Restore the service ID
Restore the service ID
When replacing the formatter, the date is lost. Use this menu item to reset the date to the original date that
the printer was rst 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 printer was rst 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
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 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.
