OF 9 Ink Stick Count Mismatch
Use this RAP when the number of ink sticks in the ink loader does not correspond with the per-
cent values shown on the UI display.
The NVRAM value is read by the software and processed internally. It is actually the approxi-
mate number of micrograms of ink left in the ink loader and is not a percentage. The percent-
age is computed by the software and updated by the IME software to the UI.
Procedure
Only perform this procedure when:
• There is more than one ink stick difference between the number of ink sticks in the ink
loader and the indicated value on the UI.
• If the NVM values have been corrupted.
Perform the following:
1. Remove the rear cover, PL 81.10 Item 1 .
2. Remove the ink loader access cover rear, PL 81.10 Item 7 .
3. Check the number of ink sticks in the loader.

8. Select Read. The NVM description and value will be displayed.
9. To calculate the new values which are nominal mass and measured in micrograms:
Black ink stick has a mass value = 204000000 micrograms.
Colour ink stick has a mass value = 189000000 micrograms
Count the number of complete ink sticks and estimate the size of the ink stick in the melt
plate assembly. Make the calculation using the mass values for each ink colour. Enter the
values in the NVM for each colour.
