Hello. The problem with hp officejet pro x476dw. When you turn when he begins to check cartridges, a blue screen with an error C18A000A. After that, all the buttons are flashing on the screen and writes: Printer Error . Turn off and then turn on the printer . Without cartridges or cartridges with all switched on and working, but as soon as insert all four , again a blue screen with the same error . Download the latest firmware , try to install , but says that the printer is busy . What could be the reason? What can be done ?
