3.10 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 Roll Paper Cover Open Lever
When the roll paper cover open lever is pulled, the roll paper cover opens. When the roll paper cover
is closed, the internal hook is latched.
NOTES: 1. Be sure to use the roll paper cover open lever to open the roll paper cover.
2. Do not open the roll paper cover during printing.
3. Do not open the roll paper cover during the auto-cutting operation; doing so may damage
the printing mechanism.
3.12 Roll Paper Cover Open Sensor
The roll paper cover open sensor monitors the printer cover. When the sensor detects a roll paper
cover open during printing, the printer enters an error state, stops printing and goes offline
automatically. The printer recovers to online when the roll paper cover is closed.
When automatic error recovery is selected:
If the printer detects a roll paper cover open during printing, the error LED flashes. When the roll
paper cover is closed, the error LED goes off, and the printer initializes itself and starts printing from
the beginning of the line being printed immediately before the roll paper cover was opened.
When possible error recovery is selected:
When the roll paper cover is closed, the printer recovers upon reception of
DLE ENQ 2
. If the roll
paper cover is open during standby, the printer goes offline. When the roll paper cover is closed, the
printer recovers to online.
NOTE: The status reported by the paper sensors remains the same as that reported immediately
before the cover was opened.
When the paper-end stop is selected with the memory switch Msw8-5: (Default)
When the roll paper cover is open, the printer recognizes a paper-end; when the roll paper cover is
closed, the printer recognizes a paper presence.
