Service ID
When printing from an HP Color LaserJet 3000/3600/3800/CP3505 Series printer, this information appears on the configuration page, which eliminates the need for customers to keep paper receipts for proof of the warranty. Because the printer has an internal clock, the availability of the service ID date depends on the printer being connected to a source that can provide the date, in this case a time server that is on the same network as the printer. When the printer is not connected to a date source, the service
ID is not available, and 00000 appears on the configuration page.
Converting the Service ID to an actual date
You can use the printer Service ID number to determine whether the printer 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 printer was installed.
2.
Divide DDD by 30 (and, if there is a remainder, add 1 to the quotient) to determine the month the printer was installed.
3.
The remainder from the calculation in step 2 is the day of the month. If no remainder resulted from the calculation in step 2, then the day of the month is the 30th.
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.
A 6-day grace period is built into the date system.
Restoring the Service ID
If you replace the formatter, the Service ID is lost and must be restored. Use this menu item to reset the
Service ID, which is calculated based on the date the printer was first used. The date format is YYDDD.
Use the following procedure to calculate the Service ID.
1.
To calculate YY, subtract 1990 from the calendar year.
2.
To calculate DDD, use the following formula: 30 * (calendar month – 1) + calendar day = DDD. (If the calendar day is 31, use 30 instead.)
Using October 17, 2002, as the date the printer was first used, the service ID conversion is as follows:
a.
2002 minus 1990 = 12, so YY = 12.
b.
10 minus 1 (calendar month minus 1) = 9.
c.
9 times 30 = 270.
d.
270 plus 17 (the calendar day) = 287, so DDD = 287.
e.
The complete service ID number is 12287.
