After I have installed a new toner cartridge and printer is still asking me to install toner. What am I doing now?

SOURCE: 3100CN keeps asking to replace black toner tried 2 new catridges!

After installing the toner cartridge the replace toner message will reappear after the calibration sequence until you press the menu button on the front of the printer. After doing that the message goes away and you should be ready to print again.

I have a CLX-2160N and have just emptied my own waste toner container. (Disclaimer: not sure how toxic or environmentally friendly this is).
Emptied carefully and thoroughly (fine dust). Immersed in bowl of warm soapy water, and vigorous shaking to get nice and clean.
Shook all water out well, and dried off as much as possible. Reinstalled. Turned printer back on. Hey presto - seems happy.

SOURCE: MESSAGE REPLACE/ INSTALL TONER WASTE TANK EVEN THOGHT I HAVE REPLACE IT ON A SAMSUNG CLX-3160 FN

When this happened, I took the tank out and shook it out into a garbage can (do this outside and be very careful not to breathe the dust). I then took a shop vac and held the hose at the opening while blowing compressed air into the tank. Wiggle the air nozzle around and you'll get out 99% of the toner. Pay extra attention to the sensor optics (plastic bulges on the sides of the tank).These need to be clean since the printer knows when the tank is full because the toner blocks light shining from one side of the tank to the other

Reinstall the tank and be sure it is fully inserted. If they printer is still on, turn it OFF. Close the front door of the machine and turn it back on.

Continue printing.

you need to get into technical mode, simply press menu > # > 1 > 9 > 3 > 4 and then press ok tech should be shown on the lcd screen, now go to the menu and data setup, look for memory clear or clear all memory, it should ask you for a destination country, if you choose your country at this prompt and press ok it should accept the toner
