The Roland VS-640 / RE-640 / RA-640 Head Data Cable Set is a complete 4-piece replacement cable kit for Roland VersaCAMM VS, RE, RA, and XF series eco-solvent print-and-cut printers. The set contains the exact combination of cables required for one full printhead replacement: three 29-pin cables (Roland part 1000006702, 256mm × 30mm) and one 28-pin cable (Roland part 1000006703, 276mm × 30mm). These flat flexible cables (FFC) connect the printhead to the printer's carriage control board, transmitting the nozzle firing signals that drive the Roland DX5/DX6 head. Replacing the complete 4-cable set at every printhead installation is the correct service procedure — leaving any worn cable in place causes residual communication errors on the new head.
This set contains exactly the 4 cables required for one complete Roland VS/RE/RA head replacement. The Roland DX5/DX6 printhead in VS-640, RE-640, RA-640, and XF-640 printers requires 3× part 1000006702 (29-pin) and 1× part 1000006703 (28-pin) — four cables total. Replacing fewer than all four leaves residual wear in the remaining cable(s), causing nozzle drop-out and banding indistinguishable from a defective printhead. This listing provides the complete set as a single order.

Why This Set Uses Two Different Cable Types
The Roland DX5/DX6 printhead in VS/RE/RA series printers uses four data cables with a specific configuration: three cables carry the main nozzle firing channel data (29-pin, 1000006702) while one cable carries a slightly different signal path — the 28-pin 1000006703 differs by one pin in its connector layout, handling a distinct power and control signal channel. Using the wrong cable in the wrong position will cause incorrect signals to reach specific nozzle rows, producing systematic colour channel errors. Always route each cable back to its original socket — photograph the cable positions before removal or mark each cable with a coloured label prior to disconnecting, as the four connectors are physically similar in arrangement.
Why Data Cables Fail — and Why Replacing All Four Matters
Each of the four cables travels with the carriage on every print pass — flexing thousands of times per day. Micro-fractures develop in the conductor traces at flex points over time, causing intermittent or permanent signal loss on specific pins. On this 4-cable platform, partial replacement is a common mistake: replacing two or three cables while leaving one original in place means the residual wear in the old cable will continue to cause nozzle communication errors after the head swap. Symptoms of worn cables include:
• Missing nozzle rows on a nozzle check — specific colour channels dropping out
• Horizontal banding in output at regular intervals
• Complete colour channel loss while others fire normally
• Intermittent errors that vary with print speed or temperature
• Nozzle problems appearing immediately after a new printhead is installed — often misdiagnosed as a defective head
Roland VS/RE/RA Printhead Installation — Full Consumable Checklist
For a complete and reliable head replacement on the Roland VS-640, RE-640, RA-640, or XF-640, replace these consumables simultaneously:
• Head data cables (this listing) — complete 4-cable set, never reuse old cables
• Dampers — worn ink dampers restrict flow to the new head and cause starvation
• Capping station — a degraded cap prevents proper head sealing, causing drying and nozzle clogging on new heads
• Wiper blade — worn wipers deposit residue and debris on the nozzle face during maintenance cycles

Frequently Asked Questions
Why does this set contain 3 cables of one type and 1 of another?
The Roland DX5/DX6 printhead in VS/RE/RA series printers uses a 4-cable data interface with two different cable specifications: three 29-pin cables (1000006702, 256mm) carry the main nozzle firing channel data, while one 28-pin cable (1000006703, 276mm) handles a distinct signal path with a slightly different connector layout. This mixed-cable architecture is Roland's design for the DX5/DX6 head — you cannot substitute all four with the same cable type. This set provides the correct mix in one order.
Is 1000006703 the same as 1000006704?
The correct Roland part number for the 28-pin cable in this set is 1000006703. Part number 1000006704 may appear in some listings as a data entry variant, but 1000006703 is the confirmed Roland part designation for the Cable-Card 29P1 276L BBR High-V. If your service documentation references 1000006704, contact us to confirm the correct cable before ordering.
Can I use these cables on a Roland XC-540 or BN-20?
No. The XC-540 uses the DX4 printhead with a different 21-pin cable interface (Roland part 22805470). The BN-20 uses a DX4-based head with yet another cable configuration. The 1000006702/1000006703 cable set is specific to the DX5/DX6-based VS/RE/RA/XF series. Always verify the printhead generation in your printer before ordering cables.
Do you ship Roland VS-640 data cables to Latin America?
Yes — same day shipping from our Doral, Miami FL warehouse. Ideal for Latin American Roland service centres, sign shops, and print-and-cut operations running VS/RE/RA/XF series printers via Miami freight forwarders.
