High-yield black toner four-pack

This LD Products T640 multipack contains four remanufactured black cartridges rated at 21,000 pages each at five-per-cent ISO coverage. It is built for offices and home users who run a Lexmark T640 and want a lower-cost alternative to the original 64015HA supplies.

Remanufactured cartridges replace OEM units

Each cartridge is a rebuilt replacement for the Lexmark 64015HA high-yield toner, so the printer reads it as a standard consumable without extra software or chips. The pack delivers the same page yield per unit while reducing the per-page cost for high-volume mono printing.

Direct drop-in installation

Insert each cartridge into the T640 exactly like the original; no firmware updates or reset procedures are required. The main risk is using the toner in printers outside the United States or Canada, where regional locking can prevent recognition.

Questions about this item

What maintenance will the LD Products T640 toner cartridges need after the 21,000-page yield is reached?

Each cartridge is rated for 21,000 pages at 5% coverage. Once that yield is reached, the cartridge must be replaced with a new one; no internal parts are user-serviceable.

Which limit appears first during continuous printing with these cartridges?

The page yield of 21,000 pages per cartridge at 5% coverage is the primary limit; print density and coverage variations will determine actual life.

How much heat or noise do the LD Products T640 cartridges add when the printer runs all day?

The cartridges themselves generate no noise or heat; all sound and thermal output come from the Lexmark T640 printer mechanism during operation.
