First, make sure that paper feed switch is set accordingly to the paper path you are using (rear feed, bottom feed or friction). If you make a change, turn the unit off and on.

If it is set correctly, there might be an obstruction on the printer top cover that interferes with the cover sensors. This forces the printer to think that the lid is still open and will signal it as you have described.

The last option will be a damage to the sensors or to the mainboard. This is rare, but if the case, you need a repair center.

Be blessed.

How do i identify the font settings set in my printer

Your printer is designed to change font and pitch from the front panel. Just press the SEL/MENU button to take the printer offline. Then press the PRINT QUALITY button (to the right side of the panel) to make the lights switch to different fonts. Finally, press SEL/MENU to activate the changes and return the printer to online status. Be advised, these changes will not be permanent. To make a change permanent, you need to read the user's manual which I can email to you. Finally know that Windows does not pay attention to these settings, they are only goog in text applications such as DOS.

Oki microline 520

It is likely that a few different things can cause this condition. First suggest looking for the paper present sensor. This is usually an optical sensor with a lever which contacts the paper. If the lever is broken, or sensor defective, an error condition is exhibited, and printer won't operate. There is also a sensor for printhead home position, and perhaps one or more sensors at one end of the platen assembly. Some printers sense whether a lever is set for tractor feed style paper, or for standard single sheet. A NEC p6200 has one, and probably other printers too. Check for the presence and proper operation of these. You might have to remove a cover to see them... As you probably know, dot matrix printers are practically dinosaurs these days. You should be able to pick up a decent Epson or other good model for practically nothing, if diagnosis on your rig is fruitless. Companies began getting rid of these critters years ago.
