Version 5.2 or greater:
For the new V5.2 system there will be transmissive,
reflective, non-index (continuous), and center aperture.
The center transmissive sensor is intended only for
supplies that have an aperture hole located in the
middle of the web. It is referred to as the aperture
mode. The transmissive edge sensor is used for both
die cut and edge aperture supplies. The reflective
sensor is used with center web black marks.
The aperture sensing mode is enabled when the
software selects the overhead center of web LED as
the emitter and the black mark detector located
beneath the web and directly under the LED. If the
transmissive mode is selected then the edge sensor
assembly will be used. For reflective mode the black
mark sensor assembly located under the web will be
selected. Lower DIP switches 5 and 6 control the
supply type/sensing system.

The software has the capability of identifying both the
Main Processor circuit board level and the sensor
system installed in a printer. The V5.2 software is
compatible with combinations of previous main
processor boards and sensor systems. It also
supports the new main processor board with V5.2 and
earlier sensor systems installed. Use Sendfile to save
(in flash) the code that identifies that the V5.2 sensor
hardware is installed.
Performing a Sensor Display Test
This test is performed online using SENDFILE with
version 5.0 or earlier printers.
1. To display Analog-to-Digital static values,
minimum and maximum A/D dynamic values, or
information on options, press D.
2. To see the min/max range of each of the A/D
channels, highlight each sensor output and press
Enter. SENDFILE displays the following
channels:
• Uni-cell
• Head Temp
• Head Volt:
• Dot Test
• Back EMF
• High Volt:
• Contrast
• Bi-cell
Version 5.2 or greater:
To perform a sensor test with version 5.2 or greater,
see “Sensor Setup With Version 5.2 or Greater” earlier
in this chapter.
