NOTES
- Always replace pick-up, feed and separation rollers as a set.
- If the copier is a B064 Series machine, check the counter value for each paper tray station with SP7204 (Copy Counter – Paper Trays). If the value has reached 300K, replace the rollers. The quality of the paper can have an effect on the service life of the rollers. Paper with a rough surface, for example, can increase abrasion on the rollers and decrease their service life. After replacing the rollers, reset the counter with SP7816 (Copy Counter Reset).
- If the feeding from the by-pass tray causes frequent jams, and the by-pass tray is not used regularly, check the by-pass tray rollers. If pick-up, feed, and separation rollers for the by-pass tray are of lighter color than those of more frequently used trays, replace them.
