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.
Reset serial number
Use the service menu to reset the product serial number. See
Service mode functions on page 259.
Reset page counts
The page count that is stored in NVRAM and printed on the configuration page represents the number
of pages that the formatter has formatted (not including engine-test prints). If you install a new formatter
when repairing a product, use this menu item to reset the page count to the previous value. In this way,
the page count reflects the number of pages that the engine has printed rather than restarting the count
for the new formatter.
Use the service menu item TOTAL PAGE COUNT to reset the product page counts. See
Service mode
functions on page 259.
Product cold reset
A cold reset unlocks menus that have been previously locked and sets all control panel menu items
(including EIO settings) back to the factory defaults. However, it does not clear the values in the
Service
mode functions on page 259 menu (such as the serial number and page counts).
NOTE: Before performing a cold reset, print a menu map and a configuration page. Use the information
on the configuration page to reset any customer-set product configuration values that the cold reset
procedure changes.
1. Turn the product off.
2. Turn the product on. When the memory count begins, press and hold the OK button. Continue
holding down the OK button until all three product control-panel lights flash once and then remain
on. This might take up to 10 seconds.
3. After the message SELECT LANGUAGE appears on the display, press the
button or the
button until COLD RESET is highlighted.
4. Press the OK button. The product performs a cold reset and then continues its power-on sequence.
5. Check all I/O settings and reset any customer-set product configuration values.
