Original Roland Wiper Blade Matte for EJ640

Function In The Maintenance Station

• The wiper removes excess ink, dust, and residue from the nozzle surface during cleaning cycles.
• A stable wiper helps reduce mist buildup and supports better daily nozzle condition.
• It is a regular maintenance item and should be replaced when the edge hardens, bends, swells, or no longer wipes cleanly.

Recommended Printing Environment

• Referenced machine models: EJ640, EJ-640.
• Suitable for industrial inkjet printer maintenance when the blade size and holder structure match the model-reference part.
• Useful for buyers who want to reduce poor wiping, excess ink residue, or unstable cleaning results around the printhead area.

Replacement Notes

• Check blade shape, width, holder style, and model-reference part reference before purchase.
• Many buyers replace wipers together with cap tops, cap pads, or waste sponges to restore maintenance-station performance.
• If the printer shows nozzle contamination, dragging ink, or repeated cleaning issues, inspect the wiper first.

Typical Service Symptoms

• Replace the wiper when the nozzle plate stays dirty after cleaning, ink starts dragging, or residue builds up near the printhead face.
• A hardened, curled, or swollen blade can reduce wiping quality and make normal cleaning cycles less effective.
• If the printer needs frequent cleanings to recover nozzle condition, the wiper should be inspected early in the maintenance process.

Fitment Checklist

• Referenced machine models: EJ640, EJ-640.
• Match blade profile, width, mounting style, and glossy or matte version where applicable.
• Compare the old wiper directly if the machine family uses multiple holder or maintenance-station revisions.

Maintenance Pairing Suggestions

• Buyers often replace the wiper together with cap tops, cap pads, flush sponges, or waste-ink absorbers.
• Use this maintenance part only when the blade material is suitable for your industrial inkjet printer environment.
• After installation, run a cleaning cycle and inspect whether the nozzle surface is being wiped evenly.
