Troubleshooting Print Quality Issues

  • PrintPrint

Introduction

This document offers solutions to resolve print-quality problems for HP All-In-One products.

Colors on printout are wrong or fade in and out while printing

The most common problem is that the colors fade or are not correct. This usually occurs when the print cartridge is low on one or more colors of ink.
Figure 1: Example printout where the yellow ink is running low
To verify that the ink is running low, check the estimated ink levels by following these steps:
  1. Click Start , click Programs (click All Programs in Windows XP), click Hewlett-Packard , select the all-in-one product folder, and then click HP Toolbox .
  2. In the Printer Toolbox, select the Estimated Ink Level tab. Replace any ink cartridge that has one or more of the colors of ink low or empty.
    NOTE: The HP Officejet D and 7100 series should never be allowed to completely run out of ink. Running completely out of ink could cause severe damage to the printheads and ink delivery system.
If the estimated ink levels look OK, follow these additional steps:
  1. Print a self-test page by following these steps:
    From the front panel of the all-in-one, press Menu (or Setup).
    Press the Right Arrow key until the display reads Print Reports , and then press Enter .
    Press the Right Arrow key until the display reads Self-Test Report , and then press Enter .
    Figure 2: A self-test report (the HP Officejet D and 7100 series will look different)
  2. Examine the colors on the test page.
    • If the colors on the test page are not correct, review an HP document with information on the topic (buu02176) (in English) to learn how to clean the print cartridge and print carriage. If the problem cannot be corrected, replace the print cartridge.
    • If the colors on the test page are correct, continue troubleshooting with the remaining steps.
  3. Open the print properties before printing. Click File , click Print , and then click Properties from with the application you are printing from to open the Print Properties.
    • Check the Advanced tab and verify that no color adjustments have been done in the print driver. Click Factory Settings and OK to return the settings to the factory defaults.
    • Verify that the proper paper type is being used and that this paper type has been selected in the Paper type setting on the Setup tab of the Print driver settings. If there is an off color tint when printing on some photo papers, try selecting Plain Paper as the paper type.
  4. Assign a color management profile to the all-in-one. To do this, follow the steps below:
    1. Click Start , click Settings , and then click Printers (in Windows XP, click Start , then click Printers and Faxes ) to open the Printers folder.
    2. In the Printers folder, right-click the HP all-in-one printer icon and then click Properties .
    3. Click the Color Management tab.
    4. Click Add to see the list of available color profiles.
    5. In the Add Profile Association box, select Diamond Compatible 9300k G2.2.icm .
    6. Click Add and then click OK . Print the file again. If the application you are printing from does not print in color, use Microsoft Paint to print a document containing colors.
    7. Try printing again and see if the colors are better.
  5. If the colors are just slightly incorrect, try using color adjustment settings on the Advanced tab of the Print Properties.
  6. If you are using refilled or remanufactured print cartridges, try replacing them with a new genuine HP print cartridge. Differences in the inks, contamination of the ink, or damage to the print cartridge may cause poor print quality. HP will not support any print quality problems caused by refilled or remanufactured print cartridges.

Faded or grainy lines in printout

Perform the following steps to reduce or eliminate faded or grainy lines:
  1. Print at a higher quality setting.
  2. Verify that the paper you are printing on will lay flat. Paper that is not laying flat can cause banding when the paper transitions over the rollers or cause the print cartridges to scrape across the surface of the page. Check the top sheet of paper by removing it from the all-in-one and placing it on a flat surface. If the paper does not lie flat, bend it in the opposite direction to straighten it.

    2 - Faded or grainy bands due to print cartridge scrape on paper that is not flat

Print has white streaks

This problem will occur if the print settings are incorrect or if the ink cartridge is low on ink or has clogged nozzles. To correct it, perform the following steps:
  1. Try printing with a higher Print Quality setting.
  2. Try cleaning the print cartridge from the Maintenance utility by following the steps below:
    1. On the all-in-one front panel, press Setup (or Menu) repeatedly until "Maintenance " displays, then press Enter .
    2. When "Clean Cartridges " displays, press Enter .
    3. At the end of the cartridge cleaning cycle, a page will print. Examine the page to determine if the problem is corrected.
  3. If the problem still exists, clean the cartridge following the directions below in the "Clean under the cartridges and the carriage " section below.
  4. Verify that the ink cartridge is not low on ink by checking the estimated ink levels as indicated in the "Colors on printout are wrong or fade in and out while printing " section above.
  5. Replace the print cartridge for the color that is not printing correctly.

