hi, i have a laser jet pro 4100dn and i am on my 2nd MICR toner. bought from Troy. i have printed out a check and some places are still grainy. then i run my finger over the check area and it continues to smudge. i print on regular paper with MICR toner and it doesn't smudge. so do i conclude that the check stock is the issue? i am at my wits end and this has been an issue for me for over 2 months. i cannot keep doing this and having vendor checks not be able to be deposited. thank you.
