ABDUL QUDDUS Posted May 12, 2010 Report Share Posted May 12, 2010 Hi In one of our 340 I am facing minalignment of yallow beam in sub scanning. when i try to alignment all three color beams, cyan and megenta are on each other but yallow beam is quit far from cyan and megenta. I am facing this problem only in sub scanning. The main scanning is very good. Any help would be appreciated Regards ABDUL QUDDUS Quote Link to comment Share on other sites More sharing options...
Kevbo37 Posted May 13, 2010 Report Share Posted May 13, 2010 How many widths of the line is it from the cyan and magenta? There is only a small amount of adjustment available in the software. Did this happen suddenly or has the laser unit been serviced? Quote Link to comment Share on other sites More sharing options...
ABDUL QUDDUS Posted May 13, 2010 Author Report Share Posted May 13, 2010 Hi This is a recently recived refurbish one machine from UK. The space (width) from cyan and megenta line till yellow line is equal to two lines. Thanks for reply ABDUL QUDDUS Quote Link to comment Share on other sites More sharing options...
Christina Rose Posted May 14, 2010 Report Share Posted May 14, 2010 what is happening with prints? are you getting some yellow shadows at edges? Quote Link to comment Share on other sites More sharing options...
Kevbo37 Posted May 14, 2010 Report Share Posted May 14, 2010 Go to the setup and maintenance menu and enter in password 7777 go to menu 0546/printer maintenance/home position adjustment. In the subscanning section of the B laser increase the number (0-7) to move the line down on the paper or decrease the number to move the line up on the page. print a grid and check the alignment. If you cannot change that number enough then you must do the opposite to the R and G numbers. Keep the relationship between the R and G the same as you change both the same amount. After you have aligned all the subscanning lines then you must go through the main scanning rought adjustment procedure again to re-center the image on the paper. Please write down the numbers on the home postion page so that if everything gets messed up you can always go back to the start. If you had sent this laser to National Laser Company for repair it would have worked perfectly right out of the box. Good Luck, Kevin Waller National Laser Co.
