So, I went to the store today to buy a new printer cartridge. Well, nothing at walmart seemed to fit my HP printer, so I bought another brand's printer refills, since I'd been planning on buying refilled cartridges from another store (that was closed) anyway. I figured it out, and I refilled the black one with no problem (that I know of...it's in a tin can right now overnight to get the leaking out of its system). The color one, however... Ok, so I have no idea why, but we run out of yellow and have lots of red and blue leftover. We've done it to two printer cartridges. So, I refilled the blue (it took the whole little squeeze bottle without any problems), and then I refilled the red (and it overflowed), and then I refilled the yellow (it took the whole little squeeze bottle, of course, without any problems). And then I try and use it, and...the blue has stopped working. The same site that gave me the instructions told me how to "unclog" it by soaking the tip in warm water...yah, big help. Now the yellow stopped working as well, and the red is being kinda iffy. [sighs] Tomorrow, I'm going by the printer store and giving them the other one, buying a newly refilled one, and asking what I can do with the other refilled-but-not-working one. Stupid print cartridge.
