Aficio MP C4503
Departments that live in color are the audience for the Ricoh Aficio MP C4503, a 45-ppm-class color multifunction fed by extra-high-capacity toner. Black is the 841849, rated up to 33,000 pages, while yellow 841850, magenta 841851 and cyan 841852 are each rated up to 22,500 pages. Compatible cartridges for the MP C4503 — singles, color sets and bulk packs — are stocked on this page.
Capacity is the theme of this generation: cartridges rated in the tens of thousands of pages mean the supply closet, not the machine, sets the rhythm of the workweek. A department can run long stretches of reports, decks and handouts between cartridge changes, and when a change does come due, each color swaps independently so the machine is down for minutes, not for a full set replacement.

Which cartridge should you buy?
There is no standard-yield tier to weigh here — every cartridge in this family is extra-high capacity — so the real decision is format. The black 841849 at up to 33,000 pages is the anchor: buy it singly for a quiet machine, or in 2-, 3- and 5-packs where monthly volume is serious. Colors at up to 22,500 pages each are best replaced one at a time as they empty. The four-color set fits a planned full refresh, the three-color set fits the moment just after a fresh black went in, and the five-, six- and eight-piece bundles serve offices that stock for several machines in one order.
Chip, toner and everyday use
Read the ratings with the 5% coverage yardstick in mind: a page carrying a full-bleed photo uses many times the toner of a memo, so color life varies with what your department actually prints. Store spare cartridges flat in a cool, dark cabinet and leave the packaging sealed until the day of the swap. If a cartridge near its end starts printing unevenly, a gentle side-to-side rock redistributes the remaining toner and often evens the output out for its final stretch.
Frequently Asked Questions
Which toner does the Aficio MP C4503 use?
Black 841849, yellow 841850, magenta 841851 and cyan 841852 — an extra-high-capacity set shared with the MP C4504, MP C5503, MP C6003 and MP C6004.
Is the 841849 a high-yield cartridge?
Yes — it is rated up to 33,000 pages at 5% coverage, the extra-high-capacity black for this family, which is why there is no separate standard-yield black to choose between.
What happens when only one color runs out?
Only that cartridge needs changing. Each color is its own listing — yellow is 841850, magenta 841851 and cyan 841852 — so the other colors keep working untouched.
Do you sell a full set for the C4503?
Yes. The four-color set replaces every slot at once, and three-, five-, six- and eight-piece bundles are listed above for partial refreshes and deeper stocking.
