ReChargX™ RX237 Instructions

For use in the Brother TN670 and TN4100 toner cartridges

The Brother TN670 and TN4100 are the toner

cartridges most frequently found in the Brother

HL-6050, HL-6050DN, HL-6050DW and all other

machines using the same underlying “engine”

(gure 1).

These toner cartridges are quite easy to rell

using our ReChargX™ RX237 Premium Print

Toner Rell Kit.

Within these ReChargX™ RX237 Premium

Print Toner Rell Kit instructions, we will be

adding new toner and resetting the ag gear.

Step 1: Orient the Drum Unit

When you remove the toner cartridge from your

printer it will be resting in the drum unit.

Orient the drum unit on your work surface so

the handle of the toner cartridge is facing toward

your chest (gure 1).

Step 2: Remove the Toner Cartridge

Press and hold down on the blue tab located on

the right side of the drum unit, shown by the

white arrow in gure 1. Lift the cartridge up and

out of the drum unit, shown in gure 2.

Place the drum unit off to the side for the time

being; it will be used again later.

Step 3: Orient the Toner Cartridge

Orient the cartridge on your work surface so the

developer roller of the cartridge is away from

your chest and the handle is toward your chest

(gure 3).

Step 4: Cover the Developer Roller

This step is recommended since the developer

roller is completely exposed and easy to damage

by scratching or contaminating with ngerprints,

affecting it’s ability to create a quality image.

Using a normal sheet of printer paper, tape the

paper to the top side of the cartridge, shown in

gure 4a.

Fold the paper over the leading edge of the

cartridge and tape the other edge of the sheet

of paper to the opposite side of the toner

cartridge (gure 4b).

Step 5: Orient the Toner Cartridge

Orient the cartridge on your work surface so

the end of the cartridge with the label and toner

hopper plug is facing upward, shown in gure 5.

The toner hopper plug will be located underneath

the label of the cartridge.

Step 6: Remove the Cartridge Label

Using the edge of a at-blade screwdriver, slice

through the label on the side (gure 6).

cartridge

cartridge

Step 7: Remove the Toner Hopper Plug

Wedge the edge of a at-blade screwdriver

down between the lip of the cartridge and the

toner hopper plug then pry the plug up and

out, gure 7.

Do not worry about damaging the plug, we include

a replacement plug with the ReChargX™ RX237

Toner Rell Kit. However, be careful not to damage

the toner cartridge itself.

Step 8: Empty the Toner Hopper

You must remove any toner that is still in the

toner hopper before relling.

NOTE: This step does not need to be repeated

the next time you rell.

NOTE: This toner cannot be used again, the

new toner being added cannot mix with the

OEM toner. Failing to remove the toner before

relling will result in signicant hazing on some

or all of the printed page that will not go away

with further printing.

Open the plastic bag, included in the ReChargX™

RX237 Toner Rell Kit, and lower the toner cartridge

so the toner hopper hole is in the bag.

Carefully pour out as much of the remaining

toner as possible (gure 8).

Shaking the toner cartridge up-and-down is

not recommended as it normally creates an

unnecessary toner mess.

If the toner stops owing, stand the cartridge

up and then lower the toner hopper hole into

the bag (gently tapping along the side of the

cartridge helps to keep the toner owing).

With the majority of the toner removed, seal

the bag and toss it in the garbage.

Figure 8: Empty the residual OEM toner

Step 9: Add ReChargX™ RX237 Premium

Print Toner to the Toner Hopper

Now we will ll the toner hopper with the

ReChargX™ RX237 Premium Print toner.

To ensure the toner ows freely from the bottle

during lling, make certain the cap is screwed

tightly on the bottle, then gently rock/shake

the bottle to free up the toner that may have

settled during shipping.

Next, remove the original cap from the bottle

and replace it with the plastic dispenser spout

from the ReChargX™ RX237 Toner Rell Kit.

To make the adding of the toner to the toner

hopper as easy and dust-free as possible, tilt

the end of the cartridge with the hole in it up

at a 45 degree angle and slowly angle the

dispenser spout on the bottle of toner to meet

up with the hole, as shown in gure 9.

Tilting the bottle up a little more will start the

toner owing into the toner hopper.

NOTE: If at any point the toner stops owing,

simply stand the bottle upright to loosen the

toner and start the pouring process over again

(resist temptation to squeeze the bottle as it

will make a spill or mess more likely).

Fill the hopper until it appears to be full or until

it appears toner no longer ows easily into the

hopper (any toner left in the bottle can easily

be added in the future after you have done a

considerable amount of printing).

Figure 9: Fill the toner hopper

Step 10: Clean the Area Around the Toner

Hopper Hole Before Sealing

Unfold the yellow/orange “toner grabber” cloth

from the ReChargX™ RX237 Premium Print Toner

Rell Kit and stretch it along both dimensions (it

will stretch considerably in one dimension and

not the other). Stretching the yellow/orange

toner grabber cloth activates the toner retaining

substance that is embedded within the cloth.

