Brake roller for the Ricoh SP-2230N / SP-2240N A4 document scanners.
Consumables need to be replaced periodically. It is recommended that you keep a stock of new consumables and replace them before it reaches the end of the consumable life. Also, the scanner records the number of sheets scanned for each consumable (brake roller and pick roller), which allows you to determine when to replace the consumables.
Suggested Replacement Cycle - Every 200,000 sheets.
