Rolled recording medium conveyance device, image forming apparatus, rolled recording medium conveyance method, and computer program product

A rolled recording medium conveyance method comprising:

• a conveyance process step in which a recording medium pulled out from the recording medium in a rolled state is conveyed with a forward conveyance direction corresponding to a direction in which the recording medium is pulled out;
• a first recording medium detection process step in which when an edge portion of the recording medium on an upstream side of the forward conveyance direction is not detached from a core portion of the rolled recording medium and an amount of the rolled recording medium equals a predetermined amount or less, a predetermined signal is output;
• a second recording medium detection process step in which it is determined whether or not the recording medium is presented on a downstream side of the first recording medium detection process step in the forward conveyance direction;
• a conveyance control process step in which when the predetermined signal is output in the first recording medium detection process step, the recording medium being pulled out in the conveyance process step is conveyed for a predetermined period of time in the forward conveyance direction, and
• a control process step in which the recording medium is conveyed in the forward conveyance direction or a reverse conveyance direction opposite from the forward conveyance direction in the conveyance process step, on the basis of a detection result by at least either the first recording medium detection process step or the second recording medium detection process step while or after the recording medium is conveyed for the predetermined period of time in the conveyance control process step.

A computer program product comprising a non-transitory computer-readable recording medium having a rolled recording medium conveyance program which causes a computer to execute a process comprising:

• a conveyance process step in which a recording medium pulled out from the recording medium in a rolled state is conveyed with a forward conveyance direction corresponding to a direction in which the recording medium is pulled out;
• a first recording medium detection process step in which when an edge portion of the recording medium on an upstream side of the forward conveyance direction is not detached from a core portion of the rolled recording medium and an amount of the rolled recording medium equals a predetermined amount or less, a predetermined signal is output;
• a second recording medium detection process step in which it is determined whether or not the recording medium is presented on a downstream side of the first recording medium detection process step in the forward conveyance direction;
• a conveyance control process step in which when the predetermined signal is output in the first recording medium detection process step, the recording medium being pulled out in the conveyance process step is conveyed for a predetermined period of time in the forward conveyance direction, and
• a control process step in which the recording medium is conveyed in the forward conveyance direction or a reverse conveyance direction opposite from the forward conveyance direction in the conveyance process step, on the basis of a detection result by at least either the first recording medium detection process step or the second recording medium detection process step while or after the recording medium is conveyed for the predetermined period of time in the conveyance control process step.
