THIS IS A TONER THAT HAS THE OPC DRUM BUILT INTO THE CARTRIDGE ITSELF AND IS REPLACED AS ONE WHOLE UNIT.  THERE IS NO SEPARATE DRUM UNIT.

 

Not Recognizing

 

Verify they have the correct cartridge for their specific printer model.

 

Samsung has a reputation of doing stealth firmware updates, where they disguise a firmware update as a routine update.  A firmware update may lock out the use of aftermarket cartridges.  Usually when a firmware updates goes through cartridges that were once working will no longer read and/or a cartridge gives an incompatible error and you try others (reships, multiples in the same order, etc) which also won’t recognize.  Try to find out if the customer has done any recent software updates on their printer.  If you notice a pattern, post it on the CSR Blog.

 

There’s a smart chip located on the front top of the cartridge.  Visually check the chip for damage or debris.  You can use a clean, dry, lint-free cloth or Q-tip to gently clean the four gold contact points.

 

Verify the cartridge is being installed correctly and that it is fully inserted into the printer.

Print Quality Issues

 

There is an orange plastic protective cover on the front of the toner cartridge which wraps around and covers the OPC drum.  Make sure these orange protective cover is removed prior to installation.

 

Slowly shake the cartridge five or six times to distribute the toner evenly inside the cartridge.

 

If the toner is smearing off the paper or isn’t adhering properly, make sure the paper settings on the printer match the paper type being used.  Thicker paper, such as labels or bonded paper, require a different paper setting to allow more heating while printing to ensure the toner melts properly to the paper.  Trying to print on thicker paper while under that standard paper setting will cause the toner not to get enough heat to melt properly.

 

The OPC drum is located on the bottom of the cartridge.  Visually check for scratches or debris on the drum.  Do NOT touch the OPC drum.  If need be, clean the OPC drum using a dry, soft, lint-free cloth.  Do NOT use moisture of any kind.  There is no protective drum shutter on this cartridge to protect the OPC drum so caution must be taken in handling this cartridge to prevent damage to the drum.  Be careful with setting the cartridge down on a surface because being that the OPC drum is located on the bottom of the cartridge it can easily be scratched or nicked.

 

Leaking

 

This toner does not have any pull seal tabs and as a result a little toner dust on the cartridge is normal.  Vibrations during shipping may cause the OPC drum to rotate a little and allow a little toner powder to leak.  This is normal.  You can clean excess toner dust off the cartridge by gently wiping the cartridge with a clean, dry, lint-free cloth or gently blowing on it.  Be careful with compressed air as this may blow too powerfully and blow toner powder out of the cartridge.
