Table 42. Numerical printer messages (continued) Message Description Action 13.01.00. or 13.03.00 JAM IN TRAY X For help press or 13.03.00 PAPER JAM OPEN INPUT TRAYS THEN OPEN AND CLOSE TOP COVER A page is jammed in tray X. A 13.01.00 error message indicates that the media did not arrive at the pre-feed sensor (PS102) within the specified time. A 13.03.00 error message indicates that the media did not arrive at the top-of-page sensor (PS103) within the specified time. NOTE: The 13.01.00 error can also be caused by the failure of the paper-level sensor (PS107). If this sensor fails, the lifter motor does not rotate to lift the paper tray plate. This error can also be caused when the printer attempts to pickup media from a tray that is empty, but the paper-out sensing mechanism for that tray has failed and the printer senses that the tray appear to be loaded. 1. Press the HELP ( ) button for detailed information about clearing the jam. 2. Press the UP ARROW ( ) button and the DOWN ARROW ( ) button to step through the instructions. 3. Check that the paper-out sensor in the specified tray is functioning properly. 4. Clean the pickup roller. If it is worn or damaged, replace it. 5. Clean the feed and separation rollers. If they are worn or damaged, replace them (always replace both rollers at the same time). 6. Verify that the pre-feed sensor (PS102) is installed correctly. See "Correctly install the paper-feed assembly sensor flag" on page 197. 7. Open and close the specified tray while watching the control-panel display. A short delay should occur between when the tray closes and the tray-size message appears on the control-panel display. If there is no delay and you do not hear the tray-lift motor lift the tray plate into place, replace the tray's stack position sensor (PS107, PS802, or SR2). See "Printer switches and sensors" on page 336, "500-sheet feeder switches, sensors, solenoids, and PCAs" on page 340, or "1,500-sheet feeder switches, sensors, solenoids, and PCAs" on page 343. 8. Replace the tray X pickup solenoid. 9. Replace the tray 1 paper-pickup assembly. See "Tray 1 paper-pickup assembly" on page 192. 10. Replace the paper-feed assembly. See "Paper feed assembly" on page 195. 276 Troubleshooting Q2431-90912
