HP Color LaserJet Pro M252, M274, M277 Printers - Fixing Poor Print Quality

This document is for the HP Color LaserJet Pro M252n, M252dw, MFP M274n, and MFP M277n and M277dw Printers.

The quality of a printed document is not as expected. The procedures in this document should help with print quality problems such as smeared, fuzzy, dark, or faded print, and loose, partially missing, or scattered toner.

Solution one: Use genuine HP toner cartridges

HP recommends that you use genuine HP ink or toner supplies. HP cannot guarantee the quality or reliability of non-HP or refilled cartridges. If you do not use genuine HP cartridges, the steps in this document might not resolve the issue. To check the authenticity of your cartridges, go to the HP anti-counterfeit webpage (in English).

Purchase replacement cartridges and other supplies from the HP Store or local retailers.

Solution two: Check the paper

The quality and type of paper can affect the print job. Follow these guidelines to make sure that the paper is appropriate. If it is not, load an appropriate paper type.

note:

To purchase paper in the United States and Canada, go to the HP Store.

• Use paper that is designed for use in HP LaserJet printers. Do not use paper that is designed only for inkjet printers.

• Do not use paper that is too rough. Smoother paper might result in better print quality.

Try to print the document again with the appropriate paper type.

Solution three: Check the print settings

Sometimes the print settings can affect the print quality. Select your operating system, and then check the print settings to make sure that they are appropriate for your print job.

Windows

Sometimes the print settings can affect the print quality. Follow these steps to check the print settings in Windows 8, modify any settings, and then try the print job again.

1. In the software application you are trying to print from, click File, and then click Print.

   The Print window opens.

2. Open the Properties dialog box.

   Depending on the software application, the button might be Properties, Options, Printer Setup, Printer, or Preferences.

3. Depending on your print job, you might consider modifying the following settings:

   • Paper Type: If you are printing on photo paper, select the type of photo paper you are attempting to print on.

   • Print Quality: If you are dissatisfied with the quality of your printouts, increase the print quality. To print more quickly, decrease the print quality. These options typically include Best, Normal, and Draft modes.

   • Paper Size: If you are printing on a different size of paper than you normally print on, select the correct paper size.

   • Black and White: If you want to print in black and white only, select the grayscale option.

4. After selecting the print settings, click OK to apply the settings, and then click Print.

Mac

Sometimes the print settings can affect the print quality. Follow these steps to check the print settings on a Mac computer, modify any settings, and then try the print job again.

1. Open a document, click File, click Print, and then click Show Details.

2. Click the name of the program, and then select the Paper Type/Quality or Media & Quality menu.

3. Review the following options, and then make any necessary changes:

   • Paper type: If one of the options matches your paper type exactly, select that option.

   • Quality: If you are dissatisfied with the quality of your printouts, increase the print quality. To print more quickly, decrease the print quality.

note:

To save these settings for future print jobs, choose Save in the Presets menu, and then name the new preset. If multiple printers are installed, open System Preferences, and then click Printers & Scanners or Print & Scan (depending on your operating system). Set the Default Printer to Last Printer Used.

Solution four: Check the toner level and replace low or empty toner cartridges

If the print is too light or faded in areas, the toner might be low. Check the toner level to determine if the toner cartridge needs to be replaced.

Step 1: Check the toner level

Select your printer control panel display type, and then follow the steps to check your printer's toner level.

note:

The toner supply level and the percentage of toner cartridge life remaining provide estimates for planning purposes only. When the toner level is low, consider having a replacement toner cartridge available. You do not need to replace toner cartridges until the print quality becomes unacceptable.

Step 2: Check the scanner glass for dirt and smudges

Specks of debris can collect on the scanner glass and white plastic backing, which might affect performance or cause specks or dots on the printed pages.

If the scanner glass and backing need to be cleaned, follow these steps:

1. Gather the following materials:

   • A clean, lint-free cloth or any cloth that does not come apart or leave fibers

   • Distilled, filtered, or bottled water (tap water might damage the printer)

   • A chamois or a cellulose sponge

2. Press the Power button to turn off the printer, and then disconnect the power cord from the electrical outlet.

   warning:

   You must disconnect the power cord to avoid the risk of injuries or electric shock.

