    Sharp MXC402SC error code L3-00

    A customer that moved here (Houston) from California brought a Sharp MXC402SC with them. This is in the customers home. I went out there Monday (3/14). The machine didn't look like it was properly prepared for the move.

    As I examined it I noticed that many of the places where the screws holes in the covers were broken. There was also a lot of cyan all over the vents in the back. When I arrived the machine was giving a L3-00 code.

    I managed to get into the scanner area and the rail seemed to rather dirty. I cleaned the rail off wit a light lubricant. My rag came away a little blue as I cleaned the rail. After I put the machine back together, it started working fine. We made many copies and scans without problem before I left.

    Yesterday afternoon the customer called saying the machine is giving the error code of L3-00. They can reboot, but it comes back.

    Any insight into this problem with this machine would be helpful. All silver bullets are welcomed.

    Thanks.

    Hi

    L3-00 is scanner return trouble

    Please check the sensors for the scanner. I once had this error on a ship that got into rough seas.

      If the rail was dirty then the home position sensor probably is as well. If you didn't clean this that might be the problem. Also check the white rollers that the scanner wires run on the bearings go bad occasionally. Sensor might of got knocked out of position also.

      good luck

        Are they putting a book on the glass?

        Most people will pull down on the document feeder lid to press the book down and that will cause the glass to flex and give you this code.

        Tell them not to push down on the document feeder and not to put a very heavy book on the glass.

          For all these B/C models with this problem, fixed as such:
          access scanner rail, remove rail from scan optics, clean with alcohol, flip rail over so it runs on untracked steel.
          SLIGHTLY stretch belt tension spring, re-assemble. Use alcohol on rail surface and run scanner back and forth many times (slowly), cleaning each time until all dirt residue is gone. Apply light coating of fuser oil (may need to thin w/alcohol), run it back and forth many times (slowly) until smooth.
          It's never been the sensor for me.
