Disassembly Instructions

Now that you have the replacement shafts, it’s time to take apart your scanner!  It’s pretty easy to do.

Before you begin

  • Have the replacement shafts on hand
  • Make sure your scanner is unplugged!
  • Remove the bottom tray
  • A towel or a work surface that won’t lead to any scratches
  • You’ll need these tools:
    • Phillips screw driver
    • Flat head screw driver or a small pry tool
    • Needle nose pliers

Step 1

Pop open the front cover.  Move the paper adjustments inward and pop open the middle cover.  Remove the top roller.  Now remove the 3 screws.

 

Step 2

Turn the scanner over and remove the 3 screws that were previously covered up by the paper tray.

 

Step 3

Pry away the outer cover.  There’s indentations along the left and right sides.  Insert your flat head screw driver here and twist it gently.  This will separate the outer cover from the scanner itself.  Carefully pull the cover away.

Step 4

Remove the screws shown in these 2 pictures and then remove the 2 plastic covers that they hold in place.

Step 5

Once the screws and little plastic covers are off, you’ll be able to remove the front cover.  This is accomplished by shifting the cover to the left and then pulling it UP.  There’s a cut out in the right plastic hinge that allows this piece to slide out of place.  Once it’s out, you can then move the cover to the right in order to get the opposite side out.  Be VERY careful not to damage the wires that are routed along this side!

Step 6

With the front cover off, you can remove the 4 screws.  Pop open the gray piece in the middle and remove the roller.

Step 7

Pry away the outer cover by inserting your flat head screwdriver into the indentations along the left and right sides.  Gently twist it to separate the outer cover.  You might also need to pry it apart at the small gap that runs along the top and bottom of the cover.

Step 8

With the front cover off, you can see the broken parts for yourself.  One or both may be broken.  They don’t usually break off completely – just splay apart as my picture shows.  Go ahead and remove the broken shafts.

Step 9 – Read this one carefully!

Please exercise caution when executing this step!  Roughly 5 people have reported that they managed to break the thicker shaft when installing it.  I’ve fixed well over 100 of these scanners without breaking the replacement shaft, so I’m not sure what they’re doing.  If you break yours during installation please contact me for a replacement set at info@epsonscannerrepair.com

Now here’s the fun part.  Carefully disconnect the little connector (blue square in the picture below).  Then move the feed switch to the up (single sheet feed) position.  This will allow you to rotate the shaft that outboard shaft connects to.  Make sure the thin side is pointing towards you.

The shaft with the thicker end goes in first.  You’ll have to angle it into place and then press down on the back (thinner) side.  It’s a tight squeeze due to the thicker end, but rest assured it will go into place.  You may have to use needle nose pliers to get it into position.

Here’s a short video that shows how to get it into place without breaking it:

And a picture of the shaft after installation:

Step 10

With the innermost shaft in place, you can then install the smaller one.  Insert it into the hole and make sure it’s lining up with the other shaft.  Once the shaft ends are lined up, press down on the plastic piece where the roller was located and insert the opposite end into place.

That’s it!  Those last 2 steps might require some patience and perhaps some cursing, but rest assured, everything will fit into place.

Reassembly

Repeat the steps above in reverse.  Make sure to plug in any connectors you may have disconnected.  The connector for the main harness that goes into the board in the front cover may have worked itself loose (I don’t have a picture!), so make sure that it’s firmly in place.  It might look like it’s connected, but it could be loose.
