1 Standardized Calibration Process for the imagepress C1 Series with Server Calibrations

2 Please read this disclosure before proceeding. The printer should be stabilized before performing the following adjustments. If the printer has not been operating for a period of time, it is recommended that at least 50 sheets of 11x17 images be printed before starting the adjustments. Determine if it is possible for your customer to manage jobs so that a non color critical job can be run before performing the following procedures. This should sufficiently stabilize the printer and reduce any additional cost to the Customer. In the RIP calibration process, step 16-23, CUSA suggests using the 21 sorted patches for the measurement page. Overall this should provide satisfactory image quality. If your customer is still not satisfied with the printer output using the 21 sorted, performing the calibration procedure using the 34 sorted or either of the randomized measurement pages may provide more satisfactory output.

5 1. Prepare a paper tray and place 11X17 paper in it. Paper type is not important in this step. 2. Enter Service Mode and go to Copier > Test. A. Properly enter the tray in PG-PICK that was selected in Step 1 and select OK. B. Select 2-Side and enter 1. Select OK. C. Select PG-QTY, enter 25 on the key pad and Select OK. A- B- C- 25

6 3. Select TYPE and from the key pad enter 16 and press OK and press the Start button. Let the printer run the 50 prints to refresh the starter in the developer housings.

8 4. From the Fiery Command WorkStation select Server then Manage Color.

9 5. Select Calibrator.

10 6. A. Select the Shading Correction tab. B. Select Measurement tool, in this example we chose the EFI Spectrometer ES C. Follow the procedure to Generate Measurement Page.( Procedure Performed at Printer UI) D. Click Measure. E. Message will appear. and select OK. A B -E C D

11 7. After clicking OK in previous step the dialogue box on the left will appear. If the Patches are scanned improperly the dialogue box on the right will appear. When scanning Test Page, scan from left to right, see picture below. Be sure to place 20 sheets of 28lb Hammermill 98 or 100 Brightness paper under your test page before scanning.

12 8. When the process is complete select OK, then Apply and Done. Complete Shading Correction at the Printer UI.

13 9. The following screen will appear on the Printer UI. Select Store and Finish. The Shading Correction Process is complete.

15 10. Select Additional Functions>Device Management Settings. Then select Auto Gradation Adjustment.

16 11. Select Auto Gradation Adjust Method.

17 12. Select Printer Only.

19 13. Set up a paper tray with Hammermill 28 lb and 98 or 100 Brightness. In Additional Settings go to Adjustment / Cleaning and select Auto Gradation Adjustment.

20 14. Select Full Adjust and follow the process.

21 15. Select the Tray loaded with 11x17 28 lb Hammermill (98 or 100) Brightness then select OK. Let the Full Adjust run to completion.

23 16. From the Fiery Command WorkStation select Server then Manage Color.

24 17. Select Calibrator.

25 18. A. Select Calibration. B. Select Expert. C. Choose the type of Spectrometer that is being used. In this example we are using the EFI Spectrometer ES Connect the device, the message will appear when the connection is made. D. Select Print. A B C D

26 19. For this demonstration we are using the 21 Sorted Patches Measurement Page (please see note). This will generate a Measurement Page. Select 2 copies. Then Select Print. Note: The 21 Sorted Patches Measurement page generally provides satisfactory color output. This may not be acceptable to all Customers. Therefore if a Customer is concerned about color output it is advisable to perform calibration choosing another Measurement page to determine if the output satisfies the Customers requirements.

27 20. Use the second test print from step 19. Slide the Spectrometer, from left to right, over the color gradation strips in the order shown on the screen shot on the left. Using the second print ensures that any residual image or defects are eliminated. Using the second test print from step 19, place Hammermill 28 lb (98 or 100) Brightness 11 X 17 paper under the pattern to ensure a pure white background when scanning.

28 21. If the Spectrometer is unable to read the correct number of patches on the color gradation strip the following red screen will appear. Just follow the directions on the red screen to proceed.

29 22. Once successful, all of the colored rectangles will have check marks and the screen will declare The measurement process was successful. Select OK.

30 23. Click Ok, then Apply and finally select Done. The Calibration Process is now completed.
