How often do I have to replace the lamps, separator roller, and skimmer tires or glass flat on an 8000 Plus?
There is not a finite replacement period for the skimmer rollers but they are rated to last 500,000 document scans (at minimum). The Separator roller sleeve is rated to last six months, assuming 5,000 pages per day. Lamps are rated to last up to six months, assuming 5,000 pages per day. The lamp is rated to last three months in color dropout mode.
