red marks repeatedly appearing on printed page

pscampion · ‎12-10-2019

Hello. I have a CM2320nf MFP. It works great except color printouts are now coming out with repeated red marks on both the side edges on the printed page. The manual states to see the HP Toolboxfx but I cannot find this toolbox in my printer device nor can I find it in any software downloads.... Any other suggestions?

thank you!

Repetitive dots can be measured and a repetitive defect chart will tell you exactly what component has failed. Usually if the defects are a distinct color then that can be matched to the cartridge of that color.
