Registration Pin Error HandlingThree Levels of Safety:1. Before any gantry motion begins, the printer software retracts all registration pins.2. Each of 4 pin groups has a “safety zone”. When the moving gentry enters any of these zones,all pins from the appropriate group retract to provide safe gantry passage.3. If pin behavior is set to manual – the user is allowed to activate pins using the table vacuumpedals. However, if the gantry is within safety zone of any of the pin groups, that group willignore request to extend. The same is true if pins are in one of automatic operational modes.Error handlingIn case any of the pins is stuck in either UP or DOWN position, gantry motion is stopped, printingcancelled and the "registration pin error" window will pop-up. Safety zones ensure detection of apin that failed to retract and the gantry stops before it hits that pin.The pop-up error window informs the user that the software detected undesired pin position, andit will show possible reasons for the error (air pressure, sensors) and ask user to visually check ifall pins are in retracted (DOWN) position. There are two buttons in this error window - one allowsthe user to re-initialize pins and another button allows the user to completely disable the pins.Pins are automatically re-enabled on the next printer power-up, so they go through usualinitialization process.NOTEIf initialization fails, the same process of error handling repeats. In this case you must request aservice call.[3] Registration Pin Error WindowRegistration Pin MaintenanceDuring a print job with a bleed, ink will deposit on the top surface of the pins and pin housings.The accumulation of ink on these surfaces should not grow beyond the top surface of the overlay.When this occurs remove the accumulated ink by using a razor blade or scraper on the topsurface of the overlay only (with pins in the down position). It is also possible to clean the topsurface of each pin with the same tools in their UP position.IMPORTANT• Do not use any cleaning solutions to clean pins• Do not lift overlays to clean pins• Do not dig out ink from below the top surface of the overlay as this may damage the surface ofthe pin.Media Registration92 Chapter 4 - Operating the Printer
