Question about Samsung CLP-510 Laser Printer

Toner and Imaging Unit issues

Replaced imaging unit but continue to receive intermittent replace messages. Also, just started getting replace toner messages even when the toner cartridges are new. Unable to use printer when these occur.

This morning it first said "replace black toner" even though I had just put a new one in recently. I had another, so I replaced it and then I had a "replace magenta toner". I did and then it said "replce cyan toner". I did and then it said "replace black toner" again. Very frustrating.

Re: Toner and Imaging Unit issues

If this IS a CLP-510, first make an information confirmation print.
Press MENU, then press ENTER, and ENTER again.

Look at the counter for the imaging unit, is it a low count confirming that you have indeed replaced it ?
If not you will need to reset the counter.

Check the counters for the toner cartridges, and check the capacity of the cartridge. On a CLP-510 the image counter for the toner is held on the chip on the cartridge (which also identifies the capacity of the cartridge).

There have been some faulty (oiginal Samsung chips), and of course re-manufactured cartridge chips could fail (many re-manufacturers don' test their cartridges before dispatch, they don't have the facility to do so without starting the count on the chip (or 'bowing' the reset fuse on a CLP-500 cartridge). VERY few re-manufacturers can test these cartridges without starting the count.

Sometimes the 'replace xxxxx toner' messages are caused by toner on the three contacts on the side of the cartridge, or their mating contacts inside the printer. Rarely, this can be caused by a faulty circuit board.

If the message Change Imaging Unit Magenta displayed refer to imaging unit with contents a developer.The Imaging unit life is 80.000 copies.
The imaging units located after front door when is located the waste toner box.
If the message M toner end/change the M toner displayed refer to toner cartridge
The toner cartridge life 15.000 copies 5% saturation.In full color mode the color saturation is 80% and the color toner life is 6.000-8.000 copies.
I think your problems is a toner not the developer.

The printer did not reset when we replaced the black toner AND the imaging unit

Hi this issue may be casued because when you replace the toner and imaging unit they must be new and not taken from another machine i am sure if you put a new out of the box toner and drum unit out of box it will work

I have a clp500 with vertical fading on the b&w. I have replaced both the transfer belt and the imaging unit (@ 25000 copies) and am still getting the fading if the printer sits idle for a period of...

Sounds like you may have wet toner, or was once wet toner. Ive worked on printers for years and I have actually found a few cartridges that had bad toner. Kind of like getting sugar or flower wet.
Also. sometimes the imaging unit won't charge the roller properly or the roller gets worn (I.E. Static Charge holds the toner to the drum until it is applied by the imaging unit)
So if you've replaced the imaging unit, then it almost has to be the toner itself or the toner drum. They are both part of the cartridge and the problem should go away if you replace the cartridge.

Good luck

Large Toner Streak... Bad Imaging Unit?

Check to see if you waste toner recycling for the cyan is working or being blocked. Check the transfer bias roller next to the cyan drum. Return you cyan imaging unit for a warranty replacement. Check for obstructions to the cyan developing unit. Check that the cyan IU was put into the machine properly. Check for toner leaking from the entrance to the developing unit or from the toner cartridge.

or, call a qualified KonicaMinolta tech to check out and service your machine.

Yes, but be careful about where and how you dump the toner. It can make a real mess!

Samsung CLP 510 Imaging Unit

The Imaging unit needs to be replaced when the drum fills up with waste toner. That's what triggers the message.

Magenta cartridge empty

When you take the toner cartridge off the imaging unit, is there magenta toner in the open slot of the IU? Assuming that there is nothing wrong with the toner cartridge, you are possibly looking at a bad engine control board.
