If roll paper does not feed, cut the end straight across and uncurl it by rolling it backward, if necessary. Then reload the paper. If thick media does not feed, make sure you are loading it straight into the product, not at an angle. If paper jams when you print on both sides of the paper, try loading fewer sheets.
Make sure the paper is not curled or folded. If so, flatten it or curl it slightly toward the opposite side before loading. Remove the stack of paper and make sure that the paper is not too thin. Fan the edges of the stack to separate the sheets, then reload the paper.
The photo tray is overloaded. The paper is curled. The print side, or shiny side, of the paper is not loaded in the tray face down. The paper width guide is too tight against the paper stack.
Dust, paper fiber, and other debris might accumulate on the pick rollers and cause paper feed issues. To help prevent paper feed issues, clean the rollers inside the printer and in the duplexer (if equipped).
For cleaning, HP recommends using HP Equipment Cleaning Wipes, but you can use an HP-approved lint-free wipe and deionized or distilled water. Note: If dark spots appear on back side of prints, clean drum screen. Note: If minilab prints more than 2000 prints each day, clean drum screen up to twice daily.
Automatic print head cleaning
The cleaning function is included in the software of almost every printer. Usually, you can find it under the “printer maintenance” section of your printer`s display menu. Automatic print head cleaning usually takes only one or two minutes, so you won`t need to wait for too long.

As a rule of thumb, to achieve photo quality print, you will need to use an image resolution of 300 pixels per inch. We write this as 300 DPI and means that in each inch of your print there will be 300 pixels.
Dust, paper fiber, and other debris might accumulate on the paper feed rollers and cause paper jams and paper feed issues. Clean the rollers inside the printer, and then try to print again.
In general, printer rollers are rubber-based wheel-type components that are designed to grab paper from the paper trays for feeding into printers.
