Hi,

The most common explanation for the error 'U4-2' in all the 'Xerox' machines is "Fuser warm up failure occurred". I am very sorry that such a problem has occured for you. It cannot be solved by you, if you are not a qualified technician and without proper tools.

Please do call the nearest service centre for a visit and they will probably solve it in a day. Remember, they need the service manual procedures for solving it properly.

Don't worry, it is a very common problem. But only authorised service people can help you in a good way.

Bye

:)

Have a nice time.

replace thermistor in fuser unit

your copier should be displaying a fault code, different codes need different reset codes - be specific
