## Abstract

Systems and methods of remanufacturing an imaging cartridge including the replacement a rotatable member, such as an organic photo conductor (OPC) drum or toner adder roller, for example, in the imaging cartridge without detaching the rotatable member retaining elements, such as end caps, for example, and installing a replacement rotatable element without disturbing the rotatable member retaining elements end caps.

## Claims

### Claim 1

A method of remanufacturing an imaging cartridge comprising:
providing the imaging cartridge comprising a rotatable member retaining element including an opening;
providing a replacement rotatable member including an internal retaining member;
placing the rotatable member proximate the rotatable member retaining element;
inserting an external hub into said opening of the rotatable member retaining element; and
attaching the external hub to the internal retaining member.

### Claim 2 (depends on 1)

The method of claim 1 wherein the internal retaining member partially extends from the interior of the rotatable member.

### Claim 3 (depends on 1)

The method of claim 1 wherein the step of inserting the external hub is performed before the step of placing the rotatable member.

### Claim 4

A method of remanufacturing an imaging cartridge comprising:
providing the imaging cartridge comprising a rotatable member retaining element including an opening;
providing a replacement rotatable member including an internal hub;
placing the rotatable proximate the rotatable member retaining element; and
withdrawing at least a portion of the internal hub into said opening of the rotatable member retaining element.

### Claim 5

A method of remanufacturing an imaging cartridge comprising:
providing the imaging cartridge comprising a rotatable member retaining element including an opening;
providing a replacement rotatable member;
placing the rotatable member proximate the rotatable member retaining element; and
inserting at least a portion of a shaft through said opening of the rotatable member retaining element and at least partially into the rotatable member.

### Claim 6 (depends on 5)

The method of claim 5 wherein one portion of the shaft comprises a hub sized to rotatably engage the opening of the rotatable member retaining element.

### Claim 7

A method of remanufacturing an imaging cartridge comprising:
providing the imaging cartridge comprising a rotatable member retaining element including an opening;
providing a replacement rotatable member;
placing the rotatable member proximate the rotatable member retaining element; and
inserting at least a portion of a hub through said opening of the rotatable member retaining element and at least partially into the rotatable member.

### Claim 8

A method of remanufacturing an imaging cartridge comprising:
providing the imaging cartridge comprising a rotatable member retaining element including an opening;
providing a replacement rotatable member including a first portion of a hub;
placing the rotatable member proximate the rotatable member retaining element;
inserting a second portion of the hub into said opening of the rotatable member retaining element; and
attaching the first portion of the hub to the second portion of the hub.

### Claim 9 (depends on 8)

The method of claim 8 wherein the second portion of the hub comprises a gear.

### Claim 10 (depends on 9)

The method of claim 9 wherein the gear comprises a tri-lobe gear.
