Non-removable CRU light shield replacement for pull strip
This is a shroud for housing a replacement photoconductive drum. The shroud has an open gap at its top portion and this gap is covered by at least two overlapping flexible strips that are configured to allow a handle structure to pass therethrough on its way to an exit in the shroud where the photoconductive drum is pushed out of the shroud when installing the drum in a marking machine.
1. A shroud for housing a replacement photoconductive drum, said shroud comprising:
an elongated housing configured to house a photoconductive drum,
said housing being entirely enclosed except for an exit open portion and a gap on its top portion which extends throughout substantially the length of said housing and terminating at said exit,
positioned over said gap is at least two separate overlapping flexible strips,
said strips configured to permit a movable handle structure to travel therebetween to said exit when removing said photoconductive drum from said shroud.
2. The shroud of claim 1 wherein said movable handle is configured to move said drum toward said exit during a drum replacement procedure.
3. The shroud of claim 1 having on one first end portion a closed structure, and on an opposite second end portion an open end to act as an exit location for said drum.
4. The shroud of claim 1 wherein said strips are constructed of a flexible material selected from the group consisting of plastic, rubber, paper, cloth and mixtures thereof.
5. The shroud of claim 1 wherein said strips extend through substantially the entire length of said gap, and wherein one side of said strip is attached to said shroud, and another opposite end overlaps at a center gap location with the other strip.
6. The shroud of claim 1 wherein said strips are configured to allow passage of said handle at said overlapping portions of said strips.
7. A shroud for housing a replacement photoconductive drum, said shroud comprising:
an elongated housing configured to house a photoconductive drum,
said housing being entirely enclosed except for an exit open portion and a gap on its top portion which extends throughout substantially the length of said housing and terminating at said exit,
positioned over said gap is at least two separate overlapping flexible strips,
said strips configured to permit a movable handle structure to travel therebetween to said exit when removing said photoconductive drum from said shroud,
said flexible strips overlapping approximately 1-5 mm directly over said gap, and flexible enough to bend upon installation of said replaceable photoconductive drum,
said strips configured to provide light protection to said drum while it is removed from said shroud.
8. The shroud of claim 7 wherein said movable handle is configured to move said drum toward said exit during a drum replacement procedure.
9. The shroud of claim 7 having on one first end portion a closed structure, and on an opposite second end portion an open end to act as an exit location for said drum.
10. The shroud of claim 7 wherein said strips are constructed of a flexible material selected from the group consisting of plastic, rubber, paper, cloth and mixtures thereof.
11. The shroud of claim 7 wherein said strips extend through substantially the entire length of said gap, and wherein one side of said strip is attached to said shroud, and another opposite end overlaps at a center gap location with the other strip.
12. The shroud of claim 7 wherein said strips are configured to allow passage of said handle at said overlapping portions of said strips.
