Can anyone suggest what causes these lines across the page?
Is a new toner cartridge likely to fix this?
Edit: Line separation is 62.5mm
Edit 2: Thank you to everyone who replied. I've ordered a new toner cartridge and will update this if that solves the problem ๐ซก
Final update: A new toner cartridge fixed it. It's now printing perfectly! Thank you.
What I do is the redneck method, which is take the stupid thing outside, don a respirator, and blast it with the air compressor. Your solution is probably significantly more environmentally friendly, though.
