MX-31NTBA, MX-31NTCA, MX-31NTMA, and MX-31NTYA

THESE TONER CARTRIDGES DO NOT HAVE THE OPC DRUM INTEGRATED.  THE DRUM UNIT IS A SEPARATE, REPLACEABLE, MAINTENANCE ITEM.

There are 4 colors in this cartridge series; Black, Magenta, Cyan, and Yellow.

These are compatible cartridges so there will be differences from the OEMs.  These differences will not affect function.

 

Not Recognizing

 

Verify you have the correct cartridges for your specific printer model.

 

There is a smart chip located on the end of each toner cartridge.  Check this chip for damage or debris.  A Q-tip or lint-free cloth can be used to gently clean the gold contacts.

 

Verify you have the correct color in the correct color slot.

 

To remove and install these toner cartridges into a Sharp MX-2600N printer do the following;

–          Open the front cover.

 

–          Raise the toner cartridge lever and gently pull the toner cartridge horizontally toward you.  When pulling out the toner cartridge, pull it out gently.  If the cartridge is pulled out abruptly, toner may spill out.

 

–          Hold the toner cartridge with both hands as shown and pull it out of the machine.

–          Insert the new toner cartridge horizontally.  Be sure you are inserting the correct color into the correct color slot.

–          Push the cartridge in until it locks securely in place.

–          Close the front cover.

Print Quality Issues

 

There’s a large protective cap on the end of the cartridge which must be removed prior to installation.

 

There’s a small plastic protective piece under the cap which must be removed prior to installation.

 

Shake the toner cartridge horizontally a few times to redistribute the toner powder inside the cartridge.

 

If black lines or colored lines appear the main charger that charges the drum can be manually cleaned by the user.  To clean the main charger do the following;

–          Open the front cover.

 

–          Press the waste toner box release button.

 

–          The waste toner box will fall forward.  Gently support the box with your hands as you let it fall forward as far as it will go.

 

–          Grasp the green knob to release the lock and gently remove the charger cleaner.

 

–          Clean the main charger by gently pushing the charger cleaner all the way in and gently pulling the charger cleaner out.

 

–          Insert the charger cleaner so that the cleaning location label (A) and the charger cleaner label (B) are together.

 

–          Repeat the previous two steps with each of the other main chargers.  There are a total of 4 places to be cleaned, one for each color.

 

–          Replace the charger cleaner in its original position.

 

–          Push the waste toner box into the machine.

 

–          Close the front cover.

 

Streaking, lines, ghost imaging, and repeating image defects are drum related issues.  If the above cleaning doesn’t help then their drum unit may need replacing which is separate from the toner cartridges.

 

Not Fitting

 

Verify you have the correct cartridges for your specific printer model.  Verify the plastic protective pieces have been removed.  Ensure that the correct color is going into the correct color slot.  Check inside the printer for any obstructions.  Check the cartridge itself for physical damage.
