Abstract
An image forming apparatus includes a controller to set one of a first print mode, in which, after starting printing on a first number of sheets per unit time, a printer decreases a number of sheets on which the printer performs printing per unit time from the first number of sheets per unit time so as to avoid a rise in temperature of a fixing device to a predetermined temperature value, and a second print mode. In the second print mode the printer performs printing on a second number of sheets per unit time without changing, based on a rise in temperature of the fixing device, a number of sheets on which the printer performs printing per unit time, where the second number is smaller than the first number.
Claims10
An image forming apparatus comprising:
- a printer that prints an image on a sheet and that includes a fixing device;
- and
- a controller,
- wherein the controller sets one of a first print mode or a second print mode,
- wherein the first print mode is a mode in which, after starting printing on a first number of sheets per unit time, the printer decreases a number of sheets on which the printer performs printing per unit time from the first number of sheets per unit time so as to avoid a rise in temperature of the fixing device to a predetermined temperature value due to continuation of the printing on the first number of sheets per unit time,
- wherein the second print mode is a mode in which the printer performs printing on a second number of sheets per unit time without changing, based on a rise in temperature of the fixing device, a number of sheets on which the printer performs printing per unit time, where the second number is smaller than the first number, and
- wherein the printer prints the image on the sheet based on one of the first print mode or the second print mode set by the controller.
A control method for an image forming apparatus that includes a printer to print an image on a sheet and a fixing device, the method comprising:
- setting one of a first print mode or a second print mode, wherein
- in the first print mode, after starting printing on a first number of sheets per unit time, decreasing a number of sheets on which the printer performs printing per unit time from the first number of sheets per unit time so as to avoid a rise in temperature of the fixing device to a predetermined temperature value due to continuation of the printing on the first number of sheets per unit time, and
- in the second print mode printing on a second number of sheets per unit time without changing, based on a rise in temperature of the fixing device, a number of sheets on which the printer performs printing per unit time, where the second number is smaller than the first number, and
- printing the image on the sheet based on one of the first print mode or the second print mode that is set.
A non-transitory computer-readable storage medium storing a program for causing a computer to execute a control method for an image forming apparatus including a printer that prints an image on a sheet and a fixing device, with the control method comprising;
- setting one of a first print mode or a second print mode, wherein
- in the first print mode, after starting printing on a first number of sheets per unit time, decreasing a number of sheets on which the printer performs printing per unit time from the first number of sheets per unit time so as to avoid a rise in temperature of the fixing device to a predetermined temperature value due to continuation of the printing on the first number of sheets per unit time, and
- in the second print mode printing on a second number of sheets per unit time without changing, based on a rise in temperature of the fixing device, a number of sheets on which the printer performs printing per unit time, where the second number is smaller than the first number, and
- printing the image on the sheet based on one of the first print mode or the second print mode that is set.
