Multifunction: CX820, CX825, CX827, CX860, XC6152, XC6153, XC8155, XC8160 and XC8163

Issue Description:

Whenever you replace supplies inside the printer, you may notice excessive toner dust, usually of mixed colors (i.e., purple or brown), on the Yellow Imaging Unit.


The existence of toner dust in itself, particularly that of individual colors (Yellow, Magenta, or Cyan) inside the printer, is considered normal (as described in

However, mixed colored toner dust (i.e., purple or brown) could be a sign of waster toner leaking from the Image Transfer Unit (ITU), especially if its concentration is seen only on the yellow imaging unit or below the right-hand side of the ITU.

Should you find the level of dusting prohibitive, please contact Lexmark Technical Support to set up printer service.
