The print head on the NX400 printer is integrated into the ink cartridge and therefore when you remove the cartridge you are removing the print head. . . If you want to clean the print heads / nozzles then see the procedure in the NX400 User Guide in the section for Adjust Print Quality. . . .The User Guide can be found at http://www.epson.com/cgi-bin/Store/support/supDetail.jsp?BV_UseBVCookie=yes&infoType=Doc&oid=106004&prodoid=63075469

Did you try already using the replacement utility.?

The answer is Yes.

Best would be 10-LB.

Good Luck.

Try to run the ink pad reset utility software.
Please log on to epson.com. The software runs on win xp and win vista.

I had exactly the same problem. I changed location from Easysync on my HTC P3300 from memorycard to internal memory. It worked!!

Using easysync 4.26
Lotus Notes 8.0.2
Active Sync 4.5

To print card stock you must us the manual slot in the front of the printer and feed one at a time. Also open the back flap door so the card stock can exit out the back instead of trying to bend around for the try. That will give you the staight paper path that your thick stock needs.
