Wait until the printhead is bone dry, or you will lose the existing calibration! While recoverable, this will be an expensive mistake, especially with non-XL carts (1/2 cart waste with non-XL, 1/4 with XL). Your printer will run a minor cleaning cycle after printhead installation ("printhead preparation"), but wastes far less ink.

Once the printhead is satisfactorily dry, reinstall the printhed and ink in the printer. Plug the printer in.
