CLP 510 very light print

Hi,
I had same problem of light printing and I solved it by cleaning High Voltage Power Supply(HVPS) circuit board. My background is electrical,so I tried and got success. Please note that this board has high voltages and Precaution is required to handle these HVPS. Goodluck.

Hello guys i post earlier, that i have the same problem. My father have exact printer, so i flip Toners, Belt, Imaging. Same shit, prints too light on my printer with his parts, and prints ok on his printer with my parts. So i called Samsung they said that probably its worming up, and printer out of warranty SHIT.

Just to determine the problem could you tell did you use color glossy laser paper? Becaue i did and they told me that this printer is not designed to pring on color glossy paper but there were no worning about this.

In the end I changed everything possible and it still printed exactly the same. I rang Samsung and as it is out of warranty, they said it would be cheaper to buy a new one.

On top of it as the model is no longer available I know have new toner and rollers for a machine that I will likely have to throw away!

What a mess!!!

Hello im sorry but did you have change to fix this problem because i have exactly the same one, thank you

Did anyone do anything to the printer immediately before the problem started ??

The description of the printout is typical of what you get whenthe transfer roller (black foam roler with purple plastic lugs on the ends) is either not in the printer, or not fitted properly.

Open the duplex door (opposite end to the toner access door, and you should see this component. If it's missing (or damaged) they are available on EBAY.

There are other possible causes such as

dirty (toner contaminated) contacts on
Toner cartridges
ITB (Transfer Belt)
Imaging Unit (OPC Drum)

This can also be a faulty Drum, faulty ITB, or a fault on the HVPS board
