This standard is used to prescribe the test method that manufacturers and test labs use to determine ink jet cartridge yields. It also standardizes the appropriate method of describing the yield of cartridges in documentation supplied to the consumer by the manufacturer.
Duplicating machines were the predecessors of modern document-reproduction technology. They have now been replaced by digital duplicators, scanners, laser printers, and photocopiers, but for many years they were the primary means of reproducing documents for limited-run distribution.
Unlike spirit duplicators (where the only ink available is depleted from the master image), mimeograph technology works by forcing a replenishable supply of ink through the stencil master. In theory, the mimeography process could be continued indefinitely, especially if a durable stencil master were used (e.g. a thin metal foil).
Digital duplicators can provide a reliable and cost efficient alternative to toner-based copiers or offset printing equipment. [1] The digital duplicator begins by digitally scanning the original and then transferring it to a master template through a thermal imaging process. Then the master is automatically wrapped around a print cylinder ...
A Hewlett-Packard laser toner cartridge. A toner cartridge, also called laser toner, is the consumable component of a laser printer.Toner cartridges contain toner powder, a fine, dry mixture of plastic particles, carbon, and black or other coloring agents that make the actual image on the paper.
Risograph is a brand of digital duplicators manufactured by the Riso Kagaku Corporation, [1] [2] that are designed mainly for high-volume photocopying and printing. It was released in Japan in 1980. It is sometimes called a printer-duplicator, as newer models can be used as a network printer as well as a stand-alone duplicator.
Epson's EcoTank printers offer a refillable ink tank system, which can potentially lower the cost per page compared to traditional ink cartridges, with a higher cost-of-entry. [12] This operates similar to continuous ink system printers, including notifying the user's PC to ensure the tanks do not run dry, which can damage the print head.
Low-end copiers also use digital technology, but tend to consist of a standard PC scanner coupled to an inkjet or low-end laser printer, which are far slower than their counterparts in high-end copiers. However, low-end scanner-inkjets can provide color copying at a lower upfront purchase-price but a much higher cost per copy.
