Measurement
1) Set the A3 document on ADF.
2) Scan the test chart with ADF. at 300 dpi. (Such as Scan To USB Memory)
3) Measure length of the “A” portion as shown in the drawing. If it does not satisfy the
reference value, perform adjustment as described below.
4) If length of “A” portion stays within the reference value, it is the end of measurement.
Adjustment
Set the ADF side registration
• If the measurement data is short:
=> Adjust the setting value in the positive (+) direction.
• f the measurement data is long. (When document is scanned from the front of
document (when shade is present in the left of document.))
=> Adjust the setting value in the negative (-) direction.
When a value is added in the negative (-) direction, the scan image on a PC moves to the
left. (Because the scanning start position is moved to the left.)
When a value is added in the positive (+) direction, the scan image on a PC moves to the
right. (Because the scanning start position is moved to the right.)
Note!
Be careful that direction of movement is opposite from FBS.
