The Power light blinks at a steady interval when the printer is processing a print job. If the Power light blinks fast, the ink cartridge door might be open, or the printer might be in an error state.
Are you wondering why my printer is showing orange light? It indicates firmware issues, paper jams, or improperly installed cartridges. Resolve it by performing a power reset of your printer.

This occurs when the printer loses the Wi-Fi connection or there is a connection error during setup. If this happens during first-time setup, press and hold the Wireless button on the back of the printer for five seconds to reset the wireless connection.

The power light is on or flashing. The ink light is flashing. Ink in a cartridge is low. You can continue printing, or check which cartridge is low and replace it.

The Wireless light blinks when the printer is attempting to connect to the wireless router or access point. Wait a few minutes, and then check the light again. If the Wireless light is on and steady, the printer is connected and you can stop troubleshooting.
You can run a power ink flushing to replace all of the ink in the ink tubes if necessary. This may improve print quality, but consumes more ink than the head cleaning or powerful cleaning options. This process can take up to 20 minutes.
The Status light stays yellow and on steady (not flashing) normally to indicate that there is data remaining in the printer`s memory. Press the GO button once to print the remaining data in memory.

HP deskjet 460 Waste ink tank full
ANSWER : I worked fixing printers for 5 years for Verizon and some of the older printers were notorious for the waste receptacle filling and overflowing with ink. My solution was good old warm water. Remove the waste container and scoop out as much as you can with a small screwdriver, wiping the discard on a paper towel, then just run warm water from the faucet into the container till all the residue is removed. This is just water soluble ink folks, if you want to test it, scoop out a glob and dissolve it in warm water, its easy as pie. I never once bought a new ink discard reservoir. I just cleaned out my mobile 460 printer reservoir by the same method. There are no electrical connections its just all plastic.
