I had th epower flicker a fwe times and now the estudio when i turn it on will only briefly light up and then it goes black. Is there a fuse or something?
Turn off the copier and unplug it from the wall. After a minute plug it back in and start it up. This will reset the power supply, if it doesnt work after a few tries, your power supply may have been damaged.
izzit toshiba DP2800 or es280? for DP2800 it always have this problem...the power board is super sensitive...try to plug-into a supply which is NOT shared by too many device..
