A printer includes a head, an electrode, a moving unit, a voltage application circuit, and a controller. The head has an ejection surface having a nozzle. The head is configured to eject liquid from the nozzle. The moving unit is configured to move at least one of the electrode or the head. The voltage application circuit is configured to apply a certain voltage between the head and the electrode. The controller is configured to: drive the moving unit such that the ejection surface faces the electrode; drive the voltage application circuit to apply the certain voltage between the head and the electrode; compare a level of an output signal input to the controller from the electrode with a particular threshold; and based on the comparison result, determine that liquid is present between the ejection surface and the electrode.

A liquid ejecting apparatus includes a liquid ejecting head ejecting liquid onto a medium transported on a transport path extending in a depth direction, a carriage holding the liquid ejecting head and reciprocally moving in a width direction so as to cross the transport path, and a waste liquid containing portion containing waste liquid discharged from the liquid ejecting head. The carriage includes a plurality of liquid containers that contain the liquid and are mounted on the carriage in such a manner that a plurality of the liquid containers are arranged side by side with each other in the depth direction. A portion of the carriage overlaps the waste liquid containing portion in a vertical direction when the liquid ejecting head is outside the transport path.

A method of removing a printhead cartridge from a print module includes the steps of: rotating a first wing lever to effect linear sliding movement of a first ink coupling of the print module away from the printhead cartridge; rotating a second wing lever to effect linear sliding movement of a second ink coupling of the print module away from the printhead cartridge; and removing the printhead cartridge from the print module. The first and second wing levers each has an axis of rotation perpendicular to a direction of linear sliding movement of the first and second ink couplings.

A printing apparatus comprises: a printing unit configured to print onto a sheet by ejecting ink from a printing head; a maintenance unit configured to perform a maintenance operation capable of being performed in parallel with the printing performed by the printing unit; and a control unit configured to control the maintenance unit such that when the printing by the printing unit and the maintenance operation by the maintenance unit are performed in parallel, and the maintenance operation is not completed by the time the printing by the printing unit has ended, the maintenance operation is ended without being completed.

A recording apparatus includes a carriage equipped with a recording head that ejects ink to a sheet, a drive unit configured to move the carriage in a width direction of the sheet, an encoder configured to detect first information regarding a position or a velocity of the carriage that moves by the drive unit, an acceleration sensor arranged on the carriage and configured to detect second information regarding acceleration of the carriage, and a control unit configured to stop the carriage, based on the first information and the second information.

A printing device includes a printing portion, a maintenance portion, and a controller. The printing portion includes an ejection head and prints using ink. The maintenance portion performs maintenance on the ejection head. The maintenance involves consumption of ink. The controller has a manual maintenance mode and an automated maintenance mode. In the manual maintenance mode, the controller executes a maintenance using the maintenance portion in response to a maintenance command signal based on a manual operation. In the automated maintenance mode, the controller automatically executes a maintenance using the maintenance portion in response to a maintenance execution condition being met. Based on control information acquired, the controller switches an operating mode of the printing device from a first operating mode of selectively executing the manual maintenance mode and the automated maintenance mode to a second operation mode of executing the automated maintenance mode without executing the manual maintenance mode.

A maintenance device includes a plurality of heads that discharges liquid for printing. A cleaner selectively cleans the heads. A cleaning controller controls the cleaner. A determiner determines a cleaning time when the cleaner cleans one of the heads. An interruption-resumption controller controls the heads to interrupt printing at the cleaning time and resume printing when the cleaner finishes cleaning the one of the heads. The cleaning controller controls the cleaner to clean the one of the heads whenever the interruption-resumption controller controls the heads to interrupt printing at the cleaning time.

A system for in-line treatment of thread for use with a thread consuming device is provided. The system includes a treatment unit including at least a first and a second print head each being configured to dispense one or more coating substances onto the at least one thread when activated; and a control unit configured to determine if a maintenance sequence is to be performed on at least the first print head, and if so schedule said maintenance sequence on at least the first print head. A method is further provided.

A liquid ejecting system includes: a transport portion that transports a medium in a transport direction in a state in which the medium is supported on a medium supporting surface; a liquid ejecting portion that performs printing by moving in a scanning direction and ejecting a liquid from a nozzle with respect to the medium supported on the medium supporting surface; a designation portion for an operator to designate a designation range within a scanning area, the scanning area being configured to face the liquid ejecting portion that moves in the scanning direction and to include the medium and the medium supporting surface; and a control portion that sets a flushing area based on the designated designation range and performs a flushing operation of ejecting the liquid from the nozzle to the flushing area as a maintenance operation of the liquid ejecting portion.

A printing device includes a printing portion, a maintenance portion, and a controller. The printing portion includes an ejection head and prints using ink. The maintenance portion performs maintenance on the ejection head. The maintenance involves consumption of ink. The controller has a manual maintenance mode and an automated maintenance mode. In the manual maintenance mode, the controller executes a maintenance using the maintenance portion in response to a maintenance command signal based on a manual operation. In the automated maintenance mode, the controller automatically executes a maintenance using the maintenance portion in response to a maintenance execution condition being met. Based on control information acquired, the controller switches an operating mode of the printing device from a first operating mode of selectively executing the manual maintenance mode and the automated maintenance mode to a second operation mode of executing the automated maintenance mode without executing the manual maintenance mode.
