    摘要： At the time of an initializing operation, it is determined that an indirect transfer film has not been replaced before power-on if transferred sensor marks are detected while the indirect transfer film is conveyed from a supply spool to a winding spool, the unused amount of the indirect transfer film is estimated based on the ratio between the rotation angle of the supply spool and the rotation angle of the winding spool, if the unused amount is estimated to be 2% that is a remaining amount alert threshold or more, positioning of the primary transfer is performed based on the last sensor mark among the sensor marks, and if the unused amount is estimated to be less than 2%, it is determined that the unused amount is greater than an amount necessary for recording on the next recording medium unless an end mark is detected while the indirect transfer film is conveyed by predetermined image areas from the last sensor mark.

    摘要： A method of operating a transfer printer configured to transfer ink from a printer ribbon to a substrate which is transported along a predetermined substrate path adjacent to the printer. The printer comprises a tape drive comprising two tape drive motors, two tape spool supports on which said spools of ribbon may be mounted, each spool being drivable by a respective one of said motors. The printer further comprises a printhead being displaceable towards and away from the predetermined substrate path and being arranged to, during printing, contact one side of the ribbon to press an opposite side of the ribbon into contact with a substrate on the predetermined substrate path, and a printing surface. The printer further comprises a controller configured to control the tape drive to transport ribbon between the first and second ribbon spools. The method comprises controlling the tape drive to perform a ribbon movement in which ribbon is transported between first and second ribbon spools along a ribbon path, the ribbon path having a first length during a first part of said ribbon movement, and a second length during a second part of said ribbon movement, a transition from the first length to the second length being caused by a displacement of the printhead with respect to the printing surface, wherein control of at least one of the tape drive motors is based upon data indicative of the first and second lengths.

    摘要： A thermal transfer printer comprising: first and second spool supports each being configured to support a spool of ribbon; a ribbon drive configured to cause movement of ribbon from the first spool support to the second spool support; a printhead configured to selectively transfer ink from the ribbon to a substrate; a motor configured to cause movement of the printhead towards and away from a printing surface against which printing is carried out, the motor shaft being coupled to the printhead by an inelastic coupling such that the elasticity provided by internal components of the motor is greater than the elasticity of the coupling between the printhead and the motor shaft; and a controller configured to provide a predetermined control signal to the motor to cause the motor to press the printhead against the printing surface.

    摘要： A thermal transfer printer comprising: first and second spool supports each being configured to support a spool of ribbon; a ribbon drive configured to cause movement of ribbon from the first spool support to the second spool support; a printhead configured to selectively transfer ink from the ribbon to a substrate, the printhead pressing the print ribbon and substrate together against a print roller; a substrate drive configured to cause movement of a substrate past the printhead; a sensor configured to monitor rotation of the print roller and generate a signal indicative thereof; and a controller configured to determine a measure of movement of the substrate and/or ribbon past the print roller based on the signal output by the sensor.
