Slide the guides against the sides of the stack in the paper input bin or against the single sheet in the single-sheet input slot to center the paper. Make sure the guides are not adjusted too tightly.

Always remove paper from the paper input bin before refilling the bin.

Remove some of the sheets. The paper input bin can hold up to 100 sheets of 20- lb (75g/m2) bond weight paper (less for heavier paper) or up to 7 to 10 envelopes.

More than one sheet was placed in the single-sheet input slot.

The paper was poorly cut by the manufacturer and is sticking together.

Place only one sheet at a time in the single-sheet input slot.

“Break” the ream of paper by curving it into an upside-down u-shape; this may effectively decrease multifeeds. Also try turning the paper around to feed the opposite end first, or use a different type of paper.

The paper does not meet HP’s specifications for print media.

The output capacity was exceeded in the paper output bin or front paper output slot.

The pickup roller is dirty.

Make sure that the media meets specifications detailed in HP’s media specifications guide.

Do not allow more than 100 sheets of 20- lb (75g/m2) bond weight paper (less for heavier paper) to fill the paper output bin. Do not allow more media to stack up in front of the front paper output slot.

See the appropriate sections of Chapter 3, “Maintenance.”

Replace the separation pad.

Check the sensors to make sure that none of them are jammed. If a sensor cannot be “unjammed,” replace the sensor.
