HP OfficeJet 7500A won't print black, printhead replaced already

[baseball26]

I have an HP OfficeJet 7500A All-In-One printer, accessed as a wireless device.  Recently the printer stopped printing black ink – the other colors still printed.  Here is what I have tried to do to fix the problem, but have been unsuccessful so far:

1. I cleaned the vent area on the top of the existing HP-manufactured black ink cartridge, which made no difference.
2. I then replaced the HP-manufactured black ink cartridge with a new one, which also made no difference.
3. I cleaned the printhead twice using the automatic method through the control panel, which did not fix the problem.
4. I removed the ink cartridges and printhead, and cleaned the printhead manually 3 times, according to instructions provided on the official Web site, “HP Customer Support – Knowledge Base”, https://support.hp.com/us-en/product/hp-officejet-7500a-wide-format-e-all-in-one-printer-series-e910..., “HP Officejet 7500A Wide Format Printers - Color or Black Ink Not Printing.”  This did not fix the problem – still no black ink printed.
5. I deleted the existing printer driver and installed an updated printer driver, which had no effect.
6. I ordered and installed a new printhead from HP, which has not fixed the problem so far.  After installation, the following error message appears, even after unplugging and restarting the printer several times:

Ink system has failed.  Unable to copy, receive faxes, or print.  Refer to printer documentation.  Error 0xc19a0041.

The printer will now not print at all.

If you have already performed the steps from the document  '0xc19a0005' or Similar Error Code Displays for the error, Color or Black Ink Not Printing for print quality and the issue persists, it could be a hardware failure.
