ADJUSTMENT

3 - 61

3.11.3 Black developer unit lift up/down timing adjustment

Perform this adjustment only when the stop position of the black developer unit lift up/down lever devi-

ates from the reference and a CEB0 error occurs.

The reference position means that the rib of the developer unit cover and the cutout of the black devel-

oper unit lift up/down lever are not overlapped as shown in Figure "A". (The cutout is in the 9 o'clock

position.)

Adjustment procedure

(1) Perform 03-460 Black developer unit lifting movement ON/OFF (continuous lifting movement)

and check the stop position of the black developer unit lifting lever. At this time, check the devia-

tion amount between the rib and the cutout of the lever.

(2) The stop position is "B" (the cutout is lower than the reference position):

Make the value of the adjustment code (05-499) smaller so that the stop position is closer to the

reference. Making the value smaller by 1 turns the lever circumference by approx. 3 mm.

Note: Note:

If the adjustment cannot be performed though 0 is input, the clutch may have failed. Examine the

clutch.

(3) The stop position is "C" (the cutout is upper than the reference position):

Make the value of the adjustment code (05-499) larger so that the stop position is closer to the

reference. Making the value larger by 1 turns the lever circumference by approx. 3 mm.

Note: Note:

If the adjustment cannot be performed though 8 is input, the clutch may have failed. Examine the

clutch.

Note:

If an error occurs even though this adjustment is performed, other causes may be considered.

Examine and check the defect according to the methods in troubleshooting.
