HP 1600 - Manual (Page 94)

A Software Update button is also available from this dialog box. When you click Software Update, the
driver opens your Web browser and connects you to the HP support Web site to update your HP Color
LaserJet 1600 printing-system software.
Page count
The page count is initialized at zero during installation, and every page that the driver prints should
update the count by one. When the driver is reinstalled, the customer can reset the page count to zero.
The page count is expressed as Page Count: NNNNNN, where N is a six-digit decimal representation
of the number of pages that have been printed.
Service ID (Born-on date)
The service ID (born-on date) is the date on which the HP Color LaserJet 1600 print driver was installed.
The number tells HP how long the customer has been using the printer. The customer can reset the
date by reinstalling the driver.
The service ID is expressed as Service ID: YYDDD, where YY is a decimal representation of the current
year minus 1990, and DDD is (calendar month minus 1) multiplied by 30 plus the calendar date (or 30
if the date is 31).
The Service ID is stored in the registry.
How to calculate the Service ID from a calendar date
1. YY = calendar year minus 1990
Examples:
1998 = 1998 minus 1990 = 08
2001 = 2001 minus 1990 = 11
2. DDD = (calendar month minus 1) times 30 plus calendar date (or 30 if the date is 31)
Examples:
October 10 = 9 times 30 plus 10 = 280
December 31 = 11 times 30 plus 30 = 360
How to convert the Service ID into a calendar date
1. Year = YY plus 1990
Examples:
YY = 08, then year = 08 plus 1990 = 1998
YY = 11, then year = 11 plus 1990 = 2001
2. Date = DDD divided by 30 (plus one if a remainder results) = the month. The remainder is the date.
If the remainder is 0, then the date is 30.
Examples:
DDD = 280, then 280 divided by 30 = 9 with a remainder of 10
