12. Buying Paper

12.1. Sourcing Paper

In order to maintain your warranty, use only paper that conforms with XPM 80™ Paper
Specification D 689 112. Use of paper that does not conform with this specification may
adversely affect the performance of your XPM 80™ printer and/or damage your printer.
Please note that the XPM 80™ can use either roll or fanfold paper. When using fanfold
paper, care must be taken to configure the printer, black mark, and positioning so that the cut
always occurs after the fanfold bend, not on it or before it. Failure to do so will cause cutting
problems and will likely increase paper jams.

12.2. Converting Paper

Thermal paper is usually purchased through paper converters. These companies buy large,
jumbo rolls of specific paper types from the few true paper manufacturers in the world and
then cut it and roll it to your specifications. You may elect to have preprinting or black marks
added at this time, as well. Please make sure that any paper a converter wishes to supply
you for use with your XPM 80™ printer conforms with XPM 80™ Paper Specification D 689
112.

12.3. Black Mark Sensor Location

The Black Mark sensor (which also functions as a "paper present" sensor) on the XPM 80™
printers can be located in numerous positions during manufacturing. Figure 8 shows where
the black marks should be located in order to be detected when a reflex sensor is used. The
default (standard) sensor positions are so marked.
The XPM 80™ printer is designed to allow for numerous Paper Entrance/Black Mark sensor
locations during manufacturing (The location of this sensor cannot be changed once the
printer is built). Also, two different sensor types can be used. The most common is the reflex
or reflective sensor, where the light source and detector are located on a single chip.
Basically, the light strikes the white paper surface and reflects back into the sensor. If enough
light reflects to activate the sensor, the printer reports that paper is present. If there is not
enough light reflected, the printer assumes that this area is black, meaning the printer is on a
black mark or the printer is out of paper. Black marks must be located on the back (non-
coated) side of the thermal paper. There are seven (7) different possible positions for this
sensor. The positions of these sensors are detailed in Figure 8 (Please note that sensor
position 1 is not usable). The default (standard) positions are so marked. Please note that
sensor locations other than the default location are intended for OEM applications.
The XPM 80™ can also use a through-beam sensor. This type of sensor has a separate light
source and detector. The light is transmitted across the paper path into a prism, which
redirects it back across the paper path into the detector. When the light is blocked and
cannot reach the detector, the printer reports that paper is present. When the light does
reach the sensor, the printer concludes that there is no paper present.
