In this video, I walk through one of the most frustrating printer problems: a printer that runs normally but prints completely blank pages. The carriage moves, the printer makes all the normal noises, but no ink comes out. Many people immediately assume the printhead is clogged, but there are actually several possible causes. In this video, I explain the step-by-step diagnostic process I use when troubleshooting these printers.
We’ll cover:
• Checking for printhead clogs using a syringe
• How to test if the capping station is blocked
• How to tell if the waste line is working
• Inspecting the F1 and F2 fuses on the mainboard
• Understanding the driver chip that fires the printhead
• Why printers actually use a 42V energy reservoir to fire piezo nozzles
• Using the XP600 / ET-8550 printhead system as a real example
Understanding how the printer electronics, voltage, and ink system work together will help you identify the real problem instead of replacing expensive parts blindly.
If your printer prints blank pages but still moves normally, this troubleshooting process can save you a lot of time and money.
