SC 548 - Fusing unit set error or fusing unit installation error,differ to copier models.Try reset by open/close the front door or enter in SP mode and turn ON/OFF the copier.

sc220 is a laser sync error. You'll probably need to either replace the laser sync board or the laser diode itself, so you may want to contact a local service technician, as both of these components are internal and can be slightly tricky to get to.

The PCU is the drum unit. There is one for each colour (C,M,Y & K). Each PCU has a 'life' and the machine will ask you to replace it when it has reached the end of its expected life. The PCU life has nothing to do with the amount of toner that you have in the cartridges and they need to be changed independantly.

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

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.

Hello wajidsn

SC548 : "Fusing Installation Error.Fusing Unit Set Error"

It's the fuser. You can try turning it off, wait 30 seconds, and turn it back on again.

If the problem continues, call a technician in to get the thermistor replaced.

It's a common error.
