    WF-7840 PF/EJ adjustment

    Hello everyone, I am currently facing an issue with the WF-7840 PF/EJ adjustment on my printer. I have tried adjusting the settings multiple times but still can't seem to get it right. Has anyone else experienced this problem before? Any tips or advice would be greatly appreciated. Thank you...
