HP (Hewlett-Packard) CC490A All in One Printer User Manual


 
SERVICE ID Use this item to show the date that the product was first used
on the control panel. This eliminates the need for users to keep
paper receipts for proof of warranty.
Restore the service ID
If you replace the formatter, the date is lost. Use this menu item
to reset the date to the original date that the product was first
used. The date format is YYDDD. Use the following formula to
calculate the dates. The date 17-October-2002 is used as an
example.
1. To calculate YY, subtract 1990 from the calendar year.
For instance, if the product 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
You can use the product Service ID number to determine
whether the product 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 product
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. Since 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.
COLD RESET PAPER When you perform a cold reset, the paper size that is stored in
NVRAM is reset to the default factory setting. If you replace a
formatter board in a country/region that uses A4 as the
standard paper size, use this menu to reset the default paper
size to A4. LETTER and A4 are the only available values.
NEW REGISTRATION ROLLER Use after installing a new registration roller.
MEDIA SENSOR VALUE Use this menu item to calibrate the media sensor by selecting
a threshold value from a specified range. This calibration is
most likely to occur when a media sensor has been replaced,
but might also occur if the current sensor needs to be
optimized. The recommended media sensor threshold value
for each sensor is included in the replacement kit for the part.
