Hi folks. Not sure if I'm in the right place, but looking for some advice. I have a Photosmart 7550 printer, nothing too extravagant but a good printer. Recently the pulley cable that pulls the cartridge cart (the rubber cable with ridges) broke on me. I'm looking for a replacement, as I can't imagine the cable could be that expensive and would save me from having to purchase a new printer. No luck from HP directly, and any other "parts" printers I've found (Ebay, for example) aren't wide enough to possibly have the same size cable as my current. Any advice? Thanks in advance!
