Mechanical errors include home position, carriage sensor, and slip ejection
errors.
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 ELE ENQ n(1 ≤n ≤2). If an
error due to a circuit failure (e.g. broken wire) occurs, it is impossible to
recover.
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.
