8. ERROR HANDLING
This section describes some typical errors that could be detected on the control board at power on
(initialization) or during printer operation.
Error status can be known from the nERROR and nPEOUT signals. (The following describes errors that are
identified by LED lights.)
In the event of an error, the BUSY (DTR), PE, FAULT, SELECT, or some other signals may be activated as
well as the ERROR and/or PEOUT signals described in the following table. The BUSY (DTR) signal
depends on jumper (J6) setting, however.
