Service menu
This section provides information about accessing the service menu and its operation.
Accessing the Service menu
The Service menu is PIN protected for added security. Only authorized service people have
access to the Service menu. When you select SERVICE from the list of menus, you are
prompted to enter your 8-digit PIN number. The PIN for the HP Color LaserJet 3500/3550
series printer is 10350003 and for the HP Color LaserJet 3700 series printer is 10370003.
1. Press
or until the first digit of the PIN is displayed.
2. Press
to save the digit. The display will replace the digit with an asterisk.
3. Repeat steps 1 and 2 until all eight digits are entered.
4. Press
at any time to move to the previous digit.
Clear event log
This item allows you to clear the printer’s internal event log.
Total page count
The page count 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 printer, use this menu item to reset the page count
to the previous value. In this way, the page count reflects the number of pages printed by the
engine rather than starting over for the new formatter. The page count is broken into two
categories: total mono pages and total color pages.
Transfer kit count
This value can be changed in the service menu but it will not change the value of the
transfer kit. This value is initially set to zero at the factory. This value is automatically reset to
zero when a customer installs a new transfer kit and sets NEW TRANSFER KIT to YES in
the Resets menu.
If only the formatter is replaced, the transfer kit page count will not be lost.
Fuser kit count
This item allows you to reset the fuser count if the value is lost, such as when you replace
the formatter. This value is initially set to zero at the factory. Enter a value up to 60,000 for
the hp 3500 and 75,000 for the HP 3700/3550. This value is automatically reset to zero
when a customer installs a new transfer kit and sets NEW FUSER KIT to YES in the Resets
menu.
Serial number
If you replace the formatter, use this item to reset the serial number of the printer.
