Parallel strobe
This setting lets the user adjust the factory setting for the amount of
time strobe is sampled to determine that valid data is available on
the parallel port. Each increment of the strobe adjust value means
the strobe is sampled 50ns longer.
Perform the following steps to change the parallel strobe adjust:
1.
Enter the configuration mode. See
“Configuration mode” on
page 3-14
for more information.
2.
Perform a double button press seven times. This moves to the
parallel strobe item on the configuration menu. The parallel
strobe (Load Paper) light is blinking.
3.
The current parallel strobe setting is indicated by the
off/on/auto (Press Button) light. When the light is off, the parallel
strobe is set to normal. When the light is on, the parallel strobe
is set to +1. When the light is blinking, the parallel strobe is set
to +2. Perform a brief button press to select the parallel strobe
setting.
4.
Perform a long button press. All lights blink once, indicating the
setting is saved.
