3.9 Printer Cover Sensors
3.9.1 Cover Open Sensor
• The sensor detects opening/closing of the front cover. When the cover open is detected,
while printing, the printer releases the print platen immediately and stops the carriage
movements. The printer goes offline automatically. The printer is in the recovery error state
and the error LED blinks.
The printer goes online by closing the front cover. Even if the front cover is closed, the error
LED blinks. The printer can recover by sending an error recovery command. If the printer
continues printing, it starts printing the beginning of the line it was printing when the front
cover was opened. In this case, printing position may shift; therefore, it is recommended to
initialize the printer and resend the print data.
3.9.2 Opening/Closing the Front Cover
• The cover can be opened by pulling a hook on the left of the cover toward you. When you
close the cover, push the cover backward.
• When the cover open is detected by the cover open sensor, while printing, the printer
releases the print platen and stops carriage movements. If the front cover is opened during
printing, data lines are cut. Be sure not to open the front cover.
3.10 Print Buffer-full Printing
When subsequent data is received after the printer processes one line of data in the print buffer,
the printer automatically prints the processed line and feeds the paper by one line.
3.11 Paper Jam Removal
To remove jammed paper from the print head area, open the front cover.
NOTES: • Since the print head becomes very hot just after printing, remove jammed paper only
after the print head cools sufficiently.
• The carriage moves to the specified position after the printer is reset. Do not touch
the carriage.
