3.4.3 Aligning the Sensor to the Stock

Select the sensor one of two ways. First, the sensor type can be selected as part of
the format (see the PCMate Platinum manual or the PCL manual for details).
Second, override the format sensor using the Virtual Control Panel (see section
8.0). If the Format sensor type is selected, the printer will use the sensor
specified in the format. If one of the other sensor types is selected, the printer
will use that sensor and ignore the selection in the format.
The printer does not know if the optional sensors are
installed. If one of these sensors is selected but not
installed, the printer will not operate properly.
In order to work properly, the stock must be aligned to the sensor before starting
to print. To do this, close one or both print-head rollers (depending on whether
the label is single- or double-sided) and use the Auxiliary Feed knob until the
sense mark is just to the left of the sensor. Then rotate the ink rewind arbors to
take up any slack and press the Start Button.
This alignment must be done anytime the printer would
normally create a leader. This will happen after most
errors. Do not align the stock after a normal stop or a
stacker full.
The SNAP700 has two sensors that operate together to provide the hole, top
reflective, and bottom reflective sensor functions. These sensors are small
black rectangular plastic modules that move across the web by turning the
adjusting knob. One sensor is above the web and the other is below the web.
There are two "dimples" in the sensor body that mark the sense position.
When using a hole sensor mark, align the inboard dimple with the hole in the
web. When using either top or bottom reflective sense mark, align the mid-
point between the dimples with the printed mark.
If the sensor is not properly aligned when printing is started, the printer will
stop with the Supply light flashing. Pressing the Voice button will give an
error message that will identify the type of sensor. For example, if the format
calls for a hole sense mark (or the front Panel Sensor Override is set to Hole),
the message will be "Hole Sensor Calibration Error". This error will also
appear in the Virtual Front Panel.
In this mode, the Supply light will flash at a rate that is proportional to the
