44536 Exposure Head Interface EHI: The Thermal 1.0 or Thermal 1.7x exposure head was unable to learn focus Gravure Japanese_Newspaper_OEM_Engine Lotem_Quantum Magnus_400 Magnus_800 Magnus_VLF Slave_MCE_Firmware Thermoflex Think_Motion_Controller Trendsetter_400/800 Trendsetter_NEWS Trendsetter_Series_4 Before every plot, the focus servo must learn the drum profile. This is done to guarantee that the first swath imaged will be in focus the first time. Cancel the job if possible. Check that the plate does not have any large dents in it. Try another plate, if not successful, call service. This error is reported. Head was not installed properly. Plate not loaded on drum properly. For example, there is a large bulge near the leading edge clamp. The plate is not cut even on the edge detect side. The focus is having to learn on/off the plate. This is not an ideal situation. There are large dents on the plate. Drum speed is too large. 11-Jul-2002 ..\..\ShowAllErrors.htmFirmware 1 Error Index ..\..\ShowAllCommands.htmFirmware 1 Command Index ..\..\ShowAllParameters.htmFirmware 1 Parameter Index Updated: Thu Jul 17 07:23:40 2008 PST
