A “Cartridge is low” or “Cartridge is very low” message displays on the product control panel

Cartridge is low: The product indicates when a toner cartridge level is low. Actual toner cartridge life remaining may vary. Consider having a replacement available to install when print quality is no longer acceptable. The toner cartridge does not need to be replaced now.

Cartridge is very low: The product indicates when the toner cartridge level is very low. Actual toner cartridge life remaining may vary. Consider having a replacement available to install when print quality is no longer acceptable. The toner cartridge does not need to be replaced now unless the print quality is no longer acceptable.

Once an HP toner cartridge has reached Very Low, HP's Premium Protection Warranty on that toner cartridge has ended.

Change the "Very Low" settings

You can change the way the product reacts when supplies reach the Very Low state. You do not have to re-establish these settings when you install a new toner cartridge.

  1. From the Home screen on the product control panel, scroll to and touch Supplies.
  2. Open the following menus:

  3. Manage Supplies
    • Supply Settings

  4. Black Cartridge or Color Cartridges
    • Very Low Settings

  5. Select one of the following options:

  6. Select the Stop option to set the product to stop printing when the cartridge reaches the Very Low threshold.

  7. Select the Prompt to continue option to set the product to stop printing when the cartridge reaches the Very Low threshold. You can acknowledge the prompt or replace the cartridge to resume printing.
  8. Select the Continue option to set the product to alert you that the cartridge is very low, and to continue printing beyond the Very Low setting without interaction. This can result in unsatisfactory print quality.

For products with fax capability

When the product is set to the Stop or Prompt to continue option, there is some risk that faxes will not print when the product resumes printing. This can occur if the product has received more faxes than the memory can hold while the product is waiting.

The product can print faxes without interruption when it passes the Very Low threshold if you select the Continue option for the toner cartridge, but print quality might degrade.

Improve print quality

If the product is having print-quality problems, try the following solutions in the order presented to resolve the issue.

• Print from a different software program
- Check the paper-type setting for the print job
- Check toner-cartridge status
• Calibrate the product to align the colors
• Print a cleaning page
• Visually inspect the imaging-drum
- Check paper and the printing environment
• Check other print job settings
• Try a different print driver
• Set the individual tray alignment

Try printing from a different software program. If the page prints correctly, the problem is with the software program from which you were printing.

Check the paper-type setting for the print job

Check the paper type setting when printing from a software program and the printed pages have smears, fuzzy or dark print, curled paper, scattered dots of toner, loose toner, or small areas of missing toner.

Check the paper type setting (Windows)

  1. From the software program, select the Print option.
  2. Select the product, and then click the Properties or Preferences button.
  3. Click the Paper/Quality tab.
  4. From the Paper Type drop-down list, click the More... option.
  5. Expand the list of Type is: options.
  6. Expand the category of paper types that best describes your paper.
  7. Select the option for the type of paper you are using, and click the OK button.
  8. Click the OK button to close the Document Properties dialog box. In the Print dialog box, click the OK button to print the job.

Check the paper type setting (Mac OS X)

  1. Click the File menu, and then click the Print option.
  2. In the Printer menu, select the product.

  3. By default, the print driver displays the Copies & Pages menu. Open the menus drop-down list, and then click the Finishing menu.

  4. Select a type from the Media Type drop-down list.
  5. Click the Print button.

Check toner-cartridge status

Follow these steps to check the estimated life remaining in the toner cartridges and if applicable, the status of other replaceable maintenance parts.

Step one: Print the supplies status page

  1. From the Home screen on the product control panel, scroll to and touch the Supplies button.
  2. The status of all supply items is listed on the screen.
  3. To print or view a report of the status of all supply items, including the genuine HP part number for reordering the supply, touch the Manage Supplies button. Touch the Supplies Status button, and then touch either the Print or View button.

Step two: Check supplies status

  1. Look at the supplies status report to check the percent of life remaining for the toner cartridges and if applicable, the status of other replaceable maintenance parts.

Print quality problems can occur when using a toner cartridge that is at its estimated end of life. The supplies status page indicates when a supply level is very low. After an HP supply has reached the very low threshold, HP's premium protection warranty on that supply has ended.

The toner cartridge does not need to be replaced now unless the print quality is no longer acceptable. Consider having a replacement available to install when print quality is no longer acceptable.

If you determine that you need to replace a toner cartridge or other replaceable maintenance parts, the supplies status page lists the genuine HP part numbers.

  1. Check to see if you are using a genuine HP cartridge.

A genuine HP toner cartridge has the words “HP” or “Hewlett-Packard” on it, or has the HP logo on it. For more information on identifying HP cartridges go to www.hp.com/go/learnaboutsupplies.

Calibrate the product to align the colors

Calibration is a product function that optimizes print quality.

