Printer Features
Paper-out Detection
If the paper-out sensor detects a paper out, the printer automatically enters a pause
condition after feeding or printing several lines. When a paper-out is detected, load
new paper properly and set the printer ready to print by pressing the PAUSE button.
Auto
Tear-off
When the release lever is set to one of the tractor positions, paper advances to the tear-
off position automatically, if the input buffer is empty and paper is at the top-of-form
position (as long as the printer receives no additional data after receiving a form feed).
If it receives new data, the printer reverse feeds paper to its original position and
starts printing. This function can be disabled in the default setting mode.
Buffer Full Printing
The printer stores received data in the input data buffer, and prints it when it
encounters a print command (CR) or when the buffer becomes full.
Thermal Protection
When the thermistor detects that printhead temperature exceeds
180”
F
(82”
C), the
printer stops printing to protect the printhead from overheating.
High-Duty Printing
When the +35 V monitor circuit determines that printing duty is too heavy for the
power supply because the line voltage has dropped, the printer stops printing until
the voltage recovers.
It then continues printing the rest of the document at halfspeed.
Sheet Loading and Sheet Ejection
The release lever engages or disengages the tractor unit drive mechanism. The lever’s
operation provides improved paper-handling functions:

Automatic cut-sheet loading without the cut-sheet feeder
Move the release lever to the FRICTION position and load a sheet using the paper
guide (top or optional front). A few seconds later, the sheet is automatically loaded
to the top-of-form position, and the printer becomes ready to print.
. Automatic cut-sheet loading and ejection with the cut-sheet feeder
Move the release lever to the FRICTION position, and load a stack of paper into the
cut-sheet feeder hopper. Pressing PAPER FEED loads the sheet to the top-of-form
