A single press on each switch will shift the original stop position by 0.5
mm.
When the correct position is attained (after switch operation), press the
push switch SW2.
- The original will be delivered, and the new setting will be stored in
memory.

Holding down the push switch will not cause more than a single shift.
EX
If the copy paper stops 12 mm from the copyboard glass,
Close the DADF slowly leaving the copy paper on the copyboard glass.
To shift the stop position 1 mm to the left, the following is true:
1 0.5 (adjustment interval) = 2
Hence, press the push switch SW4 twice, and press the push switch SW2.
- The copy paper will be delivered, and new setting will be stored in memory.
4.3.1.7 Stream Reading Speed Adjustment
0013-3708
1) Place the test chart in the original pickup tray, and make a copy at a 100%
reproduction ratio.
2) Put the copy and chart together, and compare the length of the image
in feed direction, making sure that dimension a is as indicated. If not, go
to the next step.

3) Make the following selections: FEEDER>ADJUST>LA-SPEED; then,
change the setting to make adjustments.
-To make the image on the copy longer, decrease the setting (so that the
stream reading speed will be decreased).
-To make the image on the copy shorter, increase the setting (so that the
stream reading speed will be increased).
