If the printer is going through the motions but is producing blank paper, what could b the problem? The ink cartridge has been replaced properly so thats not it, any other ideas?
Assuming that the printer worked in the first place... Print heads could be fouled - try running the cleaning cycle four or five times. If you have an Epson then the print heads are separate from the cartridge and could have fouled up through dry ink or media. Replacement heads can be had but the cost is such that you are better off forking out for a new printer - assuming you have a simple home inkjet printer value circa �75.
It is possible that no ink is coming out of the cartridge due to an air block, if it is the type of cartridge that is pierced at the top, blow in the hole until ink comes out at the bottom.
