Aficio SP C420DN LP226cn

Two nameplates, one printer: this category covers the Ricoh Aficio SP C420DN and its LP-badged twin, the LP226cn — a networked, duplexing color laser built for workgroup duty. Both badges sit on the same Type 145 toner platform, so supplies cross over completely. The cartridge listed here is the black, 888308, a high-yield unit rated for up to 15,000 pages. The family's colors carry their own numbers in the same series — 888311 for cyan, 888310 for magenta and 888309 for yellow — and the full color range sits on the Aficio SP C420DN page linked below.

The dual naming trips up more buyers than the machine itself ever will. One fleet was bought through the SP channel, another inherited under the LP badge, and both sides of the office end up ordering what looks like different toner for identical hardware. It is not different. If your asset tag says LP226cn and the cartridge box says SP C420DN, you are still looking at the same Type 145 family — order by the 888308 number and let the badge go.

Which cartridge should you buy?

On this page the choice is simple, because the black Type 145 cartridge comes in a single high-yield class: up to 15,000 pages per cartridge. At that rating, even a busy workgroup changes black infrequently, and cost per page stays low without juggling pack sizes. Colors follow the same pattern across the family — each is its own cartridge, replaced only when it runs out — so a machine that prints mostly black-and-white with occasional color charts will work through several black cartridges before any color needs attention. For the color singles and sets, use the Aficio SP C420DN page below; every Type 145 cartridge there fits this machine exactly as it fits the SP-badged one.

Chip, toner and everyday use

The Type 145 cartridges are chipped, and the printer expects to read that chip at install — seat the cartridge fully and close the cover before sending a print run through. A 15,000-page rating is measured at the standard 5% coverage; ordinary letter-size text sits near that mark, while full-page color graphics will drain any cartridge in this family much faster. When density fades unevenly, rock the cartridge gently to redistribute the powder before concluding it is empty. Spares keep best sealed, flat, and away from windows.

Frequently Asked Questions

My printer says LP226cn — is 888308 really the right black cartridge?

Yes. The SP C420DN and the LP226cn are two names for one color laser engine on the Type 145 platform, and the 888308 black cartridge fits both badges.

How many pages does the 888308 print?

Up to 15,000 pages per cartridge at the standard 5% coverage used for yield ratings.

Where do I find the cyan, magenta and yellow cartridges?

They are the rest of the Type 145 series — 888311 cyan, 888310 magenta and 888309 yellow. The full color range, including sets, is gathered on the Aficio SP C420DN page in the family list below.

Is this an original Ricoh cartridge?

No — it is a compatible replacement with a working chip, built to match the original cartridge's fit and yield, and backed by a 1-year warranty and 1-year returns.
