The method of accessing a print cylinder in a box making machine having a generally horizontal path of conveyance and at least one work station positioned along said path and including a work means for engaging and operating on boards conveyed along said path, said work means including a printing mechanism including a print cylinder which prints bottom surfaces of the boards, and an impression cylinder overlying the print cylinder, and transfer means engageable with the boards to move the boards along said path of conveyance to said work station;

• the method comprising mounting said transfer means and said impression cylinder for vertical movement between an operative position adjacent said path of conveyance for transferring boards along said path, and an inoperative position substantially spaced away from said print cylinder to provide user access to said print cylinder for maintenance or replacement of said print cylinder, moving the transfer means and the impression cylinder to said inoperative position thereby providing sufficient space between the transfer means and said print cylinder to access into the space to service or replace print plates on the print cylinder, and accessing said space and engaging said print cylinder to service or replace print plates on the print cylinder while the transfer means and impression cylinder are in said inoperative position.
