Abstract
The print head cover () of an electrostatic deflection inkjet printer is made of a material having an electrical surface resistivity of no more than 10ohms per square or an electrical volume resistivity of no more than 10ohm metres and is electrically connected to an earth line (). This prevents build-up of electric charge on the cover (). The resistance from the surface of the cover () to a place where a cover earth line () joins a signal earth line () or enters the umbilical () is at least 16000 times the resistance from that place to earth. This prevents an electrostatic discharge to the cover () disrupting the electronic circuits. The high resistance earth connection for the cover () avoids the need for an earthing wire braid in the umbilical (). The cover () may be moulded from an antistatic or static dissipative material.
