3. Registration (Manual)

Registration adjustment is normally per-
formed in automatic mode [All]. This manual
adjustment is a mode that performs fine ad-
justment of the result of the automatic adjust-
ment. Note that it does not reduce variations
in the registration position.
 Adjustment sheet
You can use a sheet that is printed any pat-
tern to be judged a gap of position of the
leading and trailing edges. Therefore you
can use the test sheet; TKM-0271, adjust-
ment sheet; 6Y3-6001 that is used for the
automatic adjustment, or others.
 Operation Procedure
In this section, it is described a case that
adjustment value is known ready.
1) Clean feed path, rollers, and scanning
glass.
2) Place a single adjustment sheet in center
and printed side should be set to adjust-
ment side.
Make sure to set the document guides so
they are fit with the adjustment sheet to
prevent skews.
3) Select the [Edit] button.
4) As for the value to adjust, the amount of
additional change is added to the value
previously set by the automatic adjustment.
For example, add [-1.0] mm to "Front: Top"
if you want to make the reading start of the
leading edge 1mm earlier on the front side,
or add [1.0] if you want to subtract 1mm.
