Customer Question
sp c431dn color...
sp c431dn color printer has a light line, vertical 1/3 from edge of paper on black print only. Line is lighter print, only on black or gray script or pictures. NO LINE IN COLOR PRINTS.
SO FAR I have replaced the toner and black transfer with no change. I have looked at (fuser) or heater? and can not see where the toner could be removed. strip is .5 inches long and from top to bottom of printed page.

Paper is printed and comes out upside down normally. The line is 3 3/8 inches from left side of paper, 3/16 thick, only effects black areas, like the toner was dusted off with roller that moves the paper?
When it comes out it makes the line on right side because it is ejected upside down.

Based on the length of the mark and that it is black only, it would have to be the black drum. Are you saying you need to know how to change it? Or are you able tondo that if you get the replacement?

reference first communication replaced toner. then replaced black transfer. As I understand it richo called drum a transfer unit.
Since it has been replaced already without changing problem why should I do it again?? Strike one.
Technician: Michael Hannigan, Technician replied 2 years ago

This could just be residual toner from the old one - have you tried blowing it out with compressed air?

after replace of toner and drum I ran copies - The problem did not change or get better with time. I need a richo printer guy. I think it is time to call factory service.
Technician: Michael Hannigan, Technician replied 2 years ago

You are free to do that... but if it's anything but the toner/drum, then it should clear up with time. If you think it's just not fusing to the paper but it's being laid down on the paper in the right place, then it could be the fuser roller - or more likely the fuser itself. But that should not affect only black toner.
