HP LaserJet 4101mfp Installation conditions, Media condition, Unit condition, Preliminary operating checks

	Preliminary operating checks
	Verify that the conditions in the following lists are met before troubleshooting a specific MFP
	problem.
	Installation conditions
	● The MFP is plugged in, and specified power is delivered.
Hint	The print unit and the scan unit have separate power cords and power receptacles. Verify that
	both of these cords are correctly installed and that the print unit’s power cord is connected to a
	working power receptacle. See “Back view” on page 21.
	● The MFP receives maintenance on a regular basis. See “Cleaning the product” on page 36.
	● The MFP is positioned on a solid, level surface.
	● The MFP is not exposed to direct sunlight.
	● The print unit is never exposed to ammonia fumes. See “General guidelines” on page 36.
	● The customer is using acceptable print media. See the HP LaserJet 4100 series printer
	service manual for printing specifications, or see the Print Media Guide for the HP LaserJet
	printer family for general requirements.
	● The scanner-carriage lock is in the unlocked position. See “Front view” on page 20.
	● The cable from the ADF is securely fastened to the connector on the scanner-controller
	assembly. See “Back view” on page 21.
	● The line voltage does not vary more than 10 percent from the nominal rated value specified
	on the power-rating label. See the HP LaserJet 4100 series printer service manual for
	environmental specifications.
	● The operating environment for the MFP is within the temperature and humidity
	specifications. See the HP LaserJet 4100 series printer service manual for environmental
	specifications.
	● Non-HP components (such as refilled print cartridges, font DIMMs, and memory DIMMs) are
	removed from the MFP.
Note	Sudden changes in MFP environment can cause image defects and media-handling problems.
	Make sure the MFP is not exposed to direct sunlight or to heating or cooling vents. Allow time for
	the MFP and media to acclimate whenever changing environments (for example, moving from a
	cold environment to a warm one). Acclimation can take anywhere from 3 to 24 hours depending
	on the ambient conditions.
