HP has a cleaning page that can be created to help remove toner build up on the fuser roller and I believe one for the drum also. Print "Menu Map" to find the cleaning page quickly. These are the two areas that need to be cleaned to help eliminate the "scumming". I would also look inside the device after removing the print/toner cartridge and if you have the toner wipes, remove any toner spillage inside. please do not use paper towels as they shred too easily and will mess up the transfer roller.
Possible reasons are: 1.empty toner cartridge, 2.dirt under one of the toner cartridge's developing roller, 3. dirt on the primary charge roller in the drum cartridge, 4. obstacle on the laser path.
Replace the empty toners first and try printing again. Follow the next steps if it didn't solve the problem.
Print a test page with 4 stripes across the page - black, cyan, yellow and magenta. See if all have the missing toner line or only one of them. If the white stripe is going trough only one color, inspect the cartridge with that color. It has to have the same stripe on the developing roller. See if there is some dust beneath it that makes the stripe and clean it with a brush. If the stripe is across all colors, then inspect the drum unit. The drum itself has to be evenly shining on the light. If there are uneven matte tracks on it, consider replacing. There should be a gap somewhere for the laser beam to pass and the drum is visible trough it. Look trough it for obstacles like piece of paper or hair. The primary charge roller has to be close to that gap inside, touching the drum. Look for dirt on it. Clean if possible.
Toner cartridges last approx. 6500 pages. The drum cartridge lasts between 14 000 and 28 000 pages depending on the color use.
Possibly a full waste toner container. I had the same problem, took pout the waste container, tilted it and tapped it to get toner away from the sensor window, and then it printed perfectly. I will empty the container ASAP before it overflows.
If you have BLACK Marks on the paper the YELLOW roller does not need to be cleaned usually.
To clean the yellow toner off the roller use a DRY lint free cloth. For this issue my suggestion for a resolution to the Yellow toner issue is replace the toner. They are not supposed to leak in the first place.
As for the BLACK tone on the left of the page you most likely have a Fuser issue causing that.
I know you've tried some of the below suggtions but I put the whole list there for everyone else. If this printer is less than a year old call them. Their tech support has changed a lot! They try to take care of you.
·Check/Replace the toner cartridge ·Check the charge roll assembly (see Note below) ·Check the Toner Darkness, Brightness, and Contrast settings ·Try cleaning the inside of the printer ·Bright light/sunlight entering the printer (on right side of printer) ·Printing on media other than plain paper (make sure you're using laser paper- it makes a difference!) ·Using a refilled cartridge.Lexmark will emphatically tell you they are not supported.
NOTE: Checking the charge roller: 1 Power off the printer and remove the toner cartridge. 2 Look into the upper area of the printer where the cartridge was sitting. Located near the top of the printer you will see a couple of gray rollers. This is the charge roller assembly. See the area highlighted in the image below. NOTE: If you cannot see the rollers, close the upper lid slightly and the rollers should lower into view. For larger version of this image, click here. 3 Make sure the roller assembly is seated correctly into the holders on the left and right-hand sides. If not, try to reseat the assembly into the holder arm. IMPORTANT! If the charge roller assembly is not present, it needs to be installed. Look around the inside of the printer and near the printer for the roller assembly. If the charge roller assembly is missing, you will need to order a replacement set in order to get the printer operational again. See the 'Additional Assistance' section at the end of this document for more information. 4 If the rollers are present and installed correctly, check their condition. If the roller surface appears dirty, take a clean dry cloth and carefully clean off any dust or toner. Do your best to ensure all of the roller surface is clean.NOTE: If any part of the rollers is damaged, the charge roll assembly will need to be replaced. CAUTION! Try not to touch the rollers with your bare hands. The surface is susceptible to contamination and a permanent mark could remain on the rollers. 5 If you were able to reseat the charge roller assembly or managed to clean the rollers, power on the printer and try printing again. Print 10 to 20 pages to give the pages a chance to clear up. If the pages do not begin to clear, the printer will likely require service to correct the issue. For more information on arranging repair service, please contact Lexmark Technical Support or an authorized service center. See the 'Additional Assistance' section at the end of this document for details.
1. Remove the paper tray and look inside the printer on the upper part and you see two rubber feed rollers, (they should be a white color) if they have toner on them that could be one of you problems,you would have to clean or replace them if they are worn.
2. you can run whats called a half test, print any document and while the document is printing open the front cover when you think that the paper is under the toner cartridge so the printer will stop. look at the printed page to see if the mark is there. If the mark is not there than you have a problem with the fuser assemble.
Laser printers do not use Ink. The problem is most likely a defect on the drum, which in this model printer, is part of the toner cartridge. Replace the black toner cartridge with a known good one and test.
Hi, Sounds like your problem is not the rollers. If its marked on the pages, its not the pickup rollers nor the Exit rollers that leave marks.
Either 1 you have a bad Toner Cartridge. or 2 Fuser sleeve is bad and needs to be replaced.
(1) If the toner cartridge is refurbished that is your first indication that you should replace with a HP Manufactured Toner. Refurbished toners always go bad. In fact many of them do not even last the amount they are said to last.
(2) If its not the toner cartridge, then the only other thing that is fusing roller marks is the fuser. In order to do this. You will have to remove the back panel. Unscrew the fuser.*note fuser can be extremely hot after use. be careful.* From this point you should be able to look at the Fuser sleeve and see a worn out sleeve on the side which your roller marks are at. You will either need to replace it if it looks bad. Or you can clean it when its got with a piece of paper or an alcohol pad to remove excess toner clocked on the fuser.
That toner is whats showing up as roller marks on your prints.
