Liquid ejecting apparatus and control method

A liquid ejecting apparatus includes: a liquid ejecting head that includes nozzle openings through which liquid is ejected and pressure generation units that cause changes in pressure of the liquid inside pressure generation chambers communicating with the nozzle openings; a control unit that supplies a driving signal for causing the liquid ejecting head to eject the liquid, to the pressure generation units, and controls ejection of the liquid by the liquid ejecting head; and a temperature detection unit that detects a temperature of a contact portion with which the liquid ejected by the liquid ejecting head comes in contact, wherein the control unit corrects the driving signal on the basis of the temperature information detected by the temperature detection unit.

Sheet stacking apparatus and image forming apparatus

A sheet stacking apparatus includes a gripper configured to discharge a sheet, a plurality of stacker trays arranged in a row and configured to stack the discharged sheet, and a guiding unit configured to guide the discharged sheet to a predetermined position. The plurality of stacking trays are horizontally arranged so that a large number of sheets can be stacked without increasing the size of the sheet stacking apparatus.

Medium detection device and image formation apparatus

A medium detection device includes: a sensor lever configured to rotate corresponding to a travel of a recording medium; a sensor configured to detect the rotation of the sensor lever; a stopper having a guide surface inclined with respect to the movement direction of the sensor lever and configured to stop movement of the sensor lever upon the rotation of the sensor.

Drop Mass Calibration Method Based on Drop Positional Feedback

A method compensates for changes in drop mass of drops ejected by ink jets in a printhead of an ink jet imaging device. The method comprises identifying an average drop placement position for a printhead with reference to ink drop positions on an image receiving member and adjusting a parameter of one or more ink jet driving signals in response to the average drop placement position being greater than a predetermined threshold.

Image formation device

An image formation device is configured such that a length of a sheet feed path from a sheet accommodation unit to a sheet detection unit is greater than the sheet distance for a predetermined type sheet that has substantially the same sheet length as a maximum size sheet employable in the image formation unit. A sheet length of the sheet fed by the sheet feed mechanism is measured. If the sheet length of a firstly fed sheet, which is fed in response to an image formation instruction and measured by the measuring unit, is equal to the sheet length of the predetermined type of sheet, the control unit feeds a subsequent sheet with the sheet distance corresponding for the maximum size sheet between a trailing end of the previously fed sheet and the leading end of the subsequent sheet.

Liquid ejecting device

A liquid ejecting device is provided. The liquid ejecting device includes a conveyer, liquid ejecting heads with nozzles to eject droplets of liquid, an liquid purging unit to purge the liquid out of the nozzles, a detector unit to detect presence of a recording medium, a storage unit to store length of the recording medium, a judging unit to judge whether the recording medium is jammed in a conveyer path, a head identifier unit to identify an overlapping liquid ejecting head assumedly facing the jammed recording medium based on the detected result obtained by the detector unit and the length of the recording medium, and an purge controller unit to control an amount of the liquid to be ejected from the nozzles in the remaining liquid ejecting heads to be smaller than an amount of the liquid to be ejected from the nozzles in the identified overlapping liquid ejecting head.

Issue detection in a digital printer

Detecting an issue in a digital printer that has an optical element positioned to direct a laser beam towards a photoconductor surface may include sending optical element position commands to move the optical element to compensate for inconsistent movements of a photoconductor drum and creating a record of the optical element position commands.

MARK, METHOD AND SYSTEM FOR COLOR QUALITY PARAMETERS MEASUREMENT

A mark, a method and a system for colour quality parameters measurement of a printing press. The mark comprises a plurality of spots, wherein each spot comprises encoded dot level information, the distribution of spots defines a signature pattern for each process colour, a plurality of said spots is associated to each ink key of the printing press along an area of interest and the mark is invisible to the naked eye. The colour quality parameters measurement system comprises image capturing means synchronizable with the printing press and capable of accessing the entire width of an area of interest of the printing press, processing means, user control interface for communication between the processing means and the press user and a mark according to the invention. The method for colour quality parameters measurement comprises the steps of printing a mark according to the invention on an area of interest of a printing job, capturing an image of the printed mark, identifying process colour in the mark and determining at least one colour quality parameter. 116.-. (canceled)17. A mark for colour quality parameters measurement of a printing press that includes a plurality of ink keys , the mark comprising a plurality of spots , wherein at least some spots of said plurality of spots are associated to particular ink keys of said plurality of ink keys of the printing press along an area of interest ,characterized in that:the plurality of spots comprises encoded dot level information;a distribution of the plurality of spots defines a signature pattern for each process colour of a plurality of process colours;the mark is invisible to a naked eye of a human observer; andthe encoded dot level information comprises solid densities and/or partial densities for the plurality of process colours.18. A mark for colour quality parameters measurement according to claim 17 , wherein the encoded dot level information comprises solid densities of substantially 100% and partial densities of ...
