Hi Sunshyn2005,
I checked the link you sent me and it lists the firmware version as ELM1CN1320AR but my printer has ELM1CN1409AR installed which appears to be a newer version (1320 < 1409)?
The check for updates function on the printer front page says it is up to date already.
I will also plug the printer into the wall instead of the UPS, but that article was for LaserJet printers and I know they draw a lot more current than InkJet so I doubt that is the problem.
Thanks,
Danno
