CHAPTER 2 FUNCTIONS & OPERATION
4. Staple
Detection
In this unit, a staple detection mechanism is
employed which detects the jumping up of
stapled documents. This mechanism is designed
not to detect the staple itself, but to detect the
jumping up of the stapled documents, and to stop
the feeding. As such, it prevents stapled
documents from being torn apart.
Fig. 2-307 shows a stapled document
jumping up due to the pick-up roller.

Fig. 2-308 shows the configuration of the
staple detection.
The staple detection consists of staple LEDs
and a staple photo-sensor, arranged on both
sides of the document pick-up opening. If there is
no staple in the documents, the light emitted from
the LEDs is received by the photo-sensor. If the
stapled documents jump up, the light gets
blocked and the documents are found to be
stapled, resulting in stopping the feeding.
The five staple LEDs are mounted on the
staple LED PCB. The staple photo-sensor has
five sensors that correspond to the five LEDs on
the staple LED PCB, and is directly mounted on
the document tray control PCB (10_SUB).

Note:
Because the documents do not jump up
under the following conditions, the staple
detection sensor will not work:
• When there are two or more stapled
places.
• When the staple is not positoned at a
corner.
• When the documents are smaller than
A5.
Document curl must be 3 mm or less in
height and the documents cannot be
creased.
It is possible to change the level of
detection accuracy with the user mode.
