P6021cdn Code 7404

[copiman]

I have a Kyocera P6021cdn that has a code 7404. I just started to look at it. Someone else has been servicing it. Here is what I know from the history.

Current meter is B/W 1,076 Color 2,763

In this order:

1.Cyan toner replaced.

2.Code 7404; 0002853 Removed developer (Y) and cleaned

3.Replaced Developer Unit (Y)

4.Code 7403 Removed Cyan Developer unit and cleaned

5.Cyan/Magenta colors off Color Cal. with code 7403; 0003363 Cleaned dev units installed Y and K toner


I did not do these calls but I have to fix it. Any ideas? Are these dev codes an issue for this model? First time on this model.

I just noticed that I posted in copier instead of printer section. I have now posted this in the printer section.
