You probably need a new drum (not included with the toner cartridge). When the drum assembly is used up the machine will print one page and then stop. If you open the cover and close you will get a second page.
The only way to truely know if the drum is used up is to connect to the printer via a parallel connection and then run a program that is on the driver CD. Then you will get a readout of the drum life. Details are on the Oki web page.
This was exactly the problem we encountered with our B4250. I believe you will also have a flashing indicator light on the top panel that doesn't seem to make sense. It will clear along with the problem when you change the drum.
Good Luck!

Re: waiting your help
Your printer does not have a display to let you know what's wrong with it. To check the unit, you must install the Printer Monitor software that came with the unit. Your problem most probably refers to empty toner or drum replacement.

The LED array probably needs cleaning. This is located on the lid that you open when changing the drum/toner and is a dark coloured bar going left-right across the lid. Clean this with a cloth. Also check the opening in the drum where you can see the green cylinder from the top for any small obstructions and remove if necessary. Any obstructions or dirt on the LED will line up with the print defect on the page and should be easy to remove. Be careful not to damage the green cylinder.
delete everything printer related. ie. printer, status monitor, and try to print a test page via the button, I think you have to hold it down for ten seconds. I could be wrong though.
You have accidentally pulled the back paper tray. Even when pulled a little, this tray tells the printer to deliver output to the back. This is useful when printing on heavy, or thick paper. Just push it back all the way down to it's original place.
my installation CD is not working.I cant open it.
