REG Mark (For image shift compensation)
The DC-618 automatically compensates for image drift, one of the common problems on digital
printers. It detects the image drift caused on each page by reading a REG mark with the built-in
CCD and adjusts the cut/slit/crease position accordingly.
When using a REG mark, program the REG mark position in a JOB and set
REG Mark
to
ON
.
To use this function, each document must have a REG mark printed on them. Refer to the
following procedure for specifi cations and a position of a REG mark.
