Power-on operation confirmed, but black ink is streaky. I thought the ink was empty, so I replaced the black ink with an Ecorica-made compatible ink cartridge, but the black ink is still streaky and doesn't print well. I am not familiar with this, so I am looking for someone who can fix it as is. Please check the photos and understand the condition before purchasing. Includes the main unit, a set of charging adapters, the replaced genuine black ink (unknown remaining amount), and one unused Ecorica compatible black ink cartridge. The Ecorica black ink used for the operation check is almost new as it was just replaced. Everything in the photos is included. (The USB cable used for the operation check is not included.)
