On occasion when I start up my 3 1/2 year-old Epson 4900 printer I get Error 1138, which says to call Epson if it doesn't go away after restarting. It has appeared about 3 times in the last few months (unfortunately after the 3-year extended warranty) and the printer has rebooted successfully after powering down and restarting.
I googled the error and it says "Over Current Error." Does anybody with Epsons have experience with this? A call to Epson would be expensive now that the printer is beyond warranty.
