Before Preparing Document
IMPORTANT
The DC-616 automatically compensates for image drift, one of the common problems on
digital printers. It detects the image drift caused on each page by reading REG mark with
built-in CCD scanner and adjusts the cut / slit / crease position accordingly.
To use this function, each document must have REG mark printed on them. Please refer to
the following instructions for specifi cations and position of REG mark.
1. Specifi cations
REG mark consists of two straight and
perpendicular lines.
Line length : 5 mm or more / each
Line thickness: 0.4 mm or more / each
When there are scratches or stains in the printing range of the REG mark, the position may
not be corrected.
When the read side of the document is rough and glossy, the CCD scanner may not be able
to read REG mark and barcode. (The document may diffusely refl ect light.)
The illustration below shows the best
position to print the REG mark.
