12. Buying Paper
12.1. Sourcing Paper
In order to maintain your warranty, use only paper that conforms with eXtendo
®
Paper
Specification D 684 122. Use of paper that does not conform with this specification may
adversely affect the performance of your eXtendo
®
printer and/or damage your printer.
Please note that the eXtendo
®
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 eXtendo
®
printer conforms with eXtendo
®
Paper Specification D 684
122.
12.3. Black Mark Sensor Location
The Black Mark sensors on the eXtendo
®
printers can be located in numerous positions
during manufacturing, both above and below the paper (sensing the printed side and the
paper back, respectively). Figure 13 represents X-56 and X-80 paper, and show where the
black marks should be located in order to be detected with the sensor located on the printable
(coated) side of the paper. Areas shown in dotted lines are on the back side of the paper with
the sensor below the paper. The numbers shown inside each black mark area are the Black
Mark Position numbers. Only positions 1/2 for X-56 and 3/8 for X-80 (both of each pair is
used) can be employed for a through-beam sensor. The default sensor positions are so
marked. Please note that sensor locations other than the default location are intended for
OEM applications.
In order to avoid accidental interpretation of preprinted information as the black mark, it’s
necessary to keep the area 5 mm to the left and right of the black mark edges for the entire
length of the printout free of all printing except Pantone Safety Colors with a print contrast
(PCS) value of under 15%, as measured by MacBeth RD924. The black mark itself must
have a print contrast over 80%, per DIN 66223, measured with MacBeth PCM2, Filter B. This
applied to the side of the printout where the black mark is located, regardless of whether it is
the thermal-coated side or not. The blue area shown in Fig. 13 shows this zone for the
default sensor position 6 of the X-56.
