Transfer Roll Service Check
FRU Action
Transfer roll
• 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.
