  • Patent number: 10195857
    Abstract: A jet recovery print process is performed each time before printing a print job, when an inactivity period of non-printing has been exceeded, or during a long print job, where the jets might clog with debris. The jet recovery print process ejects the ink from the inkjets by printing (using the inkjets) a sacrificial page in a jet recovery pattern, while operating the actuators in the inkjets at their maximum voltage rating. The jet recovery pattern is designed to purge all the ink from all the inkjets. Thus, in the jet recovery print process, the controller operates the actuators at their maximum voltage rating so as to provide a higher driving force for the ink to be ejected from the inkjets and thereby make the purge process more effective.

  • Patent number: 9751304
    Abstract: A printer that prints printouts processed in a post-printing process such as a label application step reduces the difference between the target time for printing completion and the actual completion of printing. When a print command is acquire-d from a control device 2, the printer 10 calculates a required printing time Tp including a time T1 required for the print preparation operation, and acquires a target time Tt for completing the specified printing. The controller 12 supplies a trigger signal for starting printing to the print unit 11 at a time calculated back from the target time Tt. The controller 12 calculates the required printing time Tp by adding the time required for the print preparation operation according to the current status of the printer 10 to the time required for the printing operation itself.

The inkjet printer 1 has first and second inkjet heads 13A and 13B mounted on a head carriage 14. Before printing starts, the inkjet printer moves the head carriage 14 from a home position HP to a shift position SP so that the second inkjet head 13B, which is closest to the home position HP, is opposite a maintenance head cap 22 with an ink absorption capability and cleans the inkjet head. The head carriage 14 is then returned to the home position HP so that the first inkjet head 13A is opposite the maintenance head cap 22 and cleans the inkjet head. The head carriage 14 then moves to the printing area C side and printing starts.

  • Patent number: 9381761
    Abstract: An inkjet printer includes a determination unit, a maintenance setting value decision unit, and a controller. The determination unit determines whether or not an ink cartridge has passed the recommended time limit, based on the manufacturing date or the start-of-use date, the normal consumption period of the ink cartridge, and the elapsed period from the manufacturing date or the start-of-use date of the ink cartridge. The maintenance setting value decision unit reads the cycle and the strength of a maintenance operation for each type of ink from the memory, in a case where the determination unit determines that the recommended time limit has passed, and selects and decides the shortest cycle and the strongest strength, as maintenance setting values. The controller causes a pressure regulator and a pressure regulating drive unit to execute a purge operation, based on the determined maintenance setting values.

  • Patent number: 9340012
    Abstract: An image forming apparatus includes: a liquid ejecting head including a nozzle that ejects a droplet and a pressure producing unit that produces pressure to pressurize a pressure chamber communicating with the nozzle; and a head drive controlling unit that provides a driving signal to the pressure producing unit. The head drive controlling unit outputs the driving signal including at least a first driving pulse and a second driving pulse to eject droplets and a residual vibration suppressing pulse to suppress residual vibration in the pressure chamber without ejecting a droplet. The residual vibration suppressing pulse is output at such a timing that the residual vibration suppressing pulse has an opposite phase to a composite vibration Vab that is formed by superposition of a meniscus vibration Va generated by droplet ejection with the first driving pulse and a meniscus vibration Vb generated by droplet ejection with the second driving pulse.

  • Patent number: 9126437
    Abstract: In the case where a preliminary discharge operation is always performed at a position that is spaced apart from a recording area, the time taken for a recording head to be moved to a preliminary discharge position is increased, and this results in a decrease in throughput. In the case where it is determined that a leading end or a trailing end of a recording medium is located on a platen, positions at which the distance from an end of a recording medium to a recording head with respect to a moving direction is not smaller than a threshold are determined as preliminary discharge positions, and the recording head is controlled to perform a preliminary discharge operation.
