First thing I would do would be to make sure you are using HP genuine toner. Generic or 3rd party toner cartridges tend to fail about 50 percent of the time. If that doesnt solve it, the next step would be to make sure your firmware is up to date. Print out a config sheet and it will tell you the firmware version, which goes by dates. The older the date, the more likely that it has new updates since then. To update the firmware, go to the HP website and go to the support tab to find the version for your specific printer. Hope this helps.

SOURCE: three broken horizontal lines across all printed pages

I can see a couple of possibilities here. One: The cleaning blade for the drum could be damaged and not all of the toner is being cleaned off of the drum between pages. Two: The drum could be damaged and the damaged parts of the drum are not accepting the changes generated by the laser. I don't think you have a fuser problem because if it were that, the toner would probably smear when you touch it. Typically, I would say it is the toner cartridge but you replaced it and still got the same problem. I would inspect the drum cleaning blade first. That would be the most cost effective first option. Hope this helps. Good luck.

you probably needt o change the transfer belt which is the "black roller film". you can try wipping it off with a dry lint free cloth.

Hello,

This issue can be due to fuser. I am sure you have changed the toner cartridge.
To confirm its a fuser issue, please perform the following:
1. Try printing a configuration page from tray 1, pull the top cover, as soon as the media is 60-70% inside the printer.
This would stop the paper before reaching the fusing assy.
2. Remove the paper and check if the line exist.
If exists, fuser is not faulty.
If it does not, then transfer roller, laser/scanner assy is faulty

- If fuser is faulty, perform the cleaning page as following
1. go to configure device > print quality > create/process cleaning page
perform cleaning page 5-6 times, however, if the line is due to fuser, then fuser needs to be changed.

Let me know the next update.

SOURCE: light grey vertical line

Hi there,

I believe there are 3 possible causes for this issue; toner drum, fuser or transfer roller - more than likely I would dismantle the printer and check for lines on the fuser. But just in case remove the toner and carefully release the flap to reveal the toner drum - if that is scored and the lines correspond to those on the print-out thats the cause.

the two places to look is transfer roller and the fuser unnit.
i think there is a problem with the transfer roller it is under the toner and it needs to be spring loaded. The paper passes between the toner an the transfer roller to charge the paper en let the toner stick to the paper and if it doesn't make correct contact then it wont work

Dark lines appear on each page I print on the printer. I have cleaned every roller, dumped the old toner and added new toner.


Are the lines vertical or horizontal?

vertical lines can be caused by several things.
Since you said that cleaned the rollers, then here are other options
1: Most common is a bad toner cartridge.
2: try cleaning the fuser entrance guide.
3: could be a defective formatter - formatter replacement the fix.
4: worn fuser. fuser replacement is the fix.

horizontal lines are probably repetitive down the page, and are usually caused by a defective toner cartridge or fuser assembly. occasionaly a transfer roller will cause it as well.

Toner loves to get baked onto the fuser and cause all kinds of print problems. Not much you can do but to replace the fuser when this happens.

Vertical streaks when printing pictures


vertical lines on prints usually means either the drum's cleaning blade is not cleaning the drum (or the drum is damaged) or the fuser is scored. scored means that the protective coating on the fuser rollers is damaged. I would check the rollers on the fuser (the hot part of the printer right near the paper exit) for any lines on it, if you look at your prints, you should see them in the same location on the fuser. if you do not see any lines on the fuser rollers, then replace the drum.

Hp 4550 vertical line down center of page


From the service manual:


Vertical lines or streaks
 Check for a leak where light might be entering the printer.
 Check for circumferential scars on the photosensitive drum. If scars are present, replace the
drum cartridge if the line goes through all colors.
 Check for circumferential scars on the upper fusing roller. If scars are present, replace the upper
fusing roller if the line goes through all colors.
 Remove the imaging drum and inspect main charger or imaging drum for a contaminant, such as
a fiber, if the line goes through all colors.
CAUTION Do not expose the imaging drum to light for more than 15 seconds. The drum is light sensitive, and
exposure to light can cause permanent damage.
Vertical black lines
 The toner cartridge is defective.
 The toner cartridge is not seated properly.
 The fuser entrance is dirty.
 The fuser has scratches on it.
 This might be a repetitive defect. If so, the lines will repeat at a consistent interval down the page.
 The printer needs to be cleaned.
 There is a problem in the heating element.
Vertical white lines
 If white lines or streaks appear only in the black areas of the printed media, print several
configuration pages to clear the anomaly. If this does not clear the problem, check the sleeve
surface to confirm the defect, then replace the black toner cartridge.
 If white lines appear only in a particular color, try printing several configuration pages to clear the
error. If the error does not clear, check the sleeve surface to confirm the defect, then replace the
defective toner cartridge.
 There is a lack of toner or the toner cartridge is faulty.
 There is dirt in the laser path.
 The fuser is defective.
 A mirror in the laser scanner is dirty.

Streaky smudges vertically down middle third of each page


NOPE - don't even try to do this - Replace the entire fuser, these have a film roller and it's not worth trying to rebuilt - replace the fuser and you should be fine, To take the top off is a pain , the fuser sits on top of this Printer so it's difficult- either call a Color Printer tech or buy a rebuilt fuser , I wish i could give you our company info, however, i been informed not too Sorry , fixya.com rules not mine.

Faint grey lines Every 1/3rd of a printed page


This is the test to determine toner or fuser issue.
Print a test page
When you hear the paper feed into the machine open the top to stop the machine
Remove the toner cart.
You should be able to see the page with printing on it. (This is before the page hits the fuser)
If you can see the smudge or marks on the page the problem is most likely the cartridge or cleaning roller but NOT the fuser.
If the page is clean the problem is most likely the fuser.
