Patent ID: 7513501

Claim:
Paper feeding device for dot printers, for example for an ink jet photographic printer, said paper feeding device comprising: a paper feeding motor, a picking mechanism including a picking roller motorized by the paper feeding motor, the picking roller adapted to pick a sheet of paper from a stack and move the paper in a picking direction along a picking path, at least one motor roller located downstream of the picking roller along the picking direction, and motorized by the paper feeding motor, the motor roller adapted to retract the sheet in a retraction direction opposite the picking direction, the motor roller further adapted to move the sheet through the printer in a printing direction consistent with the picking direction, a deflector adapted to contact the sheet when the motor roller retracts the sheet in the retraction direction, the deflector adapted to deflect the sheet onto an alternative path to the picking path, a changeover mechanism arranged downstream of said paper feeding motor and suitable for actuation in response to predetermined operating conditions of the printer to operate the picking roller to move the sheet at high speed during movement in the picking direction, to operate the at least one motor roller to move the sheet at high speed during movement in the retraction direction, and to operate the at least one motor roller to move the sheet at low speed during movement of the paper in the printing direction.
