A device for transferring images from an image donating member to an image receiving medium comprises a substrate, at least two electrodes disposed on the substrate, and at least one layer of coating disposed on the substrate having an outer surface for forming a nip region with the image donating member. The at least two electrodes are controllable to produce an electric field and control a position thereof at the nip region to allow transfer of an image from the image donating member to the image receiving medium in an image transfer operation.

Transfer device and system for an electrophotographic device comprising multiple electrodes

A regulator adapted to regulate the throughput of an ink between an ink source and a print head includes: (a) a pressurized chamber including an ink inlet in fluid communication with and ink source, an ink outlet in fluid communication with a print head, and at least one flexible wall; and (b) a lever including a flexible arm extending along a portion of the flexible wall and an opposing arm operatively coupled to a seal biased to close the ink inlet when the lever is in a first position and to open the ink inlet to allow fluid communication between the ink inlet and the pressurized chamber when the lever is pivoted to a second position; where a lower pressure differential across the flexible wall causes the flexible wall to actuate the flexible arm, pivoting the lever to the first position (inlet closed), where a higher pressure differential across the flexible wall causes the flexible wall to actuate the flexible arm to pivot the lever to the second position (inlet open), and where a pressure change from the lower pressure differential to the higher pressure differential across the flexible wall causes the flexible wall to actuate and flex the flexible arm without causing the lever to pivot.

Ink source regulator for an inkjet printer

The invention provides an improved ink jet cartridge for an ink jet printer and a method for making the improved ink jet cartridge. The method includes providing a thermoplastic, flexible web having an edge portion, a first side and a second side and providing a substantially inflexible frame member having at least one peripheral edge. Disposing the first side of the flexible web adjacent the peripheral edge of the frame, thereby defining a substantially closed cavity. Heat welding the edge portion of the web and peripheral edge of the frame to one another using a heated platen using a heat welding structure and conditions which minimize thinning of the flexible web on the bonding surface at least adjacent the substantially closed cavity. Minimizing the thinning of the flexible web adjacent the closed cavity substantially improves the weld and resulting reliability of the ink cartridge.

Ink jet printer ink cartridge manufacturing method

A fluid pressure transducer assembly (,) includes an exemplary silicon or ceramic capacitive transducer (,) having a relatively flexible diaphragm portion (,) mounted on a ceramic substrate or circuit board (,) over a bore (,) so that the diaphragm is exposed to fluid pressure from a port (,) received through the bore. The circuit board is received in a plastic housing (,) laterally positioned by guides (,) on three height control pins (,) to vertically position the circuit board a defined, precise distance above a platform (,) on which a bead of adhesive sealing material has previously been placed, the sealing material having a height greater than the distance between a plane in which the free end of the height control pins lie and a plane in which the top surface of the platform lies. As a result, the circuit board is sealed to the plastic housing through a bead having a uniform, precise height all around its circumference to isolate temperature expansion stresses. According to another feature of the invention an electrically conductive layer (,) is formed on the top surface of the circuit board beneath the transducer (,) and another electrically conductive layer (,) is formed on the top surface of the transducer (,) electrically joined together to form an EMI shield.
