Frequently Asked Questions

How long will a four-pack last on a printer that works this hard?

The pack holds 24,000 rated pages. On an MS621dn printing around 3,000 pages a month, that is roughly eight months of output; at 2,000 a month it stretches to a full year. Buying four at once converts toner from a recurring errand into a twice-a-year planning item.

What does the per-cartridge price drop to in this pack?

To $161.08 per cartridge — $644.30 for the pack, which is $55.46 less than four singles at $174.94 each. That is the best unit price available in this standard-yield cartridge line. The saving comes purely from pack size; the cartridges themselves are identical to the single.

Which models can draw from this four-pack?

Any printer on the platform list. The listing is titled for the MS621dn, but the 56F1000 is the common cartridge for MS321DN, MS421DN, MS421DW, MS521DN, MS621DN, MX321ADN, MX521ADE and MX521DE as well. A four-pack can therefore feed the MS621dn and its platform siblings from one shelf, with no model-matching headaches for whoever keeps the stockroom.

Is it risky to commit to four cartridges if we later replace the printer?

Less than it first appears. The cartridge fits the whole platform, so a successor machine from the same family keeps using your stock. And if plans change entirely, unopened cartridges are returnable free within a full year of purchase, which gives a long window to change your mind.

What storage setup suits a pack this size?

Keep the boxes sealed and flat in a dry, room-temperature space, out of direct sun and away from heaters. Mark each box with its arrival date and install oldest first. Stored that way, sealed toner stays ready for years, so the fourth cartridge performs exactly like the first.

What cover comes with a bulk purchase?

Every cartridge in the pack is individually covered by a one-year warranty, and returns are free throughout the first year. One weak unit does not affect the status of the other three. Our shipping and returns page explains the process, and support is on hand Monday through Friday, 9 AM to 5 PM CST.
