@bicidedida Welcome to HP Community!

I understand that you are getting printer failure and error code:  71.02.4B.

Do not worry. I will try to fix the issue.

Reset the printer

1. Turn the printer on, if it is not already on.

2. Wait until the printer is idle and silent before you continue.

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

4. Unplug the power cord from the wall outlet.

5. Wait at least 60 seconds.

6. Plug the power cord back into the wall outlet.

   NOTE: 

   HP recommends connecting the printer power cord directly to the wall outlet.

7. Reconnect the power cord to the rear of the printer.

8. Turn on the printer, if it does not automatically turn on.

9. Wait until the printer is idle and silent before you proceed.

Unseat the printhead

1. Open the front door, and then lift the ink cartridge access door.

   The carriage moves to the center of the printer.

   

2. Wait until the carriage stops moving before you continue.

3. Unplug the power cord from the rear of the printer. Unplugging the printer prevents the carriage from moving.

      WARNING: 

   You must disconnect the power cord before reaching inside the printer to avoid risk of injuries or electric shock.

4. Lift the carriage latch.

   

5. Grasp the sides of the printhead, and then slightly lift the printhead without fully removing it from the carriage.

   

Reseat the printhead, and then lower the carriage latch

1. Reinsert the printhead into the carriage to reseat it. As you guide the printhead into the carriage, it settles into the carriage as it seats.

   

2. Gently rock the printhead to the left and right to make sure the printhead fully seats in the carriage.

3. Lower the carriage latch.

   

4. Make sure the carriage latch is down.

5. 1. 

      Carriage latch is up

   2. Carriage latch is down

6. Close the front door and ink cartridge access door.

   

7. Reconnect the power cord to the rear of the printer.

8. If the printer does not turn on by itself, press the Power button to turn it on.

9. Wait until the warm-up period finishes and your printer is idle and silent before you proceed.

The instructions for this error code don't work for the 8035. The 8035 doesn't have a carriage latch. When the error code is on the screen, the carriage won't center when the door is opened.
