    Hi Vinay

    The card reader may be separated from the UM2 housing. There are two screws for sheet metal cover on the printer bottom. Sometimes this cover is a little hard to remove, but with a little patience and feel it's ok. The board of the card reader should now be accessible. The rotary knob is pushed onto the rotary switch, so it must be carefully removed from the back so I can see it on the basis of existing Images.

    So you can see what is behind the sheet metal cover,

    Here is a LINK: http://www.aliexpress.com/store/product/3-D-printer-parts-Ultimaker-2-ulticontroller-rev-2-1-display-kit-DIY/115344_2054686166.html

    This sheet cover I mean:

    UM2 OLED SheetMetalCover

    And here you can see it (highlighted in yellow) without UM2 front:

    UM2 WithoutFrontCover

    The two tongues keep the OLED display in Position.


    For an attempt to repair the card reader, you have (probably) remove the small cover plate so that the contacts mechanism is accessible. But maybe your UM2 is covered by warranty, contact the Ultimaker support first. Otherwise, you can (for example) the complete OLED unit bought from Aliexpress.

    I had the same problem and the reply of mnis, Markus proved very useful. However, the problem proved to be a small string of filament which was in the back of SD-card holder. I was able to remove this with a needle.

    So in the end I wouldnt have needed to open up my machine. Would be a good thing to check if you ever find yourself in a similar situation.
