Thank you for contacting BCH Technologies. We apologize for the delayed reply. Printer problems are urgent, and we want to give you a careful, detailed answer. Thank you for supporting BCH and our YouTube channel.
The HP 803 black cartridge has an integrated printhead, but that alone does not confirm that the sponge-removal and drilling method in this HP 61–68 video applies to it. The 803 is used in regional printer markets, and an apparent cartridge-family similarity does not establish that its shell, ink path, vent, contacts, or chip will tolerate the same modification. We have not confirmed a safe HP 803-specific conversion from the information supplied.
Before opening or drilling the cartridge, check the exact printer model, the full cartridge label or part number, and the country where the printer was sold. Compare those details with an HP 803-specific kit and instructions, if available. Do not rely on a kit labeled only for HP 61–68. Drilling in the wrong place can damage an internal ink passage, cause leaks or poor venting, and leave an integrated printhead unusable. Keep ink away from electrical contacts, and do not force a cartridge into a printer to test an uncertain fit.
If a cartridge has already been modified and now leaks, is not recognized, or prints poorly, stop and have the cartridge and printer checked before repeated cleaning or further drilling. A cartridge replacement may be safer than further modification; a printer-board fault is not established by this question. Ask a qualified technician to diagnose the printer if a known-compatible cartridge also fails.
