Okay if it will not move at all, then the purge/absorber system is damage and that is what is causing this.
It is something that would need to be repaired, but it is absolutely not worth fixing, or even having it looked at - it's going to run you $150-250 for repairs, which just isn't worth it for an older printer. This is a 4 year old model, that was built for a maximum service life of 3 years. If you have reached the point that the absorber has failed, then other wear items like the printhead, feed rollers, etc are also going to be at the end of their lives and need service/replacement soon.
Given the costs and complexity of fixing this issue, you'd be better off replacing the printer. You can get a brand new and better machine, with current technology and a fresh warranty, for about $80, which makes more sense than investing in the older machine.
I can recommend replacement options for you if you'd like, or if you'd prefer to try having it serviced or working on it yourself, I can advise further on those options. Replacement would be your best bet though, economically speaking.
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/208LtQk or http://amzn.to/1NYUF1P
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/1PpOj0C
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/1JSHOlQ
while a color model is about twice that: http://amzn.to/1n4I7Q5
