Paper Path Drive (Test ID # 5)
- This test runs successive pieces of paper through the media
path at low current levels to determine the minimum drive current. Due to the nature of the test
the last sheet results in a paper jam, and in some cases causes engine firmware to halt. By
counting the number of sheets that were tried, including the sheet that jammed, you can
interpret the test results (number of sheets is equal to scan cycles).
