Printouts Are Dirty with Splattered Toner
This might be because an inappropriate paper is used or the amount of toner in the cartridges is low. Try the following remedies.
Are you using appropriate paper?
Does dirtying occur when used in a low-humidity environment? (MF543dw / MF455dw / MF453dw / MF452dw / MF451dw / MF449dw / MF448dw / MF445dw)
Change the <Low Humidity Mode> setting. The effect is stronger with <Mode 2> than <Mode 1>. Try starting with <Mode 1>.
When set to <Low Humidity Mode>, print density might be light or uneven if the machine is used in a high-humidity environment.

Is the amount remaining in the toner cartridge low?
Regardless of the amount displayed for the toner cartridge, it might have reached the end of its service life due to the machine's operating environment or deterioration of the inside of the toner cartridge. Replace the toner cartridge.
