Table 13. Solving image-quality problems Problem Cause Solution Blank pages print occasionally. Page length and margins are not set correctly for the paper size. If you are printing on small-sized paper and the page is blank, try printing on larger paper to see where the image is printing. Adjust the margins accordingly. Your HP LaserJet 3200 product is feeding two or more sheets of paper at a time because the paper is difficult to separate. Remove the paper from the paper input bin and align the edges of the paper. “Break” the ream of paper by curving it into an upside-down u-shape. Try turning the paper around to feed the other end first, or use a different type of paper.
Clean the pickup roller and the separation pad. If the problem persists, replace the separation pad or subpads. Your software application is sending an extra page-eject command. Check your software’s printing configuration information. If you are using a word-processing program, check for a natural page break and a forced page break that are close to each other. Blank pages are always printing. The toner cartridge was improperly installed. Make sure you removed the entire length of the sealing tape from the toner cartridge before you installed it. The toner cartridge is completely out of toner. Replace the toner cartridge. Discontinuity exists in the high-voltage contact points.
Perform the high-voltage power supply check (see page 171). There is a problem in a part of the product. Print a self-test page. If the page is blank, follow the steps in “Basic troubleshooting” on page 146 to isolate the problem. Replace the laser/scanner or the ECU as needed. Print is misaligned on the page (skewed pages). The paper input tray is overfilled. Remove some of the media. The guides are adjusted improperly. Be sure to center the media with the paper guides. Also, verify that the paper guides are not adjusted too tightly or too loosely against the media. The paper’s weight or surface finish does not meet HP’s specifications. Make sure that the media meets HP’s specifications.
