摘要:
A liquid toner having a mineral oil vehicle, a blend of Surlyn ionomeric resin and Nucrel resin, pigment and, as charge director, lecithin, N-methyl-2-pyrrolidone and calcium Petronate. The charge director optimizes speed of recovery of charge properties during continual use. The mineral oil does not vaporize well and is readily condensed, thus permitting use as a confined toner.

Trimers of C.sub.9 to C.sub.11 alpha olefins are useful as carrier fluid in liquid toner for electrophotography. Their use practically eliminates air pollution, oil slicks when liquid toned prints are placed on a surface and a halo effect.
摘要:
A liquid toner for electrostatic imaging having 65-90 percent by weight of solids of terpolymer of about in the weight ratio of about 60/33/7 of styrene, n-butyl acrylate and methacrylic acid, respectively; 10-30 percent by weight of solid of pigment, an ionic or zwitterionic charge director, 1-5 percent by weight aluminum tristearate, and the remainder mineral oil as a vehicle.
摘要:
Cleaning roller (7) contacts intermediate transfer roller (4), each rotating at the same surface speed to avoid rubbing. The cleaning roller has an electric potential sufficient to remove toner from the transfer roller to clean it. Silicone oil is applied by a roller 29, which is wetted by oil from a oil impregnated wiper (31). The oil facilitates cleaning and reduces wear of the intermediate transfer roller, which is typically soft to facilitate transfer.
摘要:
In imaging apparatus (1) a contact heater (9) applies heat and electrical bias to a toner image on an intermediate accumulator (5). The bias is of polarity to repel the toner. The toner image is coalesced such that additional heating may be reduced or eliminated at the transfer to paper (7) by pressure roller (11).
摘要:
A virtual printer interface node enables a non-cloud-ready printer to communicate with a cloud-based service, residing on an internet. The virtual printer interface node includes a housing; a communication interface to provide communication directly to the network router; and a microcontroller operatively connected to the communication interface. The microcontroller converts commands, received through the communication interface, from the cloud-based service, residing on the internet, to native protocols of the non-cloud-ready networked printer and communicates the converted native protocols to the non-cloud-ready networked printer.
摘要:
Document processing devices and methods are presented, in which the device stores a remaining print unit value in its memory that represents the amount of print units currently available to enable the device to perform the document processing operations, and a programmable computer of the device selectively performs document processing jobs for users and decrements the remaining print unit value until the value reaches zero and the device provides for expenditure of print units according to color content and/or coverage levels determined for a given job.

A system architecture and method are provided that allow a retailer to provide a unique shopping experience to their customers. The customers, who belong to multiple affinity groups and have a purchasing history, are provided coupons via a wireless mobile device at the time they enter a zone on or about a retail location. The customer may use their wireless mobile device to select coupons or incentives for items that they wish to purchase in the store and thereby receive a discount. Retailers and product manufacturers may incentivise customers to purchase their goods at or near the point of product selection.
摘要:
The invention described in the specification relates to an improved ink jet printer cartridge structure which includes a substrate carrier or nose piece upon which semiconductor devices for ink jet printheads are mounted. The substrate carrier has a top surface containing one or more substrate locator wells each well having well walls, a well base and at least one ink feed slot in each well base and side walls attached to the top surface along the perimeter thereof. One or more of the side walls contain fins for heat removal from the substrate carrier and at least two alignment devices attached adjacent at least one of the side walls for precisely aligning the substrate carrier in a printer carriage. Among the advantages of the substrate carrier is that it provides a suitable means for substrate alignment for multiple substrates, a means for cooling multiple substrates, a means for fixedly or removably attaching the carrier to a ink reservoir body and a means for accurately aligning the carrier and reservoir body in a carriage of a printer.
摘要:
A method for making an inkjet printhead nozzle plate from a composite strip containing a nozzle layer and an adhesive layer is disclosed. The adhesive layer is coated with a polymeric sacrificial layer prior to laser ablating the flow features in the composite strip. A method is also provided form improving adhesion between the adhesive layer and the sacrificial layer. Once the composite strip containing the sacrificial layer is prepared, the coated composite strip is then laser ablated to form flow features in the strip in order to form the nozzle plates. After forming the flow features, the sacrificial layer is removed individual inkjet printhead nozzle plate are separated from the composite strip by singulating the nozzle plates with a laser.
