No longer available for purchase, contact us if you want to send us your duplexer for refurbishing. Replacing essential rollers with Genuine HP Parts. Many companies cut corners and lower prices by not replacing essential parts, especially rollers, when "refurbishing." We haven't given in to that temptation even though most customers could never tell the difference. We replace these five essential duplexer rollers using genuine HP parts, not low quality aftermarket clones.
