E300473 - Linear Encoder Scale 2349 (encoder strip)

Linear encoder scale – Mimaki JV4-160 / JV5-130S / TX2-1600 – E300473

The Mimaki E300473 linear encoder scale (Linear Encoder Scale 2349) is the optical scale mounted along the Y-bar of the JV4-160, JV5-130S and TX2-1600. It replaces the previous part numbers E300289 (JV4-160) and E300302 (JV5-130S). The encoder sensor continuously reads it to determine the exact position of the print heads.

Its graduations at 180 lines per inch (180 LPI) provide the controller with the position reference at each pass. This precision ensures accurate drop placement and bidirectional printing without misalignment.

Supplied on its own, in the original dimensions of 2337 × 15 mm, including mounting holes. Three options are available on this product page: New (genuine Mimaki part), Refurbished (inspected genuine part) or New / Compatible (strip manufactured by DG Spare Parts).

‘New / Compatible’ version – manufactured by DG Spare Parts

• Strip cut in our workshop from a generic 180 LPI encoder strip, 15 mm wide, to the original length of 2,337 mm.
• Supplied without mounting holes: these must be drilled by the customer by marking out the position of the holes on their original strip.
• Same resolution and width as the original part, compatible with the existing encoder sensor.
• 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.
