Abstract: An image forming apparatus creates a drive waveform containing a first pulse to discharge the droplet and a second pulse to cause a liquid to flow within a recording head. A data creation part creates data to select a first or second droplet discharge pulse. The first droplet discharge pulse contains the first pulse and the second pulse. The second droplet discharge pulse does not contain the second pulse. When the first or second droplet discharge pulse is selected in a subsequent drive period and when neither the first nor second droplet discharge pulse is selected in a current drive period, the second pulse is selected in the current drive period when selecting the second droplet discharge pulse in the subsequent drive period, and the second pulse is not selected in the current drive period when selecting the first droplet discharge pulse in the subsequent drive period.

Abstract: In an image forming device, the print head performs a bi-directional printing including a first print while being moved in the first direction and a second print while being moved in the second direction. The conveying mechanism conveys the recording medium a first amount prior to the first print and a second amount prior to the second print. The relative tilt offset amount indicates an offset between tilts of the print head when the print head is moved in the first direction and when the print head is moved in the second direction. The tilt calibration value is determined based on the relative tilt offset amount. The conveying amount setting unit sets the first amount to a calibrated amount obtained by calibrating a prescribed amount based the relative tilt offset amount or the relative tilt calibration value prior to the first print and that sets the second amount to the prescribed amount prior to the second print.

The distance L from the edge of the transportation path to the start printing position of the inkjet head is also set to L=Lm (where Lm is the size of the margin on the paper). When the paper width is contained in the received data, the position where the paper is set is the center reference, and the received paper width is set as the paper width of the paper used for printing.

Abstract: A liquid ejecting head inspection apparatus detects malfunction of a liquid ejecting head that discharges liquid droplets. The liquid ejecting head inspection apparatus includes a liquid droplet landing portion on which a discharged liquid droplet can land. An electric change detecting unit detects an electric change in the liquid droplet landing portion.

A non-landing unit ensures that no liquid droplet lands on the liquid droplet landing portion when the discharging drive signal is applied to the driving element. A judging unit judges whether the liquid ejecting head inspection apparatus functions properly based on activity of the electric change detecting unit.
