How print position is
effected by patch reading
The ability to print at the designated print position will be effected by
patch reading, and by the amount of printed information which changes
for each document. If you encounter print position drift, it may be
necessary to change your print template using the Mode Setup
Software or change your current print position further down the page.
Following are some examples illustrating print drifting with Patch
Reading turned off and on.
Patch Reading turned off
The following illustration shows the print position when 1 to 3 half or full
print lines have been changed with Patch Reading turned off.
NOTE: A half print line consists of 6 characters; a full print line consists
of 12 characters.
Print position drifting occurs when more than 3 full print lines need to
change.

If Patch Reading is turned on, and if the print position exceeds 1 inch,
then the patch window will be forced to 4 inches. Patches must be
