Faded Stripe in the middle of the page

When we print a page, and when we send a FAX, there is a stripe in the middle of the page that is faded. We have replaced the ink cartridges and this has not solved the problem. The whole page is not light or missing ink, only the stripe in the middle. Is there a part that we can replace, or can you tell me how to fix this problem?

You need to clean the drum When I was working for the City There was the same problem with the Laser printers. Check the Manuel and see if there is a page on cleaning the print drum on your machine. Also you may try Talking the cartage out cleaning there as well It seems you are picking this up form somewhere after the print My Guess would be the print drum? You may also have to replace the drum as well. I am guessing that this is a laser printer? if not then there are other solutions.

Everyone will tell you that it's the Imaging Unit - happy to say that's not true. If it was the imaging unit the colors would not come out right either. I bet if you print a test page that all the colors come out fine across the page. It's only the black.

Also - if you replace the black toner cartridge, or reinstall your printer and drivers like some people will tell you - still no results.

The problem is in the black toner cartridge PATH inside the printer. Something has jammed it up a bit. Try taking out the black cartridge and blowing firmly into the small hole at the bottom of the spout that looks to have a sponge inside. Use a straw and make sure your air blown is dry. Then lightly tap the cartridge a few times. Then use the straw and once again blow very firmly inside the receiving path (inside the printer) for the spout on the cartridge. Make sure you are blowing into the spout path at the bottom - not the gear drive path in the middle - as that will not do any good.

Replace the cartridge, warm up and print another black and white page. You should see that the faded out section is gone or diminished in size. If it is not gone, simply repeat the above steps until it is gone. You will see that the faded out strip gets smaller and smaller each time until it's gone. I had to repeat five times, but eventually got it corrected. Now prints like brand new so don't get discouraged.

Faded stripe down the printed page


I found a solution that worked to eliminate the faded black stripe down the page thanks to a post by slamfix in another forum. The problem is related to ink build up on the blade edge of the black developer assembly in the imaging unit (the imaging unit contains 4 separate developers - yellow, blue, magenta, and black). The solution involves taking out the imaging unit, removing and cleaning the blade edge of the black ink developer until smooth. It took me about 15 minutes to complete and was fairly straightforward.

What you are describing is a bad print head. You can try running the eliminate light stripes several times, and jet substitution, but most likely the print head will have to be replaced to remedy your problem.
You can try googling. Phaser printer print heads or phaser printheads.
There seems to be a secondary market appearing for those print heads. I can tell you from Xerox, if you have no maintenance agreement, they cost $750 per print head.
Honestly, having worked on about every type of color printer known to man, the new solid ink phaser printers, produce a dry ink image of 2400 x 2400 dpi with ink particles that align end to end. The resolution of those printers are remarkable and can be purchased for less than the price of one of those new print heads.
Now for reliable, albeit somewhat not as sharp a color image, but still exceptional, you really can not beat an HP.
The ink stick technology really no longer has the color vividness advantage it initially had. The inks that align end to end, have ended that advantage and are sure a lot cheaper to operate per page.

Intermittent blank stripe down Right Side of page


Open the top cover, lift up the PCU lever & remove the PCU. Rotate the carousel (Toner holder) by hand and check that all of the toner levers are locked down fully. Check if any of the toner levers are loose and possibly moving as the drum is rotated. There is a small clear plastic flap below each cartridge, it is possible that one is fitted incorrectly or even missing allowing toner to leak past and fall on to the laser lens thereby blocking the laser and causing these symptoms. Hope this helps.

Faded print on one side of page


I have a SCX-4100 Samsung, replaced the tonger cartridge, it was working fine for a few hundred sheets of printing, but after that, the left side of the page was printed very light, faded.
If I run the "Clean Drum", it will print a litter better, but still faded.
What can I do to correct this problem?
Thank you
