Wiping device and liquid discharge apparatus

A wiping device comprising:

• a web windable in a winding direction and a rewinding direction opposite to the winding direction, to wipe nozzle faces of multiple liquid discharge heads arranged in a width direction orthogonal to the winding direction;
• multiple pressing mechanisms arranged in the width direction corresponding to the multiple liquid discharge heads, each of the multiple pressing mechanisms movable between:
• a wiping position to cause the web to contact corresponding one of the nozzle faces of the multiple liquid discharge heads;
• and
• a retracted position to cause the web to be separated from the corresponding one of the nozzle faces;
• and
• circuitry configured to:
• store unused portion of the web at which a part of the multiple pressing mechanisms is at the retracted position during wiping in a memory;
• rewind the web in the rewinding direction to cause the unused portion of the web to face a part of the nozzle faces unwiped;
• and
• cause the part of the multiple pressing mechanisms corresponding to the unused portion of the web to move to the wiping position to bring the unused portion of the web into contact with the part of the nozzle faces unwiped.
