A method of fabricating devices incorporating microelectromechanical systems (MEMS) using a UV curable tape includes providing a substrate (14) with a MEMS layer (18) arranged on one side (12) of the substrate (14). A further layer (10) is applied to the side (12) of the substrate (14). At least one operation is performed on the substrate (14) from a side (22) of the substrate (14) opposed to the side (12) having the MEMS layer (18). A holding tape (38) is applied to the side (22) of the substrate. At least one operation is then performed on the further layer (10) to define individual chips (20). Each chip (20) is composed of a part of the substrate (24), at least one part of the MEMS layer (18) and a part of the further layer (10). Individual chips (20) are then able to be released from the tape (38) by exposing the tape (38) to UV light.

A capping mechanism for a print engine includes a capping member (592) mountable in alignment with a printhead of the print engine. The capping member is displaceable into and out of abutment with the printhead for capping and uncapping the printhead respectively. A torsion bar (728) arrangement acts on the capping member for displacing the capping member. A mechanical displaceable element (570) co-operates with the torsion bar arrangement such that, when the element is in a parked position, the element engages the torsion bar arrangement to cause the capping member to be displaced into abutment with the printhead to cap the printhead. When the displaceable element is out of its parked position, the capping member is urged by leaf spring (734) by the torsion bar arrangement out of abutment with the printhead. Element (570) also moves a cutting device (566) for separating the printed sheet after printing.

Provided is an optical imaging pen configured to detect information encoded on a page with ink which is substantially invisible to the human eye. The pen includes a housing and an ink pen cartridge and a stylus mounted side by side within the housing, the ink cartridge and stylus configured to be brought forward through an open end of the housing by rotation of a pen top rotatably mounted on an end of the housing. The pen includes an electronics chassis mounted inside the housing, said chassis supporting an infrared LED for providing infrared radiation for projection onto the page, an image sensor for receiving reflected radiation from the surface, a radio frequency circuit having a radio frequency (RF) transmitter and receiver, and a controller circuit for controlling operation of the LED, sensor and radio frequency circuit. Also included is a rechargeable battery mounted about, and in contact with, the electronics chassis with an induction coil mounted about the chassis to enable induction recharging of the battery.

A printing method identifies where parts of an image will not be printed due to device failure and if possible shifts ink dots sideways or lengthways to adjacent rows or columns so as to lessen the visual effect of failure to print at the original location.

Methods and systems are disclosed which relate to online banking via interface surfaces printed with information and coded data. The coded data, encoded visibly or invisibly, may be queried by an appropriate sensing device. The sensing device communicates with a computer system. Together, the interface surfaces, sensing device and computer system are capable of effecting banking transactions over a network.

A component for a printhead module (12) includes a printhead chip (18) and a flexible printed circuit board (PCB, 54) on which the chip (18) is mounted. A carrier having fluid communication channels (72) defined therein supplies ink to the chip (18). The PCB (54) is bonded to the carrier in a liquid tight manner so that the PCB (54) forms a wall of an ink supply chamber (30) of the printhead module (12).

This invention concerns a consumable authentication protocol for validating the existence of an untrusted authentication chip, as well as ensuring that the authentication chip lasts only as long as the consumable. In a further aspect it concerns a consumable authentication system for the protocol. A trusted authentication chip has a test function; and the untrusted authentication chip has a read function to test data from the trusted chip, including a random number and its signature, encrypted using a first key, by comparing the decrypted signature with a signature calculated from the decrypted random number. In the event that the two signatures match, it returns a data message and an encrypted version of the data message in combination with the random number, encrypted using the second key. The test function operates to encrypt the random number together with the data message using a second secret key, compare the two versions of the random number encrypted together with the data message using the second key. In the event that the two versions match, the untrusted authentication chip and the data message are considered to be valid; otherwise, they are considered to be invalid.

The invention concerns a system and method enabling the copying of documents. It has specific application to the archiving and retrieval, and the scanning and reproduction, of documents which are or which may be capable of interacting with a computer system or network. Such a document has coded data printed on it allowing it to interact with the computer system or network by use of a sensing device operated by a user. Specifically, the method involves scanning a document which may contain both document information and coded data indicative of an identity of the document, forming a digital image of the document, and detecting, if the document contains said coded data indicative of the identity of the document, the coded data. If the document does contain such coded data, stored data representing the content of the document is accessed, and, depending on the operating instructions, either a copy of the document is printed, together with coded data indicative of an identity of the copy being printed on the copy, or data representing a copy of the document is stored, the stored data including a unique identifier for said copy. The invention can be employed for the printing of documents, the archiving and retrieval of documents, and the scanning and reproduction of documents. In copying documents, it can be used to produce pages of far higher quality than those produced by conventional photocopying means, often irrespective of the physical quality of the page to be copied.

The present invention provides a system for providing printed information to a user that is obtained from a data base of a first party, the system including: a user printer module for interfacing the user with the data base, the module being responsive to the user requesting first information from the data base for obtaining the first information and generating a first printed media that displays to the user the first information together with second information; identifier means for applying an identifier to the first printed media such that designation of the second information by the user corresponds to a designation of the identifier and results in the generation of a second printed media that displays to the user third information; and account means for applying a financial debit from the first party against a second party from whom the third information is derived.
