Our take
Ricoh's SP C840DN is a substantial color printer for an office that values rated speed, paper capacity, and standard automatic duplex. It is a more deliberate fit for a shared wired queue than for a home desk: the 1,200-sheet standard input and optional expansion help reduce refill interruptions, while the lack of a documented monthly recommendation leaves workload suitability less precisely bounded.
A wired office that needs color output, routine duplex, and more paper on hand than a small desk printer provides..
Choose another model if built-in Wi-Fi, copy or scan functions, a compact desk footprint, or a published recommended monthly range is essential.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- Ricoh rates both color and monochrome output at up to 45 pages per minute.
- Standard automatic duplex and 1,200-sheet input support larger routine print jobs.
- Gigabit Ethernet and optional paper expansion make the model configurable for a shared office.
What to weigh up
- Wireless is an optional configuration rather than a standard connection in the documented base model.
- Ricoh's checked U.S. source does not establish a recommended monthly workload range.
- The large standard paper capacity and office-oriented setup may be excessive for occasional personal printing.

Full review: how the features affect your choice
What the features mean for you
Match the exact C840DN configuration
Ricoh's U.S. datasheet identifies the SP C840DN as a color laser printer, and the candidate part clue is 408105. Keep that exact model name attached to the purchase: related SP C840 variants can have different finishing or paper configurations. This review covers the documented U.S. C840DN printer and does not treat a family photograph or broad Aficio listing as proof of included accessories. The model is print-only, so copy, scan, and fax work still needs separate equipment. Before purchase, compare the offered nameplate with the C840DN designation and confirm that the paper and network configuration matches the office plan.
Rated speed is suited to a shared queue
Ricoh rates color and monochrome output at up to 45 pages per minute. That specification makes the model relevant when several people send routine documents, but a rated maximum is not a promise that every graphics-heavy job will finish at the same pace. Color documents, first-page timing, and job setup affect the actual workflow. The useful distinction is that the C840DN is a fast print-only device rather than a multifunction center: it can take a print queue without adding copying or scanning functions the team may not need, while a team that needs those tasks should choose a different class of machine.
Paper capacity changes refill work
The datasheet lists 1,200 sheets as standard input, supplied through two 550-sheet trays and a 100-sheet bypass. Optional input can raise total capacity to 4,700 sheets. This gives an office a way to keep common paper available and reserve the bypass for alternate media, but the larger total depends on added equipment and should not be assumed to arrive with every offer. The standard capacity can be useful for a shared queue that prints throughout the day; for a low-volume user it can add bulk without solving a meaningful problem. Check the tray count and included options on the specific unit.
Automatic duplex supports everyday output
Ricoh specifies standard automatic two-sided printing, so the printer can turn sheets for ordinary duplex jobs without asking the operator to re-feed a stack. This is useful for reports and internal documents where reducing page count or handling matters. It does not add a document feeder or scan function, and it says nothing about how a particular used machine's duplex path is working. If duplex is central to the workload, inspect the paper path and test a two-sided job on the unit being offered. Buyers who only print occasional single-page documents may not benefit enough to justify this office-sized model.
Plan around wired Ethernet and optional Wi-Fi
The U.S. sheet lists Gigabit Ethernet and USB; wireless is an optional choice rather than a standard built-in interface for the base configuration. Ethernet is the clear fit when the printer will sit on a managed office network. A buyer who needs Wi-Fi should confirm that the correct wireless option is installed and supported before treating the machine as wirelessly ready. USB remains a direct connection, not a substitute for confirmed shared networking. The source does not establish that an individual used printer includes optional hardware, so check the actual unit and included modules instead of relying on a generic family listing.
Keep the workload claim within the source
Ricoh's reviewed U.S. datasheet does not provide a recommended monthly page range for the exact SP C840DN. That value remains unknown; speed and paper capacity are not substitutes for a maker's recommended workload. A high-capacity printer may handle larger batches conveniently, but that observation should not be turned into a monthly threshold or a claim about service life. The strongest fit is a color office that can use its documented interfaces, duplex, and paper capacity. If a numerical recommended workload is a must-have, compare a model whose exact U.S. source states one and verify the supplies and service plan separately.
Compare for your needs
Compare a smaller printer if capacity is unnecessary, or a sourced multifunction model if copying and scanning belong in the same workflow.

The decision
The SP C840DN fits a wired color queue that can use 45 ppm rated output, automatic duplex, and 1,200 standard sheets. Its optional wireless and undocumented recommended monthly range are the decisive limits.
