Thank you for confirming,
this would unfortunately confirm a deeper hardware failure here, meaning a defect in the carriage or paper feed path.
As this is a 2006 model printer, that type of failure is not at all surprising to see just from normal age related wear and tear, as they are really built for only a 3 year service life.
The printer would need to be replaced at this point as it would not be feasible to repair. Unfortunately no current model, or really anything in about the last 9 years has used those same cartridges, so they won't be usable with a future model.
If looking for a replacement, I’d recommend any of the Epson workforce series printers. They tend to be very reliable, are easy to set up and use, have good print quality, and reasonably priced ink. Example: http://amzn.to/1nxc4II or http://amzn.to/1nxc8Z5
Note that these, like all consumer grade inkjet printers, are designed to be low cost and are essentially disposable after a few years, subsidized by the high cost of ink cartridges. If you wish to have a better quality and longer lasting printer, that comes with years worth of ink up front, consider the Epson ecotank models instead: http://amzn.to/1nxcejv
Alternately, for a more business/commercial grade product that will be rated for a 5 year life, consider a laser printer. Lasers cost more up front also, but a toner cartridge can last for thousands of pages. A black only all in one laser is around $125: http://amzn.to/1nxcpv2
while a color model is about twice that: http://amzn.to/1nxcnn0
My apologies for the news,
