Ausjet Cartridge Selector:
We have spent a lot of time recently updating our cartridge selector on our website. From our cartridge selector you can find the following information :
Which cartridges are used in selected printers
Which inks, instructions, clips and seals etc we have for the cartridge you are searching for.
Photos and descriptions of products.
Its a good tool for you to easily find information about our products. I hope you make good use of it.
Procolor Pgi-520\Cli-521 Resetter available Soon:
We have just had final confirmation that the development for this Procolor resetter is now complete. This is GREAT NEWS as this means that finally a reset solution is available for your customers that use these printer models. You can now refill and reset the procolor Pgi-520\Cli-521 cartridges to fully functional with full ink levels.
Epson 73N firmware upgrade:
We have heard from various sources that Epson has released a new update with the 73n which as usual will cause a bit of havoc with compatible Epsons. Fortunately at this stage our Procolor chip seems to be handling most firmware issues quite well.
Resetting Procolor Pgi-5\Cli-8 with our Mean Green Resetter:
As well as resetting the OEM pgi-5\cli-8 range of cartridges the mean green resetter will also reset the Procolor range. A recent update to the chip on these cartridges has had the effect of a slight change to the resetter procedure. Previously when you reset the procolor cartridges the red light would stay on at the end of the reset, now the only indication of the chip been reset is that the chip light flashes once. But don't worry, one flash indicates that the chip is reset.
From ink injection to the nozzle plate (Thermal foam based cartridges) - An Overlook On How It All Works
Ink injection:
No matter what filling equipment you use, you should aim to accomplish at least the same fill volume as the OEM cartridge. There are a number of factors that can contribute to this not occuring.
1) Speed of filling - you may be filling too quickly resulting in frothing of the ink.
2) Condition of foam - its current state - how hydrophilic the foam current is. Cleaning the foam and allowing to dry is often used to bring the foam back to a hydrophylic state.
3) Air trapped in the foam - Removal of air from the foam(vacuum filling) greatly increases the chance of filling to the correct ink volume.
Inkjet Foam(sponge):
A high percentage of all OEM cartridges on the market are foam based. In our industry many people refer to the foam as a sponge but this technically isn't correct. Over the last few years the OEM's have been (generally) producing higher density foams. If you look at different types of inkjet foams you will see that generally speaking in older foams it is quite easy to see the cell structure, whereas in more recent foams the density has increased and its almost impossible to see the cell.
The foam is also responsible for creating the backpressure (commonly referred to as negative pressure). The backpressure stops the ink from leaking. It is critical to have the right ink matched to the right foam as well. Ink has to have the right viscosity to have the correct flow rate through the foam. The correct viscosity ensures that the backpressure is not too high. Over a period of time too much backpressure will result in the ink actually been withdrawn back from the printhead into the foam.
Gauze Filter :
Before the ink passes through to the printhead area, it is important that the filter stops potentially nozzle clogging particles. The nozzle sizes these days are approx between 10-20 micron in diameter. As you can imagine, without the filter there would be lots of problems. It is also important that the filter does not have dried ink attached to it as this will restrict the flow to the prechamber which may cause flow problems during printing.
Prechamber and channels:
The prechamber is the area where the ink is pooled. Channels running from the prechamber connect with all the nozzle chambers. It is very important that the correct amount of ink is in the prechamber, as again no ink or low ink is this area may cause flow problems and ink starvation to the printhead.
This is the common reason why you can't just fill a cartridge and expect it to work. You really need to prime the printhead which pulls ink from the foam into the prechamber and into the nozzles. The same result can also be achieved by centrifugal force - a manual priming function built into a centrifuge is a big asset.
Heaters/Resistors :
For every nozzle inside the printhead there is also a heater/resistor attached to it. The heater/resistor is what causes the ink to 'jet' onto the paper. A small voltage is applied to the heater to activate that nozzle, the resistor then heats up causing a vapour bubble to be created. The expansion of the vapour bubble takes up space in the chamber displacing the ink and this forces the ink to jet out. All thermal printhead designs rely on the vapour bubble to fire the ink out of the printhead. They have varied designs with Canon calling their technology bubblejet and HP calling their's roofshooter (because it has the ability to jet upside down).
In many of the new printheads there are as many as 3000 nozzles, which means 3000 heaters/resistors in that small area. Simply amazing technology if you think about the size and the speed it all works at.
There is a number of factors which result in the failure of the heater/nozzle :
1) Age - like many electronic items - don't expect them to last forever.
