Patent ID: 8672568

Claim:
A printing apparatus, which is capable of double-face printing to print images on both sides of a recording sheet, comprising: a printing unit, which is configured to print an image on one of the sides of the recording sheet; a sheet feeder, which is configured to feed the recording sheet to the printing unit; a discharge unit configured to receive settlement of the recording sheet with the image printed thereon; a sheet path, which includes a feeding path to guide the recording sheet fed from the sheet feeder to the printing unit, a discharge path to guide the recording sheet passing through the printing unit to the discharge unit, and a reversing path diverging from the discharge path and merging into the feeding path at an upstream position with respect to the printing unit along a direction of conveying the recording sheet, the sheet path guiding the recording sheet therealong and reversing the recording sheet by use of the reversing path and reverse-conveyance during a double-face printing operation; a manual sheet inlet, configured to receive manual insertion, by a user, of a recording sheet into the printing apparatus; a manual sheet path, which is configured to merge into the sheet path at a merging point, the merging point being at an upstream position with respect to the printing unit along the direction of conveying the recording sheet and guide the manually-inserted recording sheet to the merging point; a processor; and memory storing instructions that, when executed, cause the printing apparatus to function as: a detecting unit, which is configured to detect the manually-inserted recording sheet fed through the manual sheet inlet; a judging unit, which is configured to judge whether the detecting unit detects the manually-inserted recording sheet while the double-face printing operation is conducted with a preceding recording sheet; and a conveyer controller unit, which is configured to convey the preceding recording sheet in the double-face printing operation to the discharge unit without reversing when the judging unit judges that the detecting unit detected the manually-inserted recording sheet.
