I need to align the 5510. lines are broken and

take out the cartridges from the printer and clean the contact points with a clean piece of cloth. and then unplug the power cable from the back of the printer,then press and hold down the # and 6 button from the front panel of the printer. and while pressing them down plug back the power cable back into the printer. try to power on the printer and then insert the carridges one by one into the printer.
the printer will re-align the cartridges once.
