To fix error code 0XDB0436BC (KERNEL_EXEC_ST) on your HP Envy 5055, perform a hard power reset and clear out residual electrical charge.[ref_1, ref_2]

Step 1: Perform a Hard Reset

• Leave the printer turned on.

• Unplug the power cord directly from the rear of the printer.

• Unplug the power cord from the wall outlet.

• Disconnect any USB or LAN cables attached to the printer.

• Wait for 2 to 3 minutes.

• Press and hold the printer's Power button for about 30 seconds to drain all remaining power.

• Plug the power cord straight into a wall outlet (bypass any surge protectors or extension cords), then plug the other end back into the printer.

• Turn on the printer and wait for it to finish its warm-up cycle.[ref_1, ref_2]

Step 2: Turn Off IPv6 (If the Error Persists)

Network communication glitches can trigger kernel or firmware execution stalls on the HP Envy 5055:

• On the printer's front control panel home screen, swipe or go to Network Setup or Settings.

• Select Network Settings > Advanced Settings > IPv6.

• Turn IPv6 off.[ref_1, ref_2]

Step 3: Check Carriage Path & Firmware

• Open the ink cartridge access door and verify there are no paper jams, dust, or physical obstructions in the carriage path.

• Gently slide the cartridge carriage left and right to make sure it moves smoothly.

• Update your printer firmware via the official HP Support Center to patch background process hangs.[ref_1, ref_2]
