Adjustment procedure
1. Load legal (for USA version) or A4 (for GBR version) size paper to the first cassette.
2. Place the Muratec Test Chart No. 2003-01 on the FBS.

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. Enter Machine Parameter mode. (Press <Setting>, <*>, <0>, <0>)
6. Adjust so that the setting of Machine Parameter 017 meets the specification.
If length A is shorter than the standard, increase value.
If length A is longer than the standard, decrease value.
