How to solve message "scanner unit is open" or "close the scanner unit" on Epson printers




Solution 1:
  • Power off the printer
  • Unplug the power cord and wait 5 minutes
  • Plug back et power on

Solution 2: When you close the scanner assembly it pushes a small lever that say the scanner is closed. But sometimes, this lever is not pushed far enough, or is defective. Try this:
  • Close the scanner unit and slammed it slightly.
  • If it does not work, try to push the lever with a pencil

I have an Epson WF-7610 that kept prompting this error message
whenever it requires ink cartridges to be changed. It says:
“Scanner unit is not closed”

Can someone please post a photo of where the lever is???

I found it. You need to open it up like you are going to change the ink cartridges. this means you need to lift both top levels. Then you will see the lever on the base portion (bottom part) of the device. If you press down the lever, it will start to print and you will see the ink cartridges go back and forth. Keep your fingers clear. :)

After hours of Googling and trying :

On an Epson WF-7620, open the printer lid as if you were to replace ink. The system will say 'Close the scanner unit'.

With a toothpick, push down the little lever located in a small slot on the inside rim of the unit, close to the power button.

Using the touch screen panel, follow the normal procedure to change the cartridges, while keeping the lever down for the first bit.

Good luck!

Jonas -- Yes this is the solution! I needed to use a bright flashlight to see exactly where the thin lever is and position the toothpick horizontally in the slot, keeping my hand out of the way of the mad back and forth passes of the print head.

My question now is, during printhead align I see there are 5 pattern choices (1-7) to select in order to choose the best solid looking square in each pattern, shown in the printhead test printout. Problem is, my 840 workforce only printed out three patterns of black/gray squares represented by Xs below. Don't know how to evaluate this.???

X X XX X X X
X X XX X X X
X X XX X X X

I will Google this now, but if you know the answer, please let me know -- thanks!

Update: I bypassed the above problem by using the Epson web site instead of the printer control panel. The subsequent printout makes sense and is more thorough. Another Epson SNAFU wasting everyone's time!!!

Solution 1:
Look inside for a tiny object like a piece of paper, a staple...
Solution 2:
The purge cap (the white sliding mechanism that the print head parks to when it's not in use) may be not lubricated well enough . Lubricate the sliders with some white grease (don't get it on the small wipers or the black caps); this repair probably require to remove the right panel off of the printer to gain access to the purge mechanism.
Solution 3: Clean the timing strip: there is a thin plastic strip running across the width in front of and below the drive belt: there are f…
