Waste Toner Collector Requirements
The Lexmark 20N0W00 waste toner bottle collects excess toner particles generated during daily printing operations. Rated for up to 15,000 pages, this essential component outlasts several standard toner replacements and ensures clean output without internal dust build-up.
Choosing the right toner setup for your workplace
If you print primarily routine correspondence, standard 20N30K0 black toners offer low upfront costs. For busy offices managing frequent reports and marketing materials, opting for 20N3XK0 and 20N3X colour high-yield toners significantly lowers overall printing expenses. We supply genuine Lexmark toner cartridges with full support under our Returns policy. Free delivery applies on all orders over $99, dispatched quickly from our warehouses in Perth, Brisbane, Sydney, Melbourne, and Adelaide.
Pro Tip
High-yield 20N3X series cartridges contain over four times the toner of standard 20N30 units while using the exact same physical slot, making them far more cost-effective for ongoing workplace printing.
Frequently Asked Questions
Can I mix standard 20N30 cartridges with 20N3X high-yield cartridges in the CX431adw?
Yes, standard 20N30 and 20N3X extra high-yield cartridges share the exact physical dimensions and fit into the same internal slots. You can run a high-yield 20N3XK0 black cartridge alongside standard 20N30 colour cartridges without any setup issues.
How do I know when to replace the 20N0W00 waste toner bottle?
The Lexmark CX431adw alerts you on-screen when the 20N0W00 container approaches its 15,000-page capacity. It is best to keep a spare container on hand so high-volume print tasks are not interrupted when the current waste collector reaches full capacity.
Why do 20N3X colour cartridges yield 6,700 pages while the black yields 6,000 pages?
Lexmark designs extra high-yield 20N3X colour cartridges (Cyan, Magenta, Yellow) with a higher page rating to match common office document workflows, where composite colour usage across charts and graphics depletes individual toner reservoirs at balanced intervals.
