Recommended For

• Ricoh IM C300F, IM C400F, or IM C400SRF owners replacing the black toner bottle; Ricoh lists this cartridge for those three models.
• Office teams that regularly print black-and-white documents on one of the compatible Ricoh MFPs and want a listed yield of 17,000 pages at 5% coverage.
• Businesses replenishing the black toner in a shared color MFP that handles both monochrome documents and color jobs; this listing is for black toner only.

Real-World Use Scenarios

• In a small office printing routine items such as letters, forms, and internal reports, this black toner supplies the text and other black areas; the 17,000-page yield rating is based on 5% coverage, so actual replacement timing depends on print content and volume.
• When a shared team uses an IM C300F, IM C400F, or IM C400SRF for everyday printing and copying, this genuine Ricoh bottle is the compatible black-toner refill for that device.
• For recurring black-and-white paperwork—such as invoices, schedules, or office notices—keeping this toner on hand can help the office replenish the printer without substituting an incompatible cartridge.
• When staff print color documents that also contain black text, charts, or labels, this cartridge supplies the printer’s black toner while the compatible MFP handles the color job.
• For a team with steady document-printing needs, the rated yield can help estimate toner planning: Ricoh lists 17,000 prints at 5% coverage, though pages with heavier black coverage may use toner faster.
