Calibrate The Substrate - HP 54 Basic Cutter User Manual

The pinch rollers are lowered or raised simultaneously by means of the pinch roller lever arm, located on the
right-hand side of the cutter. The pinch rollers must be lifted to allow vinyl loading, during which the substrate is
fed from the rear of the cutter to the front. When raised, the pinch rollers can be moved manually to the left or
the right along the pinch roller shaft.
CAUTION: Always make sure that the pinch rollers are fully raised before sliding them to the left or right.
CAUTION: Always hold the assembly at the side of the pinch roller to move it from left to right. Do not
reposition the pinch roller by holding the assembly at the rear of the machine.
The pinch rollers must be positioned correctly and lowered onto the substrate before an automatic load
sequence is initiated. Make sure all the pinch rollers are positioned above a drive sleeve. The outer left pinch
roller should be positioned in one of the detents (click positions), situated under a white triangular label. The
outer right pinch roller should be positioned somewhere over the long drive sleeve. Click positions are located at
the edges of the sleeve (area marked with a white triangular label).
CAUTION: Always leave the pinch rollers in the up position when the cutter is not in use. Leaving the pinch
rollers in the down position for a long time will create a flat spot on the pinch rollers, which will seriously degrade
tracking performance and cutting quality.
NOTE: When the pinch rollers are raised during a job, the cutter will immediately stop and move the carriage to
the right side.

Calibrate the substrate

Substrate calibration ensures that the sensor is able to recognize the HP barcode and the markers. OPOS is
calibrated at the factory to work on a wide range of substrates. However, certain substrates—such as those with
a high gloss, or translucents—may not work with the default settings. Before working with such materials,
perform a substrate calibration. This alters OPOS's sensitivity so that it can read the markers with greater
reliability.
Print a calibration plot on the substrate that will be used, by clicking Setup > Printer Cutter Calibration Chart in
the RIP software. Be sure to use the same ink that will be used when creating the registration markers.
