Service mode. 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 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 printer 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

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.

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. Because 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 six-day grace period is built into the date system.
