In the above-mentioned embodiments, the LBP has been described as an example, but the present invention is not limited to this and can be applied to other printing devices (inkjet, dot matrix, etc.).

The present invention may be applied to a network system composed of a plurality of devices or an apparatus composed of a single device.

Further, it goes without saying that the present invention can also be applied to the case where it is achieved by supplying a program to a system or an apparatus.

According to the first embodiment, in the printing apparatus having the operation panel, when a paper jam occurs, a means for notifying the operator of the paper jam error message and instructing execution of the forced paper discharge mode, During the printing process, there is a means to execute forced paper ejection by the operator's operation on the operation panel, and a means to judge whether or not the paper jam is solved and to display the fact if it is resolved. When a paper jam occurs in the paper, the operator can discharge the paper only by the operation on the operation panel, so that the light paper jam can be eliminated without much labor compared to the related art.

Further, according to the second embodiment, in a printing apparatus having means for performing bidirectional communication with a host computer connected by a communication line, if a paper jam occurs during printing processing, the host side is A means for notifying the paper jam, a means for prompting execution of the forced paper ejection mode, a means for receiving and executing the forced paper ejection command from the host side, a means for judging whether or not the paper jam is solved, and the judgment result. If a paper jam occurs during the printing process, a forced paper ejection command from the host side is temporarily received and executed to eliminate the slight paper jam, thereby eliminating the slight paper jam. However, it is possible to greatly reduce the amount of labor that has been spent (removing the jammed paper by going to the place where the printing device is located).

Further, according to the third embodiment, when paper jam occurs during the printing process, means for automatically executing forced paper ejection and determining whether or not the paper jam is eliminated by the means Means for performing a process based on the determination result, and if a paper jam occurs during the printing process, forcibly forcibly discharge the paper for the time being to bother the operator. It is possible to eliminate a slight paper jam.

As described above, the first aspect of the present invention
According to the invention, when the first judging means judges that there is a jam and the driving of the conveying means is stopped, the mode display means displays the shift to the forced discharge mode for forcibly discharging the jammed recording medium. In accordance with an instruction to execute the forced ejection mode by the instructing means, the conveying means in which the ejecting means is stopped is restarted to start the forced ejection of the recording medium in the jam, and during the forced ejection. When the second determination unit determines that the jam has been eliminated, the message display unit displays the jam elimination message on the display unit. Therefore, when a slight jam occurs, an automatic cancellation instruction from the user is issued. It is possible to clear the jam and notify the user that the printing process is ready.

According to the second invention, when the first judging means judges that there is a jam and the driving of the conveying means is stopped,
The mode display means informs the external device of the transition to the forced ejection mode for forcibly ejecting the jammed recording medium, and the ejection means is restarted based on the forced ejection command from the external device. Then, the forced ejection of the recording medium being jammed is started, and during the forced ejection, when the second determination means determines that the jam has been eliminated, the message display means displays the jam elimination message on the display section. Therefore, when a slight jam occurs, the jam can be released according to the automatic release instruction command from the user on the external device side, and it is possible to clearly indicate to the user that print processing is possible.

According to the third invention, when the first judging means judges that there is a jam and the driving of the conveying means is stopped,
A message is displayed when the second determination unit determines that the jam has been eliminated during the forced ejection of the jammed recording medium by restarting the conveyance unit in which the ejection unit is stopped. Since the display unit displays the jam elimination message on the display unit, when a slight jam occurs, the jam can be automatically released and it is possible to clearly indicate to the user that the print processing can be performed.

According to the fourth aspect of the invention, the message display means displays a message for causing the operator to cancel the jam when the second judging means judges that the jam has not been eliminated. Is displayed, it is possible to clearly indicate to the user that a serious jam has occurred and a manual release operation is required.

According to the fifth aspect of the invention, when the second determining means determines that the jam has not been resolved, the notifying means sends a message for causing the external device to cancel the jam by the operator. Since the notification is given, it is possible to clearly indicate to the user on the external device side that a serious jam has occurred and a manual release operation is required.

According to the sixth aspect of the invention, when it is judged that there is a jam, the drive of the conveying means is stopped and the shift to the forced ejection mode for forcibly ejecting the recording medium being jammed is displayed on the display section. If the jammed state is determined during the forced ejection, the recording medium in the jam is forcibly ejected again by re-trying the transporting unit that is stopped based on the instruction to execute the forced ejection mode. Since a jam elimination message is displayed on the display unit, when a minor jam occurs, the jam can be canceled according to the automatic cancellation instruction from the user, and the process that clearly indicates to the user that printing can be performed is programmable. Can be executed.

According to the seventh aspect of the invention, when it is judged that there is a jam, the drive of the conveying means is stopped and the external device is notified of the shift to the forced ejection mode for forcibly ejecting the recording medium being jammed. Then, based on the forced ejection command input from the external device, the resting transporting means is retested to forcibly eject the recording medium in the jam, and it is determined that the jam has been eliminated during the forced ejection. In this case, since the jam elimination message is notified to the external device, the jam is released according to the automatic release instruction from the user of the external device, and the process for clearly indicating to the user that the printing process is possible is executed in a programmable manner. Can be made.

According to the eighth invention, when it is judged that there is a jam, the driving of the conveying means is stopped and the stopped conveying means is retested to forcibly eject the recording medium in the jam. During the forced discharge, when it is determined that the jam has been eliminated, a jam elimination message is displayed on the display unit, and when a slight jam occurs, the jam is automatically released, so that print processing is possible. It is possible to programmatically execute a process that clearly indicates to the user.

Therefore, if a paper jam occurs during the printing process, the paper is automatically forcibly discharged for the time being and the slight paper jam is eliminated, so that the operator's labor for processing the paper jam is greatly increased. There are effects such as reduction.
