cannon ir2000 copier

I want to put my canon ir 2200 copier on the network so that It caN SERVE AS AS NETWORKED PRINTER BECAUSE IT HAS GOT THIS OPTION . FIRST I INSTALLED THE NETWORK ADAPTER THAT CAME TOGETHET WITH THE COPIER AND THEN I ASSIGNED IP ADRESS TO THE ADAPTER AND I MAGED TO PING OTHER COMPUTERS ON THE NETWORK FROM THAT COPIER AND VICE VERSA THEN AFTER I FOLLOWED THE INSTALLATION INSTRUCTION AS ON THE MANUAL AND CREATE A NEW PORT . AND AFTER I TRIED TO PRINT A TEST PAGE BUT AFTER A FEW MINUTES I GOT THE MESSAGE THAT THE COMPUTER FAILED TO THE PRINTER BUT WHEN I PING THE COPIER IT RESPONDS WITHOUT AN ERROR SO WHAT MIGHT BE THE PROBLEM.
PLEASE HELP
