OKI C610 用户手册

If a sheet is well advanced out of the top of the printer, 

simply grip it and pull gently to draw it fully out. If it does 

not remove easily, do not use excessive force. It can be 

removed from the rear later.

Press the cover release and open the printer’s top cover fully.

Note:
For illustrative purposes, the C711 printer has been 

shown. If you have a C610 printer, the principle is the 

same with any exceptions noted.
