8710

Hi,

 

My HP8710 has started randomly locking up with the message below, re-booting cures the issue. There is no other info apart from Event code 74740 in the log.

A new message, phone cord connected has now started popping up during a scan operation. No cord is connected.

 

I would usually do a factory reset at this stage but the printer is on Instant Ink and I get a warning 'Instant ink will no longer function after the reset'

 

Any ideas?

 

Cheers.

Hi @M1711,

 

I'd like to help!

 

I understand you are receiving a 740740 error on the printer screen.

 

Try the below suggestions-

 

Let's try a power reset on the printer

 

Reset the product

  • With the printer turned on, disconnect the power cord from the rear of the printer.
  • Unplug the power cord from the wall outlet.
  • Wait at least 60 seconds.
  • Plug the power cord back into the wall outlet.
  • Reconnect the power cord to the printer.
  • Turn the printer on. HP recommends plugging the printer directly into a wall outlet.

 Also, try updating the printer's firmware - HP Printers - Updating or Upgrading Printer Firmware

 

Hope this helps! Keep me posted.
