More individuals began using page printers, fax machines, copiers, and image scanners at the start of the 1990s because of increasingly affordable prices. Oki Electric developed the DOC-IT 3000 and the DOC-IT 4000 for the European and North American markets as an effort to integrate the document processing of scanned images — including sending faxes, making copies, or storing data — for much more efficient work patterns. The two models were the same, apart from their print resolutions: 300 dpi and 400 dpi.
