Photo #2: Front End
the underside of the rear end cover. It is held in place by a pair of clips which you’ll need to depress to slide the chip off. Here you’ll also find a ring-shaped finger catch which will now fall right off. 3. Remove the charge roller (PCR) assembly (2 screws from the left side). 4. You can now take the charge roller right out of its cradle bearings and the cleaning roll will also come right out.
5. Turn the cartridge on its left side and walk the front drum bearing/ clip off the end of the drum. Then walk the rear drum bearing/clip off of the rear end. Each of these bearing/clip pieces requires a little bit of jiggling to extract them straight off the ends of the cartridge. The rear one can be particularly stubborn (jiggle it up and down to walk it off the end). 6. Lift the drum out of its cradle (see photo #7) 7. Remove the drum cleaning blade (2 screws). 8. Save some of the toner to use later as starting powder for the new drum and blade. Then clean out the plastic cleaning auger (this is a huge improvement over earlier models which used metal springs as augers. I’m very happy to see an auger this sturdy). Take care not to damage the mylar recovery blade (seal blade) while you vacuum this area. 9. Reassemble the cartridge. Ideally, you should reassemble with a new

drum, charge roll, cleaning roll, blade, and CRUM chip. Note 1: Starting Powder - Make sure the drum and the edge of the cleaning blade have starting powder on them (or use the toner you recovered in the previous step as starting powder). After the drum and blade are back in place, rotate the drum several times by hand to make sure the drum rotates smoothly and easily and that the blade doesn’t get hung up. The blade should clean any starting powder off of the drum completely. After the drum is properly started, you can reinstall the charge corona assembly. Note 2: Greasing the Charge Roller – Clean off any old grease from the charge roll cradle bearings and apply fresh grease sparingly. Too much grease can migrate to other components in the cartridge and ruin the copy quality. Conductive grease is recommended here. Avoid getting grease on the black ferrite bead that is spring loaded against the rear end of the charge roll’s shaft. That black piece is the contact terminal for the charge. That’s all there is to it! Nice and simple. The Versants will eventually replace the entire line of DocuColor 250 style machines. It’s good to see they are their equal or possibly even better in some ways. Happy cartridge rebuilding everyone! Have a wonderful summer. ♦ July 2017 | www.enxmag.com
