Error message I replaced the ink cartridges now I get an error message. The error message is  Printer error - - - -  See your documentation and call service if necessary. I dont even know where to call.

The printer found error on it

This resolution, the only working one I could find for the generic "Printer Error" message, was posted by FixYa user willyinfcva:

"I downloaded the Epson CX5400 manual from 2manuals.com, and the remedies for the printer error light were plain and fell into 5 categories; print or carriage motor ohms out of spec (not likely), a latch holding the paper eject mechanism not locked down, or one of the sensors for head or paper position not functioning properly. Confident with this new information, I aerodusted both sensors, cleaned a smudge off the CR alignment strip behind the head carriage, and also reseated the head for good luck, as I'd had it out before. I ran a test and ... it worked!"

Hi, I am assuming that you tried to turn it off and on again, also are there any lights flashing on the machine? If you go to the Epson website and choose support you can choose your printer and go through a troubleshooter which has some simple problems, but if you don't feel comfortable doing that then contacting a service center would probably be easier for you. Depending on where you are in the world there are several ways to contact your service center. I am posting the site for USA but if that is not where you are then let me know and I will give you the link for your closest place otherwise you may be able to navigate your way from the link that I am sending you.
Let us know how you go.
