Abstract
An image forming device includes a recording head, a first pair of conveying rollers, a second pair of conveying rollers, and a conveyance controller. The conveyance controller controls the first and second pairs of conveying rollers to halt a conveying operation of the recording medium when a trailing edge of the recording medium has moved to or exceeded a position downstream from the nip position of the first pair of conveying rollers by a first prescribed distance during a first prescribed period of time running from a time instant when the trailing edge of the recording medium has passed through the nip position of the first pair of the conveying rollers.
Claims26
An image forming device comprising:
- a recording head that forms images on a recording medium having a width and a length, the recording head being disposed in a position along a recording medium conveying path;
- a first pair of conveying rollers that is disposed in a first position along the recording medium conveying path and conveys the recording medium with frictional force created at a nip position, the recording medium being conveyed while being oriented in a direction in which lengthwise of the recording medium is in parallel with a recording medium conveying direction;
- a second pair of conveying rollers that is disposed in a second position along the recording medium conveying path and conveys the recording medium with frictional force created at a nip position, the first position being upstream of the position in which the recording head is disposed and also of the second position with respect to the recording medium conveying direction, a distance between the first position and the second position being set shorter than the length of the recording medium;
- and
- a conveyance controller that controls the first and second pairs of conveying rollers, wherein the conveyance controller controls the first and second pairs of conveying rollers to halt a conveying operation of the recording medium when a trailing edge of the recording medium has moved to or exceeded a position downstream from the nip position of the first pair of conveying rollers by a first prescribed distance during a first prescribed period of time running from a time instant when the trailing edge of the recording medium has passed through the nip position of the first pair of the conveying rollers.
