my printer will not start up. I keep getting ‘b854a3f4 error i have tried unplugging and disconnecting ink carriage with little to no difference hp Officejet pro 8610
Reset the printer:- remove the power cable from the back of the printer while the printer is still powered on and reconnect after a minute
Reseat the printhead:- Unplug the power cord from the rear of the printer. Unplugging the printer prevents the carriage from moving. Open the cartridge access door and reseat the printhead
Reseat the printhead upto three times:- Sometimes error messages persist after inserting the printhead. To clear any error messages, reseat the printhead by repeating up to three times.
Replace the printhead:- If you are still experiencing a problem, replace the printhead.
If the issue still persist, contact tech support for help
