NOTICE:

All test point voltage measurements including sensor adjustments should be made on the DC scale with the black lead of the meter connected to the ground test point 22. Care should be taken to ensure that meter leads do not short against unintentional test points throughout the measurement procedures.

Desired Voltage:

> 3.50 VDC

< 0.75 VDC

The Hole / Slot Registration Sensor in conjunction with the light bar allows the printer to register to preprinted media. The low level is the more crucial of the two adjustments. Note that the same pot is used for both adjustments and a compromise value must be achieved. Begin by removing the stock from the sensor path. Measure the low voltage throughout the mechanical travel of the sensor by sliding it inboard and outboard. The voltage at all points should not vary more than 0.75VDC. If it does the sensor slide bar and or the light bar must be mechanically aligned (see Hole / Slot Index Registration Sensor Mechanical Adjustment below). Once this is achieved find the web location where the low voltage is the highest and adjust the pot until the reading is 0.75VDC or less. Now block the sensor path with the media you intend to run. The high level should be greater than 3.5VDC at all points of the sensor’s travel.

Hole / Slot Index Registration Sensor Mechanical Adjustment:

There are two areas that can be adjusted to correct the voltage readings. The upper sensor square bar may be loosened from the back of the printer and rotated. The second adjustment is to loosen the light bar mount screws and move the bar in the web direction. When the light bar screws are retightened be careful not to over tighten and brake the light bar PC board.
