Parallel 1 strobe adjustment (Par 1 Strobe Adj)
Note: This setting appears only if the printer has a parallel port available in the PCI slot 1.
This setting enables the servicer to adjust the amount of time the strobe is sampled in order to determine if valid
data is available on the parallel port. The range of values is -4 to 6. Each time this value is incremented by 1, the
strobe is sampled 50 ns (nanoseconds) longer. Each time this value is decreased by 1, the strobe is sampled 50
ns less often. When the value of this setting is 0, the factory default is used to determine the length of time the
strobe is sampled. If the servicer, for example, decreased the value from 0 to 3, the strobe will be sampled for
150 ns longer than the factory setting.
