Abstract: An image forming device includes a memory, a memory controller, an error detector, a determiner, a print controller, a display, and a display controller. The memory controller acquires print information transmitted from an external device, and stores and controls the print information in the memory. The error detector detects a print error after start of printing of the print information. The determiner determines whether to execute sheet recovery processing to reprint a page in which the print error has occurred. The print controller controls a printing unit to execute the sheet recovery processing with the print information stored in the memory when a determination result to execute the sheet recovery processing is obtained. The display controller displays on the display a message indicating that the sheet recovery processing is not executed when a determination result not to execute the sheet recovery processing is obtained.

Abstract: In an image forming apparatus, an operation result output part outputs a result of operation of a component. An operation result information creation part creates operation result information by giving information identification character information, which is determined by the component or the result of operation of the component, to the result of operation of the component. An identifier table stores the information identification character information and a unique identifier related to each other and the result of operation of the component and a unique identifier related to each other. An operation result information conversion part reads the identifier related to the information identification character information from the identifier table and converts the operation result information into after conversion operation result information in which at least the information identification character information is replaced by the identifier.

Abstract: An image forming device includes a pump which supplies a recording fluid contained in a first container to a second container via a tube, and a control unit configured to perform rotation of a roller disposed in the pump to press the tube and feed the recording fluid in the tube. When a negative pressure in the second container is not formed by performing a first backward rotation of the roller by a predetermined amount, the control unit performs a forward rotation of the roller and performs a second backward rotation of the roller after an end of the forward rotation.

Abstract: An image forming apparatus includes a head to eject liquid droplets, a sub-tank having a container to store an amount of liquid supplied to the head, a negative pressure generator unit generating a negative pressure and an air introducing mechanism to introduce air, a main-tank to supply the amount of liquid into the sub-tank, a pressure detector unit to detect a pressure inside the sub-tank, and a controller to control an image forming operation using a remaining amount of liquid in the sub-tank while the main-tank is at an end status, where the controller determines whether the pressure inside the sub-tank is within a normal range, causes, if the detected pressure is not within the normal range, the air introducing mechanism to introduce air to raise the pressure inside the sub-tank, and causes the head to eject non-image forming liquid to cause the pressure to fall within the normal range.

Abstract: An image forming apparatus includes a voltage applying unit to apply a voltage to and charge a surface of transport belt, a leak judging unit to judge a charge leak on the surface of the transport belt, and a recovery operation unit to perform a charge leak recovery operation in which the transport belt is driven in a state where the voltage applying unit applies no voltage to the transport belt, if the leak judging unit judges that the charge leak is generated on the surface of the transport belt. The leak judging unit again judges whether the charge leak is generated on the surface of the transport belt after the recovery operation unit performs the charge leak recovery operation.

Abstract: An image forming apparatus includes ink cartridges, image forming units, an ink-remaining-amount manager, a maintenance determiner, an information writer, an ink-amount estimator, and a maintenance-executability determiner. If an ink near-empty or empty state occurs in one of the ink cartridges due to image formation, the ink-amount estimator estimates an amount of ink required to execute the maintenance on the other ink cartridges based on the at least one of the need for and the type of maintenance determined by the maintenance determiner. If the maintenance-executability determiner determines that the maintenance is unexecutable on at least one of the other ink cartridges based on the required ink amount and a remaining ink amount, the maintenance-executability determiner determines that the unexecutable ink cartridge is at an ink near-empty or empty state and stops writing or updating information indicative of a spent state on the memory of the unexecutable ink cartridge.

Abstract: An image forming device includes a pump which supplies a recording fluid contained in a first container to a second container via a tube, and a control unit configured to perform rotation of a roller disposed in the pump to press the tube and feed the recording fluid in the tube. When a negative pressure in the second container is not formed by performing a first backward rotation of the roller by a predetermined amount, the control unit performs a forward rotation of the roller and performs a second backward rotation of the roller after an end of the forward rotation.
