I have been unable to print red. The toner cartridge has been replaced and the problem persists

Hello,

Some toner may have spilled in the printer. If so, you will need to clean it out. Also, the toner cartridge may be defective and letting too much toner out at one time, the solution is to replace the toner cartridge.

Take care.

I had a similar issue with my 510. My printer would only print in b&w regardless of my settings in the printer setup. I uninstalled my printer driver and reinstalled a fresh one from disk. This cleared up my issue.

I have to ask this question of you, just to make sure this is not an issue. Are you using a factory new ink or toner cartridge?
Please consider the following:
If you are using a refilled or third party cartridges that may well be your problem. Most manufacturers build logic into their products to prevent the use of “Other Equipment Manufactured” cartridges as well as re-filled cartridges.
They do this to prevent problems from contaminated inks or toner causing problems with print quality or damaging the physical printhead or photo conductors.
If you are using factory new ink or toner cartridges, then please call the manufacturer’s Technical Support for assistance with the warranty on the cartridges

it is a typical new problem for samsung printers. you have to reset the printer. it is a pretty tricky thing to reset this type of printers because you can "blow" it up. try find a local workshop, or a specialized person to do this

Try this

Turn the printer off hold down the menu button turn the printer back on while continuing to hold down the the menu, when you get a green light your ready to print

The following can cause bands (vertical on a normal page)


Faulty Toner cartridge
Faulty Drum Unit
Faulty Transfer Belt
Contaminated Fuser
Damaged or dirty LSU glass

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.

1 Could be toner on the contacts (inside the printer) that mate with the contacts on the cartrdige.

2 Are you sure they are 510 toners and not 500 ones ?? 510 toners have a chip that identifies the cartridge (Colour, Capacity) and maintains a count of the pages printed.
500 toners have a reset fuse that resets the toner counter in the printer, and a resitor that identifies the capacity

3 Are they new cartridges, remanufactured, or 'home refiled'.
if either of the later two, were the chips replaced ? - if not the cartridge still thinks it has printed its full life of pages.
