Inkjet fax machine SF-340 (SF-341P) to send fax and copy out the paper on both sides of the black road, how to solve

Example:There are black lines on both sides of the paper that are sent and copied, but it is normal to print the test page.

 

 

Original cause:The document scanner is dirty and needs to be cleaned.

 

The solution is as follows:

 

I. Clean white rollers

 

1. Shut down the machine and open the control panel.

 

2. Remove the white roll (the right side of the white roll has a bushing fixed with a small tongue, gently push the tongue into it, then turn it to you, pull out the right part to remove it ).

 

 

 

3. Use a soft cloth or cotton swab to wipe the white roll surface.

 

  

 

4. Clean the ADF rubber components behind the control panel.

 

II. Cleaning and scanning glass plate

 

1. Scan the glass plate carefully with a dry cloth. (If the glass plate is dirty, first wipe it with a soft cloth containing water, and then wipe it with a dry soft cloth .)

 

 

 

After completing the preceding operations, reinstall the white roll, close the control panel, and then start the machine to restore normal.
