How to Fix White Ink Issue on F13 Pro

01 White ink is prone to settling, which can cause thin white ink output or broken lines in the print head test page.	02 Check the white ink volume; ensure it remains above the 1/3 mark to avoid printing problems.	03 Clean the print heads via the software.
04 Print a nozzle test page to inspect the print head status.	05 If the test page still shows white broken lines, draw 3ml of ink from the ink cartridge.	06 Draw 5ml of ink from the waste ink tube.
07 Use the flushing function in the software, then print another test page to recheck the print head status.	08 If broken lines persist, repeat the cleaning and ink extraction process 2–3 times.	09 If the issue remains unresolved, replace the print head with a new one.
10 Do not inject ink with a syringe to clear print heads — improper handling can damage both the print heads and the motherboard.
