Abstract
An image forming apparatus includes a recording head which jets ink droplets, a head transporting mechanism which transports the recording head, and a control unit which controls the head transporting mechanism to reciprocate the recording head along a transporting path and controls the recording head to form an image on a sheet by jetting the ink droplets when the recording head passes over an image formation area within the transporting path. When the control unit controls the transporting mechanism to transport the recording head toward a turn-around point in the transporting path, the control unit decelerates the recording head in accordance with a first acceleration profile and a second acceleration profile which has a peak of deceleration higher than that of the first acceleration profile.
Claims6
An image forming apparatus comprising:
- a recording head configured to jet ink droplets onto a sheet;
- a head transporting mechanism configured to transport the recording head;
- and
- a control unit configured to control the head transporting mechanism to reciprocate the recording head along a transporting path, and control the recording head to form an image on the sheet by jetting the ink droplets under a condition that the recording head passes over an image formation area which is an area in the transporting path for forming the image on the sheet,
- wherein under a condition that the control unit controls the transporting mechanism to transport the recording head toward a turn-around point in the transporting path, the control unit is configured to control the head transporting mechanism to decelerate the recording head in accordance with a first acceleration profile from a deceleration-starting point at an upstream side of the turn-around point up to an end of the image formation area, and control the head transporting mechanism to decelerate in accordance with a second acceleration profile, which has a peak of deceleration higher than a peak of deceleration of the first acceleration profile, from the end of the image formation area up to the turn-around point.
An image forming apparatus configured to form an image by jetting ink droplets onto a sheet, comprising:
- a recording head configured to jet ink droplets;
- a head transporting mechanism configured to transport the recording head;
- and
- a control unit configured to control the head transporting mechanism to reciprocate the recording head along a transporting path, and also control the recording head to form an image on the sheet by jetting the ink droplets under a condition that the recording head passes over the image formation area which is an area in the transporting path to form the image on the sheet,
- wherein under a condition that the control unit controls the transporting mechanism to transport the recording head toward a turn-around point in the transporting path, the control unit is configured to control the head transporting mechanism to decelerate the recording head from a deceleration-starting point at an upstream side of the turn-around point, and in a case that an end of the image formation area is positioned between the deceleration-staring point and the turn-around point, the control unit is configured to control the head transporting mechanism to make a peak of deceleration in an interval from the end of the image formation area up to the turn-around point higher than a peak of deceleration in an interval from the deceleration-starting point up to the end of the image formation area.
