understand the concept: If U R replaced any one of print head in good working printer, printer detects new print head & it will try to align it with others. Printer will print align page to read, while reading if its found any other print heads are poor quality or bad condition, it will say to replace them also.. Some times it may 2,3 or all.

If UR feels its expensive, try to clean the print heads manually & try for UR luck..."
