Hello, Tanya -
I tried using the Canon Find A Service Location web page,
but, it seems the search logic does not accept MP495 as a valid Canon printer model number. Do you mean the PIXMA MP495? If so . . . this is what came up when I entered PIXMA MP495 and a Louisville, Kentucky zip code:

While trying to find more information on the Canon MP495 printer, I came across information about the 5800 error code and the ink absorber being full, here:

HI an error 5800 came up on my canon printer mp495 that my ink absorber is full. How do i clean it? . . . [snip] I have the printer about 2yrs and i haven't updated software
Unfortunately, there is no quick or easy fix here. This message indicates a hardware problem, specifically that that the internal "ink absorber system" is full. The ink absorber is a series of pads/tanks, which catch drips from the printhead when parked, and is also used for maintenance tasks like cleaning and purging.
Eventually this absorber fills up, and the printer shuts down operations, as continuing to operate it can result in ink overflowing the system, damaging your desk, flooring, etc
While it is sometimes possible to temporarily reset the counter, this is dangerous as the system will likely overflow. Cleaning/emptying/replacing the system is a difficult and messy process as well, best left to a qualified service technician. This service is generally not practical though - it's going to run you $150-250 for repairs, which just isn't worth it for an older printer. This is a 7 year old model, that was built for a service life of no more than 3 years. If you have reached the point that the absorber has filled, 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.
From other information I found, it appears the Canon PIXMA MP495 came out in mid-2010. Do you recall when you purchased your printer? As the long explanation I posted above states, the estimated service life of the PIXMA MP495 was no more than 3 years.
So, your only option seems to be to purchase a new printer.
