HP Laser jet Pro MFP M28-M31 has been working well with the catridge I have but suddenly started to print a grey background on all the printed pages. I get no help from the instructions given by HP Support Assistant. For example, cannot find a way to "print a cleaning page". The age of the printer or the catridge should not be an issue. Any help on this is greatly appreciated.
