my hp envy 6455 is flashing E O

[gmiiii]

Printer wouldn't print, flashing E on the info board - put paper in and drawer wouldn't close all the way - removed some paper from drawer and got it to close - still wouldn't print - unplugged / plugged back in and still not working -  printer sent out a torn piece of paper and found the other piece of paper when the printer was flipped over. Opened up the top and found no problems. Continued to flash E O.

@gmiiii, Welcome to the HP Support Community! I’m here to help.

I understand you are not able to print. 

An E0 error indicates an unusable cartridge.

This condition occurs when at least one ink cartridge needs attention, is faulty, incorrect, missing, damaged, or incompatible. Reseat both ink cartridges, clean the ink cartridge contacts, restart the printer, and replace one or both ink cartridges if necessary.

Perform the steps mentioned in this document - Ink cartridge errors

Insert one ink cartridge at a time to identify the defective ink cartridge.

Also, make sure the input tray is properly installed, refer to - Replacing Input Tray

Check for any jams inside the printer - E4 (Paper jam) error

Make sure the printer carriage is moving freely. 

Try making a standalone copy from the flatbed glass and check if that works. By this, we can conclude if this is a hardware or a driver issue.

Hope this helps! Keep me posted.