You will be using this cloth to clean the outside of

the toner hopper hole to ensure the plug will be

applied rmly and securely to the cartridge, as

shown in gure 10.

NOTE: Only use the toner grabber cloth on the

exterior of the toner cartridge around the toner

hopper hole area. Do not use the cloth to clean

any of the internal components or the cartridge

developer roller.

Step 11: Plug the Toner Hopper Hole

Place the plug over the hopper hole, press rmly

around the entire perimeter of the plug to make

certain the plug sits securely inside the toner

hopper hole (gure 11).

NOTE: Do not press hard enough for the plug

to go through the hole and into the cartridge.

Step 12: Locate and Remove the Screws

Holding the Cartridge End-Cap

in Place

Now we will proceed to the last step in this rell

process. Resetting the ag gear.

With the cartridge in its current orientation you

will notice three screws that hold the end cap in

place, shown by the white arrows in gure 12a.

Using a phillips-head screwdriver remove the

screws holding the cartridge end-cap in place

(gure 12b) and set the cartridge end-cap aside

for future use.

Step 13: Locate the Flag Gear

The ag gear is the large black gear in the cen-

ter of the toner cartridge, shown by the white

arrow in gure 13.

NOTE: If your toner cartridge does not have

a ag gear, add the new gear from the RX237

Toner Rell Kit as shown in step 14.

Step 14: Reset the Flag Gear

Reset the ag gear by lifting up on it slightly

and rotating it counter clockwise until the tab

moves from the three o’clock position to the

twelve o’clock position, shown in gures 14a

and 14b.

Step 15: Reinstall the Cartridge End-Cap

Place the cartridge end-cap back onto the

cartridge the same orientation as when you

rst removed it. Then reinsert the screws, set

aside earlier, back into the same locations and

secure the gear casing onto the toner cartridge,

gure 15.

Step 16: Remove the Piece of Paper

With the cartridge relled and the ag gear

reset, remove the paper from both sides of the

developer roller, as shown in gure 16.

This piece of paper can now be discarded.

Step 17: Reinstall the Toner Cartridge

Return the newly relled toner cartridge to the

drum unit (gure 17) and insert it into your

printer.

ReChargX™ RX237 Addendum

Special instructions to resolve symptoms of vertical white

streaks/light print through text or graphics

Paper particles and other debris tend to

accumulate on the “doctor blade” in this

toner cartridge. ONLY if your cartridge

is exhibiting vertical white streaks (fairly

distinct and thin as opposed to large areas

missing toner which are simply indicative of

a cartridge running out of toner), perform

the following steps.

(CRITICAL NOTE: DO NOT perform these

steps unless your cartridge is exhibiting the

distinct white vertical lines mentioned above.

There is no reason to perform these steps,

at all, if you are not seeing those distinct

vertical white lines. In fact, there are many

reasons NOT to perform these steps except

in those cases where the white vertical lines

are visible.)

If you complete the following steps and are

still seeing the vertical white streaks it may

be time to replace the toner cartridge.

Step 1: Orient the Toner Cartridge

Orient the toner cartridge with the top of the

toner cartridge facing away from your chest

and developer roller facing up (gure 2), the

doctor blade is the shiny metal strip along

the front edge of the cartridge, just above

the developer roller.

affected by paper particles or other debris

and the roller facing up

Step 2: Locate the Screws Holding the

Doctor Blade in Place

The doctor blade is held in place with two

small phillips head screws, one at each end

of the blade as shown by the arrow in gures

3a and 3b.

Step 3: Remove the Screw on the Left

Side of the Doctor Blade

Remove the screw on the left side of the

doctor blade, rst (gure 4).

place on the right side of the cartridge

Figure 4: Remove the small screw on the left side

TonerRellKits.com RechargX™ RX237 v1

Step 4: Remove the Screw on the Right

Side of the Doctor Blade

Next, remove the screw from the right side

of the doctor blade (gure 5).

Step 5: Remove the Doctor Blade

Gently pry up on the doctor blade with a

small at blade screwdriver on each end of

the blade to free it from the hopper (gures

6a and 6b).

NOTE: Be careful not to bend or twist the

doctor blade.

Step 6: Clean the Doctor Blade

With the doctor blade removed from the hopper,

use a cotton swab (moistened with isopropyl

alcohol, if available, if not a dry cotton swab will

work ne. DO NOT USE WATER) to clean the

length of the dark portion of the doctor blade

front and back (gure 7).

Here is a close-up of the doctor blade assembly

and the dark portion you are to clean (gure 8).

Pay particular attention to any toner that is

stuck to the doctor blade. Do not use any

sharp objects to clean the doctor blade or it

may be damaged.

NOTE: Be careful not to bend or twist the

doctor blade.

Step 7: Replace the Doctor Blade

When you have nished cleaning the doctor

blade insert it behind the rubber developer

roller and lower it back down into place in

its original orientation (gure 9a).

Secure the doctor blade in place with the

small phillips head screws on both sides of

the toner cartridge (gure 9b).
