How to resolve the code error for Sharp AR C262M


I found this for a different model in the same family. Sharp AR-BC320 it may be the same as your problem.

On page 2 it says E7-21 is:
LED controller initial trouble (Cyan)

On page 4 it gives a couple of things to try to fix the problem.

I have error code 51 and 21 on the printer. I


21 is "Page too complex"
51 is "Beam detect error" or "laser error"

My question to you is, does this only happen when you are printing a page that is very graphics intensive, or does it happen with simple jobs too? It could be that you just don't have enough memory in the printer to handle some of these pages. Then again, you may have to replace the laser scanner. I advise you to call a tech out to take a look at it rather than trying to fix this on your own.

If it isn't happening too often I'd probably just **** it up and live with it if it were me. If it is getting in the way of business though you really ought to call a tech. A lot of times these things can be fixed for a lot less $ than you'd think.
