Step
18 (Check eliminator of trans. chute assy)
Is there any dirt or grime clinging to the eliminator of the trans.
chute assy?
19 (Check eliminator of trans. chute assy)
Is there conductivity between the eliminator of the trans. chute
assy and the PTN (or the SG)?
20 (Check drive assy)
Are the gears of the drive assy rotating normally in relation to
the gear idler of the fuser assy?
• Rotate the main motor gears by hand to check them.
21 (Check rotation of heat roll/pressure roll)
Are the heat roll/pressure roll of the fuser assy rotating nor-
mally?
• Rotate the main motor gears by hand to check them.
22 Is there any paper or other material in the exit actuator section?
23 (Check exit actuator)
Does the exit actuator move smoothly away from the sensor
section of the exit sensor when paper is present, and then move
to block off the sensor section of the exit sensor when there is
no paper present?
24 (Check exit sensor)
Is the exit sensor functioning normally?
25 Is there any paper or other material in the regi. actuator section?
26 (Check regi. actuator)
Does the regi. actuator move smoothly away from the sensor
section of the regi. sensor when paper is present, and then move
to block off the sensor section of the regi. sensor when there is
no paper present?
27 (Check regi. sensor)
Is the regi. sensor functioning normally?
