You can check this by doing an EEPROM information print in service mode (see below). Look for the part which says PAGE=xxx or PAGE(All=xxx). I don't know about the i960, but the i950 has a life expectancy of 10000 pages for the body and 9000 pages for the print head, according to the service...

Thank you for testing this, I think this thread is really interesting! Let me add a third theory to the two ones mentioned above: As I quoted before, the printhead is probably designed to help bi-directional printing. But the nozzle check is done in one pass (uni-directional). This probably...

A little update to the refill method mentioned above: I refilled my own carts now 4-5 times with it. No problems so far. Another owner and heavy user of an iP5200 reported that he refilled his own carts 30-50 times each with this method (Inktec ink), and that they are still going strong. This...

Oh yes, I overlooked that. :) Great, thanks for testing this! I wonder why there are nearly no tiny dots scattered around on the "taped" print. On the first pic you can see mainly two large dots and a small one... on the second pic you can mostly see one large dot.

Very interesting. I wonder why the letters are completely yellow. I guess this is because they consist of yellow and the cyan and magenta nozzles which you taped. The other cyan and magenta nozzles seem not to be used for the letters.

Perhaps this could also happen the other way round (a faulty head destroys every printer)?

That's a pity for the sake of science, but perhaps a good thing for your print head :D I think if you had one, we would see one of the following two possibilities: (a) The nozzle check of magenta and cyan would look normal, but somewhat brighter, because every dot of magenta and cyan consists...

Wow, very nice! The canon article is also very informative. May I ask how exactly the nozzle check print was looking when you did the cellophane test? Did you also try an extended nozzle check? I guess the normal nozzle check looked quite normal, with cyan and magenta somewhat brighter*, and...

I'm looking forward to your new findings! :) It seems that the position of the dye black is not important then, because it seems to differ from my iP5200: Btw here are the nozzle setups for two other Canon printers, according to this (german) site: iP4300 (=iP5200): 512 PGBK 512 photoBK...

Thank you for your reply! In the service manual for the S600 I read this: and then it shows a schematic which looks like this: Bk(even), Bk(odd) | C1(even, M1(even), Y1(even), Y2(odd), M2(odd), C2(odd) But frankly, I don't know how this is meant exactly, and if it would have any implications...

This microscope stuff is very interesting! The cartoon is not that funny... it says: "Are you happy with your new inkjet printer, colleague?"

This is really very interesting, thank you for posting! I'm wondering about the following: 1. Are there different nozzles for the small drops and the large drops, or can the same nozzle produce different sizes? -> I guess the answer is A (different nozzles). This leads to next question: 2...

The edgeshooter (Canon) ejects ink to the side of the heating element. The roofshooter a.k.a. sideshooter (HP, Lexmark) ejects ink directly forward. The roofshooter design is said to be used mainly in carts with a throwaway printhead, because of the following problem: after a drop of ink is...

An interesting article with pictures how nozzles look which were destroyed by ultrasonic cleaning: A scientific approach to remanufacturing ink jet cartridges: the HP629A But maybe Canon printheads as edgeshooters are not so easily destroyed by the microscopic bubbles as roofshooters like...

A german site reviewed the solution from Armor (France, blue adaptor)/Geha (Germany, red adaptor): http://www.druckerchannel.de/artikel.php?ID=1784 To sum it up: - The carts function nearly exactly like the Canon carts. You retain the ink level indication, but you can only use Geha/Armor carts...

I made a similar test some days ago: I printed a nozzle check on plain paper and put it in a bowl of water for 10 minutes. I used Inktec nozzle checks (some days old) and Canon OEM (4 months old) with my iP5200. Here is the result: As you can see, neither Canon nor Inktec pigment black is...

First you should make sure that the chips are positioned correctly on the cart and that nothing blocks the light path of the LED - it is needed to let the printer know where a cart is positioned in the head. If everything is okay, you probably have a broken chip and need to replace it with a...

I guess you mean these two pictures: http://webpages.charter.net/haeffkr/pics/nozzle_check_before.jpg http://webpages.charter.net/haeffkr/pics/nozzle_check_aftercleaning.jpg They are really strange, because they should look like this: normal i560 nozzle check Reasons for a bad nozzle check can...

The pic you posted looks like every other row is missing yellow and cyan, so only magenta and black are there. The situation now I don't know, so I would advise to do a nozzle test and show it here.

Seems to be this one: continuous alternate blinking - ROM error - replace the logic board assembly it's the same error code for the iP4200.
