An apparatus includes a photoreceptor belt, a fixed transfer roller positioned on the inside of the photoreceptor belt, and a movable transfer roller positioned on the outside of the photoreceptor belt. The fixed transfer roller and the movable transfer roller are positioned to form a nip, and the photoreceptor belt and a web of print media are positioned in the nip. Also, a support roller and a compensation roller contact the web of print media. The support roller is positioned between the compensation roller and the nip. A physical link is connected to the support roller and the compensation roller. The physical link moves the support roller and the compensation roller so as to keep a constant tension on the web of print media. |

| Claim: |
1. An apparatus comprising: a photoreceptor belt; a fixed transfer roller positioned on a first side of said photoreceptor belt; a movable transfer roller positioned on a second side of said photoreceptor belt opposite said first side, said fixed transfer roller and said movable transfer roller being positioned to form a nip, said photoreceptor belt and a web of print media being positioned in said nip; a support roller contacting said web of print media; a compensation roller contacting said web of print media, said support roller being positioned between said compensation roller and said nip; and a physical link connected to said compensation roller, said physical link simultaneously moving said compensation roller as said movable transfer roller moves. |
| Claim: |
2. The apparatus according to claim 1, said support roller and said compensation roller being on one of the same side and the opposite sides of said web of print media depending on the tension compensation requirement. |
| Claim: |
3. The apparatus according to claim 1, said physical link moving said support roller and said compensation roller in a first direction away from said photoreceptor belt and in a second direction toward from said photoreceptor belt. |
| Claim: |
4. The apparatus according to claim 1, said physical link comprising a bar connected to axis of said support roller and said compensation roller. |
| Claim: |
5. The apparatus according to claim 1, said support roller being approximately centered between said compensation roller and said nip. |
| Claim: |
6. An apparatus comprising: a photoreceptor belt; a fixed transfer roller positioned on a first side of said photoreceptor belt; a movable transfer roller positioned on a second side of said photoreceptor belt opposite said first side, said fixed transfer roller and said movable transfer roller being positioned to form a nip, said photoreceptor belt and a web of print media being positioned in said nip; a support roller contacting said web of print media; a compensation roller contacting said web of print media, said support roller being positioned between said compensation roller and said nip; and a physical link connected to said support roller and said compensation roller, said physical link simultaneously moving said support roller and said compensation roller as said movable transfer roller moves. |
| Claim: |
7. The apparatus according to claim 6, said support roller and said compensation roller being on one of the same side and opposite sides of said web of print media depending on the tension compensation requirement. |
| Claim: |
8. The apparatus according to claim 6, said physical link moving said support roller and said compensation roller in a first direction away from said photoreceptor belt and in a second direction toward from said photoreceptor belt. |
| Claim: |
9. The apparatus according to claim 6, said physical link comprising a bar connected to axis of said movable transfer roller, said support roller, and said compensation roller. |
| Claim: |
10. The apparatus according to claim 6, said support roller being approximately centered between said compensation roller and said nip. |
| Claim: |
11. An apparatus comprising: a photoreceptor belt; a fixed transfer roller positioned on a first side of said photoreceptor belt; a movable transfer roller positioned on a second side of said photoreceptor belt opposite said first side, said fixed transfer roller and said movable transfer roller being positioned to form a nip, said photoreceptor belt and a web of print media being positioned in said nip; an actuator connected to and moving said movable transfer roller; a support roller contacting said web of print media; a cam contacting said movable transfer roller and said support roller, said cam causing said support roller to move as said actuator moves said movable transfer roller; a compensation roller contacting said web of print media, said support roller being positioned between said compensation roller and said nip; and a physical link connected to said support roller and said compensation roller, said physical link simultaneously moving said compensation roller as said support roller moves. |
| Claim: |
12. The apparatus according to claim 11, said support roller and said compensation roller being on opposite sides of said web of print media. |
| Claim: |
13. The apparatus according to claim 11, said physical link moving said support roller and said compensation roller in a first direction away from said photoreceptor belt and in a second direction toward from said photoreceptor belt. |
| Claim: |
14. The apparatus according to claim 11, said physical link comprising a bar connected to axis of said support roller and said compensation roller. |
| Claim: |
15. The apparatus according to claim 11, said support roller being approximately centered between said compensation roller and said nip. |
| Claim: |
16. An apparatus comprising: a photoreceptor belt; a fixed transfer roller positioned on a first side of said photoreceptor belt; a movable transfer roller positioned on a second side of said photoreceptor belt opposite said first side, said fixed transfer roller and said movable transfer roller being positioned to form a nip, said photoreceptor belt and a web of print media being positioned in said nip; an actuator connected to and moving said movable transfer roller; a support roller contacting said web of print media; a compensation roller contacting said web of print media, said support roller being positioned between said compensation roller and said nip; and a physical link connected to said movable transfer roller, said support roller, and said compensation roller, said physical link simultaneously moving said support roller and said compensation roller as said actuator moves said movable transfer roller. |
| Claim: |
17. The apparatus according to claim 16, said support roller and said compensation roller being on opposite sides of said web of print media. |
| Claim: |
18. The apparatus according to claim 16, said physical link moving said movable transfer roller, said support roller, and said compensation roller in a first direction away from said photoreceptor belt and in a second direction toward from said photoreceptor belt. |
| Claim: |
19. The apparatus according to claim 16, said physical link comprising a bar connected to axis of said movable transfer roller, said support roller, and said compensation roller. |
| Claim: |
