Paper Path Timing (Test ID# 17 and 4)
- This test reports the timing from one sensor or event
to the next sensor in the paper path. The results are broken into two ID’s: 17 includes pick
events from all trays up to the standard ick sensor, ID 4 coves the remaining paper path
sensors. In the case of the Preheat entry sensor to the A width sensor the locations are so
close that skewed paper may result in negative timings.
