If you execute maintenance mode function 55 this initializes the white level data for the CIS.
Also may be worth checking the laser glass
Possibly a fault on the carriage pcb. It has a sensor for detecting the edge of the page.
Thanks all the resonses. I reattended today and threw some powder on the drum blade. Also changed the dev bias voltage to -600. So far so good
I did run the developer initialization to calibrate it. All was lrinting perfectly while i was there. I did not supply the parts for this job was given them by the boss. Just fitting what i was...

From memory if Lexmark machines detect a problem with th operator panel it will beep 5 times at boot up. If it is not doing this could be a board issue.
Yeah thats the one underneath the carriage pcb. They can be a pain in the ass and tbh i have never had that sensor fail on that model.
Possible comtamination on the encoder carriage movement or paper feed. Also possibly paper width sensor on the carriage PCB.
Have you checked the left and right cartridge locks and lock lever slides? Also the alignment of the main drive might be causing it.
What drums were replaced? ES series oki machines use the same drums and toners as the regular Mc range except the chips r different. That could possibly cause the issue.
Have you tried updating the firaw are? Also have you tried a different brand of paper. Lastly check there is decent airflow for the machine to vent heat especially the rhs of the machine.
The symptom theengel is the machine says there is no paper in the tray even though there is. Had several calls like that.
Would look at the color dev engagement sensor on the main drive and the solenoid as well. May be sticking.
I usually put a piece of electrical tape between the magnet and arm. Solenoid is louder but never sticks again
Have you tried different paper stock? Fresh ream or different brand.
Try updating the firmware.
Have you checked the laser unit for dirt?
If its brown its most likely a problem with the transfer belt cleaning assy. Check the cleaning blade and replace if needed.
