I have hardly used my A646 printer and it is coming up with the message "open the print-carriage access door, clear the jam, and then press ok to continue", How do I do this???

Hi Brit

HP PHOTOSMART A646 PRINT CARRIAGE JAM

It would seem that there is some papar or some other foreign object obstructing the the passage of the print head carriage in you printer.

Look carefully at the paper input and output trays to see if any paper of foreign object is jammed.

Then look carefully at the ink cartridge compartment to see if the cartridges are properly clicked into place and that all the sealing tapes and plastic clips have been removed from the cartridges. Check that nothing is blocking the free movement of the print head. When closing the door the to the ink cartridge compartment, make sure that the door is closed properly.

Then power off your printer, power it up again and test it again. If the error message appears again, press OK on the printer's control panel and test again.

A PDF copy of the printer manual is downloadable from here in case you do not have access to the printer's original manual:

Good luck.

I hope this helps.
