In an example of the disclosure, a cleaning system for a printhead includes a web of material movable in a web direction. The web has a first side for wiping a printhead face. The cleaning system includes a dispensing apparatus to dispense a liquid upon the web. The cleaning system includes a scraper element for scraping liquid from the web and includes a collector element with a trough. The collector element is to cause collection of liquid scraped from the web to collect in the trough. The cleaning system includes a pusher element to push against the second side of the web and thereby cause the first side of the web to wipe the printhead face

An inkjet printing apparatus includes a head unit including a print head provided with an ejection opening surface for ejecting ink and performing a print operation with respect to a print medium, a platen unit including a platen having a support surface to support the print medium opposite to the ejection opening surface in a case in which the print head performs the print operation, and a spacer member configured to define a print gap between the ejection opening surface and the support surface by abutting against the head unit. A cap member caps the ejection opening surface, and a cap moving unit moves the cap member with respect to the ejection opening surface. In addition, an adjusting member adjusts the print gap by moving the spacer member in association with an operation in which the cap moving unit moves the cap member.

In an example, a service station may comprise a conveyor movable along or about a conveyor path. Example service station may further comprise a first service module removably installed on the conveyor, and a second service module removably installed on the conveyor. The conveyor may move the first service module and the second service module along the conveyor path. The example service station may further comprise a lifter disposed in a lifting zone along the conveyor path to lift one of the first service module and the second service module from a stowed position to an operating position if the first service module or the second service module is disposed in the lifting zone along the conveyor path.

A head cleaning device includes: a porous cleaning roller that rotates around a cylindrical axis while a cylindrical side circumferential surface is in pressure contact with a nozzle surface of an ink head to clean the nozzle surface; a storage tank that immerses a lower part of the cleaning roller in a cleaning liquid stored therein; a unit moving mechanism that moves a cleaning unit including the storage tank and the cleaning roller in a direction perpendicular to the axis of the cleaning roller; a hardware processor that controls a rotation speed [vr] of the cleaning roller and a moving speed [vx] of the storage tank and the cleaning unit; and a composition acquisition part that acquires a change in composition of the cleaning liquid in the storage tank due to mixing of ink supplied from the nozzle surface through the cleaning roller.

A rotary wiper assembly for a fluid-ejection printhead that has fluid-ejection nozzles includes one or more wipers and a rotatable shaft to which the wipers are at least indirectly attached. The rotatable shaft is to rotate the wipers to a static wiping position. While the wipers are stationary in the static wiping position, the fluid-ejection printhead is to move back and forth in relation to the wipers while the wipers are not to move, to cause the wipers to come into contact with the fluid-ejection nozzles to wipe material from the fluid-ejection nozzles.

There is provided an image recording apparatus including: a head; a maintenance unit; and a controller. The maintenance unit includes a wiper tank and a flushing tank. A first tank is one of the wiper and flushing tanks and a second tank is remaining one of the wiper and flushing tanks. The controller is configured to perform a first processing of cleaning the first tank, under a condition that an elapsed time is less than a threshold value, the elapsed time being a time elapsed since cleaning of the second tank or since a predetermined processing performed first after the cleaning of the second tank, and is configured to perform a second processing of cleaning the second tank by adding the cleaning liquid to the first tank, under a condition that the elapsed time is not less than the threshold value.

An ink cartridge clean device including a housing, a work platform, at least one ink stack and at least one ink absorption pad clean element. The housing has a first sidewall and a second sidewall opposite to each other, and an accommodation groove is defined by the housing. The work platform is disposed in the accommodation groove and has two lateral surfaces opposite to each other, and each lateral surface has at least one stopper. The ink stack is disposed on the work platform, and has an ink absorption pad. The ink absorption pad clean element is rotatably connected with the first sidewall and the second sidewall. When the work platform is adjusted from a first position to a second position, the ink absorption pad clean element is rotated, so that the corresponding ink absorption pad is cleaned, thereby preventing the residual ink from contaminating or blocking the ink cartridge.

This invention aims to propose a structure excellent in the maintenance operability of a cleaning member in a printing apparatus provided with the cleaning member for cleaning at least one of a wiper and a cap. In a printing apparatus according to the invention, a cleaning member for cleaning a wiper or a cap of a maintenance part is integrated with a printing head in a relative movement between the printing head and the maintenance part and arranged to at least partially overlap a movement path of the object to be cleaned with respect to the printing head and moves to outside the conveyance path integrally with the printing head when the printing head is moved from the inside position to the outside position.

An image forming apparatus that discharges droplets, while moving a recording head relative to a recording medium in a main scanning direction and a sub-scanning direction, to form an image, includes: a carriage; a first recording head that has a first discharge face having a hole, is disposed on the carriage, and discharges a first droplet containing resin through the hole; a second recording head that has a second discharge face having a hole, is disposed on the carriage, and discharges, through the hole, a second droplet containing resin less than the resin contained in the first droplet; a first cleaning device that wipes the first discharge face to clean the first recording head; and a second cleaning device that is different from the first cleaning device and that wipes the second discharge face to clean the second recording head.

A wiping module includes a wiping portion and a cleaning portion. The wiping portion includes a wiping member wiping a liquid discharge head that discharges a liquid from a nozzle provided on a nozzle surface, a storage support portion supporting the wiping member and configured to store the liquid by the wiping, and a movement support portion mounting the storage support portion and configured to reciprocate along a wiping direction, which is a direction in which the wiping is performed. The cleaning portion cleans the wiping member. The cleaning portion includes a cleaning member and a guide portion guiding the cleaning member. The cleaning member is configured to follow a movement of the wiping portion in the wiping direction and to scrape off the liquid adhering to the wiping member while being guided by the guide portion.
