mx920 document in ADF

[Teresinha]

Hello, my scanner is not working : there is always a message indicating "document in ADF", "press OK". 

The printer works fine though.

If the printer "thinks" there is a document insert into the ADF, then one of the following is probably true:

Door isn't closed

Sensor is dirty or failing

Physical debris or paper present

This is a mechanical error.

Thanks - but the message only comes after page 1 or 2...

Hi,

Big difference between " there is always a message indicating "document in ADF"

and

but the message only comes after page 1 or 2...

inspect and check the ADF for foreign debris, worn rollers or feeders, binding, any old remnant pieces of torn paper.  Best way to clean is with canned air and a Q-Tip dipped in alcohol.  Some of the grears / components might have a light coating of white lithium grease.  If in doubt, don't apply unless you are absolutely sure.

The paper width must also be set evenly and straight.  First page feeds, send can jam if not aligned correctly.  Also suggest you fan the paper before inserting and adhere to the max number of sheets the ADF can be loaded with.
