Abstract
An ink jet printer utilizes a substantially electrically conductive deflection electrode which extends generally parallel to at least one row of ink jet drop streams and has a d.c. electrical deflection potential impressed thereon to produce a static electrical deflection field through which drops in the drop streams pass. The deflection electrode is heated by passing a resistive heating current through the electrode and is held by a spring mounting arrangement to compensate for resulting thermal expansion of the electrode, thus maintaining the electrode in tension, such that it is held substantially straight.
