Conditions When the copy image area

(image loss, void area) is not

within the specified range.

∗

Necessary condition

1) The copy magnification ratio is within the specified range.

2) The copy distortion is within the specified range.

Work content

1) Make a test chart as shown below.

2) Enter the SIM 50-10 mode.

3) Set the test chart made in procedure 1) on the document table.

4) Make a copy and measure the left and the right void areas.

(Measure the distance from the left/right edge to the image lead

edge.)

If the void area is not within the specified range, perform the

following procdure.

Standard value: 2.0

+1.0

−0.5

5) Select the left void area adjustment with the copy picture quality

mode select key.

(The currently set adjustment value is displayed on the copy quan-

6) Change the set value and press the start button.

(The adjustment value is stored and a copy is made.)

When the set value is increased, the void area is increased.

When the set value is decreased, the void are is decreased.

When the void area is changed by 1, the void are is changed by

0.1 mm.

Repeat procedurs 4) ∼ 6) until the left void are is within the

specified range.

7) Select the right void area adjustment with the copy picture quality

mode select key.

(The currently set adjustment value is displayed on the copy quan-

tity display.)

Adjust the right void area in the same manner as the left void area

adjustment.

∗

Troubles caused by improper work

1) If the void area is less than the specified level, the transfer roller,

the fusing roller, the separation pawl, and the paper transport

section are dirtied with toner.

As a result, print paper is dirtied and paper jams are generated.
