take out the colors and see if the black prints. if not you could need a new one.

I have the same issue with that the black won t print

The print head is probably blocked then. You may be able to get a cleaning cartrige if you look online. Failing that, it will probably need a service.

I've had the Canon i9100 since 2003 and have excellent photo printing results. In 2009 it started playing up and I'd gt some banding. More recently, black didn't want to print. It was as though the black ink in the print head got dry some days.

April 2010 - The colours started printing strange and I bought a brand new print head and installed it. Only takes a minute. Still had an issue with photo printing. Black and white was excellent but colours weren't true.

Found advice online to try cleaning the print head to print head carrier electrical contacts by rubbing them with a rubber eraser.

I did that and now I'm getting perfect colour photo prints again.

I had been thinking about buying a new A3+ printer but this is old printer is now working as good as new.

You need to change the color settings of the printer to print using color and black ink. Refer to printer help.

>>printing color page in B&W
In the print dialog box, select the properties of the printer, Here you can select whether to print in color, b&w or greyscale.

Perhaps the CMY color heads need alignment. If you have not already done so, run a head alignment from the driver maintenance section. It will print out a page containing several lines and text, and request you select the closest-aligned images. After this is done, do another image print to check for improvements.
Normally, the printer uses the black cartridge for text and the CMY inks for images (even for black on photo and specialty paper). So when you are printing normal text pages on plain paper, only the black ink is used. A good check for this would be to print a normal text page, but select photo paper in the driver to trick the printer into using the CMY inks to make a substitute black text page. If this looks ok, then you are having issues other than cartridge alignment.

I have now found the solution elsewhere in the internet: black text only prints on the Canon i560 if selct "normal paper", but not,for instance, if you have "professional photo-paper" selected.
