Sindoricoh introduced the LP 4000 in October 2010, with an OEM-rated print speed of 38 pages per minute (ppm) and a duty cycle rating of 80,000 pages per month.

The supplies set is made up of separate toner cartridges and drum units. Replacement toner cartridges are available in 9,000 page yield and 15,000 page yield versions that require chips for the printer to function correctly.
