38134 Main Plot Control MPC: Multiple plates detected on drum Gravure Japanese_Newspaper_OEM_Engine Lotem_400_Fiber_Head_Machine Lotem_800_Fiber_Head_Machine Lotem_Quantum Magnus_400 Magnus_800 Magnus_VLF Slave_MCE_Firmware Thermoflex Think_Motion_Controller Trendsetter_400/800 Trendsetter_NEWS Trendsetter_Series_4 This error is reported if the firmware measures a thickness much larger then expected during the focus learn before plotting. The thickness error measured is displayed at MPC Service verbose level. Enter the command 'verbose user service' or 'verbose service mpc' to enable. If this error comes up with only one plate on the drum, check the head alignment. Re-align if possible. Otherwise, adjust the 'focus BaseThickness' parameter to offset the alignment error. Lowering this value will decrease the error; setting it to 0 will disable multiple plate detection entirely. Try another plot with this new value to make sure a low thickness error is reported. The media thickness calculation is based on the average lens position determined by the head. The thermal 1.7x heads return a value relative to a 305 micron plate. The thermal 2 heads return a value relative to the media thickness used to install the head. If a media thickness other than 305 micron (0.012") is used to install the head, the 'focus BaseThickness' parameter must be set to the thickness of plate used to install the head. If focus learn is not done, then the average lens position is monitored during plotting, and is checked at the end of the plot. If this reading indicates that multiple plates were loaded on the drum, then the firmware will suspend before unloading the plate(s) This most likely indicates that two plates were stuck together during loading. Select the EJECT button to unload the plate(s). If plates are stuck together, fan all the remaining plates in the bay to separate them. If plates are not stuck together, then please call your service provider for more information. This error is reported. The picker grabbed two or more plates at a time from the bay during loading. The head may be out of alignment. The plate thickness may not be set properly. (Thermal 2) Head installed based on non-305 micron plate, but the 'focus BaseThickness' parameter was not adjusted accordingly. 18-Oct-2002 ../prm/mpc_focus_basethickness.xmlPRM: focus basethickness ../prm/mpc_focus_learnskip.xmlPRM: focus learnskip ..\..\ShowAllErrors.htmFirmware 1 Error Index ..\..\ShowAllCommands.htmFirmware 1 Command Index ..\..\ShowAllParameters.htmFirmware 1 Parameter Index Updated: Thu Jul 17 07:23:10 2008 PST
