Abstract
An image formation device (facsimile machine, printer, copier, etc.) is provided, which is capable of reducing the amount of ink ribbon rolled up for the removal of slack of the ribbon. When a ribbon roll-up process is started, the operation mode of the image formation device is first set to a ribbon roll-up mode in which a ribbon roll-up spool is driven without driving a platen. The slack of the ribbon is removed by driving the ribbon roll-up spool to roll up the ribbon without driving the platen, which can reduce the amount of ribbon rolled up for the removal of the slack (the amount of ribbon wasted).
