摘要： A coating apparatus for applying a coating liquid to a printing substrate. The apparatus includes a rotatable first roll, and a rotatable second roll positioned adjacent to the first roll and defining with the first roll a first nip through which the printing substrate passes. The apparatus also has a metering device for applying a layer of coating liquid onto the second roll, which in turn transfers the coating liquid to the printing substrate. The apparatus further has a controller that communicates with at least the second roll, wherein the controller performs the steps of determining whether the idle time of the second roll is longer than a predetermined threshold, setting a pre-spin flag if the idle time of the second roll is longer than a predetermined threshold, and directing the second roll to perform a pre-spin upon the presence of the pre-spin flag.

摘要： A method of improving a sealing between a purge mechanism and a printhead includes the steps of providing a purge cap with a perimetrical sealing lip; and exercising the perimetrical sealing lip of the purge cap against the sealing surface of the printhead. The exercising is effected by generating a repetitive relative movement between the sealing surface of the printhead and the perimetrical sealing lip of the purge cap.

摘要： A method of positioning an ink jet printhead in a printer includes dividing a bitmap into a plurality of rows of tiles. A subset of the rows of tiles to be printed in a next pass of the printhead is identified. Printable ones of the tiles in the subset of rows are identified. The printable tiles contain printable data. Within each printable tile, a top most location of the printable data and at least one of a left most location of the printable data and a right most location of the printable data are identified. A print medium is advanced in a feed direction until a portion of the print medium corresponding with the top most location of the printable data of at least one printable tile is substantially aligned with a top nozzle of the printhead. The printhead is moved, in a scan direction, directly to a position on the print medium corresponding to one of the left most location of the printable data of at least one printable tile and the right most location of the printable data of at least one printable tile.

摘要： An improved control method is provided that combines conventional ON-OFF control and conventional phase-angle control to reduce the AC inrush current to an electrical load, such as a tungsten halogen lamp used as a heating element in a laser printer, so that the power control circuit can satisfy both the European flicker and European harmonic requirements. Phase-angle control is applied to the load for a very short time period when it is initially energized, then the control circuit quickly switches from phase-angle control to standard ON-OFF control to reduce the harmonics generated by conventional phase-angle control methodologies. The electrical load exhibits three possible states: power full OFF, power ramp-up, and power full ON. During the power ramp-up state, power supplied to the load is adjusted by delaying the phase angle of the firing pulse relative to the start of each AC half cycle. Depending upon whether or not the system demand has been satisfied, the load's state can be changed from either power ramp-up to power full ON, or from power ramp-up to power full OFF. The phase-angle control methodology used during the power ramp-up state must be of sufficient time duration to reduce the amount of flicker to pass the European flicker test. However, this power ramp-up time interval must also be as short as possible to keep the harmonics as small as possible to the load, without the requirement of adding a large AC current harmonic attenuation inductor, which would otherwise be needed to pass the European harmonic test.
