Abstract:
1. A printing apparatus, comprising: a sheet-feeding system; a sheet-transporting system, comprising a sheet-circulating path and a transporting mechanism, for receiving a recording medium from the sheet-feeding system and transporting the recording medium through an image forming system, wherein the transporting mechanism moves the recording medium along the sheet-circulating path; said image forming system, in the sheet-circulating path, forming an image on the recording medium; a sheet-controlling device, disposed between the sheet-feeding system and the sheet-transporting system, the sheet-controlling device controlling an entry of a sheet into the sheet-transporting system; a sheet-detection device, disposed between the sheet-feeding system and the sheet-transporting system; a first driving system for driving the sheet-controlling device; a second driving system for driving the transporting mechanism; and a controller, wherein the controller upon receiving an error signal, which is sent from the sheet-detection device when the sheet-detection device detects of a sheet-feeding error, signals the sheet-controlling device to inhibit the entry of the sheet into the sheet-transporting system and signals the transporting mechanism to continue an operation of the transporting mechanism; wherein the controller, which upon receiving the error signal from the sheet-detection device signals the transporting mechanism to continue the operation of the transporting mechanism, so that the transporting mechanism and the image forming system finish a printing process for the recording medium until print data are completely printed on the recording medium.
