Adjustments / Maintenance Users Manual Model 686 / 686 HT
Stacker Adjustments
The stacker has four adjustments that can be made without a tool to accommodate
different types and widths of stock.
Stock Length Adjustment
Loosen the two thumbscrews 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). Retighten.
Stock Width Adjustment
Loosen the two thumbscrews behind the stacker uprights and adjust the stacker
uprights to the desired stock width position. Retighten.
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. Retighten.
Stacker Full Adjustment
The sensor on the inboard stack upright is used to stop the printer when the stack is
full. A thumbscrew adjustment is provided to set the stack height.
Warning: Some stock materials cannot be stacked to the full height of the
stacker because of excessive weight.

Sensor Identification:
Stock Out
A micro switch located on the back of the stock unwind will detect and stop the
printer when the stock core is lifted because the stock is consumed.
Hole / Slot Index Registration
The stock hole / slot registration is via an optical sensor used in conjunction with an
LED located in the stock funnel which allows the printer to register to pre-punched
or preprinted stock.
Reflective Index Registration
The same optical sensor that is used for stock hole / slot registration, allows the
printer to register to preprinted stock by detecting a black mark when the LED is
turned off via the format.
Ink Out
An optical sensor located near the ink unwind arbor allows the printer to monitor the
availability of ink.
