Review on 🖨️ High Performance HP 70 Magenta & Yellow DesignJet Printhead (C9406A) for DesignJet Z5400, Z5200, Z3200, Z3100 & Z2100 Large Format Printers: Enhance Print Quality and Efficiency by Rory Stice

After having trouble cleaning the printheads on my HP Photosmart B9180, I replaced all four printheads and it looks like a new printer. Even with occasional use that sits idle for days, the prints are perfect and the heads never need cleaning. about what you get with new printheads. Replace them all at once, as the printheads will automatically realign and recalibrate when the printer detects that you are replacing one. When one color pair needs a new printhead, the others keep up, and you save time and ink by replacing all printheads at once.
