R29176000 is the middle pressure roller replacement for SATO S84-ex/S84xx-ex printers. As a dedicated spare part, it sits in the printer’s pressure assembly to apply uniform pressure on the label as it passes between the feed mechanism and platen, supporting consistent media feed and print quality. In official service literature, it is listed as the pressure roller sub-component for S84xx-ex models (ROLLER(PRESSURE)SUB S84xx-ex), confirming its role as the replacement part for the S84-ex family. This part is used by technicians when servicing SATO S84-ex systems to restore reliable feed and imaging performance.
