CHAPTER 2 FUNCTIONS & OPERATION
7 Feed Error Detection
This explanation is about feed errors due to
document jams. Document jams are detected by
the front and the back registration sensors.
The front registration sensor and the back
registration sensor are located at the front and
back of the registration roller, respectively. The
front registration sensors are divided into the left
sensor (L) and the right sensor (R), and are
mounted on the front registration sensor PCB.
The back registration sensor is mounted on the
back registration sensor PCB.
1) Early reach jam (P01)
The front edge of the following document was
detected after the end of the proceeding
document is detected before the motor
finishes driving the specified length.
2) Residual jam (P02)
The end of the document is not detected even
though the document has been fed for a
specific length after the front edge was
detected.
3) Fast feed jam (P03)
The end of the document is detected before
the document has been fed for a specific
length after the front edge was detected.
When the machine is powered on or the
upper unit is opened/closed with a document left
in the machine, a removal jam (P00) occurs.

8. Special Feed Mode
This unit also supports a mechanical feed
mode to check the feed condition without using a
personal computer.
This mode should not be available to the
users.
The mechanical feed mode can be activated
by pressing the keys on the operation panel, as
follows:
If the start key is pressed while in the
mechanical feed mode, with documents in the
document tray, the machine will feed the
documents at a feed speed determined by the
SCSI ID set on the DIP switch located at the
computer connection. Images are not scanned at
this time.
When specifying the feed speed is not
required, it is possible to check the feeding state
using the "Count Only mode".
