HP LaserJet Pro MFP M128fw

The following problems with paper cause print-quality deviations, jamming, or damage to the product.

Problem	Cause	Solution
Poor print quality or toner adhesion	The paper is too moist, too rough, too heavy or too smooth, is embossed, or from a faulty paper lot.	Try another kind of paper, between 100 and 250 Sheffield, with 4% to 6% moisture content.
Dropouts, jamming, or curl	The paper has been stored incorrectly.	Store paper flat in its moisture-proof wrapping.
	The paper has variability from one side to the other.	Turn the paper over.
Excessive curl	The paper is too moist, has the wrong grain direction, or is of short-grain construction.	Use long-grain paper.
	The paper varies from side-to-side.	Turn the paper over.
Jamming, damage to product	The paper has cutouts or perforations.	Use paper that is free of cutouts or perforations.
Problems with feeding	The paper has ragged edges.	Use high-quality paper that is made for laser printers.
	The paper varies from side-to-side.	Turn the paper over.
	The paper is too moist, too rough, too heavy or too smooth, has the wrong grain direction, is of short-grain construction, or it is embossed, or from a faulty paper lot.	Try another kind of paper, between 100 and 250 Sheffield, 4% to 6% moisture content. Use long-grain paper.
Print is skewed (crooked).	The paper guides might be incorrectly adjusted.	Remove all paper from the input tray, straighten the stack, and then load the paper in the input tray again. Adjust the paper guides to the width and length of the paper that you are using and try printing again.
More than one sheet feeds at one time.	The paper tray might be overloaded.	Remove some of the paper from the tray.
	The paper might be wrinkled, folded, or damaged.	Verify that the paper is not wrinkled, folded, or damaged. Try printing on paper from a new or different package.
The product does not pull paper from the input tray.	The product might be in manual-feed mode.	At the computer, follow the on-screen instructions to deactivate manual-feed mode. Or, at the product, open and close the toner-cartridge door.
	The pickup roller might be dirty or damaged.	Replace the roller.
	The paper-length adjustment control in the input tray is set at a length that is greater than the paper size.	Set the paper-length adjustment control to the correct length.
