Multifunction peripheral and operation method thereof

A multifunction peripheral, comprising:

• a body comprising a first channel, a second channel, a third channel, and a fourth channel, wherein the second channel is connected to the first channel and forms a loop with a part of the first channel, the third channel is connected to the first channel, and the fourth channel is connected to the second channel;
• a first switch disposed at a junction of the third channel and the first channel;
• a second switch disposed at a junction of the second channel and the fourth channel;
• a plurality of first drive roller assemblies respectively disposed on the first channel and the second channel;
• a printing module disposed in the body and on the first channel of the loop;
• a first shredding module disposed in the body and below the first channel and the second channel, wherein the third channel extends from the first channel to the first shredding module, and a first shredding roller of the first shredding module is disposed at an end of the third channel away from the first channel;
• a second shredding module disposed in the body and below the first channel and the second channel, wherein the fourth channel extends from the second channel to the second shredding module, and a second shredding roller of the second shredding module is disposed at an end of the fourth channel away from the second channel;
• and
• a control module electrically connected to the first switch, the second switch, the plurality of first drive roller assemblies, the printing module, the first shredding module, and the second shredding module,
• wherein the control module connects a section one and a section two of the first channel through the first switch and closes the third channel, or connects the section one and the third channel through the first switch and closes the section two,
• the control module connects an upstream of the second channel to the fourth channel through the second switch and closes a downstream of the second channel, or connects the upstream and the downstream of the second channel through the second switch and closes the fourth channel.
