HP CP4525DN Laser CC494A#ABA manual Service ID, Cold Reset Paper, NEW Registration Roller

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.
