If your printer is flashing maintenance errors, you can often fix it yourself using the Adjustment Program Pre-Setup Checklist Disable Antivirus

The L14150 is unique. It prints up to A3+ (13” x 19”), handles thick paper up to 256gsm, and features a 250-sheet dual tray. It’s designed for small offices and graphic designers.
