We have an HP Color Lasersjet CM 2320nf MFP all-in-one printer. Roughly 25% of our prints have horizontal lines of ink across the page. The horizontal lines print in all 4 colors. I have tried to calibrate, cleaning mode, cleaned the drums and replaced all cartridges but nothing is changing. I tried to chat with HP but the printer is out of warranty. Is there anything I can do to solve this????
I have attached a scanned page with the problem...
