the printer. Rotating the wheel clockwise (the direction labeled “Paper Out” on the wheel) will
cause paper to back out of the rear of the printer.
Note
: Under normal conditions, the Paper Wheel will not be used. Paper must be loaded with the
automatic paper load function in order to be detected properly. See
6.4.
Print Speed
Print speed is affected by many factors. First, the maximum print speed is dependent upon the
operating version of the eXtendo® version that you ordered. Even with the maximum print speed in
the firmware set to 350 mm/sec, the 12 Volt models will not exceed 130 mm/sec. Other significant
factors affecting print speed include:
Type of interface / ASCII printing vs. Graphics printing
Data transmission rate (serial)
Density settings
Dot history factor
Multi-strobe factor

Cutter Operation
The cutters used in the eXtendo® series printer are either Twincut guillotine types or rotary cutter
types, depending upon what is ordered. All types are motor driven and use internal cam action to
provide feedback as to when the cutter has returned to its home position. Twincut versions with full
and partial-cut capability can make full or partial cuts under software control. Technical
specification sheets on standard versions of the cutters themselves are available upon request from
Hengstler.
Please note that, when dealing with an eXtendo® with the Twincut guillotine cutter, the cutter
blades can be manually moved without removing the cutter cover. Simply insert a small, flat bladed
screwdriver in the screw slot located in the area circled in Fig. 12, and turn. This will manually turn
the motor, moving the blades. This is useful in clearing paper jams.
Please be sure to remove power from the printer before moving the cutter blades, and keep your
fingers clear of the blades themselves.

Partial Cut with Chute Sensor
The behavior of the eXtendo® family of printers when using the full- and partial-cut
guillotine version of the cutter is different when a partial-cut is made and the printer is
equipped with the chute sensor. With the sensor, the platen motor is locked after the
partial cut is made to make it easy to tear the remaining paper tab and to prevent vandals
from pulling the paper off the paper roll inside the printer. After approximately 30 seconds,
