PIXMA MP150 Will not print correct colours from camera chip

As long as the cartridge that is telling the printer I'm empty is in the printer, you can't go on. I did reset all my colour cartridges in my printer, because I only print in black. Still now and then a cartridge is telling it is empty. I think the printer still wants to mix colours in the black. Lucky me, I can reset my cartridges all the time.
I'm not sure you can do the same on the canon. Try to get a chip resetter that is sold on all refill stores.

it will be very hard to clean the print head manually you have to bring it to a service center canon pixma ink

Try to do some cleaning and alignment. You can access that by going to your printing preferences and clicking on the maintennance tab. Or, pull up the document that you want to print. Click File, then click print. Click on Printing Preferences and click on the Maintennance tab. The tab would have different levels of cleaning.

When you select print, select the printer properties box next to the name of the printer. In here there should be a quality or resolution setting. Increase this setting for a better image.Canon (Skywell and G&G are good also) Should give great results, but some "alternatives" are very bad in colour.
Hope this Helps GM

There are may be the cartridges are empty kindly install new one.

you go to the printer settings, before giving the print command. there you select "print in gray scale". Your problem is over.

You can only refill those cartridges if you do it before the ink is empty. After that you need a new cartridge or a chip resetter to reset the chip on the cartridge so it will work again.

You need a NEW Print head, the cartridge may also cause this problem, however most likely the
problem is from the printhead(it's the thing the ink tanks fit into inside printer). I hope this helps, good luck. You could also run a deep cleaning and use real Canon inks and that would help as well.

before printing check the quality printing in printing preferrences to change it to best or normal.
