Question about HP LaserJet 4350 Printer

1 Answer

Print fading down right hand side

We have an ongoing problem with a HP4350. The print is faded down the right hand side of each page. The left hand side of the page is fine but towards the right hand side the image gets steadily weaker and almost vanishes. We have tried various toners including original & remanufactured replacements without change. We also bought and used the maintenance kit for the machine but no change.

Any ideas what might be wrong?

    I have the same problem, brand new toner, brand new maintenance kit. Fading on the right side of the page.

    Hi,



    We have, as described, removed the top etc and the laser unit, turned over and cleaned the mirror under the metal flap however the problem persists. Is it possible that the lasers may have attracted dirt. Looking in the reflection of the mirror everything appears clean inside the unit but it would make sense that the problem is in there somewhere.



    Thanks

I was able to fix it by taking off the top of the printer. This involved taking off 4 screws on the top of the printer. I then had to disconnect the wires going to the control panel by unhooking them from the right side. I then located a thin rectangular box which I'm assuming houses the laser. I removed this with 4 more screws and turned it over. There was a little metal flap that I moved back and below was the mirror the lasers shoot on before going onto the toner.

In the same spot where I was having fading, I noticed a lot of toner on the mirror, so I cleaned it of, put it back together, and the fading was gone.

This was after I tried a new toner and maintenance kit.

Hope this helps

Faded print on right side of page. When I copy/print in black, why is the black print faded on the right side of the paper?


Your toner cartridge may be the culprit.
Take the cartridge out and shake sideways and up/down. Reinstall it and try again.
If it's still printing faded side, replace the cartridge.

Print quality: dark faded, but continuous


Open top cover and remove toner, shake toner cartridge and try a test print. IF image good then problem is low toner level in cartridge.

Could be the fuser, or the drum is not getting the charge on that side.

Print on left hand side of page is faded as you look to the middle and right hand side of page print is clear


Place one hand either side if printer,
Gently shake the printer left and right a few times without lifting it off the desk..

What happens is that when a laser printer is moved and is not kept level the toner will move to one side or the other, the gentle shake evens out the toner.

It might be a dirty led assembly. The leds hang down from the top when it is opened.

I have Hp color laserjet 2600n -when i print a color document, the left hand side of the page is faded, the middle and right hand side of the document prints fine. Internal documents print perfectly- this...


According to HP if the problem is only when you print from your PC or Mac then you need to reinstall the printer driver. If the problem is also when you print just from the printer, i.e. scanning or test page, then the problem is with the printer.

Magicolor 2400W - Printing Problem


check the green levers at the top of the fuser unit that have envelope icons on them.  They reduce pressure on the fuser assembly for thick stock.  It is possible that one side is up the other down, causing uneven pressure across a page.

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