2) Printing without ink firing onto the page can cause a problem - this means that ink is not filling up the nozzle chamber. This results in the heater/resistors firing but with no ink in the chamber to move the heat away will result in this area becoming hotter than expected. Nowadays printheads seem to be more tolerant to this problem than they were in earlier days, but it is quite possible that this could be weakening the resistors which could lead to an earlier failure than expected.
3) Constant creation and collapse of the vapour bubble will eventually result in the walls of the nozzle chamber breaking and damaging the heater. More and more technological advances in this area have resulted in various patented layers of materials placed between the resistor and the chamber to prevent this from happening. Recent advances have allowed longer life thermal printheads from manufacturers such as Canon, HP and Lexmark.
4) Kogation - from the japanese word 'koga' meaning biscuit. Refers to the build up that can occur on resistors over time. Too much build up may result in a weakened vapour bubble which does not produce an accurate jet or eventual failure. A good cleaning system that is not linear and can clean around corners like an ultrasonic cleaner is the best to remove kogation. It has recently been discovered than some inkjet inks may results in more kogation than others, it's another reason why you should only choose a quality ink.
With the good mark one gets from refilling inkjet cartridges, I personally cannot understand why anyone would not choose to use the best ink available to them. There are many factors that cannot be seen inside the printhead that may result in earlier failure due to not using a high quality ink which has premium components which prevent these issues. The difference in costs per refill between a premium and bodgy ink are cents. Why risk losing a customer or reducing the number of refills you can do because of a few cents per refill?
You can test the resistors by purchasing circuit testers. They will test each resistor and confirm that they are all within the correct working resistance range. This is the only way to know for sure the state of the resistors.
If a resistor has failed this means
1 Failed Resistor = 1 Failed Nozzle
A failed resistor may also cause a break in a series of resistors and could result in :
1 Failed Resistor = Many Failed Nozzles
Nozzle Plate :
The nozzle plate is the part of the printhead we see. Nozzle blockage will occur here. It's a very simple case of the water evaporating out of the ink at the nozzle position. No matter what environment you are in, evaporation will happen (even in an air conditioned office) .Depending on the formulation, water makes up 50%-70% of the ink and with the removal of water the viscosity of the ink becomes much thicker and eventually dries which causes the blockage. A longer period exposed to the environment will also result in drying of the ink in the channels, prechamber and on the filter. This will of course require more cleaning activity to get the cartridge working correctly.
I hope this information has been helpful to you.

Technical Bulletin : Remax Asia Pacific
Remax Asia Pacific 2009
14th – 16th October, Zhuhai China
Zhuhai is often referred to as the world centre for printer consumables. The Pearl river delta where Zhuhai is located has over 600 factories specialising in printer consumables. This makes it a perfect location to hold an industry trade show. Not only can you visit the the show but in many cases you can also organise a tour of a factory to view/verify for yourself the quality of the goods and the quality procedures that are employed.
Zhuhai is conveniently located only about an hour away (by ferry) from Hong Kong and also borders Macau the "Chinese Las Vegas". The Venetian Hotel is three times larger than any hotel in Las Vegas! Zhuhai is a modern Chinese seaside city and is often referred to as a 'romantic city' and attracts its fair share of tourists each year.
In 2009 the number of exhibitors had grown by 56% to a total of more than 292 exhibitors, an increase of 102 exhibitors. The show area was also increased by over 100% compared to 2008. On the first day 3700 visitors attended with a total of the show of 7238 visitors from 75 countries and regions. General opinion amongst the exhibitors was that this show was busier than the previous remax show but didn't have as many visitors as the Rechina show which was held in Shanghai in November last year. However we feel it is better organised. The questionaire survey for exhibitors showed that 90.3% of them were satisfied with the show, 80% received more than 100 clients with over 50% of the clients received being new clients.
The goal of our visit to the show was to:
-
Look for new innovative products to keep our customers at the forefront of the industry.
-
Talk to our manufacturers about new products and discuss ways to improve their products for our needs and strengthen the business relationship.
-
Find out the latest information on the development of resetters for a wide range of cartridges.
-
Network with remanufacturers from around the world and discuss what problems they are having and any solutions they may have found.
-
Gather industry information that will assist us and our customers in the future.
-
Visit factories to better understand how cartridges are manufactured and remanufactured in this part of the world.
-
Learn more about chip technologies and how this will effect us in the future if the current trend of highly encrypted chips continues.
-
Look for a wide range of new products to increase our product range.
-
Find new contacts
-
Increase knowledge and expertise

Shuttle Bus – Off We Go I Think
We had organised to stay in a hotel that had a free shuttle bus courtesy of Printrite) to the remax show. The hotel was approx 60 minutes from the show by taxi and 90 minutes by the shuttle bus. It was obvious from the very first bus that the transport organisers had underestimated the demand for the free shuttle service. The first bus arrived and was very quickly filled up.We caught the 2nd bus not long after and when we reached the next stop the bus was quickly filled up. Obviousley those waiting at other hotels to be picked up which were further down the line were in a bit of a tizz as it took longer for their transport to arrive.
