4048-1xx Paper jam error indication during POST FRU Stack control flags Photo sensor Photo sensors (paper path) Action If the exit sensor flag is not resting within the paper exit sensor during POST, the printer indicates Remove Paper/Standard Bin. Make sure the flag is operating freely and correctly. Replace the photo sensor and/or the stack control flag as necessary. Make sure the sensors are working properly. A stuck or incorrectly installed sensor causes this error. The operator panel indicates 200 Paper Jam, 201 Paper Jam, 202 Paper Jam, or 23x Paper Jam. For a 200 or 201 message, look under the cartridge. A 201 is posted if the paper stops between the input sensor under the cartridge and the exit sensor at the fuser. A 202 indicates a jam in the rear door. Errors 231, 235, 237, and 238 indicate jams in the duplex. If the printer functions correctly in the simplex, but posts these errors in duplex, check the sensor cable for continuity and replace the cable or sensor(s) as necessary. Paper picks during POST and/or continuously FRU Paper feed assembly Paper feed solenoid Action Check the pick mechanism for wear. The solenoid releases the shaft of the D-roll, allowing it to engage with a gear on the main drive. There is a step in the plastic part of the shaft that rests against the solenoid arm. This error occurs if the step is worn or damaged so the solenoid cannot stop the rotation. Replace the paper feed assembly if necessary. Make sure the spring on the solenoid is properly installed. If the spring is improperly installed or missing, the pick roller will continuously pick paper. Replace the solenoid as necessary. 2-46 Service Manual
