Frequently Asked Questions
How does tray assignment change black consumption on the twin-tray flagship?
Most twin-tray setups dedicate one tray to plain documents — and that tray's work is black's work. Contracts, forms and records flow from the document tray while the second tray waits with special stock, so black consumption follows your plain-paper volume: up to 4,500 pages per cartridge at $32.65, about 0.73 cents per page.
Does this black fit other platform models?
Yes: HL-L8260CDW, HL-L8360CDW, HL-L8360CDWT, HL-L9310CDW, HL-L9310CDWT, HL-L9310CDWTT, MFC-L8610CDW, MFC-L8900CDW and MFC-L9570CDW One black serves the twin-tray flagship and its siblings alike.
Which tray should carry the high-volume document work?
The higher-capacity tray, so refills interrupt less — and because that tray's output is almost entirely black text, its pace is your reorder clock for this cartridge.
What does 4,500 pages mean across two trays?
The rating counts pages, not trays: every black page from either tray draws the same cartridge down. A legal-size document run from the second tray spends black at exactly the rate of a letter run from the first.
How do I keep the document tray from ever stalling?
Keep the spare with the paper stock, not in a distant closet — the person who refills the tray should be standing next to the next cartridge. At $32.65, a cabinet spare per machine is the professional setup.
What backs the cartridge?
One-year warranty and one-year free returns under our shipping and returns page — if it fades far short of its rating or the machine rejects it, it is replaced or refunded.
