Cut Length Adjustment; 5 Mm (For 420 To 1189 Mm - Ricoh FW780 Service Manual

7.5 CUT LENGTH ADJUSTMENT

The cut length adjustment should be done when the roll feeder is installed to
correct cutting errors. The cut error correction data is determined in the factory
without the copier installed. The cut length varies depending on the copier on
which it is installed and/or paper type used. If required, adjust the cut length as
follows:
NOTE: The cut length should be measured 10 minutes or later after copying
because the fusing unit dries the paper and reduces its length
temporarily.
7.5.1 Preset Cut : Adjustment standards: 3 mm (for length shorter than 420
mm) 5 mm (for 420 to 1189 mm)
NOTE: There are three settings of the cut length depending on the temperature
mode. They are set in the factory to match a standard paper type.
[Normal (SP#42, 45), High (SP#43, 46), Low (SP#44, 47)].
1. Make 5 copy samples of A0 lengthwise (1189) and A3 sideways (297) in the
preset cut mode.
2. Measure the difference of the length between the each copy sample and
preset cut length (1189 and 297). Then, calculate the average difference.
3. Input the average value using SP modes #42 to 47 so that the cut length is
within the adjustment standards.
Example: 1. Current SP data #42....0
Copy sample length = 297 -- 4
Set SP mode #42...4.0
2. Current SP data #42....0
Copy sample length = 297 -- 4
Set SP mode #42...+ 4.0
4. Make A0 lengthwise and A3 sideways copies using preset cut mode and
check their length.
5. Repeat steps 2 to 4 if necessary.
