Retrofit Information
We have been informed that some field technicians might not have installed the fusing
thermoswitch bracket properly. As a result, service code #E52 may be displayed because
of an incorrect gap between the thermoswitch and the hot roller.
To prevent this, a note on thermoswitch bracket installation has been added to the
"FUSING THERMOSWITCH REPLACEMENT" procedure. Please correct your service
manual page 5-77.
