Stacker Adjustments
The stacker has four adjustments which can be made without a tool to accommodate
different types of stocks.
Stock Length Adjustment
Loosen the two thumb screws at the base of the stacker uprights and slide the
uprights to a position that allows the cut tag or label to hang over the last belt roller
approximately 1/4" (6mm). Re tighten.
Stock Width Adjustment
Loosen the two thumb screws behind the stacker uprights and adjust the stacker
upright nearest to the operator to the desired stock width position. Re tighten.
Stacker Angle Adjustment
Loosen the lever located on the side of the stacker assemble nearest the operator and
adjust the angle of the stacker with a few cut labels in the stacker so that there is a
slight gap under the last label as it hangs over the last belt drive roller. Re tighten.
Stacker Full Adjustment
The sensor on the inboard stack up right is used to stop the printer when the stack is
full. A thumb screw adjustment is provided to set the stack height. Warning, some
stock materials can not be stacked to the full height of the stacker because of
excessive weight.
Stock Feed Adjustment
When changing stock type, the stock feed should be readjusted. This is important to
reduce any slip for too light an adjustment and reduce excessive roller wear for too
tight an adjustment. To adjust, loosen the two top set screws using the 5/64 Allen
key in the kit. With the new stock in the drive roller, fully close the stock feed lever
(rotate fully counter-clockwise). Tighten both set screws until there is slight pressure
on the stock. Run the one inch pull format and adjust the set screws an equal amount
based on the results. If the one inch label measures less than one inch, tighten
(clockwise) each screw slightly and repeat the measurement. It the one inch label
exceeds one inch, loosen (counter-clockwise) the tension on both set screws equally.
As a final check for stock feed balance between in board and outboard, the inboard
edge of the stock should be 31/32" (24.6mm) from the main vertical support plate of
the printer. To move the stock inboard, away from the operator, loosen the inboard
set screw slightly. This can be done while running the unit. To move the stock
outboard, toward the operator, loosen the outboard set screw slightly.
