Appendix D

Error Codes

The error codes that may be transmitted by the Printer are described here.

Lowercase "c"

The Printer received a data byte from the host that contains a framing error due to noise.

Lowercase "v"

Input buffer overflow.

Uppercase "I"

An invalid command sequence was sent to the Printer. The Printer did not understand the command sequence and therefore terminated the command interpreter.

Uppercase "R"

This code is sent every time the Printer is turned on. It signals that there was a hardware reset.

Uppercase "T"

This code signals that there was a software reset. A software reset results from sending the <SOH># command sequence to the Printer or by doing a front panel reset.

BELL HEX “07”

This is usually returned on a corrupt image download, or if you try to load an image that is already installed in the module.

Lowercase “e”

The memory module won’t clear. Retry after a <STX> W command.
