REMANUFACTURING THE BROTHER HL 2030 TONER CARTRIDGES • TN-350 (TN-2000 EUROPE) Released in January 2005, the Brother HL-2030 printer engine is based on a new 20ppm, 1200 DPI laser engine. While it is similar to previous Brother engines, there are differences. Beside physically looking different, the toner is also new. The first section of this article covers the theory behind these cartridges. If you are already familiar with the pitfalls of the HL-1240 cartridges, there is nothing new in the theory here.
WHAT DOES THIS ALL MEAN? 1. Make sure that your cartridge technicians thoroughly clean out the supply chamber of the toner cartridge. 2. In the event that they forget, and you have a shading cartridge. The toner must be completely cleaned out again (do not use the toner over!!), and NEW fresh toner MUST be installed. 3. The drum unit has to be taken apart and cleaned out with emphasis on the cleaning brush area. This is a very simple process but very necessary once contaminated.
UNINET IMAGING INC. • BROTHER HL 2030/TN 350 CARTRIDGE REMANUFACTURING INSTRUCTIONS 1. Vacuum the exterior of the cartridge. 2. Remove the fill plug from the toner cartridge. Dump the remaining toner and vacuum/blow out the cartridge. Make sure that the gear area is clean. Leaving any toner in the teeth of the gears may cause a tooth to be damaged and cause a clicking noise. We have found it best to use compressed air to clean them out, but to also keep one hand over the gears to protect them. NOTES 3.

On the GEAR SIDE, remove the three screws and cover plate. 6. A white flag gear will fall off as the plate is removed. This flag resets the printer when the cartridge is installed. New starter cartridges do not have this flag gear. Until they are available, the starter cartridges cannot be remanufactured. w w w. u n i n e t i m a g i n g .

Remove the developer roller. 10. Vacuum the doctor blade and foam feed roller clean. We do not recommend that the doctor blade be removed and the developer roller felt seals will be disturbed. Once a new blade is available, great care will have to be taken not to tear the seals, causing a leak.

Clean the gears, making sure that they have no toner on them. This is a good time to also check the gear shafts to make sure there is enough grease. If the shafts appear dry, or the grease is contaminated with toner, clean the shaft and inside of the gear. Replace the grease with white lithium grease. 13.

Make sure the clear plastic plug for the optical sensor is locked in the proper position. 16. Install the developer roller gear, c-ring, and black axle.

COMMON TONER CARTRIDGE PROBLEMS As some problems can be caused by both the toner cartridge as well as the drum cartridge, we have listed both here. BACK-GROUNDING: Toner cartridge and Drum cartridge; By far the most common problem with these cartridges, there are three major common causes. 1. The first is contaminated toner. If the old toner in the toner cartridge was not fully cleaned out, a shaded background will result usually over the entire page.
