CHAPTER 7 PICK-UP / FEEDING SYSTEM
The presence of paper or a jam is checked in terms of the presence/absence of paper at a
specific sensor at such times as programmed in advance.
The copier is capable of remembering the number of copies remaining to be made and the
selected copying mode so that the copy count or the copying mode need not be set once again if it
has been opened and closed for jam removal.
If any of the sensors detects paper when the power is turned on or the door is closed, the copier
will identify the condition as being a jam.
If a jam occurs during continuous copying, on the other hand, the copier continues to make
copies on paper that has already been picked up.
The pre-cleaning paper sensor (PS71) is a reflecting type paper sensor, and it detects paper on
the photosensitive drum to prevent copy paper from rushing into the photosensitive drum cleaner
(occurring often when double feeding takes place).
