AROUND THE DRUM
8. Install the new drum in the drum unit, then position and secure the
bearing holder.
NOTE: a) When setting the drum in the unit, be careful not to strike it
against the unit frame or the pick-off pawls [F].
b) Do not bend the bearing holder. Make sure that the bearing
holder is in contact with the bearing, as they are both used to
ground the drum. If they are not in contact, solid black copies
may appear.
9. Install the drum unit in the copier and remove the drum protective sheet.
NOTE: Be sure that the drum unit is secured with the screw.
10. Install the other remaining units in the copier.
11. Clean the optics and plug in the copier.

switch to enter the SP mode.
NOTE: Release the number keys after confirming that the call service
indicator and the copy counter number "0" are blinking.
13. Enter "66" using the number keys and press the enter key. Press "1",
then the enter key. (The copier performs the drum initial setting and the
beeper sounds 5 times.)
14. Enter "54" using the number keys and press the enter key, then the start
key. (The copier performs ID/V sensor adjustments and the beeper
sounds 2 times after 4 seconds.)
