Hi. Im having problems with the printing, every 4inches or so, on the right hand side of a printed page, the printing is very faded.

Hi,

This could be because of few reasons, The Ink powder is not rotating inside the drum to give you the correct output.

Remove the Toner and Shake it a bit. Try to print.

Check for Firmware update available for your printer. There are Fixes released for known issues.

1.Check for proper driver on evolis site.
2.Check whether both side printing is selected in driver
3.Check for Varnish sensitivity setting in Graphics setting it should be default.
4.Read the ribbon type with Rr command.

you need to take the scanner out (not very easy to do)unless you are a printer tech.
and clean the mirrors.

Im having the same problem
did u find a cure

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.

Hello,

Check out this website it will assist you with all the known printing problems out there,

This could be anything from a transfer roller to a defective ink cartridge. However the above link is for troubleshooting print quality problems with your printer

first u change toner
if problem presist
replace fuser assembly

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.

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

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
