Error light on, printer error, how do I reset, I

Error light as soon as turn on? Status monitor at computer? SSC ver 4.3 support this type. Find at indoreset.blogspot.com

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!"
