The apparatus includes a cleaning section that includes a cleaning material for cleaning a transportation belt, which transports a recording target medium, by contact with the transportation belt. The cleaning section is capable of switching between a contact state, in which the cleaning material is in contact with the transportation belt, and a non-contact state, in which the cleaning material is not in contact with the transportation belt. The cleaning section is capable of performing renewal operation. The renewal operation is operation of renewing a contact region of the cleaning material, that is, a region of contact with the transportation belt, from a region that has already been used to a region that has not been used yet.

A waste liquid box management method sets a type of ink to be contained in a container, for a waste liquid box that includes a coupling portion coupled to a printer, the container containing ink discharged from the printer via the coupling portion, and a storage unit. The waste liquid box management method individually allocates different storage regions, in the storage unit, to a plurality of ink types, writes predetermined type specification data into a selected storage region, that is the storage region allocated to the ink type to be contained in the container, and inhibits writing to the storage region other than the selected storage region in a state in which data other than the type specification data is stored therein.

The invention relates to a method of cleaning a fluid circuit in an inkjet printer that comprises a print head connected to the fluid circuit through an umbilical (19), and also comprises means (50) of recovering fluid from the print head (1), this method comprising at least sending solvent to said fluid recovery means (50), without making this solvent flow in the umbilical or in the print head.

A cleaning fabric wound on a roll (12) is use for cleaning printing cylinders (2, 3, 4) of a printing system (1). The cleaning fabric (13) includes a liquid absorbable material configured to be soaked with a cleaning liquid containing a polar additive configured to make the cleaning liquid polar. The roll (12) of cleaning fabric (13) is included in a cleaning cassette (10) which is movable between an idle position out of contact with the printing cylinders, and an active position in which the cleaning fabric (13) included in the cassette (10) is in contact with a printing cylinder to be cleaned.
