4227-300 FRU Action 2 Paper Feed If the paper does not feed, do the following: 3 Gear Train • Remove the ASF. • Be sure the base printer feeds paper correctly. • If it does not feed paper correctly, go to the "Paper feed service check" on page 2-21. Be sure the ASF drive gear on the inside of the printer's right frame rotates. Inspect the right side gear train for damage or debris. Remove the ASF right cover and ensure that all gears are in good condition. 4 Combination Lock Install the ASF and press FormFeed. Mechanism If the pick drive shaft does not rotate, replace the combination lock mechanism. 5 Left and Right Hoppers If the ASF pick rollers rotate but a single sheet is not picked, inspect the springs and corner separators on the left and right hoppers. 6 Pick Rollers Paper Guides Feed Rollers Make sure the paper load lever is in the correct position. Paper skew can be caused by worn, dirty, or binding pick and feed rollers. Remove the Auto Sheet Feeder, load paper, and hand cycle the feeder while observing the pick and feed rollers. If the skew problem is in the base machine, examine all feed rollers for wear. 2-14 Service Manual
