[Refresh Mode] DFU  
3516  While making prints with low coverage, t
he developer is agitated with less toner 
consumption and the toner carrier attracti on tends to increase. This may cause 
low image density or poor transfer (white dots). To prevent this, the coagulated 
toner or overcharged toner has to be  consumed by performing the refresh
