EN 6 Troubleshooting183 Solving image-quality problems If your document is printing but the quality is not what you expected, start by using the print- quality checklist. Print-quality checklist General print-quality problems can be solved by following the checklist below. 1Check the printer driver to make sure that you are using the best available print-quality option, or return to the default settings. See the user guide for more information about print- quality options. 2 Make sure that the paper or print media you are using meets specifications. See the user guide for more information. Generally, smoother paper provides better results (although coated, photo, and glossy papers are not supported). 3 If you are using a special print media such as labels, transparencies, or letterhead, make sure that you selected the correct media type (see the Paper tab in the printer driver). See the user guide for information about HP print-media specifications. 4 Print a Configuration page and Supplies Status page at the printer by pressing ( G O) and ( C ANCELJOB) simultaneously. If the pages do not print, then the problem is in the hardware rather than in the software. Check printer status messages on the Configuration page. Check the Supplies Status page to see if any supplies are low or empty. Note that no information is provided for non-HP print cartridges. Replace non-HP print cartridges with HP print cartridges. 5 Print a Demo page from the HP Color LaserJet 2500 Series Toolbox. If the page prints, the problem might be in the printer driver. Try printing from one of the other printer drivers. For example, if you are using the PCL 6 printer driver, print from the PCL 5c or PS printer driver. 6 Try printing from a different program. If the page prints correctly, the problem might be in the program from which you were printing. 7 Restart the computer and the printer and try printing again. If the problem is not resolved, choose one of these options: If the problem is affecting all printed pages, see “Solving image-quality problems (all print jobs) ” on page 184. If the problem is affecting only pages that are printed in color, see “Solving image-quality problems (color print jobs) ” on page 191.
184Troubleshooting C9706-90926 Solving image-quality problems (all print jobs) The examples below depict letter-size paper that has passed through the printer short-edge first. These examples illustrate problems that would affect all pages you print, whether you print in color or in black only. The topics that follow list the typical cause and solution for each of these examples. Light print or fade Toner specksDropouts Vertical lines Gray background Toner smearLoose toner Repetitive defects on the front Repetitive defects on the back Misformed characters Curl or wave Page skew Wrinkles or creases Toner scatter outlineRandom image repetition (light)Random image repetition (dark)
EN 6 Troubleshooting185 Light print or fade A vertical streak or an incorrect or faded color area appears on the page. The paper might not meet HP ’s paper specifications (for example, the paper is too moist or too rough). See the user guide for information about print-media specifications. One or more print cartridges are low. If you are using non-HP print cartridges, no messages appear on the printer control panel or in the embedded Web server. The imaging drum might be low or empty. Print the Supplies Status page to check remaining life. Replace the imaging drum if it is low or empty. If none of the print cartridges or the imaging drum is low or empty, remove the print cartridges one at a time and inspect the toner roller in each to see if the roller is damaged. If so, replace the print cartridge. Inspect the imaging drum for toner dust, oil, or fingerprints. If the problem is not resolved, see “If the problem is not resolved ” on page 190. Toner specks The paper might not meet specifications. For example, the paper is too moist or too rough. See the user guide for information about print-media specifications. The paper path might need to be cleaned. Open the HP Color LaserJet 2500 Series Toolbox to use the cleaning page. See “To use a cleaning page ” on page 53 for details. If using a cleaning page did not solve the problem, then check the fuser for contamination and replace the fuser, if necessary. If the problem is not resolved, see “If the problem is not resolved ” on page 190. Dropouts Faded areas, generally rounded, occur randomly on the page. A single sheet of paper might be defective. Try reprinting the job. The paper path might need to be cleaned. Open the HP Color LaserJet 2500 Series Toolbox to use the cleaning page. See “To use a cleaning page ” on page 53 for details. The moisture content of the paper is uneven or the paper has moist spots on its surface. Try different paper, such as high-quality paper intended for laser printers. See the user guide for information about print-media specifications. The paper lot is flawed. The manufacturing processes can cause some areas to reject toner. Try a different brand of paper, such as high-quality paper intended for laser printers. See the user guide for information about print-media specifications. The imaging drum might be defective. See “ Repetitive defects on the front” on page 187. If the problem is not resolved, see “If the problem is not resolved ” on page 190.
186Troubleshooting C9706-90926 Vertical lines Vertical streaks or bands appear on the page. One or more print cartridges are low or defective. Print the Supplies Status page to check remaining life. If you are using non-HP print cartridges, no messages appear on the printer control panel or in the embedded Web server. Clean the printer using a cleaning page. Open the HP Color LaserJet 2500 Series Toolbox to use the cleaning page. See “To use a cleaning page ” on page 53 for details.

If the problem is not resolved, see “If the problem is not resolved ” on page 190. Gray background The amount of background toner shading is unacceptable. Clean the density sensor and perform a calibration. See “Cleaning the engine ” on page 53. Use a different paper with a lighter basis weight. See the user guide for information about print-media specifications. Check the printer environment. Very dry (low humidity) conditions can increase the amount of background shading. One or more print cartridges are low. If you are using non-HP print cartridges, no messages appear on the printer control panel or in the embedded Web server. The imaging drum might be low or empty. Print the Supplies Status page to check remaining life. Replace the imaging drum if it is low or empty. If the problem is not resolved, see “If the problem is not resolved ” on page 190. Toner smear Toner smears appear on the leading edge of the paper. Check the paper type and quality. Use a different paper, such as high-quality paper intended for laser printers. See the user guide for information about print-media specifications. If toner smears appear on the leading edge of the paper, the paper guides are dirty, or debris is in the print path. Open the HP Color LaserJet 2500 Series Toolbox to use the cleaning page. See “To use a cleaning page ” on page 53 for details. The imaging drum might be low or empty. Check the status of the imaging drum at the printer control panel or in the embedded Web server and replace the imaging drum if it is low or empty. The fuser might not be heating correctly. If the printer is plugged into a surge protector, plug it directly into the wall. If the problem is not resolved, see “If the problem is not resolved ” on page 190.
