Mechanical Error : If the printer mechanism has a greater load due to a paper jam, etc.,
the buzzer will sound and the ERROR lamp will blink to stop the
printer mechanism.
Paper End : If the paper has run out, the paper sensor in the paper path near the
print head will detect the end of the paper roll, turn on the buzzer,
and illuminate the ERROR lamp to stop the printer mechanism. If
the paper is inserted into the paper path, the paper roll will be loaded.
(See 4.7 Inserting the Paper)
Paper Near End : If the paper is running out, the paper near end sensor will be
activated to turn on the buzzer and make the ERROR lamp blink.
Even after the paper near end is detected, a command can be used to
print by the specified number of lines. (See a description on the
command for setting the number of print lines after paper near end
detection)
Cutter Motor Lock : If the cutter position detection sensor in the cutter unit is left turned
on or off for approx. 1 second while the cutter motor is running, cutter
operation and printing will be suspended, determining it to be motor
lock.
