Disassembly Instructions

Lexmark E-321/E323 Toner Cartridge

First released in April, 2003, the Lexmark E321/323 series of printers are based on a 20ppm 1200 dpi Lexmark engine. Lexmark is using the Prebate cartridges again, and these cartridges also use a non-resetable chip to prevent the Prebate car- tridges from being recycled. The Non-Prebate cartridges can be recycled without changing the chip. The E321/323 cartridges look like an E320, except for the Gray end caps. The chip on these cartridges is also completely different from the E320. The replacement chips for these cartridges have proven difficult to make, but with recent advances we are betting that as you read this, they will be available.

Lexmark currently has four cartridges available:

12A7300 STD (3K pages) Non-Prebate cartridge

12A7400 STD (3K Pages) Prebate Cartridge

12A7305 HY (6K Pages) Non-Prebate cartridge

12A7405 HY (6K Pages) Prebate cartridge

The HY Non-Prebate cartridges list for $196.00, where the HY Prebate cartridges list for $176.00. (Pricing as of Au- gust 2003). Lexmark is changing the way they describe these cartridges. Prebate cartridges are now “Use and Re- turn”, Non-Prebate cartridges are now “Standard”. Same thing different name. The cartridges themselves are fairly simple to do, and as you can see, have very nice margins!

Dell has released a printer based on this engine called the P1500. The chips in these cartridges are unique to Dell. Lexmark cartridges will not work in them.

In September 2003, Lexmark has just released the E220 printer. The E220 cartridges will work in the E321/323, but the E321/323 cartridges will not work in the E220. As this release just occurred literally as this was being written, No further information or test results are available.

These machines do not have a display panel; they have a series of lights that indicate the status. I will list some of the more common sequences & error codes at the end of this article. The machine also contains the PCR. When the lid is closed, the PCR drops down into the cartridge. Just like the Optra S series of machines.

On page 76 of the User Guide, Lexmark lists the replacement cartridges for this machine. Strangely, the Prebate car- tridge numbers made to stand out, non-Prebate part numbers very east to miss. In fact, unless you specifically look for them, you would never see them!

Another point in both the user guide and the service manual is that in the E321 machine only. If the Starter cartridge is installed, the toner low function will not work. No other explanation is given, but it is stated multiple times.

These cartridges are fairly simple in design, but can be rather tricky to do. As soon as you take an end cap off, the cartridge falls apart in your hands! Putting the cartridge back together is a challenge the first few times, there is defi- nitely a specific order that must be followed. We have gone into as much depth as possible in rebuilding the cartridge.