3. Open the scanner lid.

4. Moisten the cloth, and then clean the scanner glass and the white plastic backing underneath the scanner lid.

   caution:

   Do not use abrasives, acetone, benzene, ammonia, ethyl alcohol, or carbon tetrachloride on any part of the printer; these can damage the printer. Do not place liquids directly on the glass or platen. They might seep and damage the printer.

5. Dry the glass and white plastic parts with a chamois or a cellulose sponge to prevent spotting.

6. Connect the power cable to an outlet, and then press the Power button to turn on the printer.

7. Try to print again to see if the issue is resolved:

   • If these steps resolved the issue, you do not need to continue troubleshooting.

   • If the issue persists, continue to the next appropriate step or the next solution.

Step 3: Inspect the toner cartridge for damage

Check the toner cartridge for damage if there are issues like toner smears on the printed pages.

1. Remove the toner cartridge from the printer, and then make sure that the sealing tape has been removed.

2. Grasp both ends of the toner cartridge, and then gently rock the cartridge back and forth to distribute the toner.

3. Check the memory chip for damage.

4. Slide back the cartridge cover to expose the imaging drum.

   caution:

   Do not touch the roller (imaging drum) on the toner cartridge. Fingerprints on the imaging drum can cause print quality problems.

   Figure : Slide back the cartridge cover

   

5. Examine the surface of the imaging drum on the toner cartridge.

   • If you see any scratches, fingerprints, or other damage on the imaging drum, replace the toner cartridge.

   • If the imaging drum does not appear to be damaged, close the cover, and then reinstall the cartridge in the printer.

6. Try to print again to see if the issue is resolved:

   • If these steps resolved the issue, you do not need to continue troubleshooting.

   • If the issue persists, continue to the next appropriate step or the next solution.

Step 4: Check the EconoMode settings

If the entire page is too dark or too light, check the EconoMode settings. HP does not recommend the full-time use of EconoMode. If EconoMode is used full time, the toner supply might outlast the mechanical parts in the toner cartridge. If print quality begins to degrade and is no longer acceptable, replace the toner cartridge.

note:

This feature is available with the PCL 6 print driver for Windows. If you are not using that driver, enable the feature with the HP Embedded Web Server.

Follow these steps to check the EconoMode settings:

1. From the software program, select the Print option.

2. Select the printer, and then click Properties or Preferences.

3. Click the Paper/Quality tab, and then locate the Print Quality area.

4. If the entire page is too dark, use these settings:

   • Select the 600 dpi option.

   • Select the EconoMode check box to enable it.

   If the entire page is too light, use these settings:

   • Select the FastRes 1200 option.

   • Clear the EconoMode check box to disable it.

5. Click OK, and then click OK to print the job.

Solution six: Other ways to improve print quality

If there are no defects on the last page you printed, the print mechanism and toner supplies are working correctly. There is no reason to clean or replace the toner cartridges. Instead, try these tips to improve the quality of your print jobs:

• Repeat the first steps in this document to make sure that you are using genuine HP toner cartridges and the appropriate paper type for your print job. Certain paper types might be incompatible with HP printing systems, and HP cannot guarantee the reliability of non-HP toner cartridges.

• Make sure that the printer is operating within the environmental specifications listed in the printer's Warranty and Legal Guide.

• Make sure that the image you are printing has sufficient resolution. Images that have been enlarged too much might appear fuzzy or blurry.

• If the problem is confined to a band near the edge of a printout, use the software that you installed with the printer, or another software program to rotate the image 180°. The problem might not display on the other end of the print job.

• Try to print the same image or text from a different software program.

Solution seven: Service the printer

If the problem persists, the printer might require service. Contact HP to set up service or to find an HP authorized service center.

Service or replace your HP product if the issue persists after completing all the preceding steps.

Go to Contact HP Customer Support to schedule a product repair or replacement. If you are in Asia Pacific, you will be directed to a local service center in your area.

To confirm your warranty status, go to HP Product Warranty Check. Repair fees might apply for out-of-warranty products.

note:

Keep a print sample that shows the problem. If the ink cartridges, printhead, or printer is replaced under warranty, the support agent will request the print sample. If the printer is returned to HP, the print sample must be returned with the printer. Place the sample in the output tray when you package your printer for shipping.
