Adjustments
Feed Roller Pressure
General
The rubber pressure roller is supported by an eccentric shaft mounted in bearings
located in vertical slots in the front and rear mounting plates of the drive module.
This roller is mounted in an extension spring controlled arm so no pressure
adjustment is required.
Sensors
Sensor Identification:
Stock Out
A micro switch located on the back of the unwind will detect when the stock core is
lifted when the stock is consumed and stop the printer.
Hole / Slot Index Registration
The 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
possible preprinted stock.
Reflective Index Registration
The same optical sensor used for hole / slot registration, allows the printer to register
to preprinted stock by detecting a black mark when the LED light is turned off via the
format.
Ink Out
Optical sensors located on each print station’s ink unwind arbor allow the printer to
monitor the availability of ink.
Roller Drop
An optical sensor on back of print station number two allows the printer to control
and register the platen roller position to perform ink save.
Feed Open
A micro switch on the back of the feed module will detect the position of the feed
module pressure knob and only allow the printer to operate with the feed pressure
knob closed.
