Waste toner is almost full on Ricoh aficio AP3800C

open front door. lower left empty the waste toner. -carl

turn off the printer and open the front door and check at the left corner of the lower part you will see a white can slip it gently out to where there is no fire and gently pour the waste out from a hole out may into a bag and dispose there after replaced the can to its position, close the printer and turn it on again.

Open the main front cover and you will see the white plastic waste toner bottle on the left hand side halfway up. I lies on its side and you can see the bottom of it.

Slide it out gently keeping it level to avoid spilling all the waste toner.

Either replace with a fresh empty waste bottle or empty the bottle into a large plastic bag you can keep sealed with the bottle inside while you shake it.

You have a good chance of spilling the toner all over your clothes if you are not carefull and note that the waste toner IS HIGHLY INFLAMMABLE so no naked flames nearby!!
