User’s Manual—SNAP™ 700 Printer 39
Classification: Avery Dennison - Public
4.4 Using Pre-Printed Stock
When using pre-printed or die-cut stock, the printer must detect a sense mark on
the stock in order to print in the proper place.
The SNAP 700 printer comes with a through-hole sensor standard. The
sensor, mounted in the Sensor Module, will detect a hole or slot any location
across the width of the stock. Adjusted the sensor position to the hole or slot
to register.
The printer also comes with top reflective sensor standard. This sensor, built
into the same through-hole sensor, detects a black sense mark printed on the
top side of the stock.
The bottom reflective sensor is also standard on the SNAP 700. This sensor
is built into the through-hole sensor and will detect a black sense mark
printed on the bottom of white tape or tag stock.
Two contrast sensors are options. Both are dimensionally identical and use
a fiber-optic pickup tube mounted in the up-right frame with the tip protruding
into a slot in the left guide shaft. The contrast sensor detects most sense
marks. The color/contrast sensor detects colored and more difficult sense
marks.
The fiber-optic pickup tube is moveable and will detect sense marks across
the entire width of the supply. Refer to appendix 7 for instructions on
teaching these sensors.
4.4.1 Selecting the Sensor
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. 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.
4.4.2 Aligning the Stock to the Sensor
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
