Magenta and Yellow Density range errors

[eric_sg61]

In the event logs, I am getting 54.1400 Color plane registration sensor error and 54.1103 Yellow Density Range Error. I am also getting Magenta Density Range error.  I have tried to calibrate, change toner cartridges, and I also replaced the Density Registration Sensor and still have the same problem.  What else could be causing this issue and what else can I do to troubleshoot?

How is print quality in Y and M?

If the print is good don't worry about that error in the log.

The print quality is really light on the left then gets darker to the right
