[GreenKeys] Leigh Branded KSR33 Restoration

[Larry Tighe]

I've had the same problem with the CR on my 32 and 33's.  My solution 
(heresy, I know).....give the CR clutch a massive dose of WD-40, thence, 
press the CR while holding the RPT (repeat) key down.

It's a good idea to hold down the space bar to advance the carriage to about 
midway or more so you know when the clutch actually starts working.

Give it some 5 second bursts of CR RPT.  Eventually the clutch should yield 
and slowly, it will work and become dependable.  It needs exercise and the 
RPT key is the way to go.

>> Bell: Does Not Work
>> Form Control (HTab, VTab, FFeed): Forgot to test.

>> TX/RX (Remote): Can't Test
>> WRU?: Works when triggered (drum is fully intact no characters entered), 
>> forgot to test Auto Answerback.
