Model: Xerox 7535/7545/7556 Series
Problem description: the screen displays "fixing system error";
When the machine has a "fixing system error", there are usually the following situations:
First, the motor failure.
Second, the motor drive board failure.
Third, MCU circuit board failure.
Fourth, fuser failure (310-330).
Five, the external voltage fault.
First, it is checked whether the voltage of the fuser and the currently used voltage match. 220V machines do not need to use transformers, 110V machines must use transformers, in addition, when the external voltage is unstable, it will also display "fixing system failure";
Secondly, when starting up, the left fuser can be identified by sound to see if it is normal. If there is no sound or abnormal noise, it is a motor failure. It is necessary to remove the fuser and rotate the gears on both sides of the fuser to see if the resistance is normal. Identify whether the gears are damaged. If there is damage, it is necessary to replace or clean the gears and add gear oil to make the load normal.
If there is no damage, it may be caused by the large rotation resistance of the fixing film, and it is necessary to remove the fixing film for overall cleaning. Note that when cleaning gently, it is recommended to use glasses cloth and the like to do cleaning, can use the right amount of alcohol,
Finally, the fuser is an important part of the machine and is recommended to be carried out under the guidance of professionals.
