Re: Savin C9025 SC565
[Symptom]
SC573 (Pressure roller overheat 4 (software error)) is displayed. After resetting the SC573, the machine operates normally only for a certain time, then SC565 (Pressure roller fusing lamp consecutive full power 3) is displayed next.
Note:
After resetting the SC573, the machine operates normally. But after 5 minutes, SC565 is displayed. After resetting the SC565, the machine operates normally for 5 minutes.
SC573: The detected pressure roller temperature stays at 230�C or more for 1 second.
SC565: When the fusing unit is not running in the ready condition, the pressure roller fusing lamp keeps ON full power for 250 seconds or more.
[Cause]
The pressure roller thermostat or pressure roller heater is disconnected.
[Solution]
Replace the pressure roller thermostat or pressure roller heater.
Note:
Because the machine can operate for 5 minutes after reloading, you can change the AOF setting to 1 minute as a temporary workaround. (Be sure to replace the part when it is delivered to you.) -
Re: Savin C9025 SC565
Pressure roller heat detection is via two contact type thermistors (centre/end).
I would check they are not dirty / out of position / faulty (temp display SP1106-003/004).
A incorrect low temp reading could lead to overheating and hence a hard thermostat blow.- Knowledge not shared, is eventually knowledge that becomes lost... like tears in the rain.
