Hi, if the color alignment failed when you tried it, you'll probably need to have a service technician troubleshoot and diagnose the problem. It could be one of many things:
- One of the PCUs
- The image transfer belt
- The laser unit
- One of the MUSIC sensors
If it's only one color that's out of alignment and you don't want to call a technician, you could try replacing the PCU for that color to see if that makes a difference.
