I’m giving away this brand new Lexmark C540X75G toner waste container. Compatible with printers C54x, X540, X543, X544 and many more according to the Lexmark website: https://www.lexmark.com/en_xm/supply/4584/Waste-Toner-Bottle#compatible-devices
It was meant to be used for a printer whose key components started to fail and were way too expensive to be worth the repair.
