CHAPTER 4: FIRST PAPER FEED SECTION
[ 4 - 22 ]
Adjustment
1. Upper Limit Sensor Position Adjustment
Adjustment
(1) Remove papers from the paper feed tray, and slide the paper-feed pressure lever to “NORMAL”.
(2) Start Test Mode No. 681 (paper feed tray upper limit positioning) to raise the paper feed tray and bring it to
a complete stop.
(3) Check that the gap between the pickup roller and the paper feed tray is between 1.5 mm to 2.5 mm.
(4) If the gap is out of the specified range, rotate the upper limit adjusting shaft by inserting a flat head screw
drive through the paper feed cover hole. Rotating the shaft will move the position of the upper limit sensor
up or down.
*
If Test mode No.740 (paper limit position selection) is selected to “CARD” or “ SPECIAL”, make sure to
select the test mode to “AUTO” or “NORMAL” before making the adjustment (RZ3 series).
*
Rotating the upper limit adjusting shaft in clockwise direction lowers the upper limit sensor assembly and
increases the gap between the pickup roller and paper feed tray.
Symptoms
If the upper limit sensor is positioned too high, the paper feed pressure increases too much and multiple sheets
feeding may occur. On the other hand, if the sensor is positioned too low, the paper feed pressure reduces too
much and no paper feed may occur.
