NOTE: Before performing a NVRAM initialization, print a menu map and a configuration page. Use
the information on the configuration page to reset any customer-set product configuration values that
the NVRAM initialization procedure changes. Take special not of the page count, service ID, and the
serial number.

Service ID
Use this item to show the date that the product was first used on the control panel. This eliminates the
need for users to keep paper receipts for proof of warranty.
Because the product does not have an internal clock, the availability of the service ID date depends on
the product being connected to a source that can provide the date, in this case a time server on the
same network as the product. When the product is not connected to a date source, the service ID is not
available, and 00000 appears on the configuration page.
Restore service ID
If you replace the formatter, the date is lost. Use this menu item to reset the date to the original date
that the product was first used. The date format is YYDDD. Use the following formula to calculate the
dates:
1. To calculate YY, subtract 1990 from the calendar year. For instance, if the product was first used
in 2002, calculate YY as follows: 2002 - 1990 = 12. YY = 12.
2. Subtract 1 from 10 (October is the tenth month of the year): 10 - 1 = 9.
Multiply 9 by 30: 9 x 30 = 270.
-or-
Add 17 to 270: 270 + 17 = 287. Thus, DDD = 287.
Convert the service ID to an actual date
You can use the product service ID number to determine whether the product is still under warranty.
Use the following formula to convert the service ID into the installation date as follows:
1. Add 1990 to YY to get the actual year that the product was installed.
2. Divide DDD by 30. If there is a remainder, add 1 to the result. This is the month.
3. The remainder from the calculation in step 2 is the date.
