F2-31 is related to the image process control for the drum. The drum sirface is read by the image density sensor - if it has a problem doing so then it will give this code. Possible causes could be a bad/old/worn drum or the drum is not being cleaned properly by the drum blade. To run the processor control adjustment do the following : press the "P" key then "*" key then "C" key then "*" key again. this will bring you into service mode. (warning : please do not make any other adjustments in this mode as you can do some serious damage to your copier). then type 44 and press start key then 2 and start key again. Once it is finished running restart the copier. If this fails you need to look at the drum and possibly change it.

H5 flashing on the display, anyone tell me what the error is please? It's a Sharp AR-161 copier

H5 doesn't show up on the service code manual. However, all error codes beginning with 'H' are related to the fuser, this is the heating portion of the machine. Be careful if it still prints despite the error code, you may damage the unit. It should be looked at by a service rep.

With a Sharp AR-M550U copier getting a CE-03 error when trying to email an image. Any suggestions on what the problem might be.

It means the copier is having ttrouble accessing the network resources to send the email. If you are still able to print to the copier without any problem then the issue will be with your email setting on the copier. Check to make sure you have the correct SMTP server info and the DNS and Domain info. Your email connection may also need authentication. If any of this info is incorrect it will give you this error. Was it working before ? Has your service provider or you changed your email information?
