Smart Tank Plus won't start - error code 0XC4EB8004 HW_MICCI2_V12

[RJL15041912]

I've tried resetting the printer by disconnecting power and waiting 60 seconds, but the printer goes through a restart attempt but crashes (after the cartridges move a little) with error code 0XC4EB8004 HW_MICCI2_V12.

Have you any help with what I can try now ?  Thanks

@RJL15041912, Welcome to HP Support Community. 

Thank you for posting your query, I will be glad to help you. 
The 0XC4EB8004 HW_MICCI2_V12 error on the HP Smart Tank Plus 570 usually indicates a hardware failure, often related to the ink system, printhead, or internal electronics. Here are some steps to try:

Power Reset (Deep Reset)

Since you've already done a basic power reset, try a deeper reset:

>Turn off the printer.

>Disconnect the power cable from both the wall and printer.

>Remove all cartridges.

>Hold the Power button for 30 seconds.

>Plug the printer directly into the wall (avoid surge protectors).

>Turn it on without reinstalling the cartridges yet.

>If it starts without the error, reinstall the cartridges one by one.

Check for Paper Jams or Obstructions

>Open the ink access door and remove the cartridges.

>Inspect the printhead area and carriage path for any stuck paper, debris, or ink spills.

>Move the carriage gently left and right to check if it moves freely.

>If you see ink buildup, use a lint-free cloth slightly dampened with distilled water to clean it.

Clean the Encoder Strip

>The encoder strip is a clear plastic strip behind the carriage. If dirty, it can cause errors:

>Turn off the printer.

>Locate the clear strip behind the printhead carriage.

>Gently wipe it with a soft, lint-free cloth dampened with filtered water.

>Let it dry before turning the printer back on.

 Reseat the Printhead

>If your printer has a removable printhead:

>Open the ink door.

>Lift the printhead latch and remove the printhead.

>Clean the contacts with a lint-free cloth.

>Reinstall the printhead, close the latch, and restart the printer.

Update Firmware (If Possible)

>If the printer works intermittently before showing the error:

>Download and install the latest firmware from HP’s website:
HP Support - Software & Drivers
 

Try a Semi-Full Reset (Factory Reset)

>Press and hold the Power button.

>While holding, press the Cancel button 5 times, then Resume button 2 times.

>Release all buttons and wait for the reset process.

I hope this helps. 

Take care and have a good day.
