Date: Apr. 8, 1994

COPIER : Z-20

No. : SP-1717

1. TROUBLE SHOOTING STACKING TROUBLE.

2. CHANGE IN BRACKET C
(FOR 200 V SERIES MACHINES ONLY).

1. Trouble shooting stacking trouble.

1.Model name: Z-20 / 23 / 25 / 27

2.General: The position of the pressure roller has been moved 1.2 mm towards the paper feeding

side as a trouble shooting measure to alleviate the problem of copy paper stacking in
the delivery section of the machine.

3.Description: The shapes of PF lever F, PF lever R, the fusing scraper, the fusing front paper guide
and the fusing actuator have been changed in accordance with the change in position
of the pressure roller.

Changed PF lever F, PF lever R.

2. Change in bracket C (For 200V series machines only).

1.Model name: Z-20 / 23 / 25

2.General: The C bracket unit has been changed in the 200V series machines bound for SEEG,

Great Britain, Australia and South Africa to alleviate the problem of electrical noise in
compliance with standards.
Note: The C bracket unit change has been carried out in the 200V series machines

bound for all OEM destinations.

3.Description: The noise reduction capacitor (0.47µF) forking from the CL harness in the C bracket
unit has been moved as close as possible to the AC cord and noise filter circuit in the
main power PWB as a trouble shooting measure to improve noise reduction efficiency.
