Paper Feed Service Check Note: If the problem is frequent jams or paper creases, verify that the paper is neither very thick nor very thin. If necessary refer the customer to the User's Guide for specifications of acceptable papers. On 23XX-001 printers check for equal gap between the lower feed rollers and lower pinch rollers. If the gap is smaller on the left, install Shim Kit, P/N 1368067. If the paper does not stop in the correct location, refer to the "Paper Empty Sensor Service Check" on page 2-26 and the "Top of Forms Problem Service Check" on page 2-39. FRU / Symptom 1 Auto Sheet Feeder 2 Gear Train Action If the Auto Sheet Feeder is installed, remove it. Enter the Setup Menu and reset "ASF" to off. Verify that the machine works correctly without the ASF installed. If the printer fails only with the Auto Sheet Feeder installed, refer to the "Auto Sheet Feeder (ASF) Service Check" on page 2-15. Remove all paper from the machine. Press Form Feed several times and examine all rotating parts to find the problem. For better visibility, remove the covers and reconnect the operator panel to the sub logic board. The upper and lower feed rollers and the upper and lower pinch rollers should all be clean and in good condition, and should all rotate during Form Feed. To turn the gear train manually on a 23XX-002 or 23XX-003, turn the right end of the lower feed roller shaft with a 6 mm wrench. Diagnostic Information 2-27
