Your printer might have dust on the hexagonal mirror and other optical components inside the LSU (Laser System Unit). If the printer it's dirty inside, all that dust flows and lay down on components. In course of time, it reaches the optical components and generates a "gradient wiped out" image from left to right as you are looking at the printed page. This problem is common on laser printers. On colour printers, you may find that only one or more colors have this gradient wiped out. Because they have separate Laser System Units.

SOURCE: My Hp 6210 is skipping lines and moving the paper down

note :--do not use refilled cartridges Step 1: Did you just install a new tri-color or photo cartridge? If all three of the following are true, the problem can probably be solved just by letting the printer sit for 30 minutes: You just installed a photo or tri-color print cartridge (the cartridge can be either new or previously-used) The problem appeared right after you installed the cartridge The recently-installed cartridge is the one that is printing the defective patterns on the diagnostic page Sometimes when a tri-color or photo print cartridge is snapped into the print carriage, it ingests a small amount of air, which can prevent some nozzles from working properly. The air soon works its way out of the cartridge. Step 2: Run the clean print cartridges utility If the step above did not solve the problem, clean the print cartridges. Press the Setup button. Use the arrow keys to select Tools and then press the OK button. Select Clean Print Cartridge and then press OK . The device prints a test page. Examine the test page. If the print quality of the page is good, stop here. If the print quality is bad, go on to the next step for further cleaning. Open the Printer Toolbox . There are two ways to do this: Open HP Director , select the Settings menu, then the Print Settings submenu, and finally the Printer Toolbox . If the HP Director method does not work, open Printers and Faxes in the Windows Control Panel , then right-click your printer icon and choose Properties . Click on Printing Preferences . Click the Services tab, then the Service This Device icon. The Printer Toolbox opens. On the Device Services tab, click Clean the Print Cartridges , then follow the on-screen instructions. Up to three levels of cleaning are available. Discard or recycle the page that prints. Step 3: Clean the contacts If the steps have not solved the problem, clean the electrical contacts on the print cartridge and in the carriage in the printer. Gather the following items to clean the cartridge and print carriage: Clean distilled water. Use bottled or filtered water if distilled water is not available. Tap-water can contain contaminants that damage the cartridge. Clean cotton swabs or any soft, lint-free material that will not stick to the cartridges (coffee filters work well) Sheets of paper or a paper towel to rest the cartridges on during cleaning Open the printer cover and wait until the print carriage stops moving. Remove the cartridge and place it on a piece of paper with the nozzle plate facing up. NOTE: Clean the contacts quickly so that the cartridge is not outside of the printer for more than 30 minutes. If the cartridge is outside of the printer for too long, the ink can dry and clog the nozzles. Unplug the printer. Dip a swab in the clean water, and then squeeze it to remove most of the moisture. The swab should be only slightly damp. Clean the print-cartridge contacts. Do not touch the nozzles. Clean the contacts in the print carriage, inside the printer. Either let the cartridge sit for ten minutes to allow the cleaned area to dry, or use a new swab to dry it. Reinstall the cartridge, plug the printer back in, and close the printer cover. Try to print again. If the issue still appears, proceed to the next step. Step 4: Black cartridges only: remove and rest for two hours NOTE: The following procedure does not fix missing lines or streaked bars printed by the tri-color, photo, or gray photo cartridges, or other color-printing problems. Perform the following steps only if the black print cartridge has printed defective patterns or if you notice non-uniform black text-darkness. In the black print cartridge, this problem might be caused by sediments collecting in the nozzle area. Perform the following steps to solve this problem: Remove the black print cartridge. If the carriage has a latch, re-latch it and then close the printer. NOTE: If the printer is not closed, it cannot adequately protect the remaining tri-color cartridge. Place the cartridge on a level surface with the nozzles up (label down). Allow the cartridge to sit undisturbed for two hours. Reinstall the cartridge and print another diagnostic page. Load letter or A4 unused plain white paper into the input tray. Press and hold the Cancel button and then press the Start Copy Color button. Make sure that the test patterns show a complete grid and the thick color lines are complete. More than a few broken lines in a pattern can indicate a problem with the nozzles. You might need to clean the print cartridges. If the black line is missing, faded, streaked, or shows lines, this might indicate a problem with the black print cartridge in the right slot. If any of the color lines are missing, or if the pattern appears faded, streaked, or shows lines, this might indicate a problem with the tri-color print cartridge in the left slot. Look for defects on the page. If the diagnostic page shows no defects for the black cartridge, and if the cartridge was new, align the cartridge. To align the cartridge, follow the steps: Load letter, A4, or legal unused plain white paper into the input tray. In the HP Solution Center, click Settings , point to Print Settings , and then click Printer Toolbox . NOTE: You can also open the Printer Toolbox from the Print Properties dialog box. In the Print Properties dialog box, click the Services tab, and then click Service this device . The Printer Toolbox appears. Click the Device Services tab. Click Align the Print Cartridges and a print cartridge alignment sheet is printed. Load the print cartridge alignment sheet with the print side down on the right front corner of the glass. Press the Start Scan/Reprints button and the HP All-in-One aligns the print cartridges. Recycle or discard the print cartridge alignment sheet. For aligning the cartridges from the hardware only, follow the steps: Load letter or A4 unused plain white paper into the input tray. Press and hold the Cancel button and then the On/Power button. While the Check Paper and Check Print Cartridge lights are blinking, press the following buttons one at a time in the following order: Cancel , Number of Copies , Paper Type , Color Start If the page still shows defects, go to the next step. Step 5: Replace the problem cartridge If the problem has not been solved by the steps above, either the printer or the problem cartridge is defective. If you have not tried cartridge replacement previously to solve this problem, replace the problem cartridge now. Click here to see if your cartridge is covered under warranty (c00059195). If you have already tried cartridge replacement and it did not help, service the printer. Preventing missing lines Missing lines occur when the cartridge nozzles dry out, or when a cartridge is running low on ink. Do not remove the protective tape from a new print cartridge until just before you install it. Once you remove the tape, do not reapply it. After you have removed the protective tape, do not allow anything to touch the nozzles. Print at least once a month to keep the print cartridges in good working order. Always turn the printer off by pressing the button on the printer control panel, rather than by unplugging the printer. Turning the printer off properly allows it to protect the cartridges. If you are removing a cartridge from the printer temporarily (for instance, removing the black cartridge in order to install the photo cartridge), put it in a cartridge protector. If you do not have a cartridge protector and need to remove a cartridge temporarily, put it in an airtight plastic tub. Make sure nothing touches the nozzles. Do not use a plastic bag. If you intend to store print cartridges in a tub for a long period of time, place color cartridges with the nozzles down, and black cartridges with the nozzles up.

