General Troubleshooting Paper is picked and moved through either the simplex or duplex paper path to determine the paper trailing edge arrival time at each paper path sensor. R values have alternate definitions or are unused depending on the pick tray and if simplex or duplex path was selected. Duplex Paper Trail Edge Times R# Definition 7 Exit Trailing Edge Interval (us) Typical Value (8400) 8 Duplex Deskew Trailing Edge Interval (us) 9 Duplex Preheat Trailing Edge Interval (us) 10 Duplex Strip Trailing Edge Interval (us) 11 Duplex Exit Trailing Edge Interval (us) Typical Value (8500/ 8550/8560) Actions Reports the interval from the time the engine software is commanded to start the duple pick process until the Exit sensor deactivates. Reports the interval from the time the engine software is commanded to start the transfix process until the Deskew sensor deactivates (part way through the paper transfix motion). Reports the interval from the time the engine software is commanded to start the transfix process until the Preheat sensor deactivates. (part way through the paper transfix motion). Reports the interval from the time the engine software is commanded to start the exit process until the Strip sensor deactivates (part way through the paper exit motion). Reports the interval from the time the engine software is commanded to start the duplex pick process until the Exit sensor deactivates. Phaser 8400/8500/8550/8560 Color Printer Service Manual 4-29
