Only Prints in Magenta

Either the ink you are using is not going to give the color you want, or you have print heads that are blocked.

enough ink b ut not printing at all - blank paper on every time despite noise as if printing

Do you have photo cyan or photo magenta installed? your machine does not use these inks, and will give wrong colors. You need plain magenta and plain cyan. If you are using generic inks, they could have bad colors too.

If you have installed photo cyan or photo magenta, your prints will be off color. This machine only uses plain cyan and plain magenta.

As a guess you have the color ink cartridges in the wrong places. Take them out and run a whole bunch of head cleaning routines. I'd expect the wrong colors for a while until the incorrect ink has been flushed out.

Check your manual or setup guide for the actual order . Usually black-cyan-magenta-yellow

Sounds like you got a defective cartridge, it happens once in a while. On some Canons, you hold the resume button for 5 seconds and it will ignore the error, not sure on your model printer.

1. Get compressed air
2. Run Printhead under HOT water, do not worry about contacts getting slightly wet.

3. Blow compressed air with straw attachment into screens where the cartridge nozzle sits on printhead. then let it sit and dry.

4. reinstall print test page

5. if this fails open paint/photoshop and print a page of the color that is not printing correctly. rinse and repeat until colors flow freely.

I have several ip4300s and I have yet to give up the ghost on a printer with a clog ujsing this method.

if your cartridges are new one then do this, reinstall printer driver and check in the printer driver features that you have selected print in black and colour option

I had the same problem. Try cleaning the print heads. They tend to clog. Remove the cartridges, then remove the print head. Tilted slightly, it comes out easily. Run very warm to hot water over the print heads until they all run clear. Use a turkey baster to apply strong pressure to each head until it runs clear. Blow off the excess water with mouth or blow dryer. Insert into the printer and proceed to print. If that doesn't solve it, you might have a bad cartridge, but there isn't much that can go wrong with the cartridge. I have an ip4200 and an MP830. They have the same print heads and same cartridges. I have cleaned each twice and they work like new.

Well, first off, are the alignment, and nozzle check sheets looking good? If not, then work on that. If so, then we have a problem. Try creating a test sheet in Word. Make red, yellow blue & black text and see if anything else prints wrong. Get back to me!
