Restore the Service ID
When replacing the formatter, the Service ID date is lost. Use this menu item to reset the date to the original date that the printer was first first used. The date format is YYDDD. Use the following formula to calculate the Service ID.
Calculate the service ID
For the calculation below, the placed-in-service date is 17OCT2002.

1. To calculate YY, subtract 1990 from the calendar year. If the printer was first first used in 2002, calculate YY as follows: 2002 - 1990 = 19. 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 and add 17 to 270: 270 + 17 = 287. Thus, DDD = 287.
3. In this example the Service ID is 12287.

Use the printer Service ID number to determine whether the printer is still under warranty. Use the following formula to convert the Service ID into the actual date the printer was placed-in-service. For the example below, use the Service ID previously calculated (12287).

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.
   a. 12 + 1990 = 2002, so the year is 2002.
   b. 287 divided by 30 = 9 with a remainder of 17. Because there is a remainder, add 1 to 9 to get 10, which represents October.
   c. The remainder in step 2 is 17, so that is the date. The complete date is 17-October-2002.
   NOTE:A six-day grace period is built into the date system.
