I am new to these machines. I havent worked on cannon MFP's previous to this (so please excuse my limited knowledge on this type of machine, ). I replaced the black toner on one of these machines today. when i dropped down the front cover it was quite dirty inside, so I gave the internals a clean. I removed the waste toner box and cleaned this too. Nothing major just a quick wipe of a cloth. When I closed up the covers the machine keeps asking to refit the waste toner box. I have tried fitting a brand new waste toner box but it still wont clear the message. I hope I am missing somthing obvious.
Thanks in advance for any help.
