With the toner, go ahead and shake it in a back and for motion so that way the ink goes all around and doesn't get stuck. Then try printing again.

Black smudges down left side of page


How do I clean white or black spots on printed documents? Description: First make 10 to 15 copies of a blank, white sheet of paper.
If you still see the spots on printed documents after making multiple copies, clean the drum unit as follows:

  1. Remove the drum unit and toner cartridge assembly, and then remove the toner cartridge from the drum unit.
  2. Position the print sample in front of the drum unit so you will know the exact position on the drum that is causing the poor print.
  3. all-ug-19.gif
  4. Turn the black gear on the drum as you check the surface of the OPC drum.
    The OPC drum is photosensitive so do not touch it with your fingers.
  5. all-ug-20.gif
  6. When you find the substance on the drum surface that matches the print sample, gently dab the surface of the OPC drum with a cotton swab that is lightly dampened with isopropyl alcohol.
  7. Note
      • Do not use a scrubbing or wiping motion because this might damage the drum.
        all-ug-21.gif
      • Do not try to clean the surface of the OPC drum with a sharp object, such as a ball-point pen, because this might cause permanent damage to the drum unit.
  8. If the print quality still has not improved you need to install a new drum.

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.

My hp1012 is printing dark with shading on the pages and shadow or echos. Can something be replaced or fixed?


with this issue, you pretty much have to run a half way test unless you have the convieniance of another toner to try. basically, it's either going to br your toner or your fuser and a halfway test will determine this if you don't have another toner to try.

The Half-way Test

You will need to print a page and open the toner lid when you think the paper is underneath the toner cartridge. This will stop the printing so you can pull the toner cartridge out and look at the partially printed paper. It may take a few tries to time this test correctly so the paper stops under the toner but not completely into the fuser.
1. Print a test page from Tray 1, the "fold-down" Multi-Purpose tray on your printer.
2. Just as the test page completely disappears into the printer, open the toner lid door. The print job will stop, sensing an error.

3. Pull the toner cartridge out, and you will find the test page sitting directly underneath the toner.
4. Carefully remove the page by gently pulling the page upwards & free from the toner cavity. Careful! The toner has not yet been fused to the paper, so the print can be somewhat messy on your hands and may smudge easily.

Examine the printout.
1. If you do not see the print defect on your test page, that means the defect is being added later in the print process by the fuser. Fusers are the main component in a maintenance kit; click here to view our selection of maintenance kits for various LaserJet printers.
2. If the print defect is visible on this printout, that means the print defect is occurring before the fuser. Try replacing the toner cartridge (click here to view our selection of toner cartridges).
If you determine the print defect is occurring before the fuser, and swapping toners doesn’t fix the problem, there could be several things causing the problem. In the order of most likely to least likely: you could have two defective toner cartridges, the transfer roller might be faulty, the laser scanner could be dirty or defective, or the high voltage power supply could be bad. You might want to email or call since these scenarios are not as common.

HP laserjet P2015 is printing blank


Are you getting toner on the paper? To find out, print a test page. When you judge that the paper is under the toner cartridge, turn the printer off and look at the toner cartridge. Is your document displayed on the toner drum in toner? Is there toner on the paper?

No No Replace the toner cartridge. If that doesn't work you have more serious problems.

Yes No Replace the transfer roller.

Yes Yes If toner is smeared on the paper, replace the fuser.

Black spots lined up on page - cleaning sheet didn't help


To tell if it's the fuser you can do a half way test, what you have to do is print a document, and open the front door of the printer to stop the print job half way through, you should see that half of the toner is fused to the paper and half is just applied to the paper, if you see the black lines on the fused side of the page its the fuser if you see it on the entire page it could be the etb or the cartridge.

possible fix:

This is a common issue with laser jet printer,

Try running cleaning modes under the service menu on the printer, run 5 back to back. if the issue is still showing, try using a different cartridge and run the cleaning mode again. If you have an old cartridge even if its close to being empty you can do an override on the printer to test the cartridge:
1.press ok
2.use the arrows and navigate to the system set up menu
3. press ok
4. print quality
5. press ok
6. override out
7.press ok and again ok to set

This could also be a build up of toner in the fuser assembly, and you may have to adjust the fuser temperatures in the embedded web server. You can print a blank word document (20 pages) and see if you still see black dots, if you do it is likely to be the fuser, set the driver and printer settings to card stock or heavy in order to heat the fuser more than the usual temp and print 30 blank pages this should resolve the issue. if this does not there could be damage to the ETB or the fuser assembly and servicing of the printer would be required.

take care,

Al

HPlaserjet P1006 Series When printing getting a white blank streak down the middle of the page


To isolate the problem you need to do a 'half test'. This involves printing and stopping paper half way through the printer. This can be done by opening the toner door at the appropriate time. The paper should have just entered the fuser (watch out, the fuser is HOT). You should see the paper with the printing on it after removing the toner cartridge. Carefully turn the toner cartridge over and move back the door that covers the drum. DO NOT TOUCH THE DRUM. If there is the corresponding blank spot in the center of the drum, like the paper, the scanner is dirty or blocked. A can of compressed air will help here. If you have access to a different toner cartridge, you may want to try that first.

Ruppled printed paper cannot exit output tray


you need do follow steps:
1) check fuser unit, the fuser hot roller is hot or not? if not the fuser heater fail.
2) check hot roller should spin with the pressure roller which is against hot roller, and check there is no gap between them, and also nothing pieces paper obstruct there, because if it losts pressure balance that jam should be occured there.
3) check the output roller after fuser unit(if there is), check them are spin or not, this roller kit use for pull the paper goes out the tray. if not spin means the roller drive belt or gear loosen.
3) check paper sensor that is micro swtch around pulling roller or output area and to clean it (could be a optical sensor).
hope help you something fixed, please take a rating let me know how much helped you thanks! keep in touch your question
