DocuCutter 545
Creasing
The DocuCutter DC-545 uses an integrated Creaser to
produce a crease (or multiple creases) perpendicular to
the paper path, as determined by the program data. The
crease enables smooth, even forming of finished paper so
it may be folded easily after processing. Creasing also
permits folding of color printed documents with minimal
toner cracking or flaking.
Creasing is accomplished in the DocuCutter DC-545 with
the following components:
• A high torque DC Motor with a self-contained torque
enhancing transmission
• Long life, high-precision male and female paper
creasing surfaces
Creaser Construction
The upper and lower surfaces of the Creaser are
designed to mesh when they are pressed together. One
surface has a channel and the other surface has a ridge
that fits into the channel.
Creasing Drive
Energy is supplied to the Creaser by a high torque drive
configuration. Rotational energy is supplied by the motor,
through a self-contained gear drive, to a Drive Belt and
ultimately to the Creaser Drive Pulley. The Pulley is
directly connected to an Eccentric Shaft. When the Shaft
is driven, the eccentricity causes the upper creasing
surface to move towards the lower creasing surface, thus
creasing the paper.
Operational Status
The Camshaft activates a Photo Interrupter. The Photo
Interrupter signals the Microprocessor that the Creaser
Unit has reached the home position. The Creaser Unit is
cycled each time the DocuCutter DC-545 is powered on. If
the Microprocessor fails to receive the home position
signal, a jam is declared and the LCD indicates
CREASER LOCK.
