Solution Ink Out Error for Epson Printer

One of the problem on the Epson printer when ink level indicator is empty will show Ink Out error message when printing. This problem is usually marked with the ink led/ resume led  is light (not blinking) and when view ink level indicator the printer status on computer it show the cartridge indicator is empty and marked with X. To solve this problem, on the canon printer you can press button combination to reset the ink level but on the Epson printer you need chips resetter or on old version Epson printer you can use software resetter like SSC server or adjustment program.
In the Epson printer this problem usually appear if you use original Epson cartridges (on new Epson printer model, C79 above) and this problem cannot be reset using resetter but on old version Epson printer such as Epson C45, C67, C58, etc you can reset the cartridge using cartridge resetter.

To solve “Ink out error” problem for Epson Printer you can use one of the following methods:

1. Change the Epson Cartirdge with compatible Epson cartridge or replace the Epson chips  with auto-reset chips.
2. Reset Chips of cartridges using chips resetter (Chips resetter available for old Epson version only). You can buy chip resetter on computer or printer shops near you home. If you use old epson printer model you can reset the chips using SSC software but this software not support for new Epson printer models.
3. Replace old cartridge with new cartridges, this is last solution if the both methods above not solve the problem. Before replace with new cartridge, check beforehand whether the problem is really caused by a cartridge or not because I found some ink out error is not caused by chips but cause by cartridge not installed correctly.

I hope this post can help you to solve “Ink out error” problem in your Epson printer
