Remove the three screws from the bracket between the end of the carriage support and the case. Remove this bracket. With clean hands or gloves, depress the sprung bracket on the right, and release the plastic sensor strip. Then undo it from the hook on the left side. Lay it over the print head, and secure it with a clean object. It is essential that you do not crease, twist or soil this strip. Small amounts of ink can be removed with a mild solvent, such as isopropyl alcohol, but other solvents may remove the fine lines printed on it. It may be safer to remove it at this point, but it is hard to feed it back through the print head assembly.
