Meaning/Description
0
This buffer gives the engine's general response to the current action.
0. Odd parity.
1. 1= The engine has an error condition; printing is disabled. The engine is in either a
warning state or a test mode state. See Status - 4 for details. Printing may be possible
depending on the mode; printing is possible if the bit indicates warming, it is not
possible if the bit indicates the printer is in a test mode.
0 = Engine is in normal operating condition.
2. 1 = The engine is in a warning state or a test mode state. Printing is not possible, see
Status - 4 for details.
0 = The engine is not in a warning or test mode state.
3. 1 = The engine is warming up and initializing or is ready for toner patch and gamma
table data exchange. Printing is not possible at this time, see Status - 33 for details.
0 = Engine is finished warming up and initializing.
4. 1 = Because of a jam or misprint, the image data must be resent. See Status - 6 for
details.
0 = No print data re-transmit request.
5. 1 = The engine is printing.
0 = The engine is in a standby mode.
6. 1 = The NPRINT signal will start the printing action. NPRINT is the command sent by
the image processor to the print engine control board for one print. This starts the
printing process. NPRINT is not allowed if a jam has occurred.
0 = The engine cannot print because the engine is warming up, an error has occurred
or the engine is in test mode.
7. 1 = A communication error has occurred.
0 = There is no communication error.
meaning of each bit.
0. 1: Odd parity (in this case 1, other times it could be 0).
1. 0: The engine is in a normal condition.
2. 1: The engine is in a warning state or a test mode. See Status 4 for details. Printing
may be possible, depending on whether the printing is in a warning state (printing
possible) or a test mode state (printing not possible).
3. 1: The engine is also warming up and initializing or is ready for toner patch and gamma
table data exchange. Printing is not possible, see Status - 33 for details.
4. 0: There is no print data re-transmit request.
5. 0: The printer is in a standby condition.
6. 0: The engine cannot print because the it is warming up and initializing, or the there is
an error condition, or the printer is in a test mode (diagnostics).
7. 0: There is no communication error.
The print engine is operating normally (ready to transmit and receive instructions).
The engine is in either a warning state or a test mode state. See Status - 4 for details.
The engine is also warming up and initializing or is ready for toner patch and gamma
table data exchange.
There is no print data re-transmit request.
The printer is in standby condition.
The NPRINT signal will start the printing action.
There is no communication error.
