E300245 - JV4-130 Linear Encoder Scale Assembly (encoder tape)

Linear encoder scale – Mimaki JV4-130 – E300245

The Mimaki E300245 linear encoder scale (Linear Encoder Scale Assy JV4-130) is the optical scale mounted along the Y-bar of the JV4-130. The encoder sensor continuously reads it to determine the exact position of the print heads.

Its scale of 180 lines per inch (180 LPI) provides the controller with a positional reference on every pass. This precision ensures accurate drop placement and bidirectional printing without misalignment.

Supplied on its own, width 15 mm. Three options available on this product page: New (genuine Mimaki part), Refurbished (inspected genuine part) or New / Compatible (strip custom-manufactured by DG Spare Parts).

‘New / Compatible’ version – custom-made by DG Spare Parts

• Strip cut in our workshop from a generic 180 LPI encoder strip, 15 mm wide.
• Exact measurements are essential: please specify the total length of your original tape, including the fixing holes, when placing your order. Without this measurement, the order cannot be sent for production.
• Supplied without mounting holes: these must be drilled by the customer by marking the positions of the holes on their original strip.
• Made to order; not covered by the Mimaki manufacturer’s warranty.

Function

• To provide the encoder sensor with the position reference of the carriage on the Y-axis
• Ensure synchronisation between the carriage’s movement and the print heads’ operation
• Ensure alignment of the forward and return passes
• Maintain the dimensional accuracy of the prints

Possible symptoms of wear

• ‘Y current over’ error or carriage stoppage during printing
• Misalignment or duplication of passes in bidirectional mode
• Fine, irregular stripes across the width of the media
• Scratches, ink marks or faded graduations visible on the tape

Replacing the encoder belt restores reliable carriage positioning and eliminates registration errors caused by impaired reading.
