hola colega adj Prints Black and White Only Problem Jobs print out in Black and White (B/W), even the test page from the print driver. Test pages from the DC4 Print Pages menu also print B/W. The Cyan, Magenta and Yellow color plates are missing all together, it is NOT converted to gray scale. Only the Black data is present. Cause The DC4 lays down color from the drum to the IBT in this order, Yellow, Magenta, Cyan and then Black. The IBT Cleaning station is located right after the Transfer Station. If the cleaning assembly is cammed up during the print cycle, then this is what happens: Drum is wiped clean, Yellow is applied Yellow is wiped clean, Magenta is applied Magenta is wiped clean, Cyan is applied Cyan is wiped clean, Black is applied The image is transferred (now with only black ink) The problem is the cleaning system is stuck against the IBT when i should be cammed away. The camming action is caused by ramps which are located on the fuser tray assembly and are driven by gears in the assembly and controlled by a clutch in the same assembly. A xerox technical representative should troubleshoot the cleaning assembly ( saca la charola completa del lado izquierdo donde va el fuser y por debajo al fondo esta este emsamble a de estar y revisa por ahii ) saludos
