Hello.
That error is related to TD sensor error.
I advise you to call a trained Technician

SC390: TD sensor error

- Possible causes -

· TD sensor abnormal
· Poor connection of the PCU

SC390 TD sensor error The BICU detects the TD sensor outputting abnormal voltage (less than 0.2 V or more than 4.0 V) 10 times consecutively. • Defective TD sensor • Loose connection of the PCU
you may need a new PCU unit

SC548: Fusing unit installation error - Definition - [A]
The machine cannot detect the fusing unit when the front cover and right cover
are closed.
- Possible causes -· Fusing unit is not installed
· Poor fusing unit connection


check the 2 sensors on the left hand side of the copier (as you look at where the fuser is located). These get knocked & moved out of postion,
this sc 548 usually happens when paper jam occurs and user does not properly fit the fuser... also not fiitted properly due to some foreign object in between fusing belt and the sensor...
Enter SP 5810 (SC code reset), select “Execute”, select “close”, exit SP mode then turn main power switch off and on.
to enter SP mode press yellow C button press 1 0 7 on numeric keypad and then hold down the orange C button from the menu select copier SP then type in 5801 and press # selest execute then power off and back on. Your machine should now be working. Hope this helps. if this doesnt solve ur problem then try contacting ur ricoh service tech
