Other features of the invention will be apparent from the following detailed description of the invention and the appended claims. Referring now to FIG. 1, there is shown a printing press unit (generally designated by 10) for printing an image on a paper web 14. The unit 10 comprises a plurality of print couples 28, 30, 32 for printing different colors of ink on the web 10.
34. As shown, 4-color printing unit 1
0, printing unit 28 can print cyan C ink, printing unit 30 can print magenta M ink, printing unit 32 can print yellow Y ink, and printing unit 34 can print black K ink. Can be printed.

Each printing unit 28, 30, 32, 34 has a plurality of printing rolls or cylinders 36 associated with a blanket cylinder or roll 40.
During printing by the unit 10, an image of the ink is transferred from the printing roll 36 to the associated rubber roll 40, printing the image on one surface of the web 14. Also, the unit 10
Has a plurality of print couples with a plurality of rubber rolls opposite the web 14 or a plurality of print rolls 38 associated with a blanket cylinder 42 to print the ink image.
To a rubber roll 42 to print an image on the other surface of the web 14. The following description of the print roll,
It is equally applicable to the printing rolls 36, 38 on both sides of the web 14. As shown in FIG. 2, the printing machine 10 includes a COMM,
MAC, LINK A, LINK B, DRIKE
It has a control unit (generally designated by the reference numeral 50) with a plurality of microprocessors 52 named C and LINK D, each microprocessor 52 being a printer 10.
Control different parts of. Each microprocessor 52 has a port 54 that communicates with each separate microprocessor 52.
And the microprocessors 52 communicate with each other.

Shown is a computer 56 (eg, a laptop or notebook computer) with a suitable memory and a display 58 for displaying the information, which computer 56 is a printer 60 for printing the information. Is equipped with. The computer 56 has in its memory a diagnostic device 62 which, during the initial assembly of the printing press 10, controls the control device 50 and the printing press 1.
Perform a 0 test. The diagnostic device 62 is a computer 56.
Can be connected to the port 54 of any microprocessor 52 to test the controller 50. Referring to FIG. 3, after the diagnostic program is started, the computer 56 displays information about the tests to be performed on the controller 50 of the computer 56. If the test is not selected by the operator, the program exits the program routine.

If the test is selected, the computer 5
6 displays information on the computer display 58 on how the selected test was performed or prints this information as a report by the printer 60. 2 for the test
There are two formats. In the first form, feedback is provided to signal to the program that the test was successfully completed, and in the second form no such feedback is provided to computer 56, in which case computer 56 Exit the program routine. If the test does not complete, the program enters a delay and checks again whether the test is complete. When the test is complete, the program displays or prints this result and enters the exit from the program routine.

Some sample screens are shown in FIG. The top row shows some tests that can be selected, along with a pop-up display to inform the operator. The bottom row shows another selectable test, and some feedback-type tests display the pass / fail status of that test. Actually done 1
One test is shown and the other is displayed as pending, not yet run. In each case, the program exits the routine after completion of the test. Also, monitor the diagnostic device for other tests selected. It is also possible to provide the computer 56 with information about the current state of the printing press 10, such as printing press parts that are not present when the test is selected, in which case the program will cause the printing press 1 to
Take into account the current status of receiving information about 0.

Therefore, according to the invention, the control device of the printing press comprises a diagnostic device in the form of a computer used by the operator when assembling a new printing press at the user's site. The diagnostic device of the present invention facilitates assembly of the printing press and can also be used to train newcomers in the assembly of the printing press. It should be understood that the above description of the present invention is provided for clarity of understanding only and is not in any way limiting. Various modifications will be apparent to those skilled in the art.
