I put new ink cartriges in my cannon s400 this morning, it is afternoon now and it will not print in colour, It will not print the test either, it was working before I changed the cartriges, can you please help me. thank you Vera Silverwood

This sounds like the chip on the ink cartrige, try cleaning the chip or replacing the red magenta ink. How a printer works, information from the Dynamic Link Libary is sent to the printer driver, this information is where to print on the paper and what colour to print, ie turning the ink jets on and off, the depth of colour comes from each ink by mixing the inks from the information in the photo or text. All ink problems are usually from ink faults, miss printing comes from driver information. Phill

Try unplugging printer from the power and connecting it back.

Try also extracting all toners and putting toners back.

reinstall the ink cartridge and then try

Jast go to print option. Then Mantainance. Then try to print a nozzale. If all the colour comes out properly ( with out dot or misline), your cartrige head is goog for print. If not, your printer cartrige head is block. To reque from the problem follow the proces:
1. Unpluge colour cartrige.
2. Try to clean the cartrige head with soft cloth and amonia gentaly.
3. Try to out the ink through the head nozzale pore by using shaking or gentaly swape by soft tissue.
4. Now put the cratrige head upon a soft tissue. ( ink will comes out). If not, repit stage 1-4 until ink come out.
Thank you

Hello. You can refill the existing cartridge without a problem. Other brand cartridges will not work as they are all programmed only to use DELL model cartridges.
To Refill the cartridge you simply need to pull the label off, Drill the Air holes out, test what colour is behind the hole by sticking a toothpick into it and inject the correct colour.
If the cartridge leaks from the print head then the cartridge has been overfilled and you need to **** out ink (half ml at a time) until the dripping stops.
The only issue with this is that the printer may not accept a cartridge that it thinks is empty, and even though you fill it, the in-built counter in the cartridge will still read "0"
Some models will print with a empty cartridge, constantly reminding you that it is empty. if you simply ignore or click continue you can keep on printing, but some models will not print at all if it thinks the cartridge is empty.
I hope this helps Regards GM

For the Canon Pixma MP220, I kept getting a message saying "Col Ink Vol Unknown" after refilling and replacing a cartridge. After reading some of the other responses it appears as though Canon cartridges contain internal chips that prevent you from using them after they have been refilled. However, I tried a few things and this is what worked for me.

1. Insert your refilled Canon cartridge like normal, close the lid.
2. The Error message "Col Ink Vol Unknown" should still appear.
3. Use the "Menu" button to scroll to "Maintenance" (press "Menu" 8 times to find it), then press "OK" to conduct a "Nozzle Check" and a coloured test will print out.
4. The Error message will still appear but you will be able to print using colour AND with black and white. For some silly reason the Canon Pixma MP220 won't print using black and white if there is no coloured ink...

Hope this helps!

make sure the bottom of the print cartridge is clean. If not tak etape and then tape it off if theres too much ink leakin on the cartridge.

Take a dish- put damp tissue in it- if it can a one of the alchohol based cleaning tissue fine.
Stand the cart init for 10 minutes.
with a similar tissue give the contact sheet a wipe. and if it is flush to the bodty see if it has some give.
Reinstall and try

the color cartrige is defective. replace only with original cartriges

Purch. a new cart see if that works.
