate or
the Drum Maintenance Camshaft (or any component requiring
removal of the Process Drive), the printer may experience Front
Cover jams from Tray 2. The jam occurs with paper in the Preheater
and C3T jam errors (strip flag timeout during transfix) recorded in Jam
History. In many cases, Tray 1 (MPT) prints with no jams.
These symptoms indicate that the Transfix Load Module is incorrectly
timed resulting in a late arrival of the leading edge at the strip flag.
The likely cause is the position of the Drum Maintenance Camshaft
gear in relation to the Process Drive gear. To correct this problem, see
“Timing the Drum Maintenance Camshaft” on page 6-9.

out from the side of the cone nut on the motor shaft, is engaged with
the side rail. Install and torque the 4 screws to 12 in. lbs. Reconnect
the harness. Before restoring power, center the Printhead in its range
of motion using a flatblade screwdriver to turn the X-Axis Motor shaft.
