Reservoir Heater, Jetstack Left Heater, Jetstack Right Heater, Paper Preheater, Drum Heater, Ink Melt 1 (yellow) Heater, Ink Melt 2 (cyan) Heater, Ink Melt 3 (magenta) Heater, Ink Melt 4 (Black) Heater (Continued) This test sequentially applies power to each of the heaters to verify the relationship between power applied and heating/cooling and to check the current drawn by each heater. Test results are derived for each heater. When information about a specific heater is requested, all of the heaters are tested as a group, and then the data for the specified heater is reported. R# Definition Typical Value Actions 5 Peak Temperature MFG (deg c) Only 6 Peak Temperature MFG Time (ms) Only 7 Final Temperature (deg c) MFG Only Reports the peak temperature after the heating interval ends. Normally the beginning temp would be subtracted. Indicates how much heat was produced during the heating interval and propagated to the thermistor. Reports the time following the application of power to the specified heater until the peak temperature is reached. Shows the rate at which the thermal pulse propagated through the intervening structure. Reports the final temperature at the end of the test. Note, for each heater this is a different time from heater power application. This value could be more effected than others by cross talk from other heaters (and the chassis generally warming). Shows the heat dissipation at the thermistor during cooling. Might indicate problems with airflow. 4-26 WorkCentre C2424 Service Manual
