ABSTRACT:
A print head assembly with interchangeable pluggable printed circuit print heads has means for automatically positioning a head during insertion with the aim of ensuring registration of printed circuit electrodes on the head with correspondingly positioned conductors on a body portion. The print heads are supplied as a variety of types all of which are interchangeable as a simple push-fit in the body portion. A clamp ensures that ohmic contact is established and maintained between the registering electrodes and conductors. Each head is also provided with a pattern of electrodes which serve to identify the head type. The pattern bridges selected additional conductors on the body portion and provides a decodable pattern of signals in response to an interrogate signal unique to heads of that type. One of these electrodes on the head shorts a control conductor on the body portion to one or other of two adjacent guard conductors, if lateral misregistration of the head within the recess exceeds a predetermined amount.
