Replacing the Paper Feed and Separation Rollers | Xerox 4799

Scanner Options, Maintenance and Troubleshooting

When replacing the rollers described in this section, you should replace all of the rollers at the same time. Do not replace just one roller and not the other. When you are finished replacing the roller, reset the roller count in the user utility as described on page 172.

Warning: keep all replaceable parts out of the reach of children. These parts are small and pose a choking hazard.

Turn off the scanner power then unplug the power cord from the scanner. Pull the cover release handle and open the scanner.

When you are done replacing the rollers, close the scanner carefully pressing down on both sides of the cover until it locks in place. Do not slam down the cover.
