Problem started out with an H4 error - I did the steps to reset as stated here on this site. Upon resetting the machine, I now have a CH error showing - What to do now?
I refilled toner for sharp sf7850. I use the program command c, interupt, 0 , interupt, 25, press print key. It gave me EU error. Please how can I resolve this problem
CH - open cover in the paper feed area.OR - Sorter not installed properly CH blinking - Dev unit is not properlyinstalled.
EE-EU - Low toner density in thedeveloper.
Check/ replace toner cart. Check/ reset Dev. unit. Check covers and doors to make sure all are closed properly. If you have sorter -- make sure sorter is seated properly.
