Question about Canon PIXMA MP780 All-In-One InkJet Printer
I'm having a problem in that certain colors are dropping out when printing, the irony being that they are not always the same one. For example, magenta wasn't printing and now after countless deep cleans, cleaning the heads and replacing cartridges that are drying out in the process, the cyan won't print.
When I print out the check pattern the color bars all look fine, including cyan but it has dropped out of the letters on the left, so one would suppose the ink can get through but for some reason won't.
Sounds like the print head itself has clogged or some inks have become harder... can happen over time especially as you dont know how long inks have been on shelf before you bought them... some brands are better than others for that...

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.
