An inkjet printer includes an endless transporting belt that transports a medium in a transport direction by supporting the medium and rotating, an ejecting unit that ejects ink onto the medium supported by the transporting belt, and a cleaning unit including a first brush for cleaning the transporting belt, a first cleaning liquid tank that stores cleaning liquid with which the first brush is impregnated, a second brush for cleaning the transporting belt, and a second cleaning liquid tank that stores the cleaning liquid with which the second brush is impregnated. The second cleaning liquid tank is disposed at a position lower than the first cleaning liquid tank in the vertical direction, and the cleaning unit is configured so that the cleaning liquid discharged from the first cleaning liquid tank is supplied to the second cleaning liquid tank.

Inkjet printer with dual cleaning units

A liquid ejecting apparatus RIM which ejects liquid onto a medium includes a carriage which includes a control substrate which configures at least a part of a control unit which controls driving of the entire liquid ejecting apparatus, a plurality of ejecting units which eject the liquid, a plurality of driving substrates which are connected to the control substrate, connected to the plurality of ejecting units in one-to-one correspondence, and drives the ejecting unit, an ejecting unit-driving substrate accommodating unit which accommodates the ejecting unit and the driving substrate, and a control substrate accommodating unit which accommodates the control substrate, in which the plurality of driving substrates are connected to the control substrate.

Liquid ejecting apparatus

A liquid ejecting apparatus which ejects liquid onto a medium includes a carriage which includes a control substrate configuring at least a part of a control unit which controls driving of the entire liquid ejecting apparatus, an ejecting unit which ejects the liquid, and a driving substrate which is connected to the control substrate and the ejecting unit, and drives the ejecting unit, in which the carriage is provided with a load absorbing unit which absorbs a physical load with respect to the ejecting unit from the driving substrate side. By adopting the liquid ejecting apparatus with such a configuration, it is possible to prevent a load from being applied to the ejecting unit from the driving substrate side.

By adopting the liquid ejecting apparatus with such a configuration, it is possible to prevent a load from being applied to the ejecting unit from the driving substrate side.

A printing apparatus includes ejection heads configured to eject a liquid onto a medium, a plurality of sub-units each including an ejection head row configured by a plurality of the ejection heads, and a plurality of maintenance sections configured to sequentially perform maintenance on the sub-units. The plurality of the maintenance sections are configured such that positions of at least two of the plurality of the maintenance sections are aligned with positions of at least two of the plurality of the sub-units, respectively, while the at least two of the plurality of the maintenance sections perform the maintenance.

Printing apparatus

A printing apparatus includes a belt mover for an endless belt which carries out a line feed of a recording medium, a feed amount calculator that calculates an amount of belt feed of the belt mover, and a movement amount measurer that measures actual amount of movement of the endless belt by image processing. The feed amount calculator calculates the amount of belt feed by which the endless belt is to be fed, on the basis of the amount of belt feed by which the endless belt has been fed and the actual amount of movement of the endless belt measured by the movement amount measurer. The belt mover moves the endless belt by the amount of belt feed calculated.

A printing apparatus includes ejection heads that eject a liquid onto a medium, a plurality of sub-units each including an ejection head row configured by a plurality of the ejection heads, and a plurality of maintenance sections that sequentially perform maintenance on the sub-units. For a head pitch that is a spacing between centers of the ejection head rows, a spacing between centers of mutually adjacent of the maintenance sections is an integer multiple of the product of the head pitch with the number of the ejection head rows provided to each of the sub-units.

A printing apparatus includes a belt mover for an endless belt that transports a recording medium, a feed amount calculator that calculates an amount of feed of the belt mover, a movement amount detection sensor as a movement amount measurer that measures actual amount of movement of the endless belt by image processing, a compensation table storer that stores a compensation table for compensating a transport error of the endless belt, and a control portion that calculates the amount of feed that is to bring about a predetermined amount of movement of the endless belt by using the feed amount calculator and by referring to the compensation table storer, moves the endless belt by using the belt mover on the basis of the amount of feed, compares the actual amount of movement of the endless belt measured by the movement amount detection sensor and the predetermined amount of movement.
