ENWW Service menu 437
Restoring the Service ID
If you replace the formatter, the date is lost. Use this menu item to reset the date to the original
date the printer was first used. The date format is YYDDD. Calculate the date as follows:
1 To calculate YY, subtract 1990 from the calendar year. For instance, if the printer 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 printer 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. Thus, DDD = 287.
Converting the Service ID to an actual date
You can use the printer’s Service ID number to determine whether the printer is still under
warranty. Convert the Service ID into the installation date as follows:
1 Add 1990 to YY to get the actual year that the printer 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.
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. Since there is a remainder, add 1 to 9 to get 10,
which represents October.
3 The remainder in step 2 is 17, so that is the date.
4 The complete date is 17-October-2002.
Note A 6-day grace period is built into the date system.
Cold reset paper
When you perform a cold reset, the paper size stored in NVRAM is reset to the default factory
setting. If you replace a formatter board in a country/region such as Europe that uses A4 as the
standard paper size, use this menu to reset the default paper size to A4. LETTER and A4 are the
only available values.
