Label Printing on C284 - Toner usage difference from Plain Paper to Thickness 3

Wondering if anyone knows the ration of toner usage on plain paper compared to the toner usage for Thickness 3. I am printing label stock and the toner does not fuse unless I use Thickness 3. But I am going through massive toner.
Any help?

 

Better u try to print in normal quality in thickness 4 . If same thing happenes paper of label is not good try different paper label is printed in thickness 4

 

I will give that a try, thank you for the suggestion.

 

Unfortunately there is no Thickness 4 on the C284e:
Plain, Single Side, Thin, Special Paper, Thick 1, 1+, 2, 3, Letterhead, Colored, Recycled, User Paper 1, 2, 3, 4, 5, 6.
No Thickness 4

 

Okay, Thickness 4 is only on the bypass tray. You can't really put a ream of labels on the bypass tray.
