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. The toner is transferred to paper via an electrostatically charged drum unit, and fused onto the paper by heated rollers during the printing process. It will not stain like ink cartridges, but it can get messy if handled improperly. Variants Low-end to mid-range laser printers typically contain two consumable parts: the toner cartridge itself (which has a typical life of 2,000 pages) and the drum unit (a typical life of 40,000 pages). Some toner cartridges incorporate the drum unit in the design, and both drum and cartridge are replaced simultaneously; cost of a cartridge is higher than a toner-only cartridge, although separate drum replacement is avoided. Toner cartridges have the same function as ink cartridges used by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chip (computing)
An integrated circuit (IC), also known as a microchip or simply chip, is a set of electronic circuits, consisting of various electronic components (such as transistors, resistors, and capacitors) and their interconnections. These components are etched onto a small, flat piece ("chip") of semiconductor material, usually silicon. Integrated circuits are used in a wide range of electronic devices, including computers, smartphones, and televisions, to perform various functions such as processing and storing information. They have greatly impacted the field of electronics by enabling device miniaturization and enhanced functionality. Integrated circuits are orders of magnitude smaller, faster, and less expensive than those constructed of discrete components, allowing a large transistor count. The IC's mass production capability, reliability, and building-block approach to integrated circuit design have ensured the rapid adoption of standardized ICs in place of designs using discre ...

Office Equipment
Office supplies are consumables and equipment regularly used in offices by businesses and other organizations, required to sustain office operations. For example, office supplies may be used by individuals engaged in written communications, record-keeping and bookkeeping. The range of items classified as office supplies varies, and typically includes small, expendable, daily use items, and consumable products. Typical products Office supplies are typically divided by type of product and general use. Some of the many different office supply products include *Blank sheet paper: various sizes from small notes to letter and poster-size; various thicknesses from tissue paper to 120 pound; construction paper; photocopier and inkjet printer paper; *Preprinted forms: time cards, tax reporting forms (1099, W-2), "while you were out" pads, desk and wall calendars; *Label and adhesive paper: name tags, file folder labels, post-it notes, and address labels; *Media: Ink cartridge, ink an ...

Laser Printers
Laser printing is an electrostatic digital printing process. It produces high-quality text and graphics (and moderate-quality photographs) by repeatedly passing a laser beam back and forth over a negatively charged cylinder called a "drum" to define a differentially charged image. The drum then selectively collects electrically charged powdered ink ( toner), and transfers the image to paper, which is then heated to permanently fuse the text, imagery, or both to the paper. As with digital photocopiers, laser printers employ a xerographic printing process. Laser printing differs from traditional xerography as implemented in analog photocopiers in that in the latter, the image is formed by reflecting light off an existing document onto the exposed drum. The laser printer was invented at Xerox PARC in the 1970s. Laser printers were introduced for the office and then home markets in subsequent years by IBM, Canon, Xerox, Apple, Hewlett-Packard and many others. Over the decades, qua ...

Pull Printing
Pull printing is a printing feature where a user's print job is held on a server (server-based pull printing) or on a user's workstation (serverless pull printing) and released by the user at any printing device ( pulled to the printer) which supports this feature. A number of software products exist that support pull printing. The user needs to first authenticate themselves at the printer, either using embedded software (e.g. i.c.w. a pincode), or an external device (e.g. i.c.w. a smartcard). Once they have been authenticated, the user may select from the list of print jobs from the server, web portal or directly from the client PC which ones they wish to release at the current device. Some systems also allow delegation where the user may access print jobs submitted by other users or systems. Advantages * Flexibility: The user can print first and choose the printer afterwards (while standing next to it). * IT management: instead of having to manage hundreds of print queues on pri ...

Toner Refill
Toner refilling is the practice of refilling empty laser printer toner cartridges with new toner powder. This enables the cartridge to be reused, saving the cost of a complete new cartridge and the impact of the waste and disposal of the old one. While toner cartridges are commonly refilled with results reported to be good, in at least some cases refilling without full remanufacturing may leave waste toner from each print and paper debris in the cartridge, potentially causing backgrounding problems and producing contamination in the refilled cartridge. The U.S. patent for the "Refillable toner cartridge" was issued to Fred Keen on March 28, 1989. Refilling methods There are several different methods for refilling cartridges: Toner cartridges cannot be refilled indefinitely, because mechanical parts such as rollers wear out. Some cartridges include the electro-optical drum, which becomes depleted and can be scratched. Organizations refilling cartridges for resale usually cl ...

