Reset my HP printer without using the touchscreen

[michelle60523]

i have a HP Emvy Photo 7855 printer that the touch screen has not worked in years.  I use the HP smart app all the time and its worked great until now.  i switched internet providers and now i cannot reset to factory without using the touchscreen on the actual printer.  Is there anyway to communicate with the printer via computer or iphone to change the wifi.

i went with a new internet provider to save money, this will suck if i have to buy a new printer when this one works great using the HP Smart App on my phone

Hi @michelle60523,

Welcome to the HP Support Community

I understand you are facing an issue with your wifi issues HP ENVY Photo 7855 All-In-One Printer. Not to worry I will help you to get a resolution to resolve the issue.

To assist you better:

• How far is the printer located from the WiFi router?
• Do you have a dual-band router?
• If you have a dual-band router and both 2.4GHz and 5GHz networks share the same name/SSID, the printer will not be able to connect to the network. In this case, contact your Internet service provider to assign different names to both networks.

While you respond to that, Let's perform a power drain: 

• With the printer turned on, disconnect the power cord from the rear of the printer and also unplug the power cord from the wall outlet.
• Remove USB cable, if present.
• Wait for 2-3 minutes, press and hold the power button on your printer for about 30 seconds to remove any additional charge.
• Now plug back the power cable straight to a wall outlet without any surge protector or an extension cord (This is important) and then plug back the power cord to the printer.
• Turn on the printer and wait till warm-up period finishes and the printer is idle
