MODULE OVERVIEW
Chapter Issue 3, Aug 14 Technical Reference Manual 30.3
MODULE OVERVIEW
Purpose The optional Roll Height Monitor detects the height of the roll of the print
medium, if insufficient height of the print medium roll is sensed an automatic
paste dispense operation is initialized.
Elements The Roll Height Monitor consists of the following:
• Roll Height Monitor Assembly
• Voltage Regulator
Operation The Roll Height Monitor assembly is fitted to the machine replacing the front
squeegee ‘I’ bar mount. The front squeegee is fitted to the assembly in the same
way as it fits the squeegee ‘I’ bar mount. The laser light source is fitted to the
left hand leg of the assembly and the light receiver is fitted to the right hand leg.
The light source and receiver are positioned such that the line of sight between
them is in front and between 10mm - 16mm above the tip of the squeegee. As
the machine performs a print stroke to the rear, the height of the print medium
roll in front of the squeegee is monitored between 50% and 90% of the print
stroke. If the receiver acquires light from the light source a paste dispense
operation is initialized and an entry is written to the event log file. If the entry in
the event log equals or exceeds three, the tricoloured beacon displays red and
an error message ‘Insufficient Print Medium Has Been Dispensed.’ The
option to replenish the paste dispenser is given.
