5.3.7 FBS zoom adjustment (Vertical)

The difference should be within ± 0.4% (1.6 mm) of the actual length of A on the test chart No.99-1.
Adjust so that the following specifications are satisfied with the length of A (400 mm) on the test chart
No.99-1.

(400 ± 0.4%)
Adjustment procedure
1. Load the A3-sized paper to the cassette.
2. Place the Muratec Test Chart No. 99-1 on the FBS.
3. Make two copies of it on the A3-sized paper with 100 % magnification.
4. Measure the length of A on the second copy to find the difference.
If length A falls outside the specified range, perform the following steps to make the adjustment.
5. Entry the Machine Parameter mode. (Press MENU, [, 0. For detail, see page 3-2.)
6. Adjust the setting of Machine Parameter B:7 to meet the specification.
If the length A is shorter than specification, increase value.
If the length A is longer than specification, decrease value.
