    mp540 and mp550 printhead

    Guys, I would like to know if printheads for mp540 and mp550 are the same? I cannot get my mp550 work coz of a b200 error so I am thinking of fixing a second hand mp540 printhead into it. Do you think that would be possible?

    Blogged heads or old carts? Can not figure out.

    PeterBJ, it is hard to say how many times I refilled it but I bought the machine about 2 years ago and considering I am not a heavy user, I guess it amight have been refilled 7-10 times. When I refill it, about 25 percent of the tank remains empty. If I try to fill more, ink starts coming out of...

    Blogged heads or old carts? Can not figure out.

    Stratman, I'll flush the cart as you suggested but just one question. Once I take off the cart, do I need to put another one into the empty place to prevent the printheads from drying? Coz I guess it will take no less than one day to dry the sponge properly.

    Blogged heads or old carts? Can not figure out.

    Hi guys, I have a Canon MP550 and recently it's developed a problem of smudging the photos. What exactly happens is that when the print out comes out of the printer, I see very tiny horizontal green lines right at the end of photos (see the image). I don't know why they appear at the end. I did...

    PGI 520 accepts ink only less than half.

    Many people in this forum talk about flushing cartridges under the running water. I presume that the chip will not be damaged by the electricity in the water, right? Qwertydude, You may be right, coz I managed to refill the second hand one almost completely without any problem, probably because...

    PGI 520 accepts ink only less than half.

    What about the 'refilling hole'? seal it off or leave it open?

    PGI 520 accepts ink only less than half.

    Well, I saw the needle going all the way into the chamber, so I am not too sure if that was the cause. You say "no ink can get past all the dried ink in the sponge". I thought that was a clog issue, I was wrong apparently :rolleyes:. Anyway I ll do what u suggest. Just one more question. Can...

    PGI 520 accepts ink only less than half.

    Printer: Canon MP550 Problem: PGI 520 black cartridge Hi guys I had a couple of problems when refilling the original black cartridge. As instructed in the German Durchstich method , I opened a small hole but using a tiny drill bit. I started injecting the ink into the ink container but when...

    I see. Now I am much more clear about the issue, thank you for the advice...

    How do computers calculate the amount of the ink?

    When you say , do you mean that the printer may calculate the remaining ink level wrong even if, say, half of the cartridge is full when I use a refillable one?

    How do computers calculate the amount of the ink?

    Can someone please tell me how the remaining ink in a cartridge is calculated by a printer? Is there any way that a printer knows that it has a cartridge with a bigger or smaller ink tank than the one used previously and therefore calculate the ink levels correctly? The reason why I am asking...

    Canon mp550 - not recognised error!

    Yes, everything is OK and they are free from all sort of dirt. In fact, if this was the case, the printer wouldn't recognise the original ones as well (I think). Many thanks for the hand. :)

    Canon mp550 - not recognised error!

    Actually I have already replaced them but the problem still continues. The thing I cannot understand is if it is the chips that are mulfunctioning, they either work or not. In my case, they are sometimes recognised and at other times not. Anyway, I think I'll go for the OEMs and buy a chip...

    Canon mp550 - not recognised error!

    I'have gone through the posts but my problem is slighlty different than many of those "not recognised" errors. I am using refillable auto reset cartridges and place them into their slots, red light comes on. So, chips make a good contact, no problem with that. After they are installed, I can...

    German "Durchstich" refill method for the PGI-520/CLI-521 cartridges

    Thank both of you, and yes, I am in the same position as most were once :). One last thing, have you ever tried to make a hole close to top edge rather than making it at the bottom? Do you think that would make any problem if I did so?

    German "Durchstich" refill method for the PGI-520/CLI-521 cartridges

    Thanks a lot for the advice guys. ghwellsjr, You put a piece tape over it but doesn't it come off when it gets wet? The Hat, Does it make any difference if I keep the cartridge in either position when refilling it? Also do you know that how much ink the new cartridges take i.e. 5ml, 10ml...
