PC-D320/PC-D340/FAX-L400 Chapter 2: Technical Reference
Initializing the document stopper
The projection on the middle document feed ass'y needs to be set (initialized)
to the optimum position to operate the document stopper properly.
NOTE
The machine performs initialization when the power is turned on, and after a
document is ejected.
Document jam detection
The document edge sensor detects such document jams as pick-up jams and
document too long errors.
A "pick-up jam" means the document edge sensor cannot detect the leading
edge of the document within 10 seconds after document feeding begins.
A "document too long error" means that the document edge sensor cannot
detect the trailing edge of the document, even after the stepping pulses for
feeding more than 14" (356 mm) of document have been transmitted.
Document jam processing
If a document jam occurs, the machine stops the document feed motor and
ADF operations and displays the error.
For a pick-up jam, "CHECK DOCUMENT" is displayed. For document too
long error, "DOCUMENT TOO LONG" is displayed.
If the document is being copied when a document jam occurs, the image data
scanned in and stored in memory are erased for all pages, and print operations
are stopped.
