AL-2030/2040CS/2050CS SIMULATION, TROUBLE CODES 10 - 25
50 06 Copy lead edge position
adjustment (SPF/RSPF)
[Function]
Used to adjust the SPF/RSPF copy lead edge.
When the adjustment value of the document scan position adjustment is increased by 1, the
scan start timing is advanced by 0.1mm.
The print result is shifted to the opposite direction of the scan start position.
The adjustment mode can be changed by pressing [Exposure mode selector] key (or [ ] [ ]
key for the AL-2050CS). (Adjustment range: 1 – 99, Default: 50)
When scanning a back surface of document, the mode must be changed to operate the SPF/
RSPF by pressing [2-SIDED COPY] key.
∗ When there is no document in the SPF/RSPF, copy is inhibited.
∗ When paper is discharged, the shifter is operated.
[Operation]
The operation is similar to simulation 46-01.
10 Center offset adjustment [Function]
Used to adjust the center offset position of copy images on copy paper and that in scanning
document.
When this simulation is executed, the current set value is displayed.
Enter the adjustment value and press [START] key to save the setting and make a copy. (When
the set value is changed by 1, the center is shifted by 0.1mm.)
When the adjustment value is increased, the center is shifted to right. When decreased, the
center is shifted to left.
The modes can be selected by pressing [Exposure mode selector] key (or [ ] [ ] key for the
AL-2050CS).
When the set value is changed largely, the area outside the shading area may be scanned to
cause black streaks on the edges. When the SPF/RSPF is used, select the mode for use of the
SPF/RSPF by [2-SIDED COPY] key.
(*): Support for the installation models. For non-installation models, skip.
(**): For Simplex models, skip.
* When printing with the manual paper feed tray, use paper of the letter size.
* In the 2nd print center offset adjustment, print is made forcibly as 1to2/Short Edge from OC
regardless of duplex setting.
* When paper is discharged, the shifter is operated.
[Operation]
The operation is similar to simulation 46-01.
