EJ stands for "Electronic Journal" , it saves the epense of adding a printer just for the detail. Good bookkeeping procedures are to print, then clear the EJ each day and send this report with the moneys to the owner of the business. So, what one needs to do is print, then clear or just clear the EJ. Not knowing what model and make your using, I cannot speak to the exact steps but in you manual or by turning the control key one can find some instructions to do this procedure. Please let me know that this helps, as we are a SAM4 dealer.
