Check Menu / Activators Definition Tables The Check Menu contains a set of extensive tests that return measured mechanism parameters for comparison against stated limits. Refer to the table associated with each test for their normal operating ranges. In cases where insufficient baseline data is available, the results have been left blank. All results from tests that move paper through the system were collected using 24 lb. Bond paper. Note Often, just running the test will exercise a position of the sytem and provide useful motions for observation. Also, collecting 2 or 3 samples of the test data is recommended before deciding on a course of action. Many of the tests rely on mechanical positions and slight changes can effect the results. Ensure that the system is not out of paper, ink or maintenance kit life. The diagnostics routines are not designed to address all of these conditions consistently. If a test result differs significantly from the typical values defined in the following tables, check the entire system containing the problem component to ensure a problem within the system is not influencing the test results. The Check All selection will run all check tests, taking 1.5 hours to complete and is not for use by field technicians. Check / Activators Menu Head Maintenance Clutch Gathers data on the performance of the head maintenance clutch. R# Definition Typical Value Actions 0 Peak Power (watts) -0.1 to 0.8 Reports the profile max power value. 1 Average Power (watts) 2 to 6.5 Reports the average power during the constant portion of the profile. Deskew Clutch Gathers data on the performance of the deskew clutch coil. R# Definition Typical Value Actions 0 Peak Power (watts) -0.1 to 0.65 Reports the profile max power. 1 Average Power (watts) 2 to 5.3 Reports the average power during the constant portion of the profile.