Printout appears fuzzy or jagged

  1. Verify there is not another object near the HP all-in-one product that is producing vibrations that are being transmitted into the unit by the surface that the unit is resting on.
  2. Run a print alignment from the help section of the all-in-one software or from the print driver properties.
  3. This problem can also occur when using low quality paper. The paper does not absorb the ink correctly resulting in this problem. Heavier weight papers will be less likely to have this problem.

Ink bleeds or smears

Use the proper paper setting

Ink drying time varies depending on the type of paper being used. Transparencies and higher-quality paper such as photo papers take longer to dry after printing. Match the paper type being used in the Setup tab of the Print Settings or the Copy Paper Type under Copy Setup in the menu.

Increase the ink drying time

  1. From the application being printed from, click File and Print .
  2. When the Print dialog box appears, select Properties or Setup .
  3. In the Print Settings window, select the Advanced tab.
  4. Adjust the Extra Drying Time slider in the lower-right corner toward More .
  5. Try the print job again and adjust if necessary.

Reduce the amount of ink used

  1. From the application being printed from, click File and Print .
  2. When the Print dialog box appears, select the Properties or Setup button.
  3. In the Print Settings window, select Advanced .
  4. Adjust the Ink Volume setting to the left one level.
  5. Try printing the document in Fast mode.

Is the paper too thick or damaged

Card stock in excess of 60 pound weight or curled paper may cause the bottom of the ink cartridge to come in contact with the paper. If this happens, the print will smear and the cartridge may become damaged.

Clean under the cartridges and the carriage

  1. Turn the HP all-in-one product on and lift the top cover.
  2. After the print cartridges have moved to the left of center, unplug the power cord from the back of the printer.
  3. Remove the print cartridges from the carriage and place them on their sides on a scrap piece of paper.
    CAUTION: Once the print cartridges have been removed, make sure they are not outside of the printer more than 30 minutes.
    WARNING: Keep print cartridges out of the reach of children.
  4. Dip a clean cotton swab into distilled water and squeeze any excess water from the swab.
  5. Grasp one of the print cartridges by the sides or top. Clean around the outside of the nozzle plate. Do not wipe or touch the nozzle plate (the shiny rectangle on the very bottom of the cartridge).
    Figure 5: Nozzle plate
    1 - Do NOT clean Nozzle Plate
    2 - Clean
  6. Clean the other print cartridge in the same manner.
  7. Hold the print cartridges up to the light to inspect for fibers on the face and edges. If fibers are still present, clean the cartridge again.
  8. Dampen a lint-free cotton cloth with distilled water, fold it over a few times and slide it under the bottom of the carriage. Slide the cloth to the left and right when inserting it under the carriage to ease insertion. Continue sliding the cloth to the left and right to remove excess ink and fibers from the underside of the carriage.
  9. Replace the print cartridges, plug the power back into the HP all-in-one product and align the cartridges.

Paper is curling because too much ink is being applied

Some papers cannot absorb enough ink to work correctly at all print settings. Verify that the correct paper type is selected in the print properties and then do one or both of the following to correct the problem.
  1. In the print properties, reduce the Print Quality setting one level.
  2. To reduce the amount of ink being applied to the page, do the following:
    1. From the application being printed from, click File and Print .
    2. When the Print dialog box appears, select the Properties or Setup button.
    3. In the Print Settings window, select Advanced .
    4. Adjust the Ink Volume setting to the left one level.
  3. Replace the ink cartridge with a new one.

Edges of print are cut off or a white border around the printout

Inkjet printing requires greater print margins to keep ink from being sprayed into the printer. Printer damage will occur if ink is inadvertently sprayed into the print mechanism and usually gets deposited on printouts as smears or blotches. The HP all-in-one product automatically adjusts the printable region so this will not occur. The print margin values are given in the table below. Adjust the margin, header or footer settings from within the application to accommodate these requirements. In most applications (such as Word), these settings can be adjusted from the Page Setup feature under File menu.

Meaningless characters print during computer power cycle

There are two possible reasons for this problem.

