摘要： An image forming apparatus includes an apparatus body, a recording head, a sub tank, a carriage, a main tank, a liquid feed device, a displacement member, a first detector, a second detector, a detection retainer, a liquid consumption amount measuring device, and a supply controller. The measuring device measures a consumption amount of liquid in the sub tank when the displacement member displaces from a first position in a direction in which the consumption amount of liquid in the sub tank decreases. When a detection output of the first detector continues to be, for a predetermined time or number of times, in a detection state in which the first detector detects the displacement member and shifts from the detection state to a non detection state in which the first detector does not detect the displacement member, the measuring device starts measuring the consumption amount of liquid in the sub tank.

摘要： An image forming apparatus includes an apparatus body, a recording head, a head tank, a carriage, a main tank, a liquid feed device, a supply controller, a displacement member, a first detector, and a second detector. When a consumption amount of liquid in the head tank reaches a threshold value, the controller controls the feed device to start supplying the liquid from the main tank to the head tank. When printing operation is not performed and the displacement member is at a position at which a remaining amount of the liquid in the head tank is smaller than when the displacement member is at a first position, the controller controls the feed device to supply the liquid until the displacement member is placed at the first position or a position at which the remaining amount of the liquid is greater than when the displacement member is at the first position.

摘要： In an image forming apparatus, a liquid supply control processor controls to detect and store a difference amount corresponding to a displacement amount of a displacing member between a position detected by a first sensor and another position detected by a second sensor; measure a consumed liquid amount; start the liquid supply upon the consumed liquid amount reaching a predetermined threshold so as to supply the difference amount after the first sensor has detected the displacing member; and stop the liquid supply when the first sensor does not detect the displacing member before a preset predetermined time has passed. The control processor controls the image forming apparatus such that, when the liquid supply is performed without using the second sensor, using a first and second predetermined threshold times and the first threshold time is set longer than the second threshold time.

摘要： An image forming apparatus includes a body, a recording head, a sub tank, a carriage, a main tank, a liquid feed unit, a displacement member, first and second detectors, first to third calculation units, a determination unit, and a supply control unit. When the first detector detects the displacement member, the determination unit determines a main scanning position of the carriage at which consumption amount of the liquid is equal to an amount corresponding to a difference calculated by the second unit, based on a relation calculated by the third unit. The control unit causes the feed unit to start supply of the liquid from the main tank to the sub tank when the carriage arrives at the main scanning position, and stop the supply when the liquid is supplied at an amount corresponding to a difference detected by the first unit after the first detector detects the displacement member.

摘要： An image forming apparatus includes: a print head; a head tank; a carriage; a main tank; a pump; a displaceable member or feeler; a first sensor; a second sensor; a controller to supply an amount of liquid ink corresponding to the displacement difference amount of the feeler to the head tank; and an environmental condition detector. The controller stores the environmental condition when the displacement difference amount is stored; corrects the stored displacement difference amount when a change in a current environmental condition relative to the stored environmental condition is more than a previously set first threshold amount and below a previously set second threshold amount being larger than the first threshold amount; and detects and stores the displacement difference amount again when the change in the current environmental condition relative to the stored environmental condition exceeds the second threshold amount.

摘要： In an image forming apparatus, a first detection part and a second detection part, each for detecting a position of a displacement member that changes its position according to a remaining amount of liquid in a sub-tank, are provided to a carriage carrying the sub-tank and a recording head, and a body of the image forming apparatus, respectively. A first position is a position of the displacement member detected by the first detection part such that the remaining amount of liquid in the sub-tank is smaller than that at a second position detected by the second detection part. The liquid is supplied to the sub-tank of a differential supply amount, corresponding to a displacement amount of the displacement member between a position detected by the first detection part and a position detected by the second detection part, after the first detection part detects the displacement member.
