Hi, I can't find that specific error code in the documentation on that model of machine, however, in general in Xerox machines U8-3 means that your exposure lamp is blown or has a problem

You can find your answer at the link below. Just type "memory full" in the search dialog box and it will provide you with the many results and solutions for clearing the error. The message can be the result of many issues, so you may need to perform a few different steps:

On this model, the heat roll has a temperature sensor. If the heat roll is worn and coated with toner, this will damage the sensor. Most common problem is this sensor goes out when a heat roll is badly worn. Circuit boards on this model are pretty reliable.
This sounds like a fuser rebuild.

You hopefully just need to clear memory, delete phone numbers or delete jobs.

If those don't work the Main Board might be bad 160K72560

Could be the tab that actuates the top cover switch is broken off.

The process unit is your drum,toner, and developer unit. It sits right under the top cover. Big black removeable cartridge.

this code means your scanner has failed to setup correctly. this could be a problem that you would need a qualified tech to service the copier. there is nothing that you can do after you power off and power on (popo) the copier. it could be voltage, pwb board, or a binding scanner assembly.
