Question about HP 640 Inkjet Fax Machine
It will not send or receive a fax if the error is still there. Clear the error by trying these steps:
-open cartridge door and remove the cartridge
-unplug the power cord at the back of printer
-after 30 seconds, plug the cord and turn on the printer. It will ask for the cartridge.
-Open the cartridge door and insert the cartridge
-close the access door
-if the error is cleared, try faxing again.
I hope this helps.

1. Look at the indicator light on your Lexmark printer.
You'll need to replace ink cartridges when the light flashes or turns red
instead of the standard green.
2. Purchase Lexmark ink cartridges. You can buy the brand
name or purchase a generic version that is compatible with your printer. You
can shop for low cost ink cartridges from ABC Ink.
3. Remove the old cartridges from your printer. Grip the
sides of the Lexmark ink cartridges and pull it out. Dispose of the ink
cartridges in a recycle program like the one at Staples or save the cartridges
4. Install the new ink cartridges after removing the
protective tabs. Avoid touching the IC chip when installing the new Lexmark ink
cartridges. Replace the cover of the printer.
5. Allow the Lexmark printer to run a nozzle test. Print
several pages with the new ink cartridges to make sure you installed the ink
cartridges correctly. The indicator light should return to a solid green color.
