Troubleshooting complete.
Check the position and cleanliness of the Drum Temperature Sensor. Is the Sensor posi-
tioned properly with no interference?

Clean or correctly position the Sensor.
Check the Transfix Load is working properly. The Transfix Arms should move during transfix
(see Figure 4).
1. Remove the Control Panel (REP 1.5).
2. Remove the Lower Inner Duplex Guide (REP 3.2).
3. Close the Front Door. While printing a test print page, look through the gap on each side

down. Replace the Load Arms (REP 2.21) if no movement is visible.
NOTE: Some customer actions will cause ink to be removed from the image such as scratch
or abrading the surface of the image or applying/removing tape or sticky notes. This is
expected behavior. No further service actions can correct this behavior.
