It's called zikzak due to looking like Z...... Please perform the line sensor calibration....if not solved please replace with all-new printheads...and try to alignment the printer..... Then check it for if not solve please check carriage bushing and carriage rail for lubricant....if there haven't any lubricant....please use lubricant and again perform printhead alignment.
