CHAPTER 5 TROUBLESHOOTING
<EX.>
• Push Switch and Sheet-to-Sheet
Distance
Note:
If the size of the originals to be used (in
feeding length) is as follows, however,
set bit 7 of the DIP switch (DSW1) to
ON.
b. Top Pick-Up Mode
Table 5-105
Suppose that the distance L5 between the
two sheets of paper on the copyboard is 4 mm
when the push switch (SW3) on the DADF
controller PCB has been pressed once to stop
two sheets of copy paper on the copyboard
glass and when the DADF has been opened.
Close the DADF slowly without removing
the coy paper.
To decrease the sheet-to-sheet distance by
4 mm,
4 mm/0.34 (adjustment pitch) = 12.12
the push switch (SW2) should be pressed
12 times.
Press the push switch (SW2) 12 times, and
press the push switch (SW3) on the DADF
controller once to discharge the copy paper and
store the new setting in memory.
6) Perform "removing the original skew,"
adjusting the distance to the horizontal size
plate," "adjusting the original leading edge
stop position," and "adjusting the sheet-to-
sheet distance for reduced image
composition mode," turn off the copier,
and shift all bits of the DIP switch (DSW1)
to OFF.
Turn on the copier, and check to make sure
that the DADF operation is normal.
