1. take off the toner bottle from the machine
2. print/copy while appears the "toner empty"
3. clean the developer roller, clean the waste toner unit, toner bottle unit.
4. change the sp modification
5. check the sp 2.001 (charge voltage) set the default 1.500 V !!!

Define "servicing the machine", as in all service consumables replaced, or a "open,vaccum out and clean" service ?


Make the following SP mode changes:

Are these not the changes that were suggested, before they decided to modify the developer roller to a new coating version ? Is it the old version dev roller or the modfied one in the 'B' ?
