go to amazon or google Canon PIXMA MP620 print head and you will get a list of suppliers

Check the Magenta cartridge, is ir empty?
Do a maintenance head cleaning (do a deep clean) - check the Magenta print head, is it still blocked.

Assuming that you are using original Canon cartridges or a brand of Compatibles that you have used before.

If print results are blurred, colors are faded or not printed correctly, the pint head nozzles are probably clogged.

Follow the procedure below to print the nozzle check pattern, check the print head nozzle condition, then clean the Print Head. You may have to do this 2 or 3 times.

If printed ruled lines are misaligned or print results are otherwise unsatisfactory, aligning the Print Head may improve print quality.

Caution Do not rinse or wipe the Print Head and ink tanks. This can cause trouble with the Print Head and ink
tanks.

Note Before performing maintenance
Open the Top Cover and make sure that all lamps on the ink tanks are lit red.
If not, see Checking the Ink Status and take an appropriate action.
Increasing the print quality in the printer driver settings may improve the print result.

hello mvn 500 your printer is a inkjet say yes please remove the your colour catridge or laser printer please change the magenta ink only because laser was a 4 colour option cyan, magenta, yellow and black

The other week I had the black print head clog up, requiring daily nozzle deep cleaning [a normal 'ocassional' maintenance function]. Thought I needed a new Print head, so anything worth a try.
I loaded up an old black cartridge [I load all my own......always have] with Isopropyl Alcohol and ran deep clean on that cartridge a couple of times, then repeat printed [6 times] a page full of the number 8 in about half inch character size, to get the alcohol through the nozzles. then Deep cleaned again 3 times, to wash it through the print head.

I reloaded the normal ink filled cartridge and ran the '8' page again till I got good black output. It has now been working without problem, daily, for over a week. Clearly if it's a Magenta only problem, the cleaning as described above would be a bit different, as the magenta is one of 4 colour cartridges.
My printer does quite a lot of work, and was bought at least a couple of years ago, being used daily for alpha numeric and photo printing work. This was the first difficulty I experienced with it.
Hope the above might help.Ken

the problem is very simple the magenta ink the cartridge is over or the head is been blocked from where the magenta ink comes out,
because red colour requires ---yellow plus magenta(pink)----to make it red.and ----dark yellow plus magenta(pink) -------- for brown colour.

Check your other colours. Anything other than a True Type Font is printed in colour shaded with black, so it sounds like you have a problem with yellow and cyan. Either the ink cartridges are out or the print heads have a blockage.
If the cartridges are not empty or v low, try sitting the print head over a folded paper kitchen towel damped with hot water for 10 minutes. Remove it and try your diagnostic again.

Take a look at the mounting point. They break very easily on this model. If not broke, try cleaning with a swab and inserting the cart again.

the colors transfer to the printhead by gravity. the felt on the inktank must make intimate contact with the stainless steel filter in the printhead. I have a pixma ip 6000D that I had to replace the printhead inside of two years three times. the bubblejet circuitry in the printhead got burned out. New heads cost from $55 to over a hundred.
