30 Chapter 1 Troubleshooting control panel messages
EN
The printer is NOT receiving data back from the density sensor (PS14).
PS14 is located in the bottom of the imaging drum drawer. During
calibration routines, a series of images are written on the imaging drum
and the densitometer measures the density of the image (i.e. the
amount of toner that is placed into the drum). These measurements
provide the feedback to ensure image quality is consistent throughout
the life of the consumable.
1 Verify that the densitometer is clean; perform the toner density
sensor cleaning procedure in the online user guide that came with
the printer.
2 Inspect the density sensor wiring harness for damage. The harness
runs from the density sensor through the left-side upper control arm
of the imaging drum drawer to J1010 of the DC controller PCB.
Verify that the cable is firmly seated into the J1010 of the DC
controller PCB.
3 If the error persists, replace the density sensor assembly.
Optional equipment is not recognized.
• Turn the printer off and on to reset the printer.
