Event code 71.02.4A HP OfficeJet Pro 8025

[SuzieQQQ1]

I've followed instructions found on this site with no luck, I can manage to get it to a point where I can print a couple of pages but the next time I go to print (usually 24hrs later) it comes back with the same issue, I've done the plug and unplug with and without cartridges and such as suggested. Today before it crapped out again it wasn't recognizing there was paper in the paper tray, when it was full. Any suggestions much appreciated!!!

@SuzieQQQ1, Welcome to HP Support Community,

Thank you for posting your query; I’m here to help by guiding you through steps to resolve this issue

I understand that you are getting a carriage jam issue on the printer, and it shows Event code: 71.02.4A, I am glad to assist you in fixing this issue.

Check for obstructions in the carriage path to make sure the carriage path is not blocked.

• With the printer on, disconnect the power cord from the rear of the printer.
• If your printer has a battery, remove the battery.
• Open the door to access the carriage inside of the printer.

Examples of carriage access doors

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

Example of a printer with debris in the carriage path

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

• 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.
• Close the carriage access door.
• Reconnect the power cord to the rear of the printer, and then turn the printer on.

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.
• With the printer turned on, disconnect the power cord from the printer.
• Unplug the power cord from the power source.
• Wait 60 seconds.
• Reconnect the power cord to a wall outlet and to the printer.
