Sc548 can generally only be reset by entering service mode, and generally is caused by a defective thermistor (thermostat) in the fuser, and/ or power fluctuations. Sc990 is a software issue. I'd consider a new HDD> You'll need a tech for these problems.

SC548 means the machine it not seeing the fuser unit. Open the Right side and front doors. Check the fuser unit to see if it is mounted properly.
There is some connection on the fuser module not making good contact. Reseat the fuser and power the machine off and on.
If you need to reset. Press Clear all, 107 and hold the pink button until you cee copy sp page displayed. Press copy sp, then while on that page turn the machine off and back on.

This a fuser (hot section) error code that need you to enter service mode to clear, -Carl

Press the UP and DOWN arrow keys together for 5 seconds or more, and then press the OK key.

Poor connection of the fuser, and the code will need to be reset in service mode.

Sp 1-902-001 set to 0. Let me know if this helps. -Carl

I have sc 548 error code also. I was following your instruction, but i couldn't enter to service mode. How do i prepare it? Please write this instruction to me step by step.

On the Ricoh 3713 you can do it on the main board by putting dip switch 101-1 on and then off, entering 97, and pressing the aps key. Then power cycling the printer.

The 3500 is probably similar.
