Ricoh 821257 Magenta Toner Cartridge 34000 Pages

Genuine magenta toner for SP C840 and SP C842

The Ricoh 821257 cartridge is an original OEM supply built for the SP C840DN and SP C842DN colour laser printers. It delivers magenta output for office documents, presentations and graphics that require consistent colour accuracy. Offices that standardise on genuine consumables use this cartridge to maintain print quality and avoid compatibility issues.

Rated yield of 34000 pages under continuous printing

The cartridge is rated for 34000 pages at standard coverage, a figure based on sustained printing rather than short test bursts. In daily use the toner maintains even density across long runs, reducing the frequency of replacements and keeping workflow interruptions low. Colour balance remains stable from the first page to the last in the rated lifecycle.

Direct drop-in installation with minimal error risk

Installation consists of opening the front cover, removing the empty magenta unit and sliding the new cartridge into its keyed slot until it clicks. The printer recognises the genuine chip immediately, so firmware conflicts or “non-genuine” warnings do not occur. The only common issue is forgetting to remove the protective seal before insertion, which causes a temporary print-quality alert.
