Reset Codes
The most common transmitted error codes are:
Uppercase “R”
This code is sent every time the printer is turned ‘On’, signaling a hardware reset.
Uppercase “T”
This code signals a software reset. A software reset is made by sending the command sequence to the
printer or by performing a reset using the front panel keys.
Lowercase “v”
There is an input buffer overflow situation, caused when an overflow of data is sent to the printer.
