You have to reenter the configuration ID until a valid ID is verified. • If the ID is valid then the ID is saved in NVRAM and the printer automatically PORs to activate the new setting. Note: When the printer PORs it does so in the normal mode. Parallel Strobe Adjustment This setting lets the user adjust the factory setting for the amount of time strobe is sampled. This determines whether valid data is available on the parallel port. Increasing this value means that strobe is sampled 50ns longer. Decreasing this value means that strobe is sampled 50ns shorter. The range of this setting is -4 to +6. Example of setting: • A value of 0 indicates no adjustment is sampled from the factory setting. • A value of -1 indicates the sample strobe time is reduced by 50ns. • A value of +3 indicates the sampled strobe time is increased by 150ns. 3-18 Service Manual
