Abstract: A heating element adjusts the curvature of a cylindrical wobble correction mirror to compensate and correct the scan line bow for an optical scanner. A current applied through the heating element along one side of the mirror will cause the mirror to bend vertically for a horizontal beam to adjust the scan line bow for a single beam and approximately equalize the scan line bow for multiple beams.

Abstract: A laser driver uses a switch, a current mirror, a control transistor and two current generators to control the ON and bias currents in a laser diode. In the bias mode the current from one generator is shared by one half of the current mirror and the adjustable control transistor. The other current generator then drives the other half of the mirror circuit and the laser diode in parallel, resulting in the laser diode getting the same amount of current that the control transistor gets. In the ON mode, the switch cuts off the first half of the current mirror, which is mirrored in the other half, so that all of the other generator current is used in the laser diode. The current drivers are adjustable to the ON current and the control transistor current is adjustable to the bias current.

Abstract: A managment station responds to an HTTP request for device discovery by spawning a device discovery task that creates a linked list and first broadcasts UDP based requests out on a subnetwork for devices on the same subnetwork to respond. Device information from responding network devices is stored in a linked list. This process is repeated until a specified length of time has expired. Then a second broadcast request is sent out that includes a list of printers that have responded so that they will nor keep responding. The list is updated by responses until there are no more responses. Any nodes in the linked list that still only have a network address are upadated by sending a unicast SNMP request those network addresses in order to get the additional information. The data from the linked list is sent back to the HTTP client.

Abstract: An ink jet printer that includes a printhead for ejecting ink droplets, an ink container for supplying ink to the printhead, and an ink level sensor for measuring the level of ink in the ink container, includes an ink level sensor activator. The ink level sensor activator causes the ink level sensor to measure the level of ink in the ink container after the printhead has ejected a predetermined quantity of ink. The ink level sensor activator records the quantity of ink ejected by the printhead onto the print medium by measuring to the number of droplets of ink ejected, and/or by determining the number of pixels in an image to be printed for which ink is to be ejected. If the quantity of ink ejected has a predetermined threshold, the ink level sensor measures the quantity of ink in the ink container.

Abstract: An active controller is provided to control operation of an acoustic printhead in which impedance of the printhead changes with both the active printing row and the distribution of active ejectors in the row. The active controller varies the input power to the printhead in response to active ejectors. Power requirements are insured while also reducing power consumption and maintaining print quality. The determination of RF power is based on the active row, how many ink ejectors are to be switched on, and their position within a row. Look-up tables used to determine proper attenuation or power values are provided in a cascaded fashion.
