When each sheet is printed and the engine has placed the sheet in a printer bin, the print engine sends a “Print Complete” signal to the printer controller to indicate the associated sheet is complete. However, since most printer bins are not equipped with sensors to detect when a sheet has arrived in a bin, many printers use an existing sensor in the printer’s paper path located closest to the selected bin as a trigger for this signal. For example, many laser printer engines send the “Print Complete” signal when the trailing edge of a sheet crosses the sensor located in the area of the fuser.
When the Cancel Job operation is selected, the printer identifies the next sheet for which “Print Complete” will be received and cancels the print job associated with the identified sheet.
Note: The sheet that is currently printing and any other sheets in the path are canceled and ejected.
Note: Unlike a operator panel reset, the host application should not be instructed to stop sending printer data when a cancel job operation is selected.
The cancel job operation is in the control panel JOB MENU. This menu can be accessed while the printer is in the ready (or idle state), the waiting state, the busy state, and while many intervention conditions as well as status conditions are displayed.
When a job is canceled:
•After the printer identifies which job is canceled, the printer determines whether the canceled job has ended or has been terminated.
•If the canceled job has ended or has been terminated, all sheets belonging to the canceled job for which the physical printing process has not yet begun are canceled, and the printer immediately begins processing the next print job.
•If the canceled job has neither ended nor been terminated:
–A user may stop the canceled job by executing a Front Panel Reset operation. After reset processing is complete, the printer begins processing the next print job.
–If the host computer continues to send data which belongs to the canceled job, the printer discards the data until the job ends or is stopped. Once the cancellation processing is complete, the printer begins processing the next print job.
