The Headlift Sensor allows the printer to register the platen roller on 656 printers.
Begin by rotating the platen roller until the flag is blocking the sensor. The platen
roller has been slotted to accept a regular screwdriver on the front of the machine to
assist in this operation. Adjust the pot until the high value is achieved. Then rotate
the platen roller until the flag is no longer blocking the sensor. Adjust the pot until
the low level is met. The low level is the more crucial of the two adjustments.
NOTE:
The same pot is used for both adjustments and a compromise value must be
achieved.

The Full Stacker Sensor allows the printer to detect a full load of labels in the
stacker. The stack full condition will be detected by a switch and will stop the
machine when the stacker is full. The Jam Sensor feature will detect each cut label
as it leaves the cutter. If a cut fails to occur, the machine will stop. To adjust the
jam sensor, block the sensor and adjust the pot until the high value is achieved.
Remove the block from the sensor and adjust the pot until the low level is met. The
low level is the more crucial of the two adjustments.
NOTE:
The same pot is used for both adjustments and a compromise value must be
achieved.
Stock out Adjustment
The stock out sensor has been set at the factory, however for some stocks it may be
necessary to adjust the sensor to detect stock out. With a full roll of stock loaded in
the machine, run the printer and observe how far behind the stock (to the left of the
stock) the stock out wire rod is located. This should be between 1/4 and 1/2 inch (6
to 12mm) behind the running stock. If not, loosen the set screw and rotate the wire
to the acceptable distance and re tighten.
Knife Square Adjustment
The knife has an adjustment to square the cut to the stock. To make the adjustment,
loosen the two cap screws, one on top of the knife and one below the knife, using the
3/16 ball driver in the tool kit. Move the knife in the direction desired to square the
cut and re tighten.
