COPIER : Z-88

1. PREVENTION OF COPY LAMP DISLOCATION DURING TRANSPORT

2. PREVENTION OF 4/5 MIRROR ADJUSTMENT PLATE CONTACT

3. TROUBLE SHOOTING L5 ERRORS THAT OCCUR WHEN MAKING
REDUCED-SIZE COPIES (70%)

1. Prevention of copy lamp dislocation during transport

1.Model name: Z-88 / SF-2010 / Z-85 / Z-85II

2.General: A support plate has been added to lamp contact plate F in order to prevent dislocation

of the copy lamp caused by shock during transport.

No. : SP-1645

3.Cause: Copy lamps are often dislocated due to shocks caused by severe drops during
transport.

* Since models Z-88 are wire-driven, they are especially susceptible to the

above-mentioned trouble.

4.Description: A support plate will be installed next to the lamp spring as shown in the diagram below.

2. Prvention of 4/5 mirror adjustment plate contact

1.Model name: Z-88 / SF-2010

2.General: The tip of the boss extending from the 4/5 mirror adjustment comes into contact with

the magnifying cam when making enlarged copies. T o prevent this, the boss will be
shortened. (Though models Z-85/85II also use a 4/5 mirror, the position of the
magnifying cam is 1 mm lower than that on the Z-88 series, so the above problem does
not occur. For this reason, the Z-85/85II series will not be changed.)

3.Cause: Prevention of contact between the adjustment plate boss and the magnifying cam.

4.Description: The length of the adjustment plate boss of the 4/5 mirror has been changed from 6.2

mm to 5.5 mm.

Change in boss length.

The parts code for the changed 4/5 mirror adjustment plate has been changed as
follows:

5.Effective time: (Production):

December, 1993 (including SMF).

3. Tr ouble shooting L5 errors that occur when making reduced-size copies (70%)

1.Model name: Z-88 /SF-2010

2.General: When the lens magnification is set at 70%, the lens shaft holder comes into contact with

the side panel of the 2/3 mirror, and an L5 error (lens motor lock) sometimes occurs
when the lens is unable to return from 70% to 100%. To alleviate this problem, the
shape of the lens shaft holder has been changed.
