AL-2041 SIMULATION, TROUBLE CODES 10 - 20
50 18 Memory reverse position
adjustment in duplex copy
(AL-2041 only)
[Function]
When this simulation is executed, the current set correction value is displayed.
Enter the correction value and press [START] key to save the entered correction value. (Correc-
tion value range; 1 – 99, Default: 50)
For S-D mode front surface print, reverse memory copy operation is performed from the rear
edge of documents.
When, therefore, the print position adjustment of output images is required, adjust as follows:
In the reverse memory coping, when the document scan is made in the arrow direction, the out-
put image is printed from the rear edge of scan image.
When, therefore, the print lead edge is shifted, set the reference chart so that the reference
position is on the rear edge, and use this simulation to adjust the set value so that the print lead
edge is matched.
Since printing is made from the image data most lately stored in memory to the lead edge data
from the print start position, the image lead edge adjustment is made by changing the end data
position stored in memory by the set value of this simulation.
Since it is performed by changing the scan end position, the image position adjustment is made
by changing the scan end position and the end data stored in memory.
The adjustment modes can be selected by pressing [Exposure mode selector] key.
* The initial value of duplex setting is "1to2/Long Edge" for the duplex model, or "2to1" for the
simplex model.
[Operation]
The operation is similar to simulation 46-01.
19 Duplex copy rear edge void
adjustment (AL-2041 only)
[Function]
Used to adjust the rear edge void amount in duplex copy.
When this simulation is executed, the current set value is displayed in 2 digits. (Center value:
50.) The adjustment modes can be selected by pressing [Exposure mode selector] key.
(Adjustment range: 1 – 99)
Enter the adjustment value with [ ] [ ] key and press [START] key to save the set value and
make a copy. (The paper information is cleared for every copy.)
When the set value is increased by 1, the void amount is increased by about 0.1mm.
* The initial value for duplex setting is "1to2/Short Edge" for the OC/SPF setting.
[Operation]
The operation is similar to simulation 46-01.
