greetings, dear engineers, the Xerox 7760 does not come out ready, remains on the "heating of the thermoblock", the service is turned on, the temperature of the thermoblock is 105, the thermoblock is replaced with a known working one, there is an error 1023 in the manual I did not find a description, at the moment I suspect the operation of only one lamp, perhaps the temperature on the power supply does not work. Does anyone have such an experience?
