I have purchased machine Aficio 410C. Ones the main power is on it shows error SC542. It should not be solved. Once we clear the error code also. After few seconds it shows same error. Please help us.

That is a fuser fault code will need to repair fuser first. If you buy the fuser might come with instructions to reset code.

go to maintenance mode. press clear/stop press 1 0 7 and start key(hold) until maintenance mode is displayed. look for fuser SC reset.

This is the correct solution to resolving SC542 error on a Ricoh SP3410 SF and SP3510SF:
Press Clear/Stop button once and then press 1 0 7 and then the Start button to enter the "Engine Maintenance" in Maintenance Mode. Select "Fuser SC Reset" and execute..press ok. Turn main power on and off. Issue will be resolved.

I found some information on this error at http://www.fortc.com/2007/06/17/ricoh-cl4000dn-error-code-sc542/

According to this website, the error code is due to a fuser temperature problem.

To clear level A SC codes such as this SC541, you need to
Enter SP mode, and then turn the main power switch off and on, only.
Please check if the thermistors are the proper ones and are installed correctly in their position properly.
This is also useful for SC542.
Please check the thermostats and fusing lamps for open circuit.

Good luck and please rate me, thanks.

Press the red CLEAR/STOP key till you hear the little beep. Press 1 0 7 Press the green COLOR START key. The display changes into MAINTENANCE MODE Use arrow keys to go to ENGINE MAINTENANCE and hit Ok Use the arrow keys and select FUSER SC RESET and hit Ok Hit OK again at the Execute prompt.
Once it is done executing the reset, power the unit off and on.
If the error comes back again, it is likely a real hardware problem and you may need to replace some components.

SC542: Fusing temperature warming-up error The fusing temperature does not reach the fusing standby temperature within 135 sec (35CPM machines) or 145 seconds (45CPM machines) after the main power switch is turned on. - Possible causes - • Fusing thermistor defective or out of position • Fusing lamp open • Fusing thermofuse open • BICU defective • Power supply board defective • Poor fusing unit connection
Sometimes by going into service mode and then turn off copier and back on will clear this message or while in service mode do an error clear. But most of the time it is the thermistors in the fixing unit needs to be cleaned or replaced. I would probably call in the techs.

A SC542 error is a fuser problem. Did you have a power problem? You can try to reset it by turning the copier "ON" and once you have the code displayed on the screen.... Press the Yellow clear botton once - then the #'s 1 - 0 - 7, one at a time then press the Red Stop botton till the display changes..... Once, it changes turn the Main Power Off, not the one on the control pannel. Then turn it back "ON" and that should take care of it for you.... If it did not, you may have some more problems that can not be reset till they are repaired.. Good Luck

Try this !
Press yellow "c" buton, type 107 and then press and hold the orange "c" button for 3 seconds.
You will hear a "bip" and the machine should enter the SP mode.
Now just turn off the main power switch located on the left side of the machine. Turn it on again and see if the error appears again.

Hi first you have to check the fusing unit and all give you how to reset the error enter the sp mode c 107 ca then use the sp np 5-801 then pres okouble-
