Status | Explanation | |
Byte 4 | ||
| ||
|
| |
00 | No duplex error. No problem was reported to the engine by the | |
| duplex system card. | |
|
| |
01 | The leading edge of the sheet of paper never arrived at the input | |
| sensor. | |
|
| |
02 | The duplex option system board never received media notification | |
| from the printer. | |
|
| |
03 | The trailing edge of the sheet of paper never cleared the input | |
| sensor. | |
|
| |
04 | The leading edge of the sheet of paper never arrived at the exit | |
| sensor. | |
| Note: This error is the most common due to the long length of the | |
| paper path between the input sensor and the exit sensor. | |
|
| |
05 | The duplex logic thinks a sheet of paper is feeding to the duplex | |
| unit due to a sensor malfunction in the paper path when in fact the | |
| printer has not sent a command to send a sheet of paper to the | |
| duplex unit. | |
|
| |
06 | The exit sensor detected a sheet of paper too early. | |
|
| |
07 | The sheet of paper’s trailing edge did not clear the exit sensor in | |
| the desired length of time. | |
|
| |
08 | The feed motor experienced a complete motor stall. | |
|
| |
0E | The D.C. motor is under speed. The motor never reached the | |
| correct operating speed. | |
|
| |
13 | There is paper left in the duplex option. Paper was sensed during | |
| the homing operation during POST. | |
|
| |
15 | There is paper left in the duplex option. Paper was sensed during | |
| the DC motor diagnostic test during POST. | |
|
| |
18 | The D.C. motor experienced an acceleration error. | |
|
| |
3D | There is paper left in the duplex option. Paper was sensed during | |
| IR clear during POST. | |
