A printing apparatus includes: a cap member configured to be switched between a capped state in which an ink discharge port of a printhead is covered by the cap member and a non-capped state; a conveyance unit configured to convey a print medium to the printhead; and a cutting unit configured to cut the print medium on which an image is formed by the printhead. A cutting setting for operating the cutting unit can be set in advance based on a cutting instruction of a user. In a case in which the cutting setting is set, the cap member waits for the cutting instruction in the non-capped state, and the cap member is switched to the capped state when a wait time for the cutting instruction reaches a predetermined time.

Printing apparatus, and control method

For appropriate execution of processing depending on a condition in an image printing apparatus, the image printing apparatus includes a mounting unit on which a tank is mountable, a print head, a sub tank which receives ink from the tank and supplies the ink to the print head, and a refilling unit which refills the sub tank with ink from the tank. In a case where a tank mounted on the mounting unit is noncompliant with a predetermined condition, the control unit prevents the refilling unit from refilling the sub tank with ink from the tank. In contrast, in a case where a tank mounted on the mounting unit is compliant with the predetermined condition, the control unit causes the refilling unit to refill the sub tank with ink from the tank.

Image printing apparatus, control method of image printing apparatus and processing apparatus

A printing apparatus is provided. A mount unit is able to mount a consumable. A communication unit is able to communicate with a server system. A request unit requests, to the server system via the communication unit, service-related information related to the consumable. A reception unit receives, via the communication unit, the service-related information transmitted from the server system with respect to the request. A determination unit determines, in a case in which a state of the communication unit has shifted from a first state in which communication with the server system is disabled to a second state in which communication with the server system is enabled, whether a request for the service-related information by the request unit is required, based on a reception history of the service-related information of the reception unit.

Printing apparatus and method of controlling the same

The image forming apparatus manages information on a consumable item by a management chip and includes a control unit configured to control the management chip, and the management chip includes: a chip-side storage unit whose storage area is made up in units of blocks; a simultaneous writing unit configured to simultaneously write information on the consumable item in units of the blocks in the chip-side storage unit; and a predetermined unit writing unit configured to write information on the consumable item in predetermined units smaller than the block unit in the chip-side storage unit, and the control unit performs control so as to write information on the consumable item by the simultaneous writing unit at timing at which there is time constraint and performs control so at to write information on the consumable item by the predetermined unit writing unit at timing at which there is no time constraint.

Image forming apparatus and management method of consumable item

A printing apparatus comprises: a maintenance unit that performs a maintenance operation for a printhead that includes a plurality of operation patterns; a storage unit that stores information indicating which of the operation patterns was performed when the maintenance operation was performed; a timer that measures an elapsed time from a previous printing operation; a determination unit that determines whether or not to execute the maintenance operation; and a control unit that controls the operation patterns of the maintenance operation to be performed in accordance with the elapsed time and the information, wherein in a case where a scanning instruction is received and the determination unit determines to execute the maintenance operation, the control unit performs control for executing the maintenance operation not in accordance with the elapsed time but in accordance with the information before the operation of scanning.

Printing apparatus, method of controlling same, and non-transitory computer-readable storage medium

The printing apparatus according to the present invention includes a reading unit configured to read, in a case of detecting a mounting position at which a mounting state of a printing material cartridge has changed from non-mounting to mounting, by performing polling for a plurality of printing material cartridges, color information from the printing material cartridge mounted at the detected mounting position, and a notification unit configured to notify, in a case where the printing material color indicated by the color information is different from the printing material color corresponding to the detected mounting position, a user that the printing material cartridge is mounted incorrectly. The reading unit omits processing to read color information from the printing material cartridge mounted at the detected mounting position in a case where the mounting state of the printing material cartridge mounted at the detected mounting position is maintained as mounting.

Printing apparatus performing polling to detect mounting and unmounting of cartridges, and control method of printing and storage medium

A printing apparatus comprises a maintenance unit configured to execute a maintenance operation between a completion of printing on a preceding sheet serving as the printing sheet fed from a stacking unit first and a start of printing on a succeeding sheet serving as the printing sheet fed from the stacking unit next, and a determination unit configured to determine whether to execute the maintenance operation, wherein the determination unit determines, based on a feeding method of the succeeding sheet, whether to execute the maintenance operation.

Printing apparatus and control method thereof

There is provided an ink jet printing apparatus that does not give poor usability to users and a method for controlling the same. To achieve this, in recovery processing performed multiple times to recover an ejection state, in a case where a printing instruction is inputted, the recovery processing is suspended in an amount smaller than an amount required for recovery, depending on an amount of ink in an ink tank.

Ink jet printing apparatus and method for controlling the same

A printing apparatus includes a main tank for containing ink; a sub tank for containing ink supplied from the main tank and containing ink to be supplied to a print head; a detection unit configured to detect an ink amount in the sub tank; and a filling unit configured to perform ink filling operation that fills the sub tank with ink from the main tank by driving a driving unit, in a case where the detection unit detects the ink amount in the sub tank that is less than a first predetermined amount, wherein in a case where the ink amount in the main tank is less than a second predetermined amount, the filling unit drives the driving unit at smaller drive amount than that in a case where the ink amount in the main tank is greater than the second predetermined amount.

Printing apparatus and ink amount detection method

An inkjet recording apparatus that performs preliminary discharge operation without a carriage and a recording medium interfering with each other is provided. The inkjet recording apparatus performs, at a center region in a conveyance direction of a recording medium, the preliminary operation at a position according to an edge portion of the recording medium obtained by an optical sensor. Further, the inkjet recording apparatus performs, at a leading edge region and a trailing edge region of a recording medium, the preliminary operation at a position based on input data.

Inkjet recording apparatus

An inkjet recording apparatus may include a recording unit, an ink receiver, and a control unit. The recording unit records an image on a sheet by causing a recording head including a plurality of nozzle arrays to reciprocate along a surface of the sheet in a direction in which the plurality of nozzle arrays is arranged. The ink receiver receives ink ejected outside the sheet in preliminary ejection from the recording head. Depending on a recording region on the sheet and which of the plurality of nozzle arrays is or are to be used for recording, the control unit determines a reversing position at which the recording head is reversed in direction of the reciprocation such that all of the plurality of nozzle arrays pass over the ink receiver in a single scan included in the reciprocation.
