摘要： A method for adjusting the tension of a continuous web of recording media in a printing system. The method includes identifying a tension in the continuous web and adjusting the tension in response to the amount of ink being deposited on the recording media. An offset tension value is determined, stored in memory, and used by a controller to adjust the velocity or tension of the continuous web moving through the printing system to improve the printing of images.

摘要： A pressurized ink delivery system having two delivery reservoirs in an inkjet printer enables a control system to alternate between the two reservoirs for printhead supply without coupling pressurized air from a delivery reservoir to a low pressure source of ink. Each delivery reservoir includes a conduit having an orifice that enables the pressure within a delivery reservoir to exit the reservoir before the ink delivery reservoir is fluidly connected to the low pressure source of ink for refilling of the delivery reservoir. By dropping the high pressure reservoir to atmosphere and then switching the seal actuators for the two reservoirs, the spray of ink is avoided.
摘要翻译：在喷墨打印机中具有两个输送储存器的加压油墨输送系统使得控制系统能够在两个储存器之间交替用于打印头供应，而不将加压空气从输送储存器耦合到低压油墨源。每个输送储存器包括具有孔口的管道，该孔口使得输送储存器内的压力能够在油墨输送储存器流体连接到低压油墨源之前离开储存器，以重新填充输送储存器。通过将高压储存器放置到大气中，然后切换两个储存器的密封致动器，避免了喷墨。

摘要： A maintenance system and method for maintaining an imaging member of an imaging device includes a pre-cleaning device to clean the imaging member; an applicator to apply release agent to the imaging member; a metering device to meter release agent on the imaging member; a reservoir to remotely store release agent; and a pump to supply the applicator with release agent from the reservoir. The saturation level of the applicator is monitored and maintained within a predetermined range. The applicator, pre-cleaning device and metering device may be independently actuated to engage the imaging member. Release agent collected by the pre-cleaning device and/or metering device may be recycled. Debris collected by the pre-cleaning device and/or metering device may be stored and/or removed.
