If replacing the toner cartridge didn't work, then the fusing unit is probably broken or not getting enough power. replace the fuser.

Consistent dots down print


Try to print clean page ,
Print a cleaning page During the printing process, paper, toner, and dust particles can accumulate inside the printer and can cause print quality issues such as toner specks or spatter, smears, streaks, lines or repeating marks. Follow these steps to clean the printer's paper path.

  2. On the printer's control panel, touch the Menu button.

I have a hp color lj2600 that is creating double image on printouts. but if i printout a cleaning page it begins to reduce the double imaging. can the fuser cause this type of problem?


It may be the fuser, but if it is really it, then you should be able to notice some spots/lines that are there all the time, no matter what you print. I'd go for a magnetized corona, that fails to demagnetize the transfer roller.
Open up the printer, get to the print assembly and try demagnetizing the transfer corona (there should be a plastic bezel that slides along the rollers), or if nothing else then get some aluminum foil wrap it alongside the roller and touch the foil onto a metal part of the printer, to get it to ground the electric potential buildup.
Or it could also be the brushes that scrub the transfer roller clean from the residue toner. See if the excess toner tank is full. If it is full then it's the corona. If it's not full and you can see toner dust all over the printer then it's the brushes that fail to scrub off the toner in time.
Either case, you may be looking at a new print assembly purchase real soon.

Quilt y of print !, it gives double printing on page one is print of original doc.& second as its image what should i do to improve its print quilt y. i will be thank full to you


Hi,
Dots, Lines, shadows and smudges on the printouts are due to dirty/ deteriorating cartridge and cleaning the green drum of the cartridge may help temporarily. Take out the cartridge and gently clean the roller/ green drum with a dry, soft, lint-free cloth wiping off the toner dots marks/ lines.
Also, make sure that the visible inside of the printer is clean and ther is no spilled toner inside, which sometimes results in dots. Double printing is also due to the deteriorating cartridge. The drum is not getting clean after its each rotation and hence the remaining toner/ image is transferred to the paper resulting in double printing. So, it is recommended that clean the drum etc (this would help temporarily). Also, make sure that the toner cartridge is in good working condition. If not you may replace the cartridge.
Let me know if any further clarification/ assistance is required.


GoodLuck!
Dont forget to appreciate the solution if I could have been of any help!

Hp color laserjet 2600n is printing lighter on one side of paper. Where light is also printing shadows down paper of letters at top.


First of all you may have 1 or 2 things going on here. First of all the HP2600 series is prone to having the laser optics get toner dust on them which causes light prints usually on on side or the other. If your light print on one side is on black and all the colors then it may be the fusing unit. Another indicator of the fuser being the cause is the double imaging.....meaning something that is printed at the top of the page gets re-printed farther down the page. Does any of the print, especially on the double image/light side rub off? If so then it is definately the fuser. In case you don't know the fusing unit is the part that heats up and "fuses" the toner onto the paper. It is located right where the paper exits the machine. You can try a test for a fuser problem by printing something then shutting the printer off before the paper starts to exit the printer. Open up the printer and look at the sheet being printed. Is it light on the one side before it goes thru the fuser? If so then you need to clean the laser optics. If it is not lighter then this will prove the fuser is the cause. You can find the fuser units all over the net and they are easy to swap out. As far as the laser optics go you can try the basic cleaning yourself by removing the 4 toner cartridges. Behind these units you will see kind of a large black box with 4 evenly spaced "slots" running from side to side. Inside these slots is a plastic lens that the laser beam goes thru on it's way to the toner cartridges. Just take a cue tip/cotton swab and clean these 4 slots. Once clean just re-install the toners and test to see if the print quality issue is improved. Sometimes the whole laser box assembly must be removed, dis-assembled and cleaned. I recommend you hire someone to do this as it can get a bit much if you do not have experience with these machines.
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.

there should be an option for auto cleaning the printer, if you can't find it, look in the manual
use just regular or construction paper, it will most likely take a lot of sheets of paper, so don't use the fancy expensive type

My problem with the Lexmark optra sc 1275


Lexmarks use a silicone oil cleaning pad on top of the fuser, try to locate a door on top towards the rear, take it out you might see a long black piece, when you take it out it has a felt on the bottom it is used to clean excess toner off the fuser it should be replaced everytime you change your toner ( usually comes w/the toner).

Double print or a shadow print


Unfortunately your drum unit is shot. The mechanism that cleans excess toner from the drum surface is worn out or has developed a problem. The materials needed to repair are generally not available. If this is happening then the surface of the drum is probably near the end of its usable life anyway. Save yourself a lot of grief and aggravation. Bite the bullet and buy a new drum unit. Office Depot, Staples, etc. usually offer them at about $105.

Cleaning a laser printer can solve minor problems, maintain print quality, and prolong periods between professional cleanings. Clean your printer when print quality deteriorates or when you change toner cartridges. Manually Cleaning Inside the Printer Steps: 1. Unplug the printer from the surge suppressor. 2. Remove the internal paper trays. 3. Remove the toner cartridge and place it on a piece of scrap paper. 4. Clean inside the toner cavity with a dry, lint-free cloth and brush (if a brush is supplied with the printer). 5. Clean the printer mirror gently with the brush. Don't touch the mirror if a brush isn't provided. 6. Wipe away dust and spilled toner. Remove paper fragments. 7. Clean the rollers, but don't touch the sponge roller. 8. Replace the toner cartridge. Tips: To remove unfused toner from the rollers following a paper jam, print 5 to 10 blank pages on scrap paper. Wipe toner from clothing if necessary, then immediately wash toner-soiled clothes in cold water. Go to your printer manufacturer's Web site (see Related Sites) for detailed cleaning instructions. Warnings: Don't use any liquid cleaners inside the printer. Initiating Automatic Cleaning Through Printer Software Steps: 1. Open the printer software by double-clicking on a printer icon or specific printer utility program, or opening a document and then selecting Print from the File menu. 2. In the printer software, look for a button labeled Options, Troubleshooting, Toolbox, Printer Utilities or something similar. (This varies by manufacturer.) 3. Follow the instructions on the screen. 4. Repeat the cleaning process if the results aren't satisfactory.
