MY printer prints blank pages

probably an ink cartridge problem..Try executing nozzle check on the maintenance tab on printer and faxes then check the results if it prints properly. if there is still a problem deep cleaning is recommended and if it doesn't work then its the time to replace both black and color ink cartridges.

Printer goes through motion of printing but no ink printed. Cartridges are full and properly installed. Print test = no ink

fir make sure you have loaded the ink cartridges correctly by removing the tape on the top and make sure it snaps in place. Once you have ensured that there is ink and properly seated. perform a nozzle test and check the colors, you should follow the instructions on the screen. if it still doesn't print correctly or at all I would then do a cleaning of the print heads. and then do another nozzle test if still not correct, then do a deep cleaning and another nozzle test. if after all of those things are completed and you still cannot print, then call manufacturer of printer and see about your services and or options.

Canon pixma ip4000 color not printing correctly with full inks

In both cases be sure using correct ink. Use of generic ink can lead to leakage of catrridge seats do to crossion from inferrior ink quality (per Cannon). Be sure ink in proper locations - see manual. Run the maintenance proceedures: cleaning then print nozzle pattern. If all colors are not proper after two or three cleanings, perform deep cleaning. Print nozzle pattern after each cleaning. This should clear up problem. If not, print head may need replacement.
