Remanufacturing the Lexmark X560 Toner Cartridges

By Mike Josiah and the Technical Staff at Uninet Imaging

Mike Josiah Mike Josiah is the Technical Director at UniNet East Coast office, a global distributor of toner, Smartchips, OPC drums, and other toner remanufacturing components. Mr. Josiah is an industry veteran since 1987, and a member of ASTM committee F.05, the STMC Technician Certification committee, as well as an STMC trainer. He and his support team at UniNet contribute with technical articles to industry trade magazines, and conduct seminars at association meetings and tradeshows worldwide.

The Lexmark X560 Engine is a multi function 31 ppm Black and 20 ppm color engine that runs at 600 dpi (2400dpi image quality). The first page out is stated to be under 11 seconds and the printer runs off a 400 MHz processor. The memory comes standard at 384MB and is expandable to 1.4GB. These machines can print, scan, fax, copy and duplex.

The chips on these cartridges need to be replaced each cycle.

There are LY(Starter)cartridges and HY cartridges available. A LY cartridge cannot be made into a HY version as there are a set of gears in HY cartridges not present in Ly cartridge. HY cartridges use a second toner hopper based in the drum half of the cartridge. This hopper is present in the LY versions, but the necessary gears to move the toner are not.

These cartridges have a chip that must be replaced each cycle. In addition, they also have gears on the supply hopper(s) that must be set correctly for the cartridge to work.

The printers ship with a set of starter cartridges. Both the colors and the black are all rated for 4,000 pages.

Current Machines based on the X560 engine are: Lexmark X560n

Lexmark X560dn The cartridges used in these machines are as follows: 0X560A2KG Black LY Cartridge (4000 pages) 0X560A2CG Cyan LY Cartridge (4000 pages) 0X560A2MG Magenta LY Cartridge (4000 pages) 0X560A2YG Yellow LY Cartridge (4000 pages) 0X560H2CG Cyan HY Cartridge (10,000 pages) $412.65 List 0X560H2MG Magenta HY Cartridge (10,000 pages) $412.65 List 0X560H2YG Yellow HY Cartridge (10,000 pages) $412.65 List 0X560H2KG Black HY Cartridge (10,000 pages) $278.25 List As you can see, these are extremely profitable cartridges to do.

These cartridges use both toner and developer in the cartridges. This system is a little different so we are including the cartridge/printer theory here.

Figure #1 shows the basic layout of the cartridges as they relate to the printer and also list the steps used in the printing process. These steps are covered in more detail below.

In the first stage, the Primary Charge

!"#$%&"'#&()&!$*+

Figure 1 Roller places a uniform negative DC voltage on the OPC drum surface. The amount of the negative DC voltage placed on the drum is controlled by the printer’s intensity setting. The PCR cleaning roller removes any toner or paper dust from the PCR. See Figure 2

Figure 2 In the second stage, each color’s laser beam is fired onto a set of fixed mirrors

$)*+,#!+!-.! ,) !"#$ %!&'(& Remanufacturing the Lexmark X560 Toner Cartridges

and then to the rotating mirror (called the scanner). As the mirror rotates, the beams are reflected into a set of focusing lenses.

The beams then strike the drums surface, reducing the negative charge and leaving a latent electrostatic image on the drum.

The areas where the lasers did not strike the drum will retain the higher negative charge. See Figures 3 & 4

blade, which uses pressure to keep the amount of toner on the roller constant. See Figure 5

As the laser exposed areas of the OPC Drum approach the developer roller, the toner particles are attracted to the drum’s surface due to the opposite voltage potentials of the toner, and laser exposed areas of the OPC drum. See Figure 6

process again. The static charge on the back of the paper is decreased with static charge eliminator. This helps stabilize the paper feed, and also prevents toner flares (spots) under low temperature and low humidity conditions. See Figure 8

Figure 8 Figure 4 The third or developing stage is where the toner is developed on the drum by the developing section (or supply chamber), which contains the toner and developer particles. The toner is moved from the hoppers by a series of agitators into the developer section where the augers and magnetic roller are located. The toner is brought out to the drum by the magnetic roller. The toner is also held onto and attracted to the magnetic roller by a negative DC bias voltage. This voltage is controlled by the printer’s intensity setting and causes either more or less toner to be attracted by the developer roller. This in turn will either increase or decrease the print density. The amount of toner on the magnetic roller is controlled by the doctor

Figure 6 The fourth stage is the transfer stage.

This is where there are some large differences from monochrome printers and also from other color lasers. In the Primary transfer stage the transfer rollers which are located directly opposite each OPC drum, places a positive DC bias charge on the back of the Transfer Belt. Each toner cartridge has a separate transfer charge roller. As the paper moves through the machine, the image is transferred from the drum directly to the paper. This process is repeated for each color cartridge in the following order: Yellow, Magenta, Cyan, and Black. See Figure 7 The paper separates from the transfer belt as the belt turns back down to start the

!"#$%&"'#&()&!$*+

In the fifth stage, the image is then fused onto the paper by the fuser assembly.

The fuser Assembly is comprised of the upper heating assembly and lower pressure roller. The lower pressure roller presses the page up into the upper heating assembly which then melts the toner into the paper. This heating assembly is based on older technology. It uses a heat lamp and a pressure roller assembly and not the

ceramic heaters that many machines now use. See Figure 9 OPC Drum Cleaning: The drum is cleaned after the image is transferred to the paper by the wiper blade. This part is fairly standard; the wiper blade scrapes the toner off the drum, and the recovery blade guides it into the waste chamber. These machines also have an erase lamp to remove any residual charges from the drum and allow the wiper blade to clean better. See Figure 10

Remanufacturing the Dell 1230 Color Toner Cartridges

By Mike Josiah and the Technical Staff at Uninet Imaging The Dell 1230 printers are based on a 16ppm black and 4ppm color Samsung engine. It has a first page out in less than 14 seconds and a maximum resolution of 2400 x 600 dpi. The printer comes standard with 32MB of Ram, a USB 2.0 interface, and has a monthly duty cycle of 20,000 pages/month.

These machines have a very small footprint at 15.3” x 12.3” The machines are small and the toner cartridges are also small The Cartridges used in this series are as follows: 330-3012 Black 1,500 pages $57.99* 330-3015 Cyan 1,000 pages $51.99* 330-3014 Magenta 1,000 pages $51.99* 330-3013 Yellow 1,000 pages 451.99* 330-3017 Drum unit 24,000 pages black, 6,000 color
