Has anybody out there had this code? It's a first for me. I replaced the thermostats and thermistor- no joy. Any ideas please???

this code states the pressure roller lamp stays on for more than 120 sec. have you checked the thermostat and lamp for continuity? if there is continuity, then check for supply voltage to the lamp it might be the psu. good luck.

In the end a whole fuser went in, still the code came up. psu is an expensive option!

This is from the Goose Guide..

SC565
*Heat lamp consecutive on error - Broken main fuser connection
*Heat lamp consecutive on error - Check HR thermistors with SP1-106 001 (ctr) and 002 (ends)
*Heat lamp consecutive on error - Heat roller lamp defective
*Heat lamp consecutive on error - Power Supply defective

Obviously it's not the fuser parts if it has been replaced, but maybe the connector or power supply.

a psu is expensive but if it turns out to be the psu there are repaired psu which can be half the price of new.

I have replaced the PSU for this issue in the past. Hytec does our board repairs at substantial savings from OEM cost.
