feed direction and the host machine's scanner system:
1) Place the Test Chart in the machine, and make a copy.
2) Check the right angle of the image in relation to the leading edge of the
output (i.e., angle A).
3) Loosen the 2 knurled screws found at the front of the right hinge unit.
4) Bend over the edge of the rubber cover [2] found at the rear of the right

hinge unit, and loosen the fixing nut [3]; make adjustments using the bolt
with a hex hole [4].
- if A>B (less than 90 deg), turn the bolt clockwise.
- if A<B (90 deg or more), turn the bolt counterclockwise.
5) After adjustment, tighten the nut to fix the bolt with a hex hole [3] in place.
6) Place the Test Chart in the machine once again, and make a copy; then,
check to see that the angle is a right angle.
If the following image appears after adjusting the right angle (i.e., if paper
moves askew), go to the next adjustment to remove the skew (registration
roller). In principle, the foregoing adjustment should correct the angle.
