Bright And Dark Banding On Prints Frontier 340E

[Stone Ji]

Hi,

I now account with a problem when print the pure colour photos.When I print out photos with a big part of pure color such as a big blue sky,there will be some bright and dark bands appear on the sky part in the direction of paper transport;

 

And the day after, when I try to print out the same photo, the bright and dark banding disappear!All is OK in the first 5 minutes, we thought the problem had been solved.But around another 5 minutes later, the banding was appear again!

 

It was always ok in the first five minutes of printing,but got the banding after a short time later. I don't know what's the trouble with my frontier 340E.

 

Someone could help me!

Thank you.

Kind regards

I have the same problem in my Frontier LP2000. I opened the paper unit, I cleaned the dust inside, but the problem still exist. The technician said to me not to open the polygon unit, maybe is full of dust too. Did you solve this problem in your Frontier?