Other drivers putting signals onto the parallel port

Another device driver, such as a printer, external drive, or application that uses a software key, is sending information out onto the parallel port. Some devices leave files on the computer even if the software is uninstalled. Check with the manufacturer of any other devices or programs that access the parallel port of the computer for information on how to completely remove the drivers or how to disable the components that access the parallel port.

Grounding issues

The PC's hardware is generating signal noise and sending it down the bidirectional lines of the communication cable. The HP all-in-one product receives the electrical signal and tries to interpret it as a print job. Plug the HP all-in-one product power supply directly into a wall outlet. If the problem continues, verify the outlet is grounded properly (some older buildings do not have properly grounded outlets).

Print does not cancel right away after the Cancel button is pressed

After Cancel is pressed, there may be a slight delay before the print job is canceled. During this period of time an error may occur if a new print job is attempted. The length of time before the print job cancels is directly related to the size and complexity of the print job. The larger and more complex the print job, the longer it takes to cancel, sometimes several minutes may pass.
The delay is a result of clearing the print job out of the print queue. For large and complex print jobs such as large spreadsheets or presentations application slides, it will be much quicker to manually cancel the print job than to wait for it to clear. To manually clear the print job after Cancel has been pressed:
  1. Click Start , Settings , and Printers to open the Printers folder.
  2. Double-click the HP all-in-one product icon. A window will open showing the print jobs queued for the unit.
  3. The print job that was canceled will still show as "Printing " in the status section. Highlight this print job by clicking it.
  4. Click the Document menu option and select Cancel Printing .
  5. Close the window.

Print is not straight

There are a couple of conditions that can cause the print to be skewed on the page. Review the information below.
  1. The rear access door or two-sided printing accessory not being in the locked position is the most common reason for skewed or crooked printing and copying.
    1. Remove and then replace and lock the rear-access door or two-sided printing accessory.
      Figure 6: Locating the rear-access door
    2. Examine the rollers on the rear access door or two-sided printing accessory. They should turn freely. Clean the rollers if they do not turn freely.
    3. Reinstall the rear access door or two-sided printing accessory. Verify that it is fully locked in place.
    4. Print another self-test page to determine if the problem is corrected.
  2. If the rear access door is in the locked position but the problem remains, clean the paper pickup wheels.
    1. Remove the paper from the paper tray.
    2. Remove the rear access door or two sided printing accessory.
    3. Disconnect the power cable from the back of the all-in-one.
    4. Locate the three paper feed rollers as indicated below.
      Figure 7: The paper feed pickup rollers
    5. Take a lint free cloth and make it damp with a little water. Too much water may damage the electrical circuit in the unit.
    6. Clean the rollers with the cloth. With the power cable disconnected, the roller can be turned by hand.
    7. Allow the rollers to dry for a few minutes and then reinstall the rear access door. Make sure that it is completely locked in place.
    8. Put the paper back in the input tray and reconnect the power cable.
    9. Print another self-test page to determine if the problem still exists.
  3. Proper loading and handling of the paper can minimize skew. Make sure the paper is loaded evenly against the right wall of the main paper tray.
  4. Make sure the paper width and length adjusters fit snugly against the left and bottom edges of the paper stack so the paper is being fed "squarely" into the printer.
  5. Use envelopes with rectangular flaps rather than triangular flaps.
  6. Load only one type of paper or transparency in the input tray. Some types of paper and preprinted forms or letterhead can impact print skew.
  7. Remove the rear access door and clean the rollers with a damp cloth. Turn the knob on the rear access door a quarter-turn counter clockwise to the unlocked position to release the door. Remove the rear access door and clean the rollers with a damp cloth. It is possible to manually turn the rollers either direction with fingers.
  8. If the HP two-sided printing accessory is attached (optional on some products), verify the clean-out door of the accessory is fully closed and latched.

Problems printing from the secondary operating system of a dual boot computer

The HP all-in-one product cannot be installed on both operating systems of a dual boot computer. For all-in-one products using a parallel cable, install an alternative printer driver on the secondary operating system. The following drivers will work:
  • The HP Deskjet 970 series (may be available through the Add Printers Wizard)
  • The HP Deskjet 895 series (may be available through the Add Printers Wizard)
  • The HP Deskjet 550C series (available through the Add Printers Wizard)
For USB only all-in-one products, there is no solution and there is no compatible print driver.
