If your Oki printer needs paper, the ALARM light is not ON, and you can't load paper: 1. Press and release the SEL key. 2. Press and hold the SHIFT key and press the RESET/CHARACTER PITCH key. The ALARM light should illuminate, allowing you to load paper.
Why do word processor files not print the way I have the menu and front panel set on my Oki ML5520?
Settings in your software application can override settings in your printer driver, and your printer driver settings can override any settings from the printer menu or printer front panel. Many word processors send an “initialisation string” or an I-Prime signal to the printer before sending a file, which can override panel and menu settings. To make your Oki printer ignore the reset code, enter the Menu Mode, go to the Set-Up group, and change the setting for Reset Inhibit to YES. To eliminate I-Prime signal issues, enter the Menu Mode, go to the Parallel Interface group, and change the setting for I-Prime to Invalid.
Why does ink smear on the paper when I print narrow columns with my Oki ML5520?
Ink smears on paper when printing narrow columns on your Oki printer may be due to excessive printhead travel from the centering position. To resolve this, enter the Menu and set the Centering Position to MODE 1. If MODE 1 doesn't work for the wide-carriage printer, try setting the Centering Position to MODE 2.
Why is the printing smeared and streaked after I installed a new ribbon in my Oki Printer?
