During the 1980s, a convergence began in some high-end machines towards what came to be called a multi-function printer: a device that combined the roles of a photocopier, a fax machine, a scanner, and a computer network-connected printer. Low-end machines that can copy and print in color have increasingly dominated the home-office market as ...
The IBM 6670 Information Distributor (6670-001) was a combination laser printer and photocopier introduced by IBM. [1] Announced on February 14, 1979, as part of Office System/6, its feature set included two-sided printing. [2] The New York Times described it in 1979 as "A key component of the office of tomorrow."
The segments roughly divided the MFPs according to their speed in pages-per-minute (ppm) and duty-cycle/robustness. However, many manufacturers [ quantify ] are beginning to avoid the segment definition for their products, as speed and basic functionality alone do not always differentiate the many features that the devices include.
IBM Copier I. On April 21, 1970, IBM announced their first copier simply called the IBM Copier. Its IBM Machine type/Model is 6800–001. When the IBM Copier II was released, IBM renamed the IBM Copier to the IBM Copier I. [21] In terms of competition, while the Copier I was faster than the Xerox 914 (which ran at 7 copies per minute) [22] it was reported as competing with the desktop Xerox ...
Yellow dots on white paper, produced by color laser printer (enlarged, dot diameter about 0.1 mm) Printer tracking dots, also known as printer steganography, DocuColor tracking dots, yellow dots, secret dots, or a machine identification code (MIC), is a digital watermark which many color laser printers and photocopiers produce on every printed page that identifies the specific device that was ...
The modern version of a mimeograph, called a digital duplicator, or copyprinter, contains a scanner, a thermal head for stencil cutting, and a large roll of stencil material entirely inside the unit. The stencil material consists of a very thin polymer film laminated to a long-fiber non-woven tissue.
It was claimed that a roller copier could make a half dozen copies of a typewritten letter if the letter was run through the copier several times. It could make a dozen copies if the letter was written with a pen and good copying ink. The Process Letter Machine Co. of Muncie, Indiana, offered the New Rotary Copying Press, a loose-leaf copier ...
