Overview
The sensor is designed to register off a preprinted mark on a label. The label
must have a no copy area measuring 7.8mm in the feed direction prior to the
registration mark. The registration mark is to measure 3mm in the feed direction
and 10mm across the web. The registration mark must be a solid bar. The
registration mark may be any color except yellow or green.
Setup
Place a strip of the desired printed material through the web guides on the feed
deck under the registration sensor and through the open feed roller. There must
not be any drag from the web guides or the foot on the registration sensor. If
there is drag from the web guides open them equal distance so the web tracks
down the center of the feed deck. If the foot on the sensor contacts the web
make sure the “Locating Clamp Screw” is snug. If this doesn't correct the drag,
loosen the two “Mount Screws” that mount the sensor bracket to the upright
frame. Insert a .015" shim or 3 layers of material between the feed deck and the
“Sensor Foot”. Retighten the two “Mount Screw” and remove the spacing
material. If the foot drags on the web this will steer the web off center and not
track correctly through the feed roller.
Turn on the Finishing Station. Loosen the “Location Clamp Screw” and place
the green light beam in line with the registration mark on the label in the feed
direction. Advance the web by hand with the feed open until the green sensor
light is positioned just prior to the label registration mark. With the green light
