Print Speed
There are two PRINT SPEED indicator lights:
The sequence of lights shows which print speed is
active:
 Normal
 HIGH-SPEED
QUIET
HIGH-COPY
( = light off,  = light on,  = blinking light)
The default PRINT SPEED is “Normal.”
To change the PRINT SPEED press the PRINT SPEED
key. Each time the key is pressed the light sequence
above the PRINT SPEED key changes until all the
options have been cycled through.
Printer Reset
Clearing some error conditions requires that you
reset (re-initialize) the printer. To do this:
Press and release SEL to take the printer off-line.
The SEL light goes out.
Hold down the SEL key and press the LOAD/EJECT
key.
Important!
Pressing LOAD/EJECT re‑initializes the printer, but
does not affect any menu settings and does not reset
the printer to the factory defaults. For information
on resetting the printer to the factory defaults, see
“Resetting the Menu to the Factory Defaults” in chapter
