Probably the logic got corrupted.
You can appreciate a computer or even a digi TV set-top box wants a
re-boot by disconnecting the power once in a while this is usually
known as a 'soft reboot'.
Sometimes with a computer you take the bios battery out, a digi TV
set-top box you hold a button while plugging the power cord in, these
are known as 'hard re-boots' where the chips do a self check.
More than likely you have performed a 'Hard re-boot', these 'lock ups'
can cause all sorts of funny problems, one cause could probably be a
dirty great big spike or voltage surge on the mains power, these
voltage surges are so rapid you need special equipment to see them a
simple 'test meter' being far too slow to respond to register them
but fast enough to corrupt.
Strange you had to remove the print head....?
