Question about Canon SmartBase MP390 All-In-One InkJet Printer
I have soaked in water and blown out the print head. Replaced cartridges and did the blow in straw to 'prime' the print head.
The Print Head in your printer is physically damaged and so even though it is present and installed it will not be detected by the Printer, you need to purchase and install a new print head for your printer.

Use the printer's utility program to self-clean the printer.
This process may need to be repeated as many as 5 to 10 times. Often this will
resolve the problem.
Turn the printer off, preferably overnight, if the self-cleaning
utility has not worked. The ink may need to soften before the self-cleaning
utility will be successful. Turn the printer on and try the self-cleaning
utility again several times.
from the owner's manual where the print head is located. Epson printers, for
example, are usually in the printer. Many other brands place the print head in
the cartridge. For models where the print head is in the printer, drop seven to
10 drops of isopropyl alcohol (rubbing alcohol) down the ink receptacle area.
This is the hole where the ink flows into the head from the cartridge. Run a
few self-cleaning utilities. If necessary, allow to sit a few hours or
overnight and repeat the self-cleaning utility.
cartridge print head in hot water if the print head is in the cartridge. Allow
to soak overnight. Dry the print head area with a paper towel. Repeat the
cartridge print head in isopropyl alcohol if the hot water soak did not unclog
the print head. Leave the print head covered in alcohol overnight. Use a damp
paper towel to wipe off the print head area. Dry carefully. Try the
self-cleaning utility again.
a new cartridge if the alcohol soak did not unclog the print head in the
cartridge. This will provide new print heads that won't be clogged. Contact a
service technician for repair of print heads in the printer if the alcohol did
not unclog the print head.
