Bizhub C3350 vertical lines in the center of the printed page

Re: Bizhub C3350 vertical lines in the center of the printed page

When I've had those lines from the transfer belt many time I was able to replace just the trans belt cleaning blade (aftermarket) instead of expensive transfer belt. Especially when trans belt is no where near end of life. Unlike most of Kon/Min belts that can last 2-3 cycles these crap out early instead of reaching consumable expire count.

Sorry for the late reply, i just now got to have a closer look at the transfer belt. The culprit seems to be the tranfser belt cleaning, as many of you have already suspected. Reasons are:

1. I have printed some test documents with multiple color areas, and after that printed a document with mostly text on it. On that document the vertical lines are very clearly visible and as blackcat4866 pointed out (from a very bad quality picture), the lines are not onyl black but black, yellow and magenta. So it seems that it is not one imaging unit, but some part that affects all colors.

2. A photo of the transfer belt immediately after this print shows yellow (and other) toner residue stripes on the transfer belt in the center, but no visible residue in the outer areas. So it seems the belt surface has been cleaned, but after the cleaning there is still toner residue in the center. That looks indeed like the transfer belt cleaning is not working correctly.

Do you have any suggestions where (located in Germany) i can get one or two cleaning blades, what the part number for C3350 is or where i can search for that? Is there any manual on how to replace the cleaning blade?

Not sure how many different ways you need to be told it's the transfer belt. Anyway I suggested the cleaning blade and may have been wrong. The aftermarket blades are sold for the C35 which I thought are the same as C3350? I've never confirmed this so maybe someone can?

Here is the blade I had in mind:

Copylite - Aftermarket, Compatible, and OEM Copier Supplies and Products

Also a good rule of thumb with servicing copiers & printers: gray / green color lines or toner leaking inside machine, etc is always waste toner. If lines / toner leaking are only one color CYMK then look at that specific color drum / developer unit as the issue.

Not sure what you mean by that.

It would be helpful if someone could confirm that the cleaning blade for the C35 will work for the C3350.
