When I turn on my Epson stylus CX6400, it has the message "error-Printer error-See your documentation and call service if necessary." The only thing the documentation manual says about this error is to locate your locate service rep.

you can find the manual here

I had the same problem and this worked.

1. Turn OFF the printer.
2. Press B/W + Color + Stop button together and hold
3. Press Power ON button and hold (4 buttons on hold now and don’t release the buttons until you see the light indicator is blinking. A message will be displayed on the LCD)
4. Release all buttons.
5. Press the Color button once
6. Turn OFF the printer.
7. Turn ON the printer and the protection counter should be resetted

Printer menu drop down.
Change cartridge prog.

Sounds like the ink counters need resetting (it happens with other printers as well)

Go here for more info as the prog supports your printer

pull the plug and unplug it again..or load and unload your cartridge..,or change the cartridge you using...maybe the printer don't recognize the printhead..

I assume you've checked and done all the basic things like a power down and power up reset and checked to make sure all the ink cartdridges are properly installed and seated.

The user manual discusses your error message and suggests you do the following: Open the scanner unit to make sure any tape securing the ink cartridge holder has been removed; close the scanner unit/ press the ON button to turn off the CX6400, then turn it back on . If the error message still appears, contact your epson dealer or Epson tech support. If so,then you may want to get direct support and information from Epson at this website : http://er.epson.com:8001/start?TM=false&CMD=iSearch&CB=1886098358&LG=1&TP=NoviceCase&Q1-1-1886170412=1886170410&FI=1&firstQuestionID=Q1-1-1886170412&firstAnswerID=1886170410&category=allinone&model=cx64__&displaymodel=Epson+Stylus+CX6400&referralmodel=Stylus-CX6400&restart=yes
