Stick something under the left white hook actually worked for me because there wasn't a spring there to get in the way. The two hooks are connected by a rod so they will both get elevated and the right hook will actuate the microswitch when the cover is closed.

Open the cover an look at the top of the cover.
You will see 2 white hooks. The right one is connected to the opening button of the cover. This hook pushes a mikro switch, when the cover is closed.

So the problem is not, that the cover is not closed tight enough, but that the opening button and the hook to not snap back into there "closed" position, when closing the cover.

Knowing that, close the cover again and just help your opening button a bit, going back to its proper position. That solved the problem for me perfectly.

If it does not solve your problem, add some plastic on top of the hook, as written in the first Solution.

Regards, Michael

How to replace head catridges.


Instructions
  1. Make sure the printer is on, or press the "Power" button to turn it on. Wait for the printer to finish any warm-up diagnostics or print jobs it is performing.
  2. Open the access cover to the print heads. This cover may be the top cover, the front door or an ink access door on the front of the printer.
  3. Wait for the cartridge carriage to stop moving, making sure it is completely stationary before putting your hand in the printer. Lift up any clips or latches keeping the print heads or cartridges in place.
  4. Remove the old print head or ink cartridge if it is part of the cartridge, and discard it. Remove the packaging from the new print head, making sure to peel off any protective tape or twist-off protective caps.
  5. Insert the new print head or cartridge into the empty slot. Lower any clips or latches and make sure the print head or cartridge does not wiggle in its spot, otherwise you need to pull it out and reinsert it into the printer.
  6. Close the cover you opened to access the print heads and wait for the printer to calibrate the new print heads. Some printers may produce an alignment page, which you can throw away.

  2. If you are installing new ink cartridges, remove the sticker and transparent tape from the back and bottom of each ink cartridge.


NOTE: You can use your printer with one cartridge (color or black) at a time. To extend the life of your color cartridge and improve printing speed, install both a color cartridge and a black cartridge at the same time.
  1. Insert the new ink cartridges. Make sure the color ink cartridge is secure in the left ink cartridge carrier and the black ink cartridge is secure in the right ink cartridge carrier.

  1. Snap each lid closed.

  1. Click Next.

Getting "inner cover is open" message


The inner cover is a flap on the inside in front of the carriage when it is at rest when the cover us open. You had to flip the inner cover down to access the ink cartridges.
Open the cover. The inner cover is in the center and need to be flipped up.
Good luck.

B door open


There are two switches, so if you changed the one that was working....

Possible parts affected could be
- cover top
- cover fuser
- cover front assembly
- the switch
1) check the condition of the cover - top, front assembly and cover fuser closed?
2) on the cover top there is an "actuator", a plastic bit, which presses down on the switch assembly top - is that plastic bit broken, bent or deformed?
3) on the cover front assembly there is also an "actuator", check this
4) and of course same for the fuser cover
5) top cover, check the switch, disconnect the switch (P116-1) and press/release it - does that make a difference. If not replace switch
6) same procedure with the switch (P115-1) for front cover.
