HP Pro 4300 C9H70UT C9H70UT#ABA manual Restoring the Service ID

Service ID

This information appears on the configuration page (see “Configuration page” on page 241), which eliminates the need for customers to keep paper receipts for proof of the warranty. Because the printer does not have 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 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.

Restoring the Service ID

If you replace the formatter, the date is lost. Use this menu item to reset the value to the date that the printer was first used. The date format is YYDDD. Use the following procedure to calculate the date.

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.To calculate DDD, use the following formula:

30 (calendar month – 1) + calendar day = DDD. If the calendar day is 31, use 30 instead. For instance, if the printer was first used on October 17, calculate DDD as follows:

a.Subtract 1 from 10 (October is the tenth month of the year): 10 – 1 = 9.

b.Multiply 9 by 30: 9 x 30 = 270.

c.Add 17 to 270: 270 + 17 = 287 (DDD = 287).

Converting the Service ID to an actual date

You can use the printer’s 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 add 1 to the remainder. The total is the month.

3.The remainder from the calculation in step 2 is the day of the month. Using the Service ID 12287 as an example, the date conversion is as follows:

●12 + 1990 = 2002, so the year is 2002.

●287 divided by 30 = 9 with a remainder of 17. Add 1 to 9 to get 10 so the month is October.

●The remainder (from the above calculation) is 17, so that is the day of the month.

●The complete date is 17-October-2002.

A 6-day grace period is built into the date system.
