Drum Unit Removal - Ricoh C217 Service Manual

7.6 DRUM UNIT REMOVAL

[A]
1. Remove the ink from inside the drum by disabling the ink detection
circuit. The ink detection circuit can be disabled if the main switch is
turned on while both the Auto Cycle key and the Reset key are pressed.
If this mode is accessed, prints can be made even though the ink
detection pin is not in contact with the ink on the ink roller (see page 2-26
Ink Supply Control). When the main switch is turned off, this condition is
reset to normal operation.
2. Turn off the main switch and disconnect the power plug.
3. Remove the front cover (4 screws) and rear cover (6 screws).
4. Open the scanner unit, and turn the drum manually until the drum master
clamper [A] on the drum moves into the top most position.
NOTE: To find out the correct position of the drum for the above, refer
to the rear end of the drum shaft. When the drum master
clamper is positioned exactly at the top, the round part of the
shaft faces the long hole as shown [B]. (The rib [C] of the drum
drive pulley will meet the long hole [D].)
(Refer to page 5-32 for drum caution.)
