This C450 has intermittent color registration, not on every copy but gets worse the more copies run (28# paper). New IU's, belt changed. Looking for any other opinions before I pull the board box and change out the motor.

Are you getting any Error Codes? Run Gradation Test patterns. Also Check belt drive assembly.

Check if it register any P-codes. Respects for still having one running. Switch it on make some coffee read your emails may be it ready... send a print job scratch your balls for a while and wait in front of the machine for the print to come out.

Is the transfer roller rotating freely. How many clicks on the machine?
