Table 20. Solving print paper-feed problems (continued) Problem Cause Solution The printer feeds multiple sheets or jams frequently from the main input tray or priority input tray. Paper guides are not adjusted properly. Slide the guides against the sides of the stack in the main input tray or the priority input tray to center the paper. Make sure the guides are not adjusted too tightly. Paper was not removed from the main input tray before refilling the tray. Always remove paper from the main input tray before refilling it. The main input tray is overfilled. Remove some of the sheets. The main input tray can hold up to 250 sheets of 20-lb.
(75 g/m 2 ) bond weight paper (less for heavier paper) or from 20 to 30 envelopes. The priority input tray is overfilled. Remove some of the sheets. The priority input tray can hold up to ten sheets of 20-lb. (75 g/m 2 ) bond weight paper (one sheet of heavier paper) or one envelope. 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 the Print Media Guide for the HP LaserJet family. The output capacity was exceeded in the paper output bin. Do not allow more than 125 sheets of 20-lb. (75 g/m 2 ) bond weight paper (less for heavier paper) to fill the paper output bin. The pickup roller is dirty. Clean the pickup roller. See “Cleaning the printer pickup roller” on page 61. The pickup roller is damaged. Replace the pickup roller. (See “Replacing the printer pickup roller” on page 63.) The separation pad is dirty. Clean the separation pad. (See “Cleaning the printer separation pad” on page 62.) The separation pad is damaged. Replace the separation pad.
(See “Replacing the printer separation pad” on page 65.) 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. 198 Chapter 6 - Troubleshooting EN
