manager Posted April 13, 2011 Report Share Posted April 13, 2011 I have a sudden problem on 203x305mm print size on my Frontier 340. There is an iregular line, perpendicular to transport paper, on every picture in the same place. Not sure what could it be. I also noticed that the line is more intense on darker images, so not noticeable on white test jpg print. Please help! P.S. the pictures looks awful because i enhanced contrast so you can see it better.. Quote Link to comment Share on other sites More sharing options...
manager Posted April 13, 2011 Author Report Share Posted April 13, 2011 I forgot to mention that in the magazine compartment there is a dusty area as I have a problem with the loading door. Should it be dust in laser area? Should I disassemble the printer till I reach laser and clean that area? Is it easy to get there? Quote Link to comment Share on other sites More sharing options...

manager Posted April 14, 2011 Author Report Share Posted April 14, 2011 This is a detail scan. Wave amplitude vary a little on every print. Just look at the line, the rest are not important as I processed image to be more evident. Quote Link to comment Share on other sites More sharing options...
manager Posted April 16, 2011 Author Report Share Posted April 16, 2011 I cleaned laser optics and the line is still there. I have another type of lines on the edge of 20x30cm print. Quote Link to comment Share on other sites More sharing options...
Christina Rose Posted April 17, 2011 Report Share Posted April 17, 2011 primary cause could be a moving dust in between the exposure area. (Exposing path). Quote Link to comment Share on other sites More sharing options...
