Send the printer model, old part photos, part label, connector photo, dimensions and installed position if you are not fully sure. For boards, cables, motors, encoder parts and pumps, visual similarity alone is not enough to confirm compatibility.
Install with a trained technician. After replacement, check carriage movement, media feed, ink pump operation, capping seal, cable seating or sensor alignment according to the part type before production use.
