Table 14. Solving paper feed problems Problem Cause Solution The product feeds multiple sheets or jams frequently from the paper input bin or single-sheet input slot. Paper guides are not adjusted properly. Slide the guides against the sides of the stack in the paper input tray or against the single sheet in the single-sheet input tray to center the paper. Make sure the guides are not adjusted too tightly. The special media lever is in the wrong position. Slide the special media lever back to the normal position. Only slide the special media lever to the right when copying or scanning special media. Paper was not removed from the paper input tray before refilling the tray.
Always remove paper from the paper input tray before refilling it. The paper input tray is overfilled. Remove some of the sheets. The paper input tray can hold up to 125 sheets of 20-lb. (75g/m 2 ) bond weight paper (less for heavier paper) or from 7 to 10 envelopes. More than one sheet was placed in the single-sheet input slot. Place only one sheet at a time in the single-sheet input slot. The paper was poorly cut by the manufacturer and is sticking together. “Break” the ream of paper by curving it into an upside-down u-shape; this can 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. Make sure that the media meets specifications detailed in HP’s media specifications guide. The output capacity was exceeded in the paper output bin or front paper output slot. Do not allow more than 100 sheets of 20- lb (75g/m 2 ) bond weight paper (less for heavier paper) to fill the paper output bin. The pickup roller is dirty. See chapter 3, “Maintenance.” The pickup roller is damaged. Replace the pickup roller. The separation pad is dirty. Clean the separation pad. The separation pad is damaged. Replace the separation pad. A sensor is not operating properly. Check the sensors to make sure that none of them are jammed.
If a sensor cannot be “unjammed,” replace the sensor. There is a problem in the paper path. Perform the “paper path check” (see page 173) to determine which parts should be replaced. EN Solving paper feed problems 165
