Patent ID: 8430584

Claim:
An electronic device comprising: a carriage conveyance unit comprising a motor and configured to reciprocate a carriage along a main scanning direction by a driving force of the motor; a sheet conveyance unit configured to convey a sheet in a sub-scanning direction perpendicular to the main scanning direction along which the carriage is reciprocated; a failure detection unit configured to detect a conveyance failure of the carriage; a position detection unit configured to detect a position of the carriage in the main scanning direction; and a jam determination unit configured to determine whether 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 and a scanning direction of the carriage at a time when the conveyance failure is detected by the failure detection unit, wherein the jam determination unit determines that the conveyance failure is due to jamming caused by interference between the carriage and the sheet when a leading end of the carriage in the main scanning direction is detected within a predetermined specific area on a carriage conveyance path at the time when the conveyance failure is detected, and wherein the specific area is defined within a sheet passing area, which is an area in the carriage conveyance path that faces the sheet conveyed in the sub-scanning direction by the sheet conveyance unit.
