Key Details

Why Buyers Choose This Product

• Ink type reference: Industrial inkjet
• Supports buyers who need replacement ink matched to the correct series and print environment
• Suitable for production workflows that prioritize stable jetting and predictable daily output

Buying Notes

• Match the ink series or maintenance-fluid type with the reference cartridge, bag, or bottle specification used by your printer.
• If you are replacing fluid for a specific head family, double-check the supported heads: DX7.
• Color, packaging format, and regional version should be confirmed before shipment.

Use Position & Maintenance Role

• This maintenance pad or absorber is typically installed in the capping or waste-ink area to absorb ink, support sealing, or keep the maintenance station cleaner.
• A healthy pad helps maintain cleaner maintenance cycles and more stable printhead care.
• Saturated, hardened, or contaminated pads should be replaced to avoid poor sealing or unstable cleaning results.

Compatibility Reference

• Referenced machine models: EJ640.
• Referenced printheads: DX7.
• Match the part shape, dimensions, and maintenance-station position with the reference component.

Recommended Replacement Timing

• Replace when the pad is ink-saturated, deformed, torn, or no longer supports clean maintenance cycles.
• Many buyers replace pads together with cap tops, wipers, or other maintenance-station consumables.
• If the machine shows poor capping, excess ink buildup, or inconsistent cleaning performance, inspect this item first.
