Hello my name is***** do not rate until we are finished. I look forward to assisting and am very sorry to hear that you are having this problem. Is it the same number 5010 every time and not 5100?
I can not see the thread you read with Bernie, what have you tried? Or was just disconnecting and reconnecting the cables all you have done so far?
5010 is a scanner error and the scanner is actually used when you make a copy. It is normally caused by a wire issue. Are you somewhat handy? We will need to take part of the machine apart to try and fix this. You can not bypass this error.
Ok good, if you get stuck let me know, as long as you go slow you should be ok.
On the left part of the printer - there are 3 screws, 1 hidden by the gray plastic mask and two others in the back.
Remove these, the panel should come off after that but you will need force it a little, not to hard though as you do not want to break anything it should be clipped on with plastic clips.
Let me know once you have done that.
The left part of the printer itself. So if you are looking at either the front the left side, looking at the back the right side.
ok is it stuck?
It usually looks like a square tab. You can usually see an outline of it.
It should be outside of the printer.
It will be hidden under a small plastic tab. I do not have your model here to take a picture of but here is an example of what I mean used on a laptop.
That is odd there should be one hidden under a tab like that. Use a flashlight and try looking on the other side under the plastic you can lift, that may be able to help you find where the screw is.
It is a plastic panel on the left side of the printer it should not wrap around, though it should have a slight lip for both the back and front.
There is no diagram as I mentioned before, and I am sure because I have done it before many times. I work on these machines both on and off this site. I will opt out and open this to all others for you.
