Abstract
An electronic device includes a carriage conveyance unit, a sheet conveyance unit, a failure detection unit, a position detection unit, and a jam determination unit. The carriage conveyance unit includes a motor and conveys a carriage in a main scanning direction by a driving force of the motor. The sheet conveyance unit conveys a sheet in a sub-scanning direction which crosses the main scanning direction in which the carriage is conveyed. The failure detection unit detects a conveyance failure of the carriage. The position detection unit detects a position of the carriage in the main scanning direction. The jam determination unit determines whether or not the conveyance failure is due to jamming caused by interference between the carriage and the sheet, based on the position of the carriage detected by the position detection unit at a time when the conveyance failure is detected by the failure detection unit.
