flashing light bar

[villagedevelopm]

M209 has flashing orange light bar on the front of the machine and it refuses to print.

Disconnecting then reconnecting the power cord temporarily "fixes" the problem and the printer works normally, briefly. Then without calling for printing, just sitting idly, the light bar starts again and the printer won't work.

Disconnecting the com cable had not impact to the problem.

Tried a new toner, no change.

Tried the old toner again, no change.

Printer has worked flawlessly for two years until this.

Help appreciated!
