Error code cf30 in toshiba 3511 what its mean and how can fix it
(CF30) - Reference plate detection voltage abnormality: The output
value of the color auto-toner sensor against the reference plate
is out of a specified range at the light amount correction during
an auto-toner adjustment or when a print job has finished.
Your color auto-toner sensor and reference plate are located under the input tray cover on the left side of the copier when you are facing it. It is on a bracket that hangs down into the copier and sits close to the revolver inside the machine. It is an optical sensor and if either it or the reference plate get stained with toner it will give you this error message, you may attempt to clean them with rubbing alcohol.
This error message may also occur if the solenoid that drives the reference plate is faulty so you will need to check that as well.
I would sincerely recommend that you get an authorized toshiba technician to take a look at the machine for you as this is a fairly difficult problem to fix right.
