The “out” position lowers the printhead to the platen so that the printer is ready to print. The
“in” position raises the printhead off the platen. The printer is shipped with the printhead in
the “in” raised position; it must be lowered to the “out” “ready to print position” for use.
Leaving the printhead in contact with the platen for a long period of time without paper under
the printhead may cause a temporary indentation in the platen, which can result in initial
feeding difficulties. If this occurs, simply push the Printhead Position Control in to raise the
printhead, insert paper, and then pull the Printhead Position Control out while the motor is
running.
7.3. Paper Advance Wheel
The eXtendo
®
family of printers is equipped with a Paper Advance Wheel to make it simple to
manually advance paper when needed. (See Fig. 5.) Rotating this wheel counterclockwise
(the direction labeled “Paper In” on the wheel) will draw paper in from the paper supply at the
rear of 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.
7.4. 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 and 10-36 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
•
Burn time correction setting
•
Multi-strobe factor
•
Limited print speed specified at time of ordering
7.5. 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.
