Repeating print pattern on Phaser 6280

Hi,

Yes, taht is the reason of those paterns.

I had this issue for a LONG time too. I tried everything I could think of to fix it and then I finally found the reason. The problem was in the Magenta cartridge.  I took the cartridge apart and compared the pieces/parts to those of the old empty cartridge and discovered that they changed the design of the PCR-Cleaning roller.  The original PCR-Cleaning roller is a steel rod with a solid sponge rubber material covering all but the ends of the rod.  The new PCR-Cleaning roller has a spiral wrap of this material on the rod instead.  It kind of looks like a screw.  I replaced the spiral-wrap roller with the solid sponge rubber roller, put the cartridge back together, installed it and the repeating pattern problem went away.

It's the transfer unit or the fuser since it affects all the colors.

If the ink can be smeared, it will be the fuser.

The transfer unit would have signs of physical damage on it, so pull it out and have a look

I'm having the same problem after installing 4 new Xerox high yeild print cartridges.  I'm getting the same issure with all colors with a repeating 28mm pattern.

I purchased the replacement cartridges shortly after I bought the printer since the sales person said the printer came with only starter cartridges and would not last long.  Well the finally ran out 3 years later.  Now I install them and getting these repeating pattern.

Please help.

Scott- This is a known problem (see ETI #1288122). Install a new Print Cartridge. If necessary, get a new cartridge from Xerox under the supply, 90-day warranty.

Thanks, but I think we're well beyond simplistic answers like "replace the printer cartridge" or "use the right kind of paper" which seemed to be the only solutions offered on the links you provided.  We're on the 2nd printer cartridge (OEM I might add) that has produced this result.  The machine is 3-4 years old.  The drum has never been replaced.  We'll gladly replace it if we have any reasonable expectation that it will solve the problem, but I don't want to drop several hundred bucks to replace it if it's NOT the problem.

Hi Scott in Utah,

Thank you for using the Support Forum. Please take a look at the solutions for horizontal bands and color dots.  If none of these solutions help please consider contacting your support centre for further assistance.

We are consistently getting a faint (usually) gray pattern across the length and width of the paper (see image below).  It comes in repeating horizontal rows a little more than 1 inch apart, and each row has 9 identical marks.  The marks are, near as I can tell, grayscale.  (The attached image is adjusted to increase contrast so that the marks are more visible.)  This does not appear to be a function of the toner cartridge, as replacing the cartridge has not changed this behavior.  We also don't see any (visible) defects on the imaging drum or the fusing roller, either.  

It's bearable for in-house printing, but rather embarassing for anything that we send out.  Any info on the source/solution would be greatly appreciated.  Thanks!
