Mike Josiah of UniNet has instructions this month on “Remanufacturing the Samsung ML-3712 Toner Cartridge.” He reports that while these cartridges look similar to other Samsung cartridges, there is a dramatic change, in that there are no screws in the outside of the cartridge at all; instead, there are plastic rivets that need to be cut off, holes drilled and screws installed to hold them back on. Have no fear; Josiah provides complete instructions in this article.
Learn how to remanufacture HP laserJet Enterprise M4555 MFP toner cartridges in this month's Technical Step-by-Step. These are nice cartridges to do, in that there are no plastic rivets to cut or drill, all the screws are the same size, and no glue-type seals are used anywhere inside.

These cartridges and the printers take a page from the old HP color LaserJet 4500 machines. The printer is a carousel type with a central drum unit. The toner cartridges just have the toner and developer rollers. There are no drum or waste sections.

The Brother HL 3040 printer engine is based on a new 17 ppm black and color, 2,400 x 600 dpi color LED engine. The machines come standard with 32MB of memory, expandable to 512MB, and all run off a 300 MHz processor. LED printers use an LED array instead of a laser/scanner unit to print. The toner cartridges do not have a reset chip on them but do have a reset gear that must be positioned properly for the machine to accept it as a new cartridge. The starter cartridges that initially came with new printers do not come with a reset gear. A new gear can be added and the starter cartridge made into a full TN210 cartridge.

While these cartridges look similar to other Samsung cartridges, there is a dramatic change in that there are no screws in the outside of the cartridge at all. There are plastic rivets that need to be cut off, holes drilled, and screws installed to hold them back on. It’s not a hard process and it’s covered completely in the instructions.
