ADJ 5.6 DADF Document Detection
Purpose
Preliminary-Enable document size sensing.
Check
dC927 Size Detection Automatic Correction
Perform this adjustment when the following operation is conducted:
ï Replacing of the DADF ASSY.
ï When an error is detected after replacing Registration Roll, Feed Roll, and Retard Roll.
ï When an error is found on the size detection.
Scan three sheets of document continuously in the DADF. Comparing the Slow Scan length
detected in the DADF with the standard value, correct the NVM data automatically. The NVM
data subject to the correction is "Document Slow Scan size correction value in Non CVT Mode"
(Chain Link No.710-003).
Documents for scanning differ depending on each market as below.
FX, XE/AP: A4LEF (Slow scan length accuracy (210.0mm ±0.7mm))
XC: 8.5"x11"LEF (Slow scan length accuracy (215.9mm ±0.7mm))
Adjustment
1. Enter dC 527.
2. Set three documents to be transported in the DADF.
*Document sizes to be transported differ depending on each market.
FX, XE/AP: A4LEF (Slow scan length accuracy (210.0mm ±0.7mm))
XC: 8.5"x11"LEF (Slow scan length accuracy (215.9mm ±0.7mm))
3. When the [Enter] button is pressed, DADF starts pulling in the document and calculate the
correction value. At this point, the [Entering] message appears.
4. The corresponding NVM data is updated and PSW screen indicates that the process has
been completed
Or, if this process becomes NG, the NVM data is not updated and the message telling that
NG has occurred appears on the screen.
5. Pressing the [Exit] button completes the servicing.
Specification on Result Confirmation
The following result can be checked in the NVM Read after the process completes.
<Restrictions to Note>
ï Once this process has started, it cannot be stopped (interrupted) half-way until it com-
pletes irrespective of success or failure.
ï This process does not allow the fourth sheet onwards to be pulled in when documents of
four or more sheets are set in the DADF.
NOTE: If the result is NG after the adjustment, perform the process again.
