Hello HP Community,
Recently the test page is not printing the full color. On the one side of the test print, its lighter in color. Example image attached. What may be causing this and how can I fix this issue?

That the White patches vary depending on cartridge suggest an issue with the high voltage board. Have you recently changed a cartridge? If so, that cartridge might be defective and causing a voltage drop.

You appear to have some black lines as well, could be a bad black cartridge

Without swapping cartridges it is impossible to say. It could be the high voltage power supply or it might be just a cartridge.
