Question about HP Photosmart 7450 InkJet Printer
I installed new cartridge and the on button is blinking red and the printer will not print.
Sounds like the cartridge is not correctly seated. Try taking out the cartridge, check that it is the correct one for your printer. Then re-insert it. There should be a positive click when it is correctly seated. You can check the 'feel' of this if you still have the old cartridge. You need to be firm, but not rough. Some printers/cartridges are quite stiff. You may need to align the cartridge after re-inserting it. Check the display on the printer and be sure to do the test print if offered. There may also be pop-up instructions on your computer.
