If your Epson printer not printing black, it may be due to clogged printhead nozzles, low or dried ink cartridges, or incorrect print settings. Running the printer’s nozzle check and head cleaning from the Epson software can help fix it. Also, ensure genuine Epson ink is used and cartridges are properly installed. Updating drivers and performing regular maintenance can prevent the Epson printer not printing black issue and restore sharp, clear black prints easily.
