Product Details
xBefore payment: Please confirm stock, shipping method, duties, and compatibility with us before payment. Some printer parts, printheads, fluids, and special-order items may require manual confirmation before shipment.
Compatibility and troubleshooting note: This encoder strip is a model-reference replacement part for compatible printer maintenance. It may be relevant when the installed encoder strip is dirty, scratched, worn, or unreadable. Actual troubleshooting results depend on the sensor, carriage system, board, installation, and root cause of the printer issue.
Roland Raster Encoder Strip for XJ640 / SJ640 Printing Printer may be relevant when troubleshooting carriage reading, print shifting, double image, or motion instability if the reference optical encoder strip is dirty, scratched, aged, or unreadable.
This page is designed to help you judge three things quickly: whether this product is relevant to your current fault, which option you should choose, and what technical information should be checked before you place the order.
Fitment and Troubleshooting Notes
- May be relevant when checking positioning, ghosting, or offset symptoms after the full carriage system is inspected
- Signal behavior depends on the encoder sensor, carriage system, board condition, installation, and printer setup
- Confirm model, strip length, sensor type, and installation details before ordering

Common Fault Scenarios This Part Helps Address
- Print shifting, double image, or ghosting appears because the carriage can no longer read the strip correctly
- Encoder error or signal instability starts after the reference strip becomes dirty, scratched, stretched, or aged
- Carriage shaking or unstable movement appears even though the motor and belt are still usable
Choose The Right Option Before You Order
Choose the option based on what you actually need to replace, not only by product title. If you are uncertain, send your old part photo and connector view before payment.

Compatibility Checkpoints
- Referenced printer models: XJ640, SJ640, XJ-640, SJ-640, VS-540, VP-540, SP-540, RS-540, SC-540, XC-540, LEC-540, VS-640, RS-640, RA-640, RE-640, RF-640, EJ-640, LEJ-640, SJ-740, XJ-740, SJ-1000.
- Typical equipment range: Large-format and roll-to-roll printers.
- Mainboard system such as Hoson, BYHX, or similar controller should be confirmed by machine model or board photo before payment.
- If your machine uses a specific encoder-strip resolution, send the reference strip or service note for confirmation.
- Matched encoder strip or reading standard: Model-specific optical encoder strip.
- If you are not sure, send the printer model, the carriage photo, and the old part photo so we can help confirm fit before shipment.
Best practice: send your printer model, mainboard system, connector photo, and old part number. That makes compatibility confirmation much faster and lowers wrong-order risk.

Installation And Use Notes
- Turn off the machine before installation and align the decoder with the encoder strip or motion path correctly.
- Keep the sensor window and encoder strip clean, and avoid touching the optical reading area with bare fingers.
- Check cable routing, connector direction, and mounting position before powering the printer back on.
- Before final startup, make sure the line is connected correctly and the strip-to-sensor gap is consistent.
- After replacement, test carriage travel and confirm the machine no longer shows print shifting, double image, carriage shaking, encoder error, or signal instability.
Support And Buying Confidence
- Compatibility confirmation before shipment helps help evaluate wrong-part risk.
- Support is available for model review, connector check, and basic replacement questions.
- Many products support multiple printer models, but industrial printer parts often have multiple revisions, so part-number and photo confirmation is strongly recommended.
- Fast response is available for quotation, sample discussion, and export-order questions.
- If needed, you can send your printer model or machine photo before ordering and we will help review fit first.
