First, I'm not sure if this is the best place for this question, so Dwight, if there is a better forum, please feel free to move it.
Anyway, my printer, for some weird and unknown reason, is not working. I tried to print something and it made this sort of buzzing noise, then this thing came up to say that the cartrige couldn't move and to check for a paper jam. I checked, there was no jam. I can slide the cartrige along it's little bar, but it doesn't seem to be catching on whatever electrionically makes it move. It worked fine last night, so I don't quite understand what he heck is going on. Oh, and my printer is an hp deskjet 3420 if that makes any difference.

Kal, I've seen this sort of review for your HP printer several times upon searching:

Pros: Compact size. Decent print quality.
Cons: Mechanism breaks. Ink cartridges small

It was nice and compact and did a pretty good job as long as it lasted.... The print cartridge mechanism broke away from the belt that moves it- too expensive to fix and out of the short 90-day warranty period. The ink cartridges are very small- it went through them like candy- and a replacement set cost more than the printer!

Crappy! It would figure that my stupid printer was a free offer dealy when you buy a computer. Well, if warranty is only 90 (how ridiculous) I guess i'm better off just to buy a new printer than the pay more than the printer itself costed to get it fixed. It was a loud printer anyway

I've had several clients with this printer that had the same problem. I could not fix them for less than the cost of purchasing a new printer, so that is what each client did.
