The TN650 toner cartridge and DR620 drum unit are two separate units that are sold individually.  The drum unit generally needs replacing after 4-6 toner cartridge changes.  When replacing the toner cartridge the old drum unit MUST be separated from the old toner cartridge and re-used with the new toner cartridge unless a new drum is being installed as well.

Our TN650 is a universal cartridge that is used as a TN560, TN570, TN580, TN460, and TN650.  This is also the Konica Minolta TNP24.   It will come packaged as a UNIVTN460 or UNIVTN650.

 

Not Recognizing

 

Verify you have the correct toner cartridge or drum unit for your specific printer model.

 

The toner cartridge uses a flag gear to hit an actuator inside the printer and reset the page count for the toner.  Be sure that the cartridge is fully inserted into the printer.  Also, try removing and reinstalling the toner cartridge.

For toner life end errors on the Brother HL series printers you can try to reset the toner life by doing the following;

1. Open the Front cover
2. Press and hold the GO button
3. Power ON the printer while continuing to hold the GO button
4. Once the 3 LED’s are lit, release the GO button
5. Press the GO button 2 times. This will cause the LED’s to light solid
6. With the LED’s lit solid, press the GO button 5 times
7. Toner Life End will then reset
8. Close the front cover.

For MFC series printers do the following;

1. Open door
2. Press Clear/Back key
3. Press *00
4. Press OK

Do not choose anything for drum replacement. when drum replacement menu comes up, just press the * and then 00, then just press OK.

The drum unit uses a page counter on the printer that MUST be MANUALLY reset each time a new drum unit is installed.  If the drum light is still on after replacing the drum unit this means that the drum life has not be reset on the printer.  The procedure for resetting the drum life varies depending on the Brother printer so refer to the User’s Guide of the specific printer model.  These can be accessed on Brother’s website.  On the HL-5340D printer, you will want to press and hold the GO button for about 4 seconds until all the LEDs on the printer light up.  Once all 4 LEDs are lit, release the GO button.

 

Not Fitting

 

The toner cartridge and drum unit are two separate pieces that install into each other.  When replacing the toner cartridge you MUST remove the old drum unit from the old toner cartridge and re-use it with the new toner cartridge.  Install the new toner cartridge into the old drum unit before installing them into the printer.  If the customer is saying the toner is too small then they probably are attempting to install the toner cartridge on its own without the drum unit.  Make sure they install the toner into the drum first then install into the printer.

To remove and install the TN650 toner cartridge and DR620 drum unit in a Brother HL-5340D printer do the following;

Note:  Other Brother printers that use this toner and drum unit will be a similar procedure.  If you want specific instructions for a particular Brother printer model please review the User’s Guide for that particular printer.  The User’s Guides are available for free on Brother’s website.

–          Press the front cover release button and then open the front cover.

 

–          Take out the drum unit and toner cartridge assembly.

 

–          Separate the toner cartridge from the drum unit.  Press the blue lock lever to release the toner from the drum unit.  If the toner cartridge currently installed has the soft rubber pads then simply pull the toner out from the drum unit.

–          Insert the drum unit and toner cartridge assembly back into the printer.  Make it is fully seated.

 

–          If just a new toner was installed no further steps are required.  If a new drum was installed then the drum life MUST be reset.  On the HL-5340D printer, you will want to press and hold the GO button for about 4 seconds until all the LEDs on the printer light up.  Once all 4 LEDs are lit, release the GO button.

 

Print Quality Issues

 

On the TN650 toner cartridge there is a plastic protective cover on the front of the cartridge which must be removed prior to installation.  On the DR620 drum unit there is a black piece of paper held on by tape that covers the OPC drum which must be removed.

 

On the TN650 toner cartridge, check the rubber roller for damage or debris.  Do NOT touch the rubber roller or use moisture of any kind around the toner cartridge.

 

On the DR620 drum unit with the toner cartridge removed, check the OPC drum for damage or debris.  Do NOT touch the OPC drum or use moisture of any kind around the drum.

 

On the DR620 drum unit try cleaning the primary corona wire.  On the front of the drum unit there is a tab.  Gently slide this tab left to right a few times to clean the primary corona wire.  Make sure to return the tab back to its home position.  If it is not returned to the home position then a verticle stripe will appear on printed pages.

.

Try gently rocking the toner cartridge from side to side a few times to evenly distribute the toner powder 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 drum unit is a maintenance item and will need to be replaced after a period of usage.  Ghosting, streaking, and lines are generally a drum related issue.

 

 

Grinding

 

Remove and re-install the toner cartridge.  Make sure the toner cartridge is fully seated inside the drum unit.  Be sure that the toner and drum assembly are fully inserted into the printer.  Excess toner or debris on the gears of the drum unit may also cause grinding, a can of compressed air can be used to clean the gears.
