Believe it or not… your printer might be lying to you!
A recent study by PC Magazine found that most printers indicated the cartridges were empty even when they were not.
In fact some printers showed a low ink level warning even when the cartridges had as much as 40% of its ink left in the cartridge.
If your printer is giving you a low ink or empty ink warning you can try taking the cartridge out of the printer and simply shake it a little, then putting it back in the printer.
This can help the cartridge release some of the ink and extending the life of the cartridge.
