Desk dehumidifier (P/N 34860030): for 120 V specifications only
Two (2) M4 × 8 S tight screws (P/N B3324080)
Procedure
1. Remove the upper and lower drawers.
2. Remove the three screws holding the desk
rear cover and then the cover.
3. Pass the desk dehumidifier cable to the
machine rear through the cable hole in the
machine right.
4. Attach the desk dehumidifier using the two M4
× 8 S tight screws.

(4) Adjusting the position of the rack adjuster
Perform the following adjustment if there is a regular error between the center lines of the copy image and the original on the
paper fed from the drawer.
Procedure
Start
Enter maintenance mode.
Run maintenance item U993.
Select “VTC PG1” and output
a test pattern.
Is the image correct?
Yes
Exit maintenance mode.
End
No
Correct image Output
Loosen the three screws holding
the rack adjuster and change the
position of the adjuster so that
the centers of the original and
the copy image are aligned.
• For output example 1, move
toward the machine front ( ).
• For output example 2, move
toward the machine rear ( ).

2-1-1 Mechanical construction
The paper feed desk feeds paper from either of its two drawers to the copier main body. When paper is fed from the lower
drawer of the paper feed desk, the desk feed clutch (DFCL) is operated to rotate the desk feed roller and pulley to carry the
paper into the copier main body.
