Common Questions
Which ink can I use?
The manufacturer reference is aqueous. Confirm viscosity, waveform, temperature, pressure, and the full Kyocera KJ4B-0300 label before installation.
How do I confirm compatibility?
Send the printer model plus photos of the existing label, connector, cable, drive board, and ink setup. We will compare them before payment.
Can I install the printhead myself?
Professional installation is recommended. Inspect the label and condition before installing; contact us first if anything differs from the confirmed order.
Please confirm the product model, specifications, and compatibility before ordering. Except where required by applicable law, buyer-side compatibility mistakes generally require review and may not qualify for return, refund, exchange, or compensation.
Printheads, inks, cleaning liquids, electronic boards, and opened or installed items usually require written review before return unless we shipped the wrong item or the goods arrived damaged.
If your order arrives damaged or incorrect, contact us within 3 calendar days after delivery with photos, package details, and your order number so we can review the case.
