Reverse automatic document feeder A scanner with a duplexing automatic document feeder A Konica Minolta photocopier with an automatic document feeder in use. In multifunction or all-in-one printers, fax machines, photocopiers and scanners, an automatic document feeder or ADF is a feature which takes several pages and feeds the paper one page at a time into a scanner or copier, [1] allowing the ...
ImageWriter LQ (Letter Quality) is a 27-pin dot matrix printer introduced in 1987 by Apple Computer, Inc. The print quality was comparable to competing 24-pin dot-matrix printers, and offered graphics at 320 × 216 DPI. Guaranteed compatibility with both Apple II and Mac computers made it popular in schools. [citation needed]
Online sensors are set on the scanner beam to scan across the web. Typical crossing time of the web in new systems is 10–30 s (8m web, 60 cm/s). If the web speed is 1200 m/min and web width 8.5 m, the web moves 280 m during a scan, and the sensor moves the same distance diagonally across the web.
Nowadays, the most common use of spooling is printing: documents formatted for printing are stored in a queue at the speed of the computer, then retrieved and printed at the speed of the printer. Multiple processes can write documents to the spool without waiting, and can then perform other tasks, while the "spooler" process operates the ...
Fused filament fabrication uses material extrusion to print items, where a feedstock material is pushed through an extruder. In most fused filament fabrication 3D printing machines, the feedstock material comes in the form of a filament wound onto a spool. The 3D printer liquefier is the component predominantly used in this type of printing.
A HP color laser printer with its cartridge drawer open showing the four toner cartridges inside. Color laser printers use colored toner (dry ink), typically cyan, magenta, yellow, and black . While monochrome printers only use one laser scanner assembly, color printers often have two or more, often one for each of the four colors.
Many MFP types, regardless of the category they fall into, also come in a "printer only" variety, which is the same model without the scanner unit included. This can even occur with devices where the scanner unit physically appears highly integrated into the product. As of 2013, almost all printer manufacturers offer multifunction printers ...
There are several types of 3D printer extruders. A Bowden extruder is a type of extruder that pushes filament through a long and flexible PTFE (Teflon) tube to the hot end. [1] An alternative type of extruder which is also widely used in filament 3D printers is the direct-drive extruder, which sits closer to the extruder hot end.
