Epson, and many other manufacturers of ink jet printers, has come under fire in recent years for designing printer models that both do not use all of the ink in the cartridge, and also are equipped with monitors and sensors which remind people indecently to replace their cartridge, even if there are dozens more pages of ink left in the cartridge. However, thanks to this how to video and others like it, you can make the ink you buy last as long as possible, getting your moneys worth despite the efforts of the mothership.
As detailed in this video, Epson printers have a sensor which tells how much ink is left in the pan and warns whoever is using the computer connected to the printer, that they need to replace the cartridge. These warnings are incessant, popping up every time you print any document or turn the computer or printer off and on again. The logic of this system is to remind the user of low ink supply before they begin to print any high-quality or lengthy project, so that they can change the cartridge and not waste paper.
However, for most households this system is completely faulty, as simply printing off homework or addresses is the bulk of what the printer is there for. And actually replacing the cartridge when warned wastes a huge amount of ink and, correspondingly, money every year. By using these steps you can reset the system to accept a lower amount of ink, extending the life of your cartridge before the annoying warning messages pop up.
So, always understand the issues that come with your printer, and get the drop on dealing with them using online how-to guides like this one.
