Question about Canon MultiPASS MP730 All-In-One InkJet Printer
Prints in blue and green ; all ink cartridges are full
If your ink cartridges are all full then the print head which houses the ink cartridges is probably plugged, meaning the nozzels in the print head that spray the ink onto the paper are plugged by dried ink or debris. By flipping the gray lever up on the printer carriage you can reach into the carriage and pull the print head out...after removing the ink cartridges of course. This removal can be a bit awkward but it will come out with a little wiggling. When removed you can flip the print head over and view the ink nozzles. these nozzles will need to be soaked in warm water. Stand the print head in a saucer or shallow bowl and pour a small amount of warm water in the saucer or bowl. Let it sit in about an eight inch of water for 20 minutes and then set it out on a pile of paper towels. You'll see a lot of color soak into the towels. Repeat this process until no more pigment drains out. Don't get water up on the contact pad on the rear of the print head. Dry assembly with towels and you could blow dry it also with a hair drier...but not too hot. Reinstall and run 2 cleaning cycles. The degree of the plugging and the age of the print head will determine the effectiveness of this maintenance. If you are not successful the first time try the cleaning again. Otherwise you can order a new printhead for around $50. I have done both for my MP730 successfully. Hope this helps!!

Dear Dahcota; If it has a single color cartridge, there are three components inside the cartridge-red, green, blue, and all colors are a superimposition of these 3 basic colours RGB in different proportions. It looks like the red component has run dry. So, what you get is the color without the red component. If its showing all cartridges as being full, sometimes these levels shown are inaccurate. Try changing the entire color cartrigde or red component, then see if you still have the same problem. What I am not sure is if the red cartridge is a separate entity . If the red is separate, and changing it does not improve things, the connection in the printer might be faulty. Go to www.hp.com and browse for the correct make ask them online there, It should really be okay, once you have replaced the red or entire color cartridge is it is a single unit with all 3 colours

Hi cmwierson, I would suggest you update your printer drivers, try this, follow instructions exactly as written:
Create a new folder on your desktop and name it newhpdrivers(substitute your manufacturer in new name). Un-intall printer and printer software completely. Go to manufacturers website and navigate to their drivers/downloads or support menu. Select your model, choose the relevant software and download to the new folder you created on your desktop(watch for the light yellow bar at the top of window viewing pane, click on this and choose – download file - . Power down your computer. Reconnect the printer to the computer and turn printer on. Power on pc. Windows will detect new hardware and ask if you have the manufacturers install cd or a location to check for install files. Direct the wizard to your new software, follow the rest of the setup instructions and your done.

SOURCE: Black ink won't print.
Disconnect the printer or at least be sure it is turned off.
I'd do both and reinstall the CD software program that came with
the printer. When the software program asks you to connect the
printer to the USB port, do so and it should again work properly.
Hope this helps. Bud
