Recently I was working at a client’s office moving some equipment around. When I went to test the printer, I noticed that the power and ready lights were blinking off and on in unison. I figured there was most likely a problem with the ink cartridges, so I removed them. Upon reinstalling the ink cartridges, I had some difficulty getting the yellow ink to fit. Then I noticed something: half of the four ink cartridges were the wrong ones for this printer. After confirming with staff that the printer had previously been working, I proceeded to force the cartridge into the carriage. Viola! We got a successful Windows test page, thought the utility can’t seem to identify the wrong cartridges:
It had never occurred to me to try this before. I wouldn’t recommend this, but if you have an Epson Stylus printer, you may be able to pull it off.
