E300348 - Linear Encoder Scale 1857 (encoder tape)

Linear encoder scale – Mimaki JV33-130 / JV3-130 / CJV30-130 – E300348

The Mimaki E300348 linear encoder scale (Linear Encoder Scale 1857) is the optical scale fitted along the Y-bar of the 130 cm machines in the JV3, JV22, JV33 and CJV30 series. 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 for each pass. This precision ensures accurate drop placement and bidirectional printing without misalignment.

Supplied on its own, in the original dimensions of 1857 × 15 mm, including mounting holes. Three options are available on this product page: New (original Mimaki part), Refurbished (inspected original 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 1857 mm.
• Mounting holes drilled by DG Spare Parts using the original template: the strip is supplied ready for fitting.
• Same resolution and width as the original part, compatible with the existing encoder sensor.
• Made to order; does not carry the Mimaki manufacturer’s warranty.

Function

• To provide the encoder sensor with the carriage’s position reference 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 in the event of wear

• ‘Y current over’ error or carriage stopping during printing
• Misalignment or duplication of passes in bidirectional mode
• Fine, irregular streaks 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.
