Situation

In firmware revisions A.02.09 or higher, the paper advance calibration algorithm was

improved. In order to optimize its performance, modify the mark encoder so that the

reference for the paper advance error compensation is more accurate.

Solution

A line or a notch is included in the middle of the mark encoder. In units that are in the range

of serial numbers listed above, follow this procedure to add a line on the mark encoder.
Please, verify that your unit is within the serial number ranges that are quoted above. The

units produced after these ranges will have a notch in the middle of the mark encoder, so the

line will not be required.

Procedure to Install the Line on the Mark Encoder

After installing firmware revision A.02.09 or higher:

1 SwitchĆoff the device.
2 Remove the media.
