[GreenKeys] Fwd: Teletypewriter with Harris

[Nick England]

Before applying power, you should turn the motor by hand to be sure the
printing mechanism is not frozen due to damage or gunked up grease.

Just “humming” probably indicates something is frozen and the motor is
stalled. I hope he didn’t leave it on long enough to overheat/damage the
motor.

If it wasn’t frozen, you’d expect it to be whirring with gear noises and
trying to print blank characters. This is known as “running open” because
the signal line is open and that is equivalent to printing blanks. I have
never heard a model 26 so someone else should pipe in if it sounds much
different from a 15 or 28. But still this should only be a brief test - how
far would you drive a car with no oil?
