Hi guys,
at the beginning after finding b/w blur print out, i perform the following steps trying to solve the problem.
1) at first i change a drum ( took from other unit) -> remain blur
2) replace another black bottle toner-> remain blur
3) replace dv tank ( took from other unit) -> Ok
but after existing K toner bottle finish, and replace with new one, it start blur again.
anyone encounter this issue before?
appreciate if you could share with me if you have similar problem.
