Aficio MP 4054SP
Departmental black-and-white volume is the Ricoh Aficio MP 4054SP's home ground: a full monochrome MFP for print, copy, scan and fax that treats toner changes as rare events. It runs the MP 4055 cartridge family — the 842126 black cartridge, an extra-high-yield unit rated for up to 37,000 pages. This page carries that cartridge as a single, a 2-pack and a 4-pack for the supply shelf.
A cartridge rated at 37,000 pages changes the economics of a shared departmental machine. Instead of a monthly chore, toner becomes a line item reviewed a few times a year, and the cost-per-page conversation gets much simpler for whoever tracks the department's budget. The MP 4054SP typically anchors a workgroup's document flow — statements, reports, case files — so the practical question is rarely which cartridge to buy. It is how many to keep within reach so the machine never waits on a delivery.

Which cartridge should you buy?
Start from the yield: a single 842126 already covers up to 37,000 pages, which for many departments is a full quarter or more of output. Buying singles keeps inventory lean and suits a site with one machine and predictable volume. The 2-pack earns its place when the MP 4054SP cannot be allowed to sit idle — one cartridge in the machine, one in the cabinet, and a toner-out message becomes a two-minute swap instead of an urgent order. The 4-pack is the facilities choice: offices running several machines from this family, or a central stores that supplies more than one department, get the lowest cost per cartridge and the fewest purchase orders to raise. There is no smaller standard-yield alternative to compare against; every option on this page is the same extra-high-yield cartridge, so the decision is purely about stock depth.
Chip, toner and everyday use
These are large cartridges: lift with both hands, keep the unit level, and draw the sealing tape out in one steady pull before fitting. The fitted chip lets the MP 4054SP report toner status accurately, which matters on a shared machine where nobody owns the supply cupboard. When the display warns that toner is running low, the rating system means there are still many pages left — use that window to confirm a spare is on site rather than waiting for the hard stop. Store spares in a cool spot away from radiators and sunny windowsills, and rotate them oldest-first so no cartridge sits on the shelf for years.
Frequently Asked Questions
What toner does the Ricoh Aficio MP 4054SP take?
It takes MP 4055-family black toner, part number 842126 — also referenced as 841999 — rated for up to 37,000 pages. The single, 2-pack and 4-pack above all contain that cartridge.
How long will a 37,000-page cartridge last a department?
It depends on volume and coverage. A department printing 3,000 pages a month at standard coverage could see the better part of a year from one cartridge; heavier coverage on reports and forms shortens that. The rating is measured at 5% coverage.
Is this the same cartridge the larger models in this family use?
Yes. The two larger models listed below share the same MP 4055 cartridge family, so one stock of 842126 cartridges can supply all three machines.
Are these OEM Ricoh cartridges?
No, they are compatible replacements built to the 842126 specification, quality-tested, and covered by a 1-year warranty with 1-year returns.
