Printer flashing 7 orange 1 green

LOL… thermometer, and what’s the relation to the printer?
----------------------------------------------------------------------
some info:
-------------------------------
turn off the printer
- hold down the resume button (the one that’s flashing) and press power for a few seconds while still holding down
- release resume then power
- press resume 2 times
- wait a moment then press resume 3 times (the button should turn orange)
- press power then wait
- restart your printer and it should work.
-------------------------------------------------------------------------
delete your printer and reinstall it. in case of orange flashing, press the orange button for 30 seconds and release like for a test print.
---------------------------------
- Unplug the printer - Keep both buttons pressed - plug back in - hold both buttons for more than 10 seconds (at least 1 minute for my part otherwise it didn’t work) - (the light stays orange even once the fingers are removed - Wait a bit and press power - restart the printer and it works!!!
-----------------------------------------------------
to clear the printer's memory and erase permanent errors like "ink recovery reservoir full":

Button 1 = Power on/off
Button 2 = Cancel/Restart

1. Start with the printer off (all lights off)
2. Press 2 then 1 while keeping 2 pressed
3. Keep 1 and release 2
4. Keep 1 then 2 quick presses on 2 > the light turns orange then green
5. Release 1 and wait for the light to stabilize on green
6. 3 quick presses on 2 > the light turns orange, then green, then orange
7. press 1

Memory is cleared and permanent errors are gone. you will need to reprogram energy-saving functions and ink level monitoring - maintenance tab in the printer properties menu.

This procedure clears the memory, it does not fix clogged heads, empty cartridges. It doesn’t prevent excess ink from spilling on your desk if it is really full. For that, you need to roll up your sleeves.

Little info, ink from inkjet printers is water-soluble. No solvents like acetone or alcohol that degrade plastics. Clean with warm water and a drop of dish soap. for very dirty heads, let soak overnight. Then let dry before reassembling - a quick blow dry if you're in a hurry.

It doesn't seem to be working at my place on an S750. Let me detail the process and the state:

Turn off the printer

Okay, the light is off

- Press and hold the resume button (the one that is blinking) and press the power button for a few seconds while keeping both pressed

Okay, the light turns solid green as long as we press both buttons

- Release resume then power

- We release resume: no change, the light remains green
- We release power, the printer starts normally with 7 orange blinks

- Press resume twice

- Does nothing, still blinks 7 times orange and 1 green

No point in going further, I think

So I don't see where my mistake is.

I had the same problem with my Canon i950.
I took it apart (very easy), but the felt was still in very good condition.
(Before it overflows, there is really plenty of room!
I cleaned everything, put the printer back together, reinserted the print head soaked in water, and it still didn't work. Here’s what you really need to do:
1. Unplug the power cable
2. Press the power and resume buttons at the same time
3. While holding down the two buttons, plug in the 220W cable and keep the buttons pressed for 30 seconds.
4. After releasing the buttons, the light stays green and it’s impossible to turn off the printer with the power button.
5. Unplug the 220W cable, plug it back in. The printer will initialize and it should work!

PS: Please let me know if I was of any help.

Thank you very much for a Canon S520. It was the last solution (resetting the error memory) that worked, not the unplugging and replugging and general cleaning, which probably helped as well.

Finally, I celebrated victory too quickly. The fix did stabilize the green light, but the printer keeps making the same error afterward, even after cleaning, uninstalling, and reinstalling!!!
