What should I do if the scanner cannot return to the original position?

Scanners are peripheral components that are often used in computers. For example, if the scanner cannot return to the original position, it is a common fault. So what are the reasons why the scanner can't return to its original position? Let's see what happens when the scanner can't return to its original position:

First of all, let's see what causes the scanner not to return to its original position.

First, the scanner's return sensor performance is poor, causing the scanner to not return to its original position.

Second, poor scanner performance of the scanner can prevent the scanner from returning to its original position.

Third, the scanner's return sensor controller is in poor contact, causing the scanner to not return to its original position.

Fourth, there is a fault in the mechanical aspect of the scanner's drive system that causes the scanner to fail to return to its original position.

solution:

First we can turn on the printer, push the scanner back to its original position, and then turn it on to see if the panel is normal. If the scanner is not in place, it should return to its original position immediately.

Then we can turn on the printer and move the scanner back and forth by hand to see if all the chains can follow.
