Tilt Drive This test drives the printhead tilt mechanism through one cycle to determine if it is controllable and operating as expected. R# Definition Typical Value Actions 0 Tilt Engage Cap Position (min) MFG Only Reports the distance from the cap Home position to the tilt cam engage point. 1 Pre Standby Peak Location () 50 to 3500 Reports the distance around the tilt cam from the tilt engage position to the pre standby peak. Should be in degrees, but currently units/ scaling are unverified. 2 Pre Standby peak -5500 to Reports the pm motor following error at the pre Magnitude (pm ticks) 0 standby peak location. 3 Post Wipe Peak Location () 1000 to 5000 Reports the distance around the tilt cam from the tilt engage position to the post wipe peak. Should be in degrees, but currently units/ scaling are unverified. 4 Post Wipe peak MFG Magnitude (pm ticks) Only Reports the pm motor following error at the post wipe peak location. Tray 2, Tray 3, Tray 4, Lift Plate Drive This test raises the lift plate to verify motion and sensor operation. If the test is requested for a 525-sheet feeder that is not installed, an "Option Not Detected" message is generated. R# Definition Typical Value Actions 0 Tray Configuration MFG Only 1 Start Peak Power (watts) MFG Only 2 Slack Take-up Time MFG (sec) Only 3 Average Lift Power MFG (watts) Only Reports the tray status (present, plate not lifted, etc.). See Paper Path Status test for a description of the configuration encoding. Reports the highest peak during the first quarter of the lifting interval. Reports the interval between the initial power min (when the plate is not yet engaged), and the point where the lifting power becomes a constant. Reports the average power over the center ¾ of the lifting interval. General Troubleshooting 4-39
