Meaning/Description
0
This status shows the hardware control circuit error condition. It shows details when
Status - 0 Bit 1, Status - 1 Bit 1, and Status - 2 Bit 1 are ON.
0. Odd parity.
1. 1 = Not used.
0 = Always set to 0.
2. 1 = Not used.
0 = Always set to 0.
3. 1 = Not used.
0 = Always set to 0.
4. 1 = EEPROM check error has occurred.
0 = EEPROM is normal.
5. 1 = SRAM check error has occurred.
0 = SRAM is normal.
6. 1 = Program ROM checksum error has occurred.
0 = Program ROM is normal
7. 1 = A communication error has occurred.
0 = There is no communication error.
The print engine control board EEPROM is operating normally.
The print engine control board S-RAM is operating normally.
The print engine control board program ROM checksum failed.
There is no communication error.
This status shows the warning or test mode details when Status - 0 bit 2 is 1.
0. Odd parity.
1. 1 = Media warning. See Status-32 for details.
0 = No media waring.
2. 1 = Toner warning. See Status-31 for details.
0 = No toner warning.
3. 1 = Engine is in test mode and can't print. See Status-17 for details.
0 = The printer is not in test mode.
4. 1 = Consumables life warning. Maximum density warning occurs when the engine has
toner density at maximum levels. This is an indication of a possible component failure
or possible low toner condition. See Status-44 for details.
0 = No consumables life warning.
5. 1 = SRAM check error has occurred.
0 = SRAM is normal.
6. 1 = Program ROM checksum error has occurred.
0 = Program ROM is normal
7. 1 = A communication error has occurred.
0 = There is no communication error.
There is no paper/media warning.
There is no toner warning.
The print engine is in a test mode state, it cannot print.
The printer is not in a consumables life warning mode.
There is no maximum density warning.
There is no communication error.
Paper/media warning mode; for example, the printer may have less then 30 sheets in
the media tray.
There is no toner warning.
The printer is not in a test state.
The print engine has consumables life warning information. See Status - 44 for details.
There is no communication error.
