Question about Canon Office Equipment & Supplies
Buy a new print head vs. buying a new printer. The iP4000 is a great printer with proven history. the latest printers on the shelf are disposable and you will be buying a new one every 2-3 years. The print heads are available through other vendors besides Canon direct. Try this website to see if they have your print head and their prices. PrinterFixer.net

I'm not sure what you did. We have 3 MP780 and IP6000 and 9000 printers. The frequent problem have is streaking usually w/ refilled cartridges and even new cartridges. This is what we usually do:
1. Take the printhead out and dip it in 1-2mm depth hot water. Hopefully the water changes color and clears up the clog. Keep the Circuits dry. Wipe off excess water when you are done.
2. For really difficult clogs, if the hot water doesn't work I find a small rubber hose and syringe that encloses(meaning air tight) the mesh in the printhead where the ink goes in. I then pump air in to clear out the clog.
3. Since you have to do it for the Black 3e, you might as well do it also for all the others to make sure they are not clogged.
Make sure when you pump in the air the syringe is not touching the mesh in the printhead. If these don't work then you can try borrow the printhead of another printer and testing it out. If it works then you need to buy the printhead. If Canon has stock, you should get it fast. If not, and you really need to print either go to a printing service or buy a new printer. Good luck.
