How to Disassemble Epson Expression XP 7100 Printer - Taking it Apart

Today we’re going to disassemble the Epson Expression XP 7100. If you have any questions or want to learn more about a part that’s not clear, or would like us to make a more specific video on that topic, please leave us a comment, and I will see if I can accommodate that. Also, if you feel this article is unclear would like a paper copy of the workflow, you can purchase one here for $1.99.

Step 1: Remove the Paper Trays and Duplexer

We will be finishing that first section in the workflow where we removed the paper tray and the duplexer and then go on to the second section, which involves removing the scanner. Notice that the first set of instructions under the “remove scanner” step says to turn the printer back off. From a top-down view, we find two silver screws (SS). SK is used to refer to a black screw.

Step 2: Remove the Scanner

Remove the screws at the back of the printer to peel off the side panel. Now we can unscrew the first circuit board. By the way, on the right-hand side of your worksheet, you’re going to see the parts number. It will show you which parts you can remove from each procedure. Make sure that all the cables are detached, including the FFC cable.

Take a look from underneath to ensure that everything is detached. Now simply pull the scanner towards you, and it should come off. Also, be sure to take a picture before this so that you know which wire goes where when you go to put it back. If you don’t have a picture, you can go to BCH’s website and download one from there.

Step 3: Remove All Visible Screws

Now we can turn the printer around and release the locks on the printhead. You need to turn the wheel on your left side counterclockwise to do this.

Step 4: Remove the Top Long Plate

You can remove the top long plate from the top and just take it off.

Step 5: Remove the Corner

At this point, you can remove the corner plates. The workflow says to remove the right plate, but you can start with the left if you want. It doesn’t matter.

Step 6: Remove the Other Corner

For this step, simply remove the other corner.

Step 7: Remove the Top Assembly

You can finally remove the front LCD panel.

Step 8: Remove the Waste Tank

We can remove the waste tank at this point. I realize the angle is not great for this waste tank removal, so I will shoot another video to show you how to do it properly.

Step 9: Remove the CSIC Board

Now we can take the printhead and the CSIC board out.

Step 10: Remove the Timing Belt

Remove the timing belt.

Step 11: Save the CR Scale Sensor

After removing the timing belt, make sure that you save the CR sensor. This sensor is mounted on the printhead carriage assembly.

Step 12: Remove the FFC Cable

Next are those FFC cables. Basically, just run them through the loop and take them out.

Step 13: Remove the Pulley

Now we need to remove the pulley. Turn the printer back towards you and just use a screwdriver to remove the bigger spring. The cable on the carriage return will be loose, and you can take the pulley out. You should now be able to remove the drive cable.

Step 14: Remove Printhead Rails

We are now going to remove the printhead rails. There’s an upper rail and a lower rail. Just unscrew all the screws under the rail, and the printhead carriage will come off. Here’s where the ejection sensor is for those of you who have a faulty one. If the sensor is defective, it will show that you have a paper jam even if you don’t have any paper inserted.

Step 15: Remove the Paper Guide

If you want to get to the sensor, you’ll need to remove the paper guide.

Step 16: Remove the Upper Rail

For step 16, you will also need to remove the top part of the rail. Of course, you don’t need to remove the motor if you’re only trying to get to the ejection sensor. However, you don’t really have to go through all this trouble to fix the sensor. I may shoot another video on this topic. You can just install the sensor at another place that has the same function.

Step 17: Remove the Power Supply

You can unwind those wires and remove the power supply and waste pump.

Step 18: Remove the Main Board

Finally, you should remove the main board. I don’t know why Epson designed the main board to be horizontal and under the printer. Typically, Epson designs it another way that is not so vertical, so you don’t have ink dripping on it. This model is very unusual—it’s very hard to get to the main board.

Again, if you get stuck at any point in this process, just leave a comment or shoot us an email, and we’ll see if we can help you out. I hope this article helps you finish your project. Please visit us atbchtechnologies.com, or locally at Greensboro, North Carolina. Cheers!
