## Abstract

An example device can include a reserve print materials container, an access port coupled to the reserve print materials container to receive, from a replenishment device, print materials directly to the reserve print materials container in-situ, and a main print materials container coupled to the reserve print materials container to receive print materials from the reserve print materials container.

## Claims

### Claim 1

A device, comprising:
a reserve print materials container;
an access port coupled to the reserve print materials container to receive, from a replenishment device, print materials directly to the reserve print materials container in-situ; and
a main print materials container coupled to the reserve print materials container to receive print materials from the reserve print materials container.

### Claim 2 (depends on 1)

The device of claim 1, wherein:
the device is located within a printing device; and
the device further comprises an organic photo conductor drum (OPC) resiliently coupled to the device.

### Claim 3 (depends on 1)

The device of claim 1, further comprising the reserve print materials container supplying the main print materials container with print materials responsive to an indication of the print materials falling below a threshold in the main print materials container.

### Claim 4 (depends on 1)

The device of claim 1, wherein the reserve print materials container is a reserve print material particles container.

### Claim 5 (depends on 1)

The device of claim 1, wherein:
the device is located within a printing device; and
the reserve print materials container, the access port, and the main print materials container comprise a combination cartridge device.

### Claim 6 (depends on 5)

The device of claim 5, wherein the combination cartridge device further comprises an organic photo conductor drum (OPC), a waste collection container, and a developer roller.

### Claim 7

A system, comprising:
a combination cartridge device, comprising:
an organic photo conductor drum (OPC);
a developer roller;
a main print materials container;
a waste collection container;
an access port coupled to the main print materials container to receive, from a replenishment device, print materials directly to the main print materials container in-situ; and
a replenishment device resiliently coupled to the access port.

### Claim 8 (depends on 7)

The system of claim 7, wherein the replenishment device comprises a plunger mechanism for deployment of print materials into the main print materials container.

### Claim 9 (depends on 7)

The system of claim 7, further comprising a waste collection container to collect and store waste.

### Claim 10 (depends on 7)

The system of claim 7, further comprising the replenishment device resiliently coupled to the access port via an interlocking connection.

### Claim 11 (depends on 7)

The system of claim 7, wherein the combination cartridge device further comprises an additional waste collection container.

### Claim 12 (depends on 7)

The system of claim 7, wherein:
the replenishment device includes a plunger mechanism for deployment of print materials into the main print materials container; and
the plunger mechanism is locked upon completion of the deployment.

### Claim 13

A method, comprising:
receiving a replenishment device at an access port of a cartridge device while the cartridge device is in a printing device;
receiving print materials deployed from the replenishment device at a print materials container of the cartridge device while the cartridge device is in the printing device;
performing a print job using the print materials;
collecting waste to a first waste collection container of the cartridge device; and
moving the waste to a second waste collection container of the cartridge device for storage of the waste.

### Claim 14 (depends on 13)

The method of claim 13, further comprising:
receiving the print materials at a reserve print materials container; and
moving print materials from the reserve print materials container to a main print materials container of the cartridge device using a belt.

### Claim 15 (depends on 13)

The method of claim 13, further comprising moving the waste to the second waste collection container using a belt.
