Error Processing

Printer Operation When an Error Occurs

The printer executes the following operations upon detecting an error:
All mechanical operations stop
Goes off-line (if DIP switch 1-8 is set to OFF)
The ERROR LED blinks.
Error recovery
The TM-U200D recovers from an error state when you turn off the power, correct the error, and
then turn the power back on.

Data Receive Error

If one of the following errors occurs, the printer prints "?" or ignores the data, depending on the
setting of DIP switch 1-1:
Parity error
Framing error
Overrun error.

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 data and feeds the paper one line. When the
printer detects no paper, it does not print until new roll paper is loaded.

Detectors and Printing

When the printer detects a paper near-end, it stops or continues printing, depending on the ESC
c 4 command setting. The roll paper detector always halts printing when there is no paper.
