Transfer roll
Note:
Do not touch the transfer roll except at its ends. Place a sheet of paper over the roll to
prevent damage from finger oils or hand lotion.
Check the springs in the left and right transfer roll bearings. Do not try to move the left
spring. The bearing assemblies should support the transfer roll, applying evenly distributed
forces to the PC drum.
Replace the transfer roll assembly if the springs or bearings show signs of damage, or
fatigue.
Inspect the transfer roll for signs of wear, damage or contamination.
Replace as necessary.
