摘要： A printing device includes a print media advancement subsystem for providing accurate and timely print media advancement in the printing device. The print media advancement subsystem includes a vacuum chamber for generating a vacuum force through a platen for holding a print media stationary. In response to receiving a print media advance signal from a controller in the printing device, a sealing plate forming a side of the vacuum chamber is removed from the vacuum chamber. When the sealing plate is removed, the vacuum chamber is substantially open to the atmosphere, causing the vacuum chamber to pressurize. The pressurization of the vacuum chamber results in removal of the vacuum force from the print media, allowing the print media to advance along the top surface of the platen with minimal friction.

摘要： A misalignment compensation technique for a dot printer is disclosed. This technique first supplies printing instructions to a printhead for energizing printing elements in various groups (primitives) to print a pattern on a medium. The printed pattern is then detected by optical sensors in the printer. Based on the detection, a position offset error for each primitive is determined. These errors are used to generate a separate time correction for each of the primitives such that, when the printer is used normally, the time period for printing a dot will be advanced or delayed for each primitive so as to align the dots printed by the primitives. In another embodiment, alignment data taken by a manufacturing line sensor is stored in a memory on the print cartridge. After the print cartridge is installed in the printer, a second optical test completes the data needed to create timing correction values.

摘要： A carriage-mounted optical sensor for an ink-jet hard copy apparatus includes a unitary light tube member which holds the optical components in fixed positions relative to each other as well as relative to an outer protective casing which attaches to the carriage. The light tube member serves as a cap to capture two LEDs between itself and a protective casing, to capture an optical lens between itself and a photocell holder, and to directly engage the casing. An inner wall having light redirecting features provides an improved light path cylinder and the device obtains a more accurate representation of the test pattern mark shape, reflectance value, and position.

摘要： A wet ink printer uses a heated printhead. A platen guides and supports the print medium during printing, and has a plurality of raised ribs. In an example, the ribs extend on the base generally along the advance direction of the print media. Each rib comprises a discontinuous series of rib portions, and wherein between each adjacent pair of ribs is provided a spacing to allow deformation of the print medium towards the platen base.

摘要： In various methods, image registration variations among test patterns are used to calibrate misalignment among one or more printheads, paper advance distance, different portions of an inkjet printhead, or bidirectional printhead alignment. A set of test patterns are printed. Each pattern includes a reference portion and a varying portion. The varying portion is changed from pattern to pattern in a manner for testing a parameter being calibrated. An optical sensor scans each test pattern. The parameter setting for the lest pattern having the highest reflectance (i.e., most blank space) is selected as the calibrated parameter value.
