Hp Latex 360 squeaks

[PMDLLC]

HP Latex 360 carriage squeaks or something is squeaking as it makes passes back toward maintainance cartridge. It makes a squeak noise when moving to the left. No print errors and prints are perfect. Printer starts up and all checks are a go. Just this horrible squeaking. Tension belt was replaced back in Sept/Oct 2021. No issues since tech install it back months ago. Just a couple weeks ago starting noticing the squeaks as carriage moves to left.

Is it the print heads needing replaced? Any insight would be helpful. Thanks.

According to my experience,

squeaking is generated from tensioner or carriage rail. Please lubricate the rail and tensioner.

Also, check for carriage brushes, sometimes they are worn off, the location is the undercarriage unit.

The last thing you need to check is the plotter standing on a flat surface?

Thank you. After speaking with a tech they wanted to come a replace the tensioner belt, although it was just replaced last year. I took the liberty and scoped out where squeaking was coming from. Low and beyond, it was the tensioner plate attached to end of printer. Dropped a few drops of oil on those springs and outside of tiny wheel rod that the belt goes around. Boom squeaking immediately went away and has been good since Friday. Yay!!!! Thing was driving me nutts.
