On the copier:

SC548 AND SC990

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.

I quote from manual:

SC548: Fusing unit installation error

- Definition -
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

To reset try going in service mode and performing a reset.

To open service mode press [All Clear(yellow)] ,[1],[0],[7],[Clear(orange)]and keep holding down the clear button for about ten seconds.
When service mode starts, go to Copier Options , then choose mode 5, and option 810. Execute by pressing 1 and ok.
Do not change anything else in service mode, or you can cause more troubles.

If that does not clear the error , then there is a faulty part, in that case call service at the number listed in the user manual.

What is error code SC548 on RICOH Aficio 2035/2045 machine. Functional problem within the copier. How do i reset the copier to operate normal?

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.

I have problem with my copier aficio 450,sc548 appear,please help me solve this error

SC548 is a fusing unit installation error. The machine can not detect the fusing unit for some reason. Did you have the fusing unit out of the machine? Like to remove a paper jam? In case you do not know the fusing unit is the part that gets hot. Located right before where the paper exits the copier. It comes out the front of the machine when you have the front door open. If the front door is open it is in the upper right corner and should have a blue knob on it. Make sure this unit is all the way in. You also may have a wiring or connector issue causing this as well.
You will have to enter the service mode to reset this code.
CAUTION: Do NOT mess with this service mode in any way other than the specific function I give you. Doing so could result in damage to your machine!

Enter SP (service mode) by pressing yellow C button, then press 1 0 7 on numeric keypad and then hold down the orange C button, display will change and then from the menu select "copy SP" then type in 5801 and press #, then press "execute". Turn power off and back on. If the code is gone and the machine works then your fine. If it comes back you will need to call a servicing company and have them repair the machine.
Good Luck and Thank You for using Fixya.
