Let me start out by saying live and learn 'cause I just D’oh my B&W Brother HL-2140 printer.
My toner was running low. Instead of buying replacement toner, I decided to use my office’s photocopier waste toner. Mistake 1.
During the refill, I accidentally touched the toner roll that has toner on. Mistake 2.
Had I spend time reading Brother’s website, I would have known this: “To avoid print quality problems, DO NOT touch the shaded parts shown in the illustrations.” Mistake 2a.
I then decided to clean the toner with air and sprayed the roll. Mistake 3.
Doing so, I might have exposed the the toner/drum to light and damaged the photosensitive parts. Mistake 4.
The result is that now the print quality is very bad: grey background, fuzzy image, very light letter, grainy, toner specs, and large white lines.
In your opinion, is there any possibility that I can fix my mistakes? If yes, how?
The toner came with the printer and this is the first time it needs refill.
Thank you for your time and suggestion.
