I just changed my toner on my printer and some of its pages smear. Really irritating when I’m printing 150 pages to have to go through and check that each page is not smeared. Any suggestions? I have a Brother 6200DW.
Might be a bad toner cartridge.
I had the same problem, went to Walmart got me a can of compressed air, the one we use to clean keyboards and another electronics devices, sprayed inside couple of times and the smudge disappeared, no need to replace the toner.
