Review on 🖨️ HP 934XL Black Ink Cartridge: Compatibility with HP OfficeJet 6800 & Pro 6230 Series (C2P23AN) by Mark Howard

I bought this product, 934xl for my printer. The packaging was previously opened and sealed with tape. The cartridge has already been used. When I installed it it was mostly full and looking like a genuine HP product and I needed to print important documents. However, after a few uses, my printer showed a printhead error message and stopped printing. I have never had any problems with this printer. It doesn't even respond when I try to clean the printheads as part of printer maintenance. I even tried cleaning the printheads with a cleaning kit but it still doesn't work. When I looked into this issue, I found that it could be caused by excessive ink leakage. In the future I will shop at Officedepot, Staples or another retail store to make sure I get a quality product that won't ruin my printer.
