30.1.2= A jam has occurred in the ADF. Recommend action, turn the MFP off and then back on to try to clear the message.
If the message indicates that a jam has occurred, clear the jam, if the message is still there. Check that the cable between the print engine and the scanner is secure..
Turn the MFP off, remove all memory DIMMS or third party DIMM from the MFP (Do not remove the firmware DIMM) remove all EIO device from the MFP. Turn the MFP on
if the erropr no longer exists, reinstall each DIMM and EIO device one at a time, make sure to turn the MFP off and no again as you install each device. replaced a DIMM
or EIO device if it cause the error, if problem persists upgrade the firmware before replaced the DC controller. Replaced the formatter and calibrate the MFP.

Feedroller on mdf on xerox 5675 keeps jamming. The copier has done over 200,000 copies so I'm assuming the feedroller needs changing but as yet no message has appeared to do so. Any advice?

You are right, the feedroller is worn and needs to be replaced. Is your copier in an office or your home? Is it a copier bought by you personally or by your company? The reason for that is, Xerox never sells copiers to businesses without pushing a maintenance agreement on the customer. With that, there is an 800 number in the user manual for service and sometimes the number is posted on the copier. Unless you have a tech available to order and replace parts, you will have to call Xerox.

The flashing lights are a "Maintenance request error" or a "Fatal error". Most of the time it is a "Maintenance request error" which means the waste ink pads need to be serviced. You can reset the waste ink counter but the ink pads will need to be serviced at some point.
Use the Service option from Printer Properties to start service--maintenance----or you need to service your printer from vendor.....
