Hi
I have a lexmark xs-463de with only 20k that's making dirty copy ,it alway's come from the dev unit specially from doctor blade
When i change the toner (mono component ) the prob solved for about 1000 copy and come back..
I change the dev unit 4 or 5 time already
A new drum was installed at 17k
Any suggestion will be appreciated
thank's
