CL3500N Maintenance?

[andpur12]

I bought the CL3500N just over a year ago (just past warranty!) and used it only sparingly. I would say I printed no more than 1000 pages so far. All displays are normal. It does not indicate out of toners or a need to change any components. but there's problems with printing.

Black is not coming out correctly. On the right and left side of the page, black is printed but not as sharp as usual. And it slowly fades into the middle. There’s not black prints in the middle of the page. Colors come out uniform but not sharp. And there’s a 1/2 inch streak about 2.5 inches from the right side.

Is this problem common to this machine? Is it the PCU I need to replace?

Thx.

It's likely to be the black PCU, the drum units are not so good on these models.
I would also check the colour PCU as well by printing off the colour demo page as well.

Replace Black PCU and this is the beginning...Very soon you will replace the CMY PCU. Bad luck for you and all of us,unfortunatelly!!
