Error Message when installing printheads on new Smart Tank 555 Printer

[Hedgehurst]

I'm unpacking & setting up a new Smart Tank Plus 555 printer, following instructions on "Start Here" leaflet.

All good until I installed the print heads. I removed the sticky tape , also the orange inserts in the nozzles, clicked them into place,  and it's now flashing E3  followed by ! and the image of the printheads.

First time in they didn't click firmly - maybe I'm reluctant to press hard in case of breaking things.  I opened the blue latch & clicked them in place, closed the latch again.

I haven't yet connected to the computer, which runs on Ubuntu 18.04.
I'll be using USB cable because I don't have wireless connection on this computer.

Now I'm stuck for what to do next, & will welcome advice.

Thanks.

Hi @Hedgehurst

Welcome to the HP Support Community. I'd be happy to assist you with the  "carriage jam" issue. 

Try the below-recommended steps to resolve the error-

Step 1: Check for obstructions in the carriage path

Make sure the carriage path is not blocked.

1. With the printer on, disconnect the power cord from the rear of the printer.

2. If your printer has a battery, remove the battery.

3. Open the door to access the carriage inside of the printer.

4. Look in the carriage path for debris such as crumpled paper or dislodged labels, and then remove any that you find.

5. If the carriage on your printer has a latch, make sure it is closed.

      CAUTION: 

   Ink tank printers: If the latch is closed, do not press down on it.

    

   

6. Use your hand to move the carriage to each side, making sure it moves freely. If the carriage is stalled or docked to one side of the printer and you cannot move it, continue with these steps.

7. Close the carriage access door.

8. Reconnect the power cord to the rear of the printer, and then turn the printer on.

If the error persists, continue to the next step.

Step 2: Reset the printer

An error might continue to display after the jam is cleared. To clear the error state, reset the printer, connecting the power cord directly to a wall outlet to make sure the power source is stable and prevent more carriage jams.

1. With the printer turned on, disconnect the power cord from the printer.

2. Unplug the power cord from the power source.

3. Wait 60 seconds.

4. Reconnect the power cord to a wall outlet and to the printer.

   NOTE: 

   HP recommends plugging the printer directly into a wall outlet.
