HP 2200DTN flashing alert light

I am out of ideas on this one, so any help would be appreciated.

We have a HP 2200DTN printer with a flashing alert light. Have tried checking for paper jams, powering printer off for several minutes and turning back on, even tried to cold boot the printer and restore factory default settings.

All attempts have failed, and no matter what I have tried, I just keep getting the flashing alert light once I am done.

If anyone else has seen this problem, I’d love to have your input. I’m thinking it is time to replace or repair the unit.

Thanks in advance.