Compatible Ink
Compatible ink (or compatible toner) is manufactured by third-party manufacturers and is designed to work in designated printers without infringing on patents of printer manufacturers. Compatible inks and toners may come in a variety of packaging including sealed plastic wraps or taped plastic wraps. Regardless of packaging, compatible products are generally priced lower than original equipment manufacturer (OEM) brand inks and toners. While there has been considerable debate and litigation involving the ink and toner patents of printer manufacturers, third-party manufacturers continue to thrive. Manufacturers of compatible ink and toner products currently control about 25% the ink and toner market well over $8 Billion annually. Types Compatible ink is manufactured for several types of machines including fax machines, laser printers, inkjet printers, multifunction printers, and copiers. Aside from compatible products, three other sources of consumables are also available to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ink Cartridge
An ink cartridge or inkjet cartridge is a component of an inkjet printer that contains ink to be deposited onto paper during printing. It consists of one or more ink reservoirs and can include Inkjet printer#Underlying business model, electronic contacts and a chip to exchange information with the printer. Design Thermal Most consumer inkjet printers use a Thermal expansion, thermal inkjet. Inside each partition of the ink reservoir is a heating element with a tiny metal plate or Resistor ladder, resistor. In response to a signal given by the printer, a tiny current (electricity), current flows through the metal or resistor, making it warm, and the ink in contact with the heated resistor is vaporized into a tiny steam bubble inside the nozzle. As a result, an ink droplet is forced out of the cartridge nozzle onto the paper. This process takes a fraction of a millisecond. The printing depends on the smooth flow of ink, which can be hindered if the ink begins to dry at the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Recycling
Recycling is the process of converting waste materials into new materials and objects. This concept often includes the recovery of energy from waste materials. The recyclability of a material depends on its ability to reacquire the properties it had in its original state. It is an alternative to "conventional" waste disposal that can save material and help lower greenhouse gas emissions. It can also prevent the waste of potentially useful materials and reduce the consumption of fresh raw materials, reducing energy use, air pollution (from incineration) and water pollution (from landfilling). Recycling is a key component of modern waste reduction and represents the third step in the "Reduce, Reuse, and Recycle" waste hierarchy, contributing to environmental sustainability and resource conservation. It promotes environmental sustainability by removing raw material input and redirecting waste output in the economic system. There are some ISO standards related to recycling, su ...

Remanufacturing
Remanufacturing is "the rebuilding of a product to specifications of the original manufactured product using a combination of reused, repaired and new parts". It requires the repair or replacement of worn out or obsolete components and modules. Parts subject to degradation affecting the performance or the expected life of the whole are replaced. Remanufacturing is a form of a product recovery process that differs from other recovery processes in its completeness: a remanufactured machine should match the same customer expectation as new machines. In 1995, the United States Environmental Protection Agency (EPA) implemented the Comprehensive Procurement Guideline (CPG) program to promote waste reduction and resource conservation through the use of materials recovered from solid waste, and to ensure that the materials collected in recycling programs will be used again in the manufacture of new products. The EPA is required to designate products that are or can be made with recovered ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Inkjet Printing
Inkjet printing is a type of computer printing that recreates a digital image by propelling droplets of ink onto paper or plastic substrates. Inkjet printers were the most commonly used type of printer in 2008, and range from small inexpensive consumer models to expensive professional machines. By 2019, laser printers outsold inkjet printers by nearly a 2:1 ratio, 9.6% vs 5.1% of all computer peripherals. The concept of inkjet printing originated in the 20th century, and the technology was first extensively developed in the early 1950s. While working at Canon in Japan, Ichiro Endo suggested the idea for a "bubble jet" printer, while around the same time Jon Vaught at Hewlett-Packard (HP) was developing a similar idea. In the late 1970s, inkjet printers that could reproduce digital images generated by computers were developed, mainly by Epson, HP and Canon. In the worldwide consumer market, four manufacturers account for the majority of inkjet printer sales: Canon, HP, Ep ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
