7.3 Replace the Feed Roller
The feed roller and separation pad inside the scanner wear with scanning. If the feed roller
and separation pad are worn, documents may not feed correctly and paper jams may occur.
When document feed performance deteriorates, replace the feed roller and separation pad.
Note:
It is recommended to replace the feed roller or separation pad when the total number of
pages of documents fed in the scanner exceeds one of the following quantities:
Feed Roller: 100,000 sheets
Separation Pad: 10,000 sheets
Follow these steps to replace the separation pad and feed roller.
To replace the Feed Roller,
1. Open the feed tray.
2. Open the feeder cover.
