    Agree 100%, thanks @stratman for elaborating the cleaning process.

    In case of the PGI-9's, who have no sponge but a bag filled with ink, I would risk to reuse them in case no others are available as long as the outlet membrane is evenly coloured with liquid ink and you hear a sound when shaking.
    Watch also through the little window if you see the bag partially collapsed (according to the indicated ink level).
    Pushing on the cartridge (with the outlet on top) should show some ink drops raising above the mesh.

    When the bag is against the window without ink visible then air has entered the cartridge because the outlet membrane has dried out. Dried ink could indeed cause new clogs.

    In doubt do not insist. Best is to use the carts from the first printer since they worked recently.

    I soaked the print head over night and cleaned it with papertowels until they appeared very clean. There was a LOT of ink smeared at the print head. So It prints a little better. So directly after the cleaning it put out some yellow but then it disappeared again, the printer does not say the cartridge is empty. But the MBK stopped entirely and the printer says the cartridge is empty so I will replace it later today together with C M Y and G if they still don't print although they looked fine when I took them out (maybe the yellow was a little dry). The prints are sorted from top to bottom in deacreasing age.

    So many thanks for this active and informed support.

    Good work !

    As you concluded on your own you need to change some carts, I hope you have good ones.
    From my own experience the yellow is the first to dry in (forget about this one now - and maybe also the GY,C and M - you can flush them later on and refill).

    Normally, after cleaning and reinstalling a printhead, there is a priming cycle using quite some ink.
    After this the nozzle check should be OK.
    As said, do maximum 1 or 2 extra cleanings.
    If no result return to soaking and/or recheck the cartridges.

    @Jannis, I hate to say this but you’re going about this all the wrong way, how can you expect to trouble shoot when you don’t even know if the gun is loaded.

    Your heading for a big let-down if you continue, yes, it’s great you’re getting somewhere, but in actual fact you’re not, you’re continually cleaning the print head to what end, and that’s the real problem here.

    If you don’t know the state of the cartridges then your wasting your time and most likely you’ll damage the print head, if you haven’t done that all ready.

    Wait till you have a complete set of new cartridges and only then print a nozzle check, that will tell everything, as to whether the head is good or bad, if it is then great and it not then you’ll have to purchase a new one, there are no shortcut when trouble shooting a poor nozzle print out.

    Sorry for been so harsh but you could be at this till Christmas with the methods you are employing, so please start with known good cartridges, and give the print head a chance to show you its working properly, there is no other way...

    @Jannis:

    I suppose you did use the cartridges who where in the printer you try to revive ?

    According to your nozzle checks 5 were good (and the corresponding nozzles).
    The MBK nozzles were OK also but the cart empty afterwards.
    From the remaining 4 (GY, Y, C, M) we don't know if it are the nozzles or the carts.

    As @The Hat suggests, with every cartridge change, cleaning cycle and in particular a printhead change the printer purges a lot of ink and you will arrive in a carrousel of empty cartridges.

    In case you don't have good (at least others than the ones who are in now) MBK,C,M,Y and GY carts do not proceed.

    You need enough ink (in particular for the 9500 Mk I). Count a full set of carts before you're ready (that's at least €100 from Canon or €20 refill).
    This is the main reason why people stop using these printers and dump them (and that's why they end with us refillers since they make great prints at a reasonable - not cheap - price).
    I understand that you want to know if the printer is OK without investing too much.

    See my PM.

    @Jannis - You might as well return the print head to soaking and flushing for the next day or two while you get new cartridges.

    Well I have inserted new cartridges now and it got better again the only color missing is Yellow. Cyan has a small line in it. I have used the normal cleaning. I think I wait like a day for the new cartridge to wet everything before I unplug the printhead again to clean it if it still doesn't perform. Can I put water ontop of the printhead where the cartridges go or only the nozzles of the printhead?

    Since you did get Yellow after soaking, then return to soaking and flushing the print head. Use only these new cartridges for testing and only print nozzle checks.

    No need to. Start soaking as I wrote in an earlier post.

    Yes. The soaking solution should cover the ink inlet ports on the print head, where the cartridges connect to the print head, as well as the nozzles underneath the print head. Flushing under the tap in your sink should include directing the water both on the ink inlet ports on top and the nozzles below.

    @Jannis - Please use a scanner to digitalize the nozzle check if you have one. Whatever your method, crop the image (or move your camera closer) to focus only on the nozzle check and not the surrounding white paper. Also, more light would be helpful.
