INSTALLATION 19 September 1994
4.2.5 Replace ROMs and reassemble the machine
1. Replace the ROM (IC303) on the IPU board.
2. Replace the ROM (IC309) on the IPU board.
3. Replace the ROM (IC509) on the main board.
4. Replace the ROM (IC522) on the main board.
5. Re-assemble the machine.
4.2.6 Connect to the Fiery and adjust the printer gamma
The printer gamma must be adjusted for both Fiery print mode settings (halftone and contone).
1. Connect the Fiery controller to the controller interface connector with the cable provided from EFI.
2. First turn on the copier. When the copier in standing by, turn on the Fiery controller.
3. Watch the Fiery boot up. When "Press ESC to run Fiery Setup" is displayed, press the ESC key.
4. Press Enter until the "Enable halftone printing" setting is displayed. Then select Yes with the "
" key and press Enter.
5. When the "Default print mode" setting is displayed, select halftone.
6. Press Enter until "Save changes: No/Yes/Quit" is displayed.
7. If you changed either of the settings in steps 4 and 5, select Yes then press Enter. Otherwise, select Quit then press Enter. The Fiery continues its startup routine.
NOTE: If you made a mistake during set-up, select No and do the set-up
all over again.
8. When the Fiery controller enters idle mode, press the F4 key to print a test page.

9. Compare the color scales on the test page just printed with the color scales for halftone in the halftone area of the reference Fiery test chart. Check the following points on the print out.
1). The 16th levels in each of the 16-grade color test strips (YMCK) are similar in density to those on the test chart.
2). The 16th level in the 16-grades "PK" (Process Black) scale is similar to that on the test chart.
10. If the colors on the test page are not acceptable, adjust the data as follows.
1). Enter the SP mode on the copier.
2). Select "8: Printer".
3). In the "=Letter=" screens (pages 1 and 2) of the SP mode, adjust the 16th levels for the colors that need adjusting by changing only the IDMAX setting in the OFFSET column.
NOTE: The IDMAX OFFSET setting should be between 0 and 4.
Do not change the data in the STEP columns; these must remain at the default settings. Do not change the H, M, or L settings in the OFFSET column. Such changes will have no effect on the printout, because the various colors in the H, M, and L ranges are produced by dithering (the laser is switched on and off to produce dither patterns).
4). Exit the SP mode and press the F4 key on the Fiery keyboard.

11. If necessary, repeat the adjustment from step 9. Otherwise, go to step 12.
12. After your adjustment, reboot the Fiery controller to change the printer mode setting (press Alt-X or the Reset button).
13. Press ESC to enter Fiery Setup and select contone in the "Default print mode" (refer to steps 3 ~ 7).
14. When the Fiery controller enters idle mode, press the F4 key to print a test page.
15. Compare the color scales on the test page just printed with the color scales for contone in the contone area of the reference Fiery test chart. Check the following points on the print out.
1). The various grades along the color scales are similar in density to those on the reference test chart.
2). The gray balance of the "PK" test strip is similar to that of the reference chart.
16. If the color scales on the test page are not acceptable, adjust the
γ
correction data as follows.
1). Enter the SP mode on the copier.
2). Select "8: Printer".
3). In the "=Photo=" screens (pages 3 and 4), adjust the color scales by changing the
γ data in the OFFSET columns.
Low: Use to adjust levels 1 to 3 of the 16-grade scale. Middle: Use to adjust levels 2 to 14. High: Use to adjust levels 13 to 15. ID MAX: Use to adjust the whole range, including level 16.
Do not change this unless the whole range needs to be made brighter or darker. The adjustment is very sensitive, so it is best not to change the default settings.
Do not change the
γ data in the STEP column from the default
settings.
4). Exit the SP Mode and press the F4 key on the Fiery’s keyboard.
