Nope, still having the tire mark looking nozzle check patterns. I'm about to give up on these things.

Just got back from a week-long road trip, some of the heads have been in the printers, while others are still soaked. Will report the conditions of the heads as soon as I test them out.

Still the tire marks are still showing up...

It's pretty easy, I mean most of the Canons are very easy to take apart, normally involves a couple of screws and a bunch of plastic snappers, look all over the printer and you should see them. I wish I can help you more but I don't have ip4500.

Probably not if your purge tubes are clogged. Just take the thing apart and wash the ink absorption pad as well as the purge unit, including the tubes. I once had ip4200 with stuck purging unit, did everything and didn't help. And I'm guessing the clog was caused by the pigment ink, after a...

Just done putting the printer back together, and yes the purge system is in excellent condition. Fluid doesn't stay on the purging pads, pipes are clean and clear, bottom absorption pads are clean and dry. Replaced inks and did deep head cleaning for 5 times, and ink level are down. Sadly, tire...

That's what I thought, only one of the heads (the original one from i9900) was suffering from the symptom even after I let it sit for almost 2 weeks. Now I'm guessing if there's some foreign contamination inside of the ink pipe? I almost want to just print a good 30 pages of something and see...

The two black lines on the original nozzle check are my fault, I put the print head on that sheet at some point.

Alright, let me try this again. The original nozzle check: Nozzle check after disassemble and reassemble:

My damn scanner won't pick up the light colors, will try again tomorrow at work. Also, I'm trying to get some more i9900 print heads off eBay for testing. I probably will end up getting one from Canon, but I'd rather try all other options before that.

mebguy, thanks for the input, but I'm sure the purge system works fine. When I first got this printer I took the whole printer apart, flushed the pads in the bottom, dissembled and washed the purge system (man I like dye based ink, they came off very easily), and put back together and tested...

Thanks mikling for the info and such a quick response! I've been taking things apart for long time now. I took apart my Nikon D80 the 2nd day I got it, and it's still working today. All my canon printers are being taken apart and put back together, without instructions (MP830 was a bit tough)...

Hi, at this moment I'm just short of microwaving my printers. I rescued a i9900 about 2 months ago and till now it's still having trouble with print heads, all 4 of them. From the person getting rid of it, he said his ink was no good and killed the print head, so I dismembered the print head...
