Frequently Asked Questions

Which toner does the Lanier LD540C use?

Are the cartridges on this page original or compatible?

The cartridges on this page are compatible replacements for the Type MP C4000 family (OEM references 841284–841287), built to match the originals' fit and page yield.

How many pages does each Type MP C4000 cartridge print?

The black cartridge prints approximately 23,000 pages; each color cartridge (cyan, magenta, yellow) prints approximately 17,000 pages, all at 5% page coverage — the ISO standard measurement for toner yield.

What is the difference between single cartridges and the color sets?

Single cartridges let you replace only the color that ran out. The 4-color sets bundle one cartridge of each color at a lower price than buying them separately — ideal when several colors need replacing at once.

The Type MP C4000 cartridge family is shared across the Lanier LD540C, LD550C, LD645C and LD655C, the Ricoh Aficio MP C4000/C5000, and the Savin C4040, C5050, C9145 and C9155.
