Printing system, static elimination apparatus, method for controlling printing system, and storage medium

A printing system comprising:

• a printing apparatus configured to execute a printing process on a sheet;
• and
• a static elimination apparatus configured to perform a static elimination process on the sheet printed by the printing apparatus,
• wherein the static elimination apparatus includes a first static elimination unit provided on an upper surface side of the sheet printed by the printing apparatus, and a second static elimination unit provided on a lower surface side of the sheet, the static elimination apparatus being configured to switch the first static elimination unit to on or off, and configured to switch the second static elimination unit to on or off, and
• wherein the static elimination apparatus includes a control unit configured to perform control to, depending on whether the sheet printed by the printing apparatus has been subjected to one-sided printing or two-sided printing and whether a surface of the sheet last printed is on a first static elimination unit side or a second static elimination unit side in a case where the sheet passes through the static elimination apparatus, switch the first static elimination unit to on or off and switch the second static elimination unit to on or off.

A static elimination apparatus connected to a printing apparatus configured to execute a printing process on a sheet, the static elimination apparatus configured to perform a static elimination process on the sheet printed by the printing apparatus, the static elimination apparatus comprising:

• a first static elimination unit provided on an upper surface side of the sheet printed by the printing apparatus, wherein a polarity of a voltage to be applied to the first static elimination unit is switched to positive or negative;
• a second static elimination unit provided on a lower surface side of the sheet, wherein a polarity of a voltage to be applied to the second static elimination unit is switched to positive or negative;
• and
• a control unit configured to perform control to, depending on a printing surface of the sheet printed by the printing apparatus, switch the polarity of the voltage to be applied to the first static elimination unit to positive or negative and switch the polarity of the voltage to be applied to the second static elimination unit to positive or negative.
