C5280

[Dave6567]

While I was watching a you tube video, my system shut down for a second, the UPS beeped a couple times, then the system rebooted itself. When it started back up, the C5280 printer showed a solid exclamation mark, the LCD screen is blank, and the scanner light is on. None of the push buttons on the printer work. The power supply reads 16 and 32 volts.

 I really like this printer. Is it dead? What can I check?

Thank you for posting on HP Support Community.

Don't worry as I'll be glad to help, I have a few troubleshooting steps we could try to fix the issue:  

• With the printer turned on, disconnect the power cord from the rear of the printer and also unplug the power cord from the wall outlet.
• Remove USB cable, if present.
• Wait for 2-3 minutes, press and hold the power button on your printer for about 30 seconds to remove any additional charge.
• Now plug back the power cable straight to a wall outlet without any surge protector or an extension cord (This is important) and then plug back the power cord to the printer.
• Turn on the printer and wait till warm-up period finishes and the printer is idle.

Hope this helps! Keep me posted for further assistance.

Thanks for the suggestion.

I tried the reset, but it didn't work. I still have a solid exclamation mark when I plug in the printer, and the pushbuttons and display are all dead. The scanner bulb remains lit.

I also checked the power supply and it tests 16 and 32 volts dc as it should.

The printer was plugged in to a UPS with surge protection when it went bad, but could it have still been affected by some kind of power spike?
