Initializing the document stopper
The projection on the upper document feed roller needs to be set (initialized)
to the optimum position to operate the document stopper properly.
The fax 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 pickup jams and
document too long errors.
A “pickup jam” means the document edge sensor cannot detect the leading
edge of the document within 15 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 39.4" (1000 mm) of document have been transmitted.
Document jam processing
If a document jam occurs, the fax stops the document read motor and ADF
operations, displays the error, and the Error lamp flashes in red.
For a pickup 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.
Image data stored in memory when memory transmission, or delayed
transmission, or sequential broadcasting, is erased from memory at the point
when the jam is detected.
