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, the product prompts you to enter an eight-digit PIN number. The PINs for the HP Color LaserJet Enterprise CP4020-CP4520 Series are 11402509 and 11452509.

1.Press the Home button.

2.Press the down arrow to highlight SERVICE, and then press the OK button.

3.Enter the eight-digit PIN using the alphanumeric keypad.

4.Press the OK button to enter the PIN and open the SERVICE menu.

The following menu items appear in the SERVICE menu:

CLEAR EVENT LOG	This menu item allows you to clear the event log.
CLEAR BOOTLOADER PASSWORD	This menu item allows you to clear the bootloader password if
	it has been lost.
TOTAL PAGE COUNT	The page count stored in NVRAM and displayed on the
	configuration page represents the number of pages that the
	formatter has formatted (engine test prints are not included in
	this number). If it becomes necessary to repair a product by
	installing a DC controller PCA, you must set the page count so
	that it represents the age of the print engine rather than the age
	of the DC controller PCA. When you press either the up arrow
	or down arrow to change the value of the first digit, the
	prompts are changed to indicate an acceptable range and the
	appropriate value.
MONO CYCLE COUNT	After replacing the formatter, use this item to reset the mono
	page count so that the figure continues to represent the page
	count for the product engine. 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. The page count is in
	two categories: total mono pages and total color pages.
COLOR CYCLE COUNT	After replacing the formatter, use this item to reset the color
	page count so that the figure continues to represent the page
	count for the product engine. 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. The page count is in
	two categories: total mono pages and total color pages.