Hi Are you using OEM or rebuilt toners? If your using OEM and your able to smear the ink with your finger more than likely you have a fuser problem?. If your using rebuilt cartridges it could be the cartridge. Good Luck!!

Try to clean the rollers and the cartridges head as they be clogged in ink
which is causing this problem:


# Hold the cartridge upside down, with the bar-code label facing you and take a damp paper towel.
# Use the towel to wipe the printhead of the cartridge on the bottom (where the ink comes out). Wipe the printhead horizontally in one direction only (left to right).
# Continue doing this until it looks clean.
# Then dab the cartridge on the towel to make sure the ink is flowing.
# Next, look inside the printer and locate the carrier that holds ink cartridges. Caution: Make sure the cartridges are not installed at this point.

1. Look for a shiny piece of metal underneath the contacts at the back of the carrier.
2. Take a damp cotton swab (use water only!) and wipe along the bottom of the shiny metal piece. Note: You may need more than one swab.

# Reinstall the cartridges, making sure you snap them correctly into the printer.

What did you clean? If it was the Image Transfer Belt (the big mylar belt in the front), do it again. Print and see if the yellow is smearing again. If it is replace the yellow cartridge.

HP laserjet 5000gn when i print, output smears ink on 2 sides. not a toner issue cause changed toners already. someone says printer is telling me something and might be a warning of


If by smearing you mean the print is also rubbing off? Then you definately have a fuser unit issue. The fusing unit is the assembly that heats up and "fuses" the toner onto the page. When these start to go bad, usually on one edge or the other the print will smear/double image/wipe off of the effected area. One test you can do to verify a fuser problem is to print a page and then when the page is about half way thru the prcess, shut the printer off. Open the top and remove the toner cartridge, pull out the page and see if the lower part is not smeared. Basically what your checking is to see if the print is ok BEFORE it goes thru the fuser. Based on your description I would suspect your fuser is going bad.
Good Luck and Thank You for using Fixya.

Smeared output can result when you refeed a printed page into the printer to make a double-sided page. This happens because the rubber rollers that grip the paper to pull it into the printer can pick up toner from the first side’s printing and smear it. So before replacing parts, this is an easy thing to check. Printing multiple pages consecutively will make the pages print progressively cleaner or you can clean the rollers with rubbing alcohol.

Smeared toner also happens because the nonstick coating on the fusing roller is scratched or has baked-on debris. This can happen if the printer is in a dirty environment especially. If you are comfortable removing the fuser, you can try to clean it with a soft cloth and alcohol, but make sure you let it cool down first!

Finally, if this does not resolve your issue then make sure the fuser is heating; toner that is not heated properly will fall from the page and smear. If the thermostat is bad or the fuser not working properly, you will most likely need to replace the entire fuser assembly. This will be pretty expensive to repair so hopefully it's one of those other issues.

Kids removed a jam, now all prints/copies are ghosted/smear


Sounds like they touched the photosensitive drum. It needs to be cleaned with a cotton cloth. The drum is a lime-color cylinder and it is very fragile. Avoid touching with any object other than the cloth it or scratching it.

Good luck.

Hi xander4265:
I
Streaks in direction of paper travel
There are dark lines running along
the page in the direction of paper
travel from the leading edge to the
trailing edge (B-size print shown).
The printer displays no error code.
Note A-size prints are processed
through the printer with the short
edge of the print parallel to the
direction of the paper path --
making horizontal print artifacts
parallel to the shot edge of the
print.
B-size prints are processed
through the printer with the long
edge of the print parallel to the
paper path -- making horizontal
artifacts parallel to the long axis
of the print.
1. Check the end of life for each of
the consumables by printing the
supplies usage page. From the front panel’s Printable Pages Menu, select
Print Supplies Page.
2. Run the solid fill test pages; From the front panel’s Printable Pages Menu,
select Service Pages, then select Print Solid Fill Pages. If the missing bands
only occur in a single primary color, replace the print cartridge of the affected
color.
3. Swap print cartridges and run another test print.
Note Under some circumstances, streaking may occur in the margin of
SRA3-size paper. This is due to the edges of the paper extending
beyond the end of the imaging components. print-quality in the
margins of SRA3 paper is not guaranteed.
4. Inspect the Accumulator Belt cleaner; replace the cleaner, if necessary.
5. Run the Remove Print Smears routine. From the front panel’s Support Menu,
select Improve Print-Quality?, then select Remove Print Smears.
6. Replace the Developer Housing Assembly (RRP 27, on page 7-171).
7. Remove the print cartridge and (with a flashlight) check for debris along the
edge of the developer housing.

If the toner smears after the page comes out of the printer you may need a new fuser. The fuser is the heating unit in the printer and can usually be seen from opening the back door. Check and see if it has a line worn down the same side as the mark on your pages.
