ABSTRACT:
The disclosure describes in detail one of the most serious problems in connection with maintaining the operating life of print hammers at the high speeds of todays printers. Also described in detail is a structural arrangement to solve this problem without involving a major redesign of a print hammer module. A significant aspect of this solution is that a high speed print hammer is kept out of contact with structure that serves as a reservoir for the pivot pin lubricant.
