ADJUSTING PRINT QUALITY AND SPEED

Measuring performance

You can use the DocuPrint sequencer log file to calculate print speeds. Although a stopwatch is the recommended method for obtaining sustained throughput print speeds, the sequencer log can be used to calculate speeds which include the start-up latency associated with the printer. This section describes how to calculate speeds using the sequencer log and how to minimize the start-up latency in your calculations.

Note: The sustained throughput using a stopwatch is a better measurement of the speed of the job since the several seconds of start-up time do not need to be measured.

Refer to the following example when reading “Calculating throughput.” The Show Log command in this example displays a menu of logs with the current sequencer log named DocuPrint sequencer:
