Bit 2
Mechanical errors include home position, carriage sensor and slip ejection errors.
Bits 2 and 3
If these errors occur due to paper jams or the like, it is possible to recover by correcting the cause of the
error and executing DLE ENQ n (n=1-2). If an error due to a circuit failure (e. g. broken wire) occurs, it is
impossible to recover.
Bit 6
If the print head temperature becomes high, bit 6 is transmitted until the print head temperature drops
sufficiently. The printer automatically recovers from this error.
