How to Identify and Fix Common Problems ?

Our sources include academic articles, blog posts, and personal essays from experienced technical support :

Master Reset: Unplug the printer, then pressing the help and ok buttons simultaneously plug it back in.
If your printer is turned on, disconnect the power cord from the printer. Keep the power plug unplugged for 60 seconds, reconnect the power cord to the wall, and turn on the printer. If the error persists, remove the cartridge from the printer, clean the cartridge contacts with a cloth, and reinstall the cartridges.
Answer. On HP printers, a “cold reset” causes the printer to return to its factory default settings, which among other things, causes it to try and retrieve its configuration information from a BOOTP server.
Turn the printer off then back on. If the issue persists, turn the printer off, unplug the power cord and then wait at least three minutes before plugging the power cord back in and turning the printer back on. If the issue persists, ensure the product is running the latest firmware available from HP.com.
Power down the printer and then unplug the power cord from the printer and the wall. Wait for a minute, then plug the printer back in. The printer will reset and turn on.
Make sure the printer is on and connected to your computer. Go to HP Software and Driver Downloads, and then enter your printer model. Select Firmware from the list of drivers, click Download next to the update, and then follow the instructions.
To remove all data from your phone, you can reset your phone to factory settings. Factory resets are also called “formatting” or “hard resets.”
Turn on the laptop and immediately press the F11 key repeatedly until System Recovery starts. On the Choose an option screen, click “Troubleshoot.” Click “Reset this PC.”
