The 6 flashes says that the inner cover is open, there is a switch on the right, inside that is pressed when the cover is closed. These switches fail quite often. You can try blowing canned air into the openings on the right side inside near the switch and opening and closing several times to clean the switch contacts, but this printer has no service or parts as it was exchanged for new during warranty and tossed after warranty runs out.
