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 5.1 Loading Paper.

5.4 Print Speed

Print speed is affected by many factors. First, the maximum print speed is dependent upon the
operating version of the eXtendo® XF version that you ordered. Even with the maximum print speed
in the firmware set to 250 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
• Baud rate settings when using RS232
• Density settings
•
Dot history factor
•
Multi-strobe factor (usually not needed)

5.5 Cutter Operation

The cutter used in the eXtendo® XF series printer is a Twincut guillotine type.
It is 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® XF 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 manually moving the cutter blades, and
keep your fingers clear of the blades themselves.

5.5.1 Partial Cut with Chute Sensor

The behavior of the eXtendo® XF family of printers when using the full- and partial-cut
guillotine version of the cutter is different when a partial-cut is made. 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
