The PCR holders will most likely come out with the PCR. This is OK. It makes it easier to re-install it later. Be very careful not to touch the roller with your skin. As with any PCR, the oils naturally present in your skin will be absorbed by the roller and cause printing problems (extra marks on the page). 5. Remove the two screws from the wiper blade. 6. Remove the wiper blade, and clean out any waste toner. www.uninetimaging.com © 2010 UniNet Imaging Inc. All trademark names and artwork are property of their respective owners.
