Adjusting the eject enables both thin and thick
sheets of paper to be aligned neatly.
A long-life, high-brightness xenon arc lamp is
used to illuminate the documents. Since the
lamp's intensity is not affected by temperature
variation*
2 , printing quality at low temperatures
is greatly enhanced* 3 .
*2: The lamp is filled with xenon gas, which means
that it does not require heat to vaporize mercury,
as a fluorescent lamp does, and therefore its
intensity does not vary with temperature.
*3: Increased viscosity of the ink at low temperatures
results in fainter printing than at normal
temperatures.
Operation is simplified by concealing
occasionally-used keys under a panel, leaving
just the basic function keys permanently
accessible.
