If one or more of the ink colours is missing from pages printed by your machine (i.e. received faxes, copies and/or documents printed from the PC), the nozzles or ink jets in the print head may be clogged, or the ink cartridge in question may not be installed correctly. Verifying that the ink cartridges are installed correctly and/or cleaning the print head may resolve this prolem.
