Abstract

An image forming apparatus which prevents degradation of sheets stacked in a stacking unit. A sheet feeding unit has a first stacking unit and a second stacking unit. When sheets stacked in the first stacking unit have run out, sheets stacked in the second stacking unit are moved to the first stacking unit. A remaining amount of sheets in the sheet feeding unit is indicated on a display unit. When sheets are stacked in the second stacking unit, the display unit provides an indication that a remaining amount of sheets in the sheet feeding unit is the largest.

First claim

What is claimed is:

1 . An image forming apparatus with a sheet feeding unit that has a first stacking unit and a second stacking unit, comprising:
a moving unit configured to, when sheets stacked in the first stacking unit have run out, move sheets stacked in the second stacking unit to the first stacking unit; and a display unit configured to provide an indication of a remaining amount of sheets in the sheet feeding unit; wherein in response to sheets being stacked in the second stacking unit, said display unit provides an indication that a remaining amount of sheets in the sheet feeding unit is the largest.

2 . The image forming apparatus according to claim 1 , wherein even while said moving unit is moving sheets, said display unit provides an indication that a remaining amount of sheets in the sheet feeding unit is the largest.

3 . The image forming apparatus according to claim 1 , wherein even when no sheets are stacked in the second stacking unit, and a remaining amount of sheets in the first stacking unit is the largest, said display unit provides an indication that a remaining amount of sheets in the sheet feeding unit is the largest.

4 . The image forming apparatus according to claim 1 , wherein when no sheets are stacked in the second stacking unit, and a remaining amount of sheets in the first stacking unit is the largest, said display unit provides an indication that a remaining amount of sheets in the sheet feeding unit is not the largest.

5 . The image forming apparatus according to claim 1 , further comprising a setting unit configured to set a mode that relates to display of a remaining amount of sheets,
wherein when a first mode is set by said setting unit, said display unit provides indications varying with remaining amounts of sheets in the second stacking unit, and when a second mode is set by said setting unit, said display unit provides an indication that a remaining amount of sheets in the sheet feeding unit is the largest in response to sheets being stacked in the second stacking unit.

6 . The image forming apparatus according to claim 5 , wherein when the first mode is set, said display unit provides an indication based on a result obtained by totaling a remaining amount of sheets in the first stacking unit and a remaining amount of sheets in the second stacking unit.

7 . A control method for an image forming apparatus with a sheet feeding unit that has a first stacking unit and a second stacking unit, comprising:
a moving step of, when sheets stacked in the first stacking unit have run out, moving sheets stacked in the second stacking unit to the first stacking unit; and a display step of providing an indication of a remaining amount of sheets in the sheet feeding unit; wherein in response to sheets being stacked in the second stacking unit, the display step provides an indication that a remaining amount of sheets in the sheet feeding unit is the largest.

8 . A non-transitory computer-readable storage medium storing a program for causing a computer to execute a control method for an image forming apparatus with a sheet feeding unit that has a first stacking unit and a second stacking unit, the control method for the image forming apparatus comprising:
a moving step of, when sheets stacked in the first stacking unit have run out, moving sheets stacked in the second stacking unit to the first stacking unit; and a display step of providing an indication of a remaining amount of sheets in the sheet feeding unit; wherein in response to sheets being stacked in the second stacking unit, the display step provides an indication that a remaining amount of sheets in the sheet feeding unit is the largest.
