The Ricoh error code 548 / SC548 is a fusing unit error code. If you are getting this error: Check the fuser unit to see if it is set properly. There are some connections on the fuser unit not making good contact.

There's a video showing how to clear SC error codes: Resetting Ricoh Savin Lanier SC Error Code There's also a discussion here: Thread Ricoh Aficio 220 error SC392

If you can tell that the fuser is trying to heat up then you are going to have to replace the thermistors. The thermistors or thermisters are 2 parts in the fuser that "read" the fuser temperature. When 1 or both go bad then the machine can not "see" the heat and thus throws the code. Ricoh's in particular have more issues with the thermisters than other brands. Here is a link to a site that has the thermistors and a picture of what they look like.
Good Luck and Thank You for using Fixya.

Hi, there's no sc342 listed in the service manual, and I've never seen that code in years working on these machines. Are you sure it's not a different code, like sc542?

sc 548- service call - fusing unit not set properly
the fusing unit connector may be loose.
u can reset the error by entering the service mode (careful -do not change anything )
to enter the service mode press [all clear](yellow button) ,[1],[0],[7],[clear](orange button)and keep the button pressed for about 5 sec.
go in copier options , then mode 5, then option 810
and execute(or 1 & ok)

(careful -do not change anything else)

• Fusing thermistor defective or out of position
• Fusing lamp open
• Fusing thermostat open
• Poor connection of the fusing unit
Inspect all the elements before mentioned, soon presses total clear (Yellow Key) 1 0 7 and Maintain pressed clear stop key (orange key) more tan 3 sec. Enter SP 5-810 (SC code reset),
select execute, select close. Exit SP mode, turn the main power

If the problem continuous the problem can be in the Power supply board, can be defective.

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

good luck

That is fuser code and needs to be reset in the service mode, it will not go away by turning the off and back on.

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.
