Yellow light on Toner light on) Cannot print a thing

If all the lights are blinking on your Fuji Xerox 203A printer, it is indicating a "Fatal Error" or "Unknown Error" that has occurred.
Here are some possible reasons and troubleshooting steps you can try:

1. Paper jam - Open the printer cover and check for any paper jams. If found, clear the jam and close the cover.
2. Toner cartridge issue - Remove the toner cartridge and check if it is empty or low. If so, replace the toner cartridge with a new one.
3. Imaging drum issue - Remove the imaging drum and check if it is damaged or has reached the end of its life. If so, replace the imaging drum.
4. Connectivity issue - Check the printer connections to ensure they are securely plugged in.
5. Firmware issue - Try updating the firmware on the printer to see if that resolves the issue.

If none of these steps solve the issue, you may need to contact Fuji Xerox customer support for further assistance.

Press the button until all the lights are on..then let go the button, this will reset your drum counter.

May be problem on mother board or toner unite.
If it self change toner .

the drum or toner LED? if it's the drum, then just press the button until all the LED are ON then let go and this will reset the drum..
if it's toner, you need to take out the toner and on the left side of the toner, there is a level, unscrew the 3 screws and turn the level to the other side, re screw the whole cover and install back to the printer, this will reset your toner, make sure there is toner in the cart.

take out the drum unit and clean it, normally when the drum unit is dirty with toner, it will give you error.

You get it 90-100 US dollar for any Fuji xerox sale center.

refer my other posting on how to reset the toner.
left side of the toner cartrige, unscrew and turn the level other side.

pls replace the sensor in the printer and also chk after replacing a new toner

In most cases cartridges have a special chip that remembers the toner cartridge serial number an amount of pages printed from it. This means, that even though there still might be some toner left in the cartridge, the chip's counter reaches it's predefined limit and informs printer, that the toner has run out. Just like that, suddenly.
It may also be the case, that the chip loses contact with the printer's electrical terminals - try reseating the cartridge in the printer. If that doesn't help, it's time to replace it I'm afraid.
Usually the printer will inform "toner low" for some time before it becomes "toner out" and refuses to print. If you get "toner low", then it's time to purchase a new cartridge to have it ready.

Managed to get it going ,pulled all the toner cartridge out and reset and all is sweet.....!
