I have tried shaking the toner because at first it was printing un-even and fixed a bit. The black ink is a bit low but not out. I am not sure if the only solution is to buy a new toner. I also don't know how to use the settings at all. is there anyone who knows more about this printer and can help me? Also where do I even buy a cartridge for this printer?</P><P>&nbsp;</P><P>Thank you!!!&nbsp;</P> Fri, 03 Feb 2023 21:24:43 GMT printernewbie04 2023-02-03T21:24:43Z https://community.usa.canon.com/t5/Office-Printers/Canon-MF-3240-printing-horizontal-lines/m-p/404655#M18352 <P>hello,&nbsp;</P><P>I have a laser canon mf3240 printer. it has been sitting in an office for a while. it does work.
