Ink Roller Unit Removal - Ricoh C217 Service Manual

7.8 INK ROLLER UNIT REMOVAL

[A]
CAUTION: Never disassemble the ink roller unit. Each part between
the front and rear side plates of this unit has been exactly
adjusted to keep the doctor and ink rollers parallel against
the drum shaft in the production.
1. Turn off the main switch and disconnect the power plug.
2. Remove the drum screen. (Refer to "7.7 DRUM SCREEN REMOVAL.")
3. Remove the drum unit. (Refer to "7.6 DRUM UNIT REMOVAL.")
4. Remove the clamper open lever [A], then remove the drum master
clamper [B] while opening the clamping plate [C].
CAUTION: 1) Position the springs (two on the front and one on the
rear) as shown when reinstalling the drum master
clamper.
2) Do not allow the inside of the clamping plate [C] to
become dirty with ink. If it is dirty with ink, the master
may slip off and the image position on the prints will
move toward the trailing edge of the print during a
printing run.
3) Use a cloth damped with water to clean the inside of the
clamping plate [C]. Never use alcohol or other solvents.
The clamping force by magnet may be weakened.
