Patent number: 11516356Abstract: In a normal mode that is a mode when a user performs a printing work, a wireless operation unit shifts to a second mode when the wireless operation unit is not operated for a first predetermined time in a first mode. In a maintenance mode when a repairman performs a maintenance work, the wireless operation unit does not shift to the second mode even if the wireless operation unit is not operated for the first predetermined time in the first mode. In addition, in the maintenance mode, if the remaining amount of a battery is equal to or greater than a predetermined amount in the first mode, the wireless operation unit does not shift to the second mode, and if the remaining amount of the battery is less than the predetermined amount, the wireless operation unit shifts to the second mode.Type: GrantFiled: February 22, 2022Date of Patent: November 29, 2022Assignee: CANON KABUSHIKI KAISHAInventor: Shozo Yamasaki
