Printer won't close

I understand that your WF 7620 can't recognize your ink, here's a tutorial which might help with this:
Solved Epson printer doesnt recognize Ink Cartridge

try to fix the cartridge or ink properly, it could be that the cable is fasten.

There are a couple reasons a pen refill won't start writing right away. The first thing to check is the tip--often there is a bit of glue or plastic over it in order to prevent leaking.
If that doesn't work, then try one (or both) of the following two methods:
1) Place the refill (but not the tip) in some warm water. Heat will allow the liquid in the gel pen to become thinner and flow more naturally.
2) Hook a rubber band around the middle of the pen, using tape to ensure safety, and wind the pen while holding the rubber band on either side of the pen. Make sure the cap is on the pen. When the rubber band is tight, when you pull straight out on the rubber band from both sides of the pen, it should spin very quickly. The centripetal force will cause the liquid in the pen (at least half of it) to move toward the tip.
Make sure you fasten the rubber band to the pen with tape or something similar; otherwise the pen may go flying off at someone nearby. Also, again, make sure the cap is on to prevent any ink spraying out--this is unlikely in a gel pen, but it could happen.

Hi Good day!!! try this trick ^_^ open the cover of your printer to see the print head, now turn off your printer you will see your print head is moving when it moves to the center pull out the power cord of your printer ( this trick is about good timing) if success the print head is now in the center now remove the ink cartridge (note don't installed the new cartridge yet) now turn back on you printer without the cartridges, your printer will recognize that the cartridges are missing, ^_^ and finally your printer will find the your inks after that insert it according to its location.

The cause is either:
* clogged ink-jets not allowing yellow & blue ink to move from the ink-cartridge onto the paper;
* busted electronics inside the printer, causing the ink-jets to not "spray" at all.

Use the software to try a "print-head-cleaning" cycle.
If that fails to improve things, it's time to replace the printer.

Since the problem changed when you did the ink cart replacement, is it possible that you neglected to do something --- normally all you do on installation is to remove the tape present to protect the pins on the cart; other than that, there is not much to be done. If the same thing happens with multiple catrtidges make sure you are using the correct cartridges, and that the cartridges are properly fastened down, hard not to if it clicks it is in right. Procedures say to do an alignment after replacement and that is done automatically. Prescence or lack of printing is only a factor of ink being in the cartridge.

yes you can repair it from vendor.

Hi there. Insert the mesh strap inside the hole and secure with the hook and clip fastening with a foldover security clasp.

Hope this one helps.

The part has been broken in my printer for over a year now. I hold the cartridge in with a rubber band.

Hello trollmor:

These are great questions. The mosquito net elastic loops are going to be fastened around the hooks under the canopy. In order for it to work properly, the elastic hooks that hold the canopy in place need to be removed and the elastic loops for the mosquito net and sun shade will take their place. The elastic should hold both shades in place properly.

If this does not work, please feel free to email me at strollerinfo@gmail.com.
