Question about HP Officejet Pro L7580 All-In-One InkJet Printer
I just installed an L7580 printer I brought home from work, where it worked fine. Now it powers up, but does not respond. An "!" lights up, but there is no associated error message.
btw... I did accidentally plug it into the wrong power cord first (for a 2510). But the HP support site suggests trying a power cord out on a different device if your machine won't reboot; that suggests to me that this is okay.
Not neccesarily.. the voltages are different for each printers power supply. is it a power cable with a little black box on it? or just a straight power cable to the wall?
The 2510 may have a diferent voltage.. you can tell by looking on the bottom of the black box and see what the OUTPUT is.. is they're different.. time to go shopping
