Abstract: An inkjet printer includes: a print head; a print data storing unit; a print executing unit; a maintaining unit; a maintenance necessity determining unit; and a printing results inquiring unit. The print head is formed with one or more ink ejection opening. The print data storing unit stores inputted print data. The print executing unit executes a printing operation with the print head based on print data stored in the print data storing unit. The maintaining unit restores the ink ejection state of the print head. The maintenance necessity determining unit determines whether or not it is necessary to perform an operation for restoring the ink ejection state with the maintaining unit. The printing results inquiring unit inquires whether to allow the printing results of a printing operation executed by the print executing unit when the maintenance necessity determining unit determines that it is necessary to restore the ink ejection state of the print head.

Abstract: An inkjet printer includes: a print head; a maintaining unit; a timing unit; a notifying unit; a maintenance command determining unit; and a maintenance operation executing unit. The print head is formed with one or more ink ejection opening for printing a printing medium by ejecting ink through the ink ejection opening. The maintaining unit restores the ink ejection state of the print head by flowing ink through the ink ejection opening. The timing unit keeps track of an elapsed time after the maintaining unit has executed a maintenance operation. The notifying unit notifies a user when it is time to execute a maintenance operation if the elapsed time measured by the timing unit exceeds a prescribed time. The maintenance command determining unit determines whether or not the user has issued a command to execute a maintenance operation with the maintaining unit after the notifying unit has issued a notification.

Abstract: A recording apparatus includes: a carriage having a recording head, a movement unit that reciprocally moves the carriage, a carriage detection unit, a point-of-origin detection unit that detects the position of a point of origin of the carriage, a regulation unit capable of restricting the movement of the carriage, and a control unit that selectably performs one of a first initialization processing and a second initialization processing longer in time than the first initialization processing. The control unit selects one of the first initialization processing and the second initialization processing on the basis of whether movement of the carriage is restricted and whether a travel distance of the carriage corresponds to a predetermined distance, when the movement unit moves the carriage from a position of origin toward the regulation unit.

Abstract: In a facsimile device, a CPU determines whether or not a recording sheet is conveyed normally based on the conveyance state detected by a detecting portion. When the CPU determines that the recording sheet has been conveyed normally, the CPU increases the conveying speed in a stepwise manner based on the current conveying speed until the conveying speed reaches maximum speed. Therefore, according to the present facsimile device, when conveyance of the recording sheet is normally performed at a specified conveying speed, the number of failures of conveyance of the recording sheet can be reduced compared to a facsimile device, in which the conveying speed is set at maximum speed of conveyance by a sheet feed roller. Also, the recording sheet can be conveyed at as high speed as possible.

Abstract: An image forming apparatus includes a formation unit and an overlap order number assignment unit. The formation unit divides a predetermined image and forms divided images of the predetermined image on plurality sheets of recording paper in a divided manner. The formation unit forms the divided images such that, among the plurality sheets of recording paper, on which the divided images are formed by the formation unit, at least one of the plurality sheets of recording paper includes an overlap portion used for overlapping the at least one of the plurality sheets of recording paper with a remainder of the plurality sheets of recording paper. The overlap order number assignment unit assigns the at least one of the plurality sheets of recording paper with an overlap order number, indicating an overlap order for overlapping the plurality sheets of recording paper, in the overlap portion.

Abstract: A carriage drive control device is provided which moves a carriage at a constant speed in a recording area for recording operation and which moves the carriage to a target stop position in a better way for non-recording operation. A controlled variable of actuator is calculated based on a speed error between a target speed and a moving speed of the carriage. The target speed is set based on a position error between the target stop position and a current position of the carriage, and is not more than a predetermined first speed. When the actuator starts moving the carriage for recording operation, a control rule used for calculation of the controlled is set to a first control rule, and when the actuator starts moving the carriage for non-recording operation, the control rule is set to a second control rule.

The recording sheet is fed by the predetermined amount after the first pattern is formed. Thereafter, a second print pattern that is formed by part of the plurality of print lines on a downstream side after the recording sheet is fed. At least a part of the first print pattern overlaps a part of the second print pattern.

Abstract: A carriage motor is driven with a predetermined duty value and it is determined whether a carriage is moved. If it is determined that the carriage is moved, a lower duty value is set. If it is determined that the carriage is not moved, a higher duty value is set, in order to obtain the duty values at the time when the carriage is and is not moved. The duty values when the carriage is moved and is not moved, are stored, as alternative characteristic values, in an EEPROM in association with positional information of duty value detection position. Therefore, quality control may be properly performed by checking the stored duty values.
