6.6.1 PAPER FEED

Pick-up roller drive is controlled by the pick-up solenoid if paper gets fed from the
paper tray unit. The on/off of the solenoid is controlled by the general output port or
the external output port. The machine feeds the paper based on the operation of
the manual sensor and the main motor.
The machine shows the following jam conditions when paper feed troubles occur.
Item Description
• Paper does not enter the unit due to a paper misfeed after a page was
Jam0
picked up.
• Paper entered, but did not get to the feed sensor in a certain time due to
slip, etc after a page was picked up.
• A page was picked up, but the feed sensor is not on. Jam0 shows if the
feed sensor is still not on after a certain time after the feed sensors tries
again. This means that the leading edge of the paper doesn't pass the
feed sensor within a certain time.
• The feed sensor does not turn on even though the paper reaches the
feed sensor. This means that the leading edge of the paper already
passed the feed sensor or that the sensor is faulty.
• The trailing edge of the paper does not pass the feed sensor within
Jam1
certain time after the leading edge of the paper passes the feed sensor.
(During this time the feed sensor cannot be Off)
• The paper does not reach the exit sensor within certain time after the
leading edge of the paper passes the feed sensor. (The exit sensor
cannot be On during this time)
• There is already paper between the feed sensor and the exit sensor.
• The trailing edge of the paper does not pass the exit sensor within
Jam2
certain time after the trailing edge of the paper passes the feed sensor.
