Any suggestions on how to fix this. Been thro all the usual change cartridges, clean heads (several times), align cartridges.
Problem started after Low ink warning and then changing cartridges.
Need to set printer to BEST print mode to get black text in only light grey and Greyscale printing has to be set to OFF, otherwise no visible print is achieved.
Colurs look OK on Test Print but again no sharp blacks, only light grey show up.
Help Please!!
