Abstract
A printing apparatus which is capable of preventing printing from being performed on a sheet different from a sheet originally intended for printing, after completion of cleaning. The printing apparatus has a fixing device for fixing an image recorded on a sheet fed from a sheet feeder. The printing apparatus feeds a sheet from the sheet feeder and performs cleaning of the fixing device using the fed sheet. After execution of the cleaning of the fixing device, the printing apparatus requests a user to set a sheet to be used for a page to be printed next, in the sheet feeder.
Claims17
A printing apparatus having a fixing device for fixing an image recorded on a sheet fed from a sheet holding unit, comprising:
- a control unit configured to control to feed a sheet from the sheet holding unit and execute cleaning of the fixing device using the fed sheet;
- and
- a prompting unit configured to prompt, in accordance with completion of execution of the cleaning of the fixing device by said control unit, a user to set a sheet to be used for printing after execution of the cleaning of the fixing device, in the sheet holding unit.
A printing apparatus having a fixing device for fixing an image recorded based on image data on a sheet fed from a sheet holding unit, comprising:
- a control unit configured to control to feed a sheet from the sheet holding unit and execute cleaning of the fixing device using the fed sheet;
- and
- a suspension unit configured to control, in accordance with completion of execution of the cleaning of the fixing device by said control unit, such that printing is disabled until a user instruction is received, even if there is image data to be printed.
A printing apparatus having a fixing device for fixing an image recorded on a sheet fed from a sheet holding unit, comprising:
- a prompting unit configured to prompt a user to execute cleaning of the fixing device, in a case where a number of sheets printed by the printing apparatus has reached a first predetermined sheet count;
- a receiving unit configured to receive from the user an instruction as to whether or not to execute the cleaning of the fixing device as a response to the prompt from said prompting unit;
- and
- a control unit configured to permit to continue printing without receiving the instruction by the receiving unit until the number of sheets printed by the printing apparatus has reached a second predetermined sheet count which is greater than the first predetermined sheet count and then restrict printing in a case where the number of sheets printed by the printing apparatus has reached the second predetermined sheet count without executing the cleaning.
A method of controlling a printing apparatus having a fixing device for fixing an image recorded on a sheet fed from a sheet holding unit, comprising:
- controlling to feed a sheet from the sheet holding unit and execute cleaning of the fixing device using the fed sheet;
- and
- prompting, after execution of the cleaning of the fixing device, a user to set a sheet to be used for printing after execution of the cleaning of the fixing device, in the sheet holding unit.
A method of controlling a printing apparatus having a fixing device for fixing an image recorded based on image data on a sheet fed from a sheet holding unit, comprising:
- controlling to feed a sheet from the sheet holding unit and execute cleaning of the fixing device using the fed sheet;
- and
- controlling, after execution of the cleaning of the fixing device, such that printing is disabled until a user instruction is received, even if there is image data to be printed.
A method of controlling a printing apparatus having a fixing device for fixing an image recorded on a sheet fed from a sheet holding unit, comprising:
- requesting a user to execute cleaning of the fixing device, in a case where a first condition is satisfied;
- receiving from the user an instruction as to whether or not to execute the cleaning of the fixing device according to the request;
- and
- restricting printing, in a case where an instruction not to execute the cleaning is received from the user and a second condition is satisfied without executing the cleaning.
A non-transitory computer-readable storage medium storing a computer-executable program for causing a computer to execute a method of controlling a printing apparatus having a fixing device for fixing an image recorded on a sheet fed from a sheet holding unit,
- wherein the method comprises:
- controlling to feed a sheet from the sheet holding unit and execute cleaning of the fixing device using the fed sheet;
- and
- requesting, after execution of the cleaning of the fixing device, a user to set a sheet to be used for printing after execution of the cleaning of the fixing device, in the sheet holding unit.
A non-transitory computer-readable storage medium storing a computer-executable program for causing a computer to execute a method of controlling a printing apparatus having a fixing device for fixing an image recorded based on image data on a sheet fed from a sheet holding unit,
- wherein the method comprises:
- controlling to feed a sheet from the sheet holding unit and execute cleaning of the fixing device using the fed sheet;
- and
- controlling, after execution of the cleaning of the fixing device, such that printing is disabled until a user instruction is received, even if there is image data to be printed.
A non-transitory computer-readable storage medium storing a computer-executable program for causing a computer to execute a method of controlling a printing apparatus having a fixing device for fixing an image recorded on a sheet fed from a sheet holding unit,
- wherein the method comprises:
- prompting a user to execute cleaning of the fixing device, when a first condition is satisfied;
- receiving from the user an instruction as to whether or not to execute the cleaning of the fixing device according to the request;
- and
- restricting printing, in a case where an instruction not to execute the cleaning is received from the user and a second condition is satisfied without executing the cleaning.
