printer not fuctioning

[Lialp]

my printer is stuck on the startup screen and will not connect to wifi or my computer (via usb cable). Cant be found by online fix apps, Think I need to download new firmware, but the instructions i found require you to access start up screen to do this, which i can't do. 

Is my printer just dead and needs replacement?

Hi @Lialp 

Welcome to the HP Support Community! We're here to help you get back up and running.

I understand how discouraging it feels when your printer stays stuck on the startup screen and won’t connect, even after trying to reinstall apps and cables. 

Thank you for already checking connections and attempting to update firmware—that shows real persistence. Let’s go through a few steps that can help bring the HP ENVY Photo 7855 back to life:

Power reset

• With the printer powered on, disconnect the power cord from the rear of the printer.
• Unplug the cord from the wall outlet.
• Wait at least 60 seconds.
• Plug the cord directly into a wall outlet (avoid surge protectors) and reconnect to the printer.
• Turn the printer back on and check if the startup completes.

Check for stuck hardware initialization

• Remove all ink cartridges and restart the printer without them.
• If the printer passes the startup screen, reinsert cartridges one by one.
• This helps confirm if the issue is linked to cartridge recognition.

Firmware update via USB without control panel

• Connect the printer to your Windows 11 computer using a USB cable.
• Download the latest firmware update utility for your model from HP’s support page:
  https://support.hp.com/in-en/drivers/hp-envy-photo-7800-all-in-one-printer-series/9073044
• Run the utility—it can push firmware directly to the printer even if the control panel is not accessible.

Check for paper or mechanical jams

• Open all access doors and ensure no paper fragments or obstructions are inside.
• A jam can sometimes prevent the printer from completing its startup cycle.

Minimal setup test

• Disconnect all cables except power.
• Remove any memory cards or USB drives from the printer.
• Restart and see if the printer moves past the startup screen.

If the printer still remains frozen after these steps, it indicates a deeper hardware or firmware fault. At that point, you’ve already done the right troubleshooting, and the decision would be whether to continue with service or replacement.
