PRINTING PROBLEM VERY SUDDENLY MY PRINTER HAS STARTED PRINTING BANDS OF FULL INK COLOURS ACROSS THE PAGE, ON TOP OF THE IMAGE. JUST PRINTING BLACK TEXT IS NO PROBLEM BUT ANY COLOUR PRINTING GIVES ME THE COLOUR BANDS. THIS IS CAUSING THE CARTRIDGES TO RUN OUT VERY QUICKLY. help!!!

laser unit or smps

try to change the color ink. horizontal banding (the pink or other color lines appearing means horizontal banding) when there is a problem on one of the heating element of the printer head. since almost all canon printers have head built in the inks, replacing the faulty ink will solve the problem. if not then the controller of printhead on the carriage and mainboard needs to be checked.

Checked ink cartridge's, two had dried out, still had ink in them but the exit apertures were blocked.
So new set of ink cartridges and problem fixed.
Thank you

Is the nozzle is perfect? i dont think so. But, if you print with best/photo mode is ok.

The effecds like 'banding' very often this happens when the ink is running low.

When you say 'full color' do you mean at the 'best' [i.e. most ink used] setting or the you are printing the image on a full sheet of paper?

How do your images appear when you print small, say wallet sized, single image only on the page? draft mode? Gray scale?

Check the dev unit for missing lines. Also clean the laser glass with the supplied cleaner pad - though if the problem were caused by toner on the lens, there would be gaps in ALL colours.

Check the dev units first. You can also do a stop test whilst a full colour test image is half way through printing and see if the lines are missing off the image on the PCU as well.

On some printers, probably including yours, the black ink will be taken from the reserves in your colour cartridge unless you specifically tell it to do a black and white print on each document, regardless of whether it's printing black exclusively. I wouldn't worry, the black ink in it's own cartridge can also be used for colour photos etc with no detrimental effects.

I have the same problem. Any solution?
