Modern Epson printers have built in software / firmware that counts the prints that you do and each model has a set limit that will generate messages, saying something like "your printer requires maintenance" or "parts inside your printer may be worn". These messages will continue unless you reset the 'Protection Counter', this period is called the 'Overflow'. Each model also has a set amount of prints allowed on the Overflow, after which your printer will stop working and lock you out completely (we call this 'Lock Out'), usually with two alternating flashing lights on the printer.
All is not lost!
You can unlock it, reset the overflow and reset the protection counter, bringing your printer back to life.

This means that, all you really need to have is your printer's resetting software.