Follow these steps to resolve print print-quality problems such as misaligned color, colored shadows, blurry graphics, or other print-quality issues.

  1. From the Home screen on the product control panel, scroll to and touch the Device Maintenance button.
  2. Open the following menus:

  3. Calibration/Cleaning
    Full Calibration

  4. Touch the Start button to start the calibration process.

A Calibrating message will display on the product control panel. The calibration process takes a few minutes to complete. Do not turn the product off until the calibration process has finished.

  1. Wait while the product calibrates, and then try printing again.

During the printing process paper, toner, and dust particles can accumulate inside the product and can cause print-quality issues such as toner specks or spatter, smears, streaks, lines, or repeating marks.

Follow these steps to clean the product's paper path.

  1. From the Home screen on the product control panel, scroll to and touch the Device Maintenance button.
  2. Touch Calibration/Cleaning, touch Cleaning Page, and then touch Print to print the page.

A Cleaning message displays on the product control panel. The cleaning process takes a few minutes to complete. Do not turn the product off until the cleaning process has finished. When it is finished, discard the printed page.

Visually inspect the imaging-drum

Follow these steps to inspect each imaging drum.

  1. Remove the imaging drum from the product.
  2. Check the memory chip for damage.
  3. Examine the surface of the green imaging drum.

HP Color LaserJet Enterprise M855xh - Visually inspect the imaging-drum - 1

CAUTION: Do not touch the imaging drum. Fingerprints on the imaging drum can cause print-quality problems.

  1. If you see any scratches, fingerprints, or other damage on the imaging drum, replace it.
  2. Reinstall the imaging drum, and print a few pages to see if the problem has resolved.

Check paper and the printing environment

Step one: Use paper that meets HP specifications

Some print-quality problems arise from using paper that does not meet HP specifications.

• Always use a paper type and weight that this product supports.
- Use paper that is of good quality and free of cuts, nicks, tears, spots, loose particles, dust, wrinkles, voids, staples, and curled or bent edges.
• Use paper that has not been previously printed on.
• Use paper that does not contain metallic material, such as glitter.
- Use paper that is designed for use in laser printers. Do not use paper that is designed only for use in Inkjet printers.
• Use paper that is not too rough. Using smoother paper generally results in better print quality.

Step two: Check the environment

The environment can directly affect print quality and is a common cause for print-quality or paper-feeding issues. Try the following solutions:

  • Move the product away from drafty locations, such as open windows or doors, or air-conditioning vents.
    • Make sure the product is not exposed to temperatures or humidity outside of product specifications.
  • Do not place the product in a confined space, such as a cabinet.
  • Place the product on a sturdy, level surface.
  • Remove anything that is blocking the vents on the product. The product requires good air flow on all sides, including the top.
  • Protect the product from airborne debris, dust, steam, grease, or other elements that can leave residue inside the product.

Check other print job settings

When printing from a software program, follow these steps to try to resolve the issue by adjusting other print-driver settings.

Adjust color settings (Windows)

Follow these steps if colors on the printed page to not match colors on the computer screen, or if the colors on the printed page are not satisfactory.

Change the color theme

  1. From the software program, select the Print option.
  2. Select the product, and then click the Properties or Preferences button.
  3. Click the Color tab.
  4. Select the HP EasyColor check box to clear it.
  5. Select a color theme from the Color Themes drop-down list.

  6. Default (sRGB): This theme sets the product to print RGB data in raw device mode. When using this theme, manage color in the software program or in the operating system for correct rendering.

  7. Vivid (sRGB): The product increases the color saturation in the midtones. Use this theme when printing business graphics.
  8. Photo (sRGB): The product interprets RGB color as if it were printed as a photograph using a digital mini lab. The product renders deeper, more saturated colors differently than with the Default (sRBG) theme. Use this theme when printing photos.
  9. Photo (Adobe RGB 1998): Use this theme with printing digital photos that use the AdobeRGB color space rather than sRGB. Turn off color management in the software program when using this theme.

• None: No color theme is used.
- Custom Profile: Select this option to use a custom input profile to accurately control color output (for example, to emulate a specific HP Color LaserJet product). Download custom profiles from www.hp.com.

  1. Click the OK button to close the Document Properties dialog box. In the Print dialog box, click the OK button to print the job.

Change the color options

  1. From the software program, select the Print option.
  2. Select the product, and then click the Properties or Preferences button.
  3. Click the Color tab.
  4. Select the HP EasyColor check box to clear it.
  5. Click the Automatic or Manual setting.

• Automatic setting: Select this setting for most color print jobs
- Manual setting: Select this setting to adjust the color settings independently from other settings. Click the Settings button to open the manual color-adjustment window.
