Hey, I’m using the Brother scanNcut to cut stickers, and it worked great last year but this year on some smoothly curved lines the scan is instead seeing a bumpy line? Is there a way to fix this?

This could be one faulty sensor pixel or a speck of dirt on the scanner bar. It might be worth opening the scanner and carefully dusting the bar with a camera cleaner aerosol.

this indications that you have a problem with convergence. first try to go into customer menu...setup....convergence. and see if the convergence will adjust.. if it wont then you have a problem with the convergence cuircit boards.

This indicates a convergence problem..convergence power supply probally.. however ive seen 2 other cuicits cause this ..

To access the focus block with the screen controls, remove the 2 plugs under the speaker grille. There is a philips head screw under each plug. Remove both screws. the speaker grill is now free. Pull the bottom forward and the grille will come off. The top is just held by tabs behind the screen bezel. Be careful as there is wiring to the grille for video input 2 and the front panel controls. There is a piece of fiberboard held on by 4 screws in the center which was formerly covered by the grille. Remove the screws and the panel and the focus block is right there. Each color is labeled for both screen level and focus. Adjust the screen control of the color producing the lines until the lines just disappear.

Do you get the same line when you use the adf for other purposes?

If so, check the scanner glass just before the platen for something like white-out on it. Clean both the scanner glass and platen glass with Windex.

That is a common problem on all ADF scanners.

Good Luck
