5 Locate and check on sight the print head resistor line.
6 Clean the print head resistor line.
Gently pass over the resistor line a few times with a lint free cloth, slightly moistened
with Isopropyl alcohol or Ethanol. Do this in only one direction, i.e. from left to
right, without lifting the cloth.
Be careful not to touch the print head resistor line.
Do not apply any pressure on the print head because this pressure may cause
damage on the interconnections underneath the print head.
