Reset Canon PIXMA MP150

This is actually a very easy fix. Two absorber pads are located on the right side of the printer, under the ink cartridges. With the printer on, lift the top to expose the cartridges. They will automatically move out of the way. You can move them to the left side by hand if the printer is not on. You will probably need a flashlight to see the pads. They each sit in a rubber retainer. The pads can be removed very easily and cleaned. Take the pads out of the retainers with tweezers. They clean up nicely with warm water but you can use something like Simple Green if they are stubborn. It is best to use a spray bottle (on stream) and blast it through the pad until it is white. Sometimes just putting it under a running faucet will do the trick. If there is ink in the rubber retainer after taking the pad out, it can be cleaned up with a paper towel. Put the pads back into the retainers and you have successfully cleaned the ink absorbers. Now you may have to reset the error message so you can get back to printing. This is how to do it.