The Adventure Begins
We arrived at the show and previous experience had told us to be brave. We were soon to be attacked by booth attendants..... one rule you must never forget 'Don't stop moving' if you stop you are surrounded. To keep going you must take a brochure and hand over a business card, its a weird ritual but when in an environment like the remax show it's important to remember what to do.
The first day we decided to circle the Remax show attending all the booths on the outside. This way we were always close to an exit, an experienced bushman will tell you to know your exits. We weren't taking any chances, I for one was hoping to be able to return back to the land of the Aussie after we had learned the secrets of the cartridge industry.
I thought an international incident might occur, but luckily we found a thunderbox that didn't require squatting, nothing could hold us back now. Over the next few days we explored the remax show looking for that 'bright yellow' flashing product. The product that all cartridge sellers in the world would need, we thought we found it but it turned out to be some amber ale at one of the booths. They say many of the worlds best designs can be found at the end of a drink and funny enough we did discover a very good product at this stand.
Beer, Premier league(Soccer) and a LED Flashing smiley face
On the Thursday night we attended the Remax Beer Night located at where else but Bar Street. The Beer night was all you can drink for one low price deal. With premier league football on the large screen tv and us all wearing our LED flashing badges the night was sure to be a good one. I believe functions such as this are a great opportunity to network with industry colleagues from around the world. At our table I was seated next to the head of ICCRA (Indian Cartridge Remanufacturing and Recycling Assocation) and it was interesting talking to him about the industry in India. Surprisingly still able to put one foot in front of the other we walked away and visited the next few bars. Had a couple of games of dice poker which is very popular in china and headed back.
Update on Resetters (OEM) – No solutions yet
With OEM manufacturers using more advanced levels of encryption on cartridge chips, this has directly resulted in a longer period of time to crack the chips. Everybody it seems is looking for a resetter for the Pgi-520\Cli-521 cartridges. Since February this year we have been promised a resetter, Every time we enquire about the availability it is always two weeks away. In China I was determined to find out what the latest news is regarding this resetter.
The latest news is that there is a resetter that can successfully reset these cartridges, but for reasons they can't explain a percentage of these cartridges will not indicate the full ink levels in the printer. This problem is not printer specific and doesn't happen with all cartridges. So I think there is still work to be done, but it does sound promising.
Update on Resetters (Procolor) - Solutions Available
If no chip resetting solution is available for the OEM cartridge, we really try to bring you solutions that allow our Procolor cartridges to be refilled and reset. As you are probably aware we introduced a resetter for the Procolor 73N and 81N cartridges which allows these cartridges to be refilled and reset. I believe this is a win-win solution as the Procolor 73N and 81n cartridges are easier to fill than the OEM and also have proven to be very reliable over a number of fills.
We have also good news for the Procolor Pgi-520\Cli-521 cartridges, a resetter will be available for these cartridges in about a months time. This is a guaranteed solution as the resetter has fully passed all required testing. The electronic part of the resetter is ready, we are now just waiting for the plastic shell to be made.
Chip manufacturer Factory Tour
I was lucky enough to visit a chip manufacturing plant in Zhuhai. It was very interesting how the chips are put together, robotic machines placed the layers of parts on the chips at amazing speeds. Software built into the machine would then take a photo of each chip and then study the photo to confirm that the parts are placed in the right position. The chip was then put into to an oven to allow the parts to fix together, the chips are then electronically tested to ensure that all connections are correct. Software data is then programmed into the chip. The chips were then tested again to confirm the data on the chip is correct.
Exhibitors
With over 290 exhibitors it took us three days to fully get around to everybody we needed to see. The breakdown of exhibitors at the show was Laser consumables and components 62%, inkjet consumables and components 19% and machinery 4% and 15% others. Products at the exhibition included many brands of compatible and remanufactured toner and inkjet cartridges, inkjet ink manufacturers, ribbons, inkjet papers, chip manufacturers, CISS manufacturers, thermal transfer rolls, toner and inkjet machines, toner parts, chip resetters etc.
Over the course of the three days we sourced many potential new products, many of these products we still have to do considerable testing on before we progress further. We also took the opportunity to discuss with our existing manufacturers, covering such topics as future products, more marketable packaging , more promotional material for customers, various transportation issues and suggested improvements to products. It's much easier to discuss these topics face to face and much more productive.
