Question: I wanted to change my desktop printer from Matte Black to Photo Black. But the printer reported that there is not enough ink to execute this action. What can I do?
Desktop printer models require you install a cart that is at least 1/2 full to change black carts/inks. So, if your using MK and want to switch to PK, but the PK cart chip reads less than 1/2 full, the printer will not allow you to install the partially used PK cart until you first install a PK with over 1/2 ink remaining.
I actually have new Epson MK + PK carts for this exact thing- just to trick the printer to do the black ink change, then I am able to install my less than full ConeColor refillable cart and continue printing. It’s a good idea to keep this in mind when removing a cart- check the status monitor ink level first and if it’s less than 1/2 you may want to make some more prints or use it up so it reads empty, then remove + reinsert to reset to full, then you can remove it and use it later when you want to switch back.
