Need to turn off fuser HP Laserjet 4L.

Mike,

I really dont think that could work because if you turn off the
thermistor or whatever a fault will alert the printer logic board that
the fuser is going to either over heat causing a fire, or will not
heat at all and will give you a 50 error which is a fuser related
error, good thinking though!

No , this cannot happen, because when the paper is being fed into the
fuser the other half of the page i still going through the toner
cartridge.

Didn't get any useful info, so I just did it.
Ripped out the fuser. Put a 4.7K resistor in place of the thermistor.
Get about 80% of a page before it stops. Working great.
