Digital BW, The Print

My trusty 1280 with CIS quit printing this morning. It had completed one
print. However, before loading the sheet for the second print in the queue,
the Maintenance Light and Power Light began flashing alternately. I got a
message telling me to clear the paper path and turn the printer off, but the
paper path is clear. I've tried turning the printer off and back on several
times and tried to print a test print without success.

The manual doesn't describe this flashing lights combination. Is the printer
telling me the waste ink pad is full or what?
