Service ID
This information appears on the configuration page, which eliminates the need for customers to keep
paper receipts for proof of the warranty. Because the MFP does not have an internal clock, the
availability of the service ID date depends on the MFP being connected to a source that can provide
the date, in this case a time server that is on the same network as the MFP. When the MFP is not
connected to a date source, the service ID is not available, and 00000 appears on the configuration
page.
Restoring the Service ID
If you replace the formatter, the date is lost. Use this menu item to reset the value to the date that the
MFP was first used. The date format is YYDDD. Use the following procedure to calculate the date.
1 To calculate YY, subtract 1990 from the calendar year. For instance, if the MFP was first used in
2002, calculate YY as follows: 2002 – 1990 = 12 (YY = 12).
2 To calculate DDD, use the following formula: 30 (calendar month – 1) + calendar day = DDD. If
the calendar day is 31, use 30 instead. For instance, if the MFP was first used on October 17,
calculate DDD as follows:
a Subtract 1 from 10 (October is the tenth month of the year): 10 – 1 = 9.
b Multiply 9 by 30: 9 x 30 = 270.
c Add 17 to 270: 270 + 17 = 287 (DDD = 287).
Converting the service ID to an actual date
You can use the MFP Service ID number to determine whether the MFP is still under warranty. Use
the following procedure to convert the Service ID into the installation date.
1 Add 1990 to YY to determine the actual year that the MFP was installed.
2 Divide DDD by 30, and add 1 to the whole-number part of the quotient. The total is the month.
3 The remainder from the calculation in step 2 is the day of the month.
Using the Service ID 12287 as an example, the date conversion is as follows:
1 12 + 1990 = 2002, so the year is 2002.
2 287 divided by 30 = 9 with a remainder of 17. Add 1 to 9 to get 10, so the month is October.
3 The remainder (from the above calculation) is 17, so that is the day of the month.
4 The complete date is 17-October-2002.
