Question about HP LaserJet 4350TN Printer

1 Answer

Dirty copies We have a HP 4350 tn at work and the copies are dirty down the middle of the page. We have run the cleaning option and this has not cleaned it. We replaced the cartridge and this did not help. Does it have a drum that needs to be replaced? Is there paper that can be run through it that will clean it? Help!

When you replaced the drum did you printed like 15 pages? Did you noticed any change in the ouput of the line did it fade?, if you are 100% sure that the cartridge is ok., then check the fuser and/or the transfer roller. Make sure that the printer is clean inside.

HP Laserjet 3330 printed dark page especially around the middle

Does this happen both when copying and printing?
For printing solution, try another toner cartridge.
If lines continue to appear when copying (primarily through the automatic feeder) then lift the auto feeder, and clean the glass -mainly the narrow piece on the left side.

please rate solution :)

HP 3050 vertical black lines during fax

OK, from the desciption i can assume several things here are some option.
If by receipt you are talking about the confirmation the unit prints the the problem is likely dirty glass.
You would also get the lines when you make a copy using the ADF.
Open the lid there are two areas of glass the thin strip is likely dirty and needs to be cleaned.

If by receipt you mean pages you receive from someone else, and not printed or copied on your machine, then their machine has the condition described above.

If everything has the lines then you have a toner or fuser problem:
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 but NOT the fuser.
If the page is clean the problem is most likely the fuser.
Hope this helps

Black line going down the middle of the page

lift the auto feeder and clean the scanner glass that your pages scan across -it is dirty. You can make a copy afterward and this will tell you if you have solved the problem.

Paper has dark marks down middle

If you make a copy, does the copy have dark areas down the middle of the page? If so, remove the toner cartridge and gently roll it around to redistribute the toner inside, maybe even replace the toner cartridge if you've had it a long while. If you still see unevenness, you may need to have the machine looked at.

If the copies you make on your machine look fine, then I would suspect that the person sending you the fax has a dirty scanning element. Check with them to see if they can clean the scanning element and it should improve the fax quality.

I will give you all the reasons I can think of.
1, If the line is only there when running through a document feeder and not there off the glass. The small strip of glass directly under the document feeder is dirty.
2. The drum has a scratch on it, or the cleaning blade is not cleaning the drum properly. Would require that cartridge replacement.
3. The fuser roller may be work in the middle. You would notice some reprinting , or ghost copying if that were bad.
4. Less likely would be some piece of fuzz in the light path, or a small piece of paper or tape in the paper path smearing the ink across the page.
If your machine prints, see if the line is on a print, if its on a print and not on the copy then it is scanner related.
