Founded in 1960, Sindoh is a specialist manufacturer of office multifunction printers (MFPs), with the manufacture and sale of copiers, printers, and consumables forming the core of its business.
Its flagship products are A3 and A4 monochrome and color digital MFPs, and the company has long held a leading share of the domestic office MFP market. It operates overseas manufacturing bases in Qingdao, China (established 2003) and near Hanoi, Vietnam (established 2014) to secure cost competitiveness.
Beyond office equipment, Sindoh also offers office solutions that support efficient work environments, including the integrated document solution 'MPS Solution' to reduce document management costs, the 'Watchdog Solution' to strengthen paper and electronic document security, and 'Secufence,' which focuses on information leak prevention.
In January 2026, the company launched a subscription-based office solution platform called 'Sindorang,' introducing a flat monthly-fee model with a fixed-rate plan that removes billing volatility, allowing customers to pay a set monthly amount regardless of usage within an annual cap (20,000 color and 30,000 monochrome pages for the base plan).
In the past, Sindoh built a 3D printer business as a growth driver through an exclusive distribution agreement with US-based 3D Systems and a partnership with Belgium's Materialise, but a March 2025 report stated that the company had withdrawn from the 3D printer business it had previously pursued as a new growth initiative.
The competitive landscape is one in which Japanese makers such as Ricoh, Konica Minolta, and Kyocera hold a majority share of the MFP market, a field that concentrates advanced optical, chemical, mechanical, and communications technologies.
Sindoh also holds substantial non-operating assets, including real estate in Seongsu-dong, Seoul, and equity stakes in affiliated companies.
