Possibly I could buy a second hand iP4000 to use these ink tanks in (they also fit the iP3000 and a couple of others). BUT, I've got a couple of sets of unused ink tanks for this printer which are worth, in toto, more than the printer itself and I'd hate to waste them. What I need to do is put another print head in my printer and see if it fixes my problem (if it doesn't, it's probably an electronic fault elsewhere in the printer and would cost more to fix than the printer is worth. Also it may not be economically viable to buy a new print head given the age of this printer BUT the Canon iP4000 is, and is recognised as, a good printer.

Somewhere else on the net I read that the printer flash codes are notoriously inaccurate so if I bought a new print head I may be stuck with it AND a faulty printer. I was thinking of buying a new print head but I read somewhere on the net someone with the same problem replaced his print head and it didn't fix his problem. I've even cleaned out the waste ink tank and sqeezed-out the felt pads (what a messy job that is ! ! ).

I've also reinstalled the printer driver (for Vista 32 bit), I've soaked the print head in water for a few days and under flowing hot water several times. If the print head is taken out and the lid is closed, there is a steady green light.) I've since done all the things recommended in the manual (cleaned the print head electric contacts, switched on and switched off, disconnected and reconnected the USB cable, etc).

(If the lid over the ink tanks is opened, even minutely, the flash code changes to continuous green flashes. There was no onset of blurry printing it went from perfect prints to nothing.

Never attempt to plug the power cord into the power outlet or unplug the power cord when your. A couple of minutes after a print job, I tried to print again but the printer had stopped working and the flash code was (and still is) five amber flashes then one green flash indicating a problem with the print head.
