Got as far as "remove the two springs", which my HP 3520 does not appear to have. Must be a different version.

I'm not familiar with that model, but, don't most HP inkjet printers have the print head incorporated into the ink cartridges?

All of the HP models we have are like that, anyway....

Indeed, on the 3520 the printhead is integrated in to each of the cartridges, so when you replace a cartridge you are also replacing that particular printhead.
A common feature of many HP inkjet printers.

I am familiar with HP printers that have inkjets in the cartridge, but mine does not. It has four relatively small cartridges, three color and one black. I was looking for a way to remove the printhead, because it is very difficult to clean, and I am hoping that the issue is that it is dried out. I thought that it might be a firmware issue, but everything seems normal, except for absolutely no ink on the page. Also, the lack of ink happened somewhat gradually, which to me supports the dried-out possibility. I still think that the original poster was referring to a different model. There seems to be no way to remove the printhead without taking things apart, that being next to impossible as well. One HP response mentioned replacing the yellow cartridge to solve an issue with black printing, but it is puzzling how that could have any effect.

Right now I have left a small amount of rubbing alcohol sitting in the black receptacle to the printhead, hoping that given some time it will work its way through. I have not seen any evidence of alcohol passing through to the printhead, which the cleaning help indicates should happen. Perhaps not the best thing to do, but I have run out of options, and have little to lose anyway.

For some time I have felt that HP provides very good hardware, mediocre software, but poor support. Recently I had an issue connecting to the embedded web server in the printer. Unbelievably, the solution from HP was, surprise surprise, buy a new printer. It is not likely that I will do that, because I have very little need for printing, which means that I am likely to encounter similar problems. Probably won't be an HP if I do.

Thanks for your replies.

If I may offer an opinion for your consideration....

HP makes some awesome printers and, personally-speaking, I prefer their Laser printers to anyone else's.

Their strategy of incorporating the printhead into their ink cartridges, on their inkjet printers, is a wise move, IMHO. We have had very few problems with the HP inkjets that we have; while the Epson inkjets that we have had (which have the ink supply separate from a printer-mounted printhead) have been a nightmare by comparison.

Instead of completely abandoning HP, wouldn't it be better to just select an HP model that implements the ink cartridge integrated printhead for your next printer purchase?
