Yes it is
Not really but when I switch it back on it is more of a grinding/ grating noise as if something is offline on a roller inside or is stuck. But the warning sometimes advises a "communication error" which would suggest this is not the cause of the issue
What should I be checking for?
I have done this now but the orange light is still on on the top next to the symbol that looks like a triangle with a lightening bolt through it.
No, the light goes green then something kicks in and the grinding noise starts again. and I just checked the area that I cleaned and it is covered in toner dust again.
