Download Epson Resetter

There are several chip vendors working on strategies now. My understanding is that a circuit board will be introduced quickly but it will violate the warranty of the printer to install it and turn off the chip recognition. That is being done now on certain of the high end Epson label printers as well as the lower cost label printers that were employing new chip technologies.
For a refillable cart, it will take time for a chip to be designed. Maybe a year or more for these - unless there is a breakthrough that can get around the inability to write back to the chip a date and other critical informations.
new head = new head factory
go read Epson annual report
the new head factory they invested in is not making this head
it makes heads for $100,000 business inkjet printers - with some really cool features such as missing jet detection / replacement
the new head increased the size of the chamber between nozzles which stopped the channels from frying
that would have fixed this issue - but the cost of retooling a new head is 100s of millions and our market is not producing the returns that business inkjet is.
business inkjet is the new epson.
Dana is out today and maybe online later this evening to help you. I will try my best with this issue. These errors are commonly addressed in our FAQs on large format carts. What is unusual is that you have been using these carts and suddenly all four on one side of your printer are not working. The resetter is behaving as expected, but the chips are not being read. Are you 100% absolutely sure that the carts are in the correct positions? Some our refillable carts can fit in any position. The chips of course are position dependent. Please double check that.
If so, you can take the chip off this Epson cart and adhere it to your refillable cart and start printing today. It pries off easily and you attach it FIRMLY with double sided sticky tape. We have a doc on how to do that on this website.
But, we also noticed that you placed a Web order with us for a set of carts for the 4880 printer and you are indicating that your printer model is a 4800. It is strange that the carts worked at all in your printer. But, now that they have been encoded by the Epson driver - resetting is probably scrambling them. I believe that you should buy a new set of chips and completely replace all of the chips. If you intended to order carts for your 4800 you certainly did not.
This is the first time we have heard of anyone being able to use 4880 carts in a 4800 printer. But, I think that your issue is reprogramming of a confused chip at this point. I think that as you progress to refilling the others it will happen again unless you replace the chips with the 4800 chips you actually require.
Is there some chance at this point that you actually do have a 4880 printer? Or are you certain that you have a 4800 printer. I will send you a copy of your original web order to confirm you purchased a 4880 set of carts.
While the 4880 carts can fit into a 4800 printer, the chips are totally different. I do not understand why initially the 4800 printer accepted the 4880 chips. But, eventually the printer begins encoding the chips with remaining ink levels and other information. And the fields and strings which it uses are different for the 4880 printer than they are for the 4800. When you went to reset the chips, they were obviously scrambled from having gone through an identity crisis.
The chips come pre-programmed and read full, etc. and have many different fields containing bits and strings, etc that are required for the printer to operate initially. During printing, the printer itself begins to record data onto the chips. Mostly this data is the amount of ink level remaining that it has computed by counting the drops printed and the amount of ink consumed during cleaning operations.
If you attached the Epson chips to the refill carts, reset the chips to read full, and they were all working well- why did you then remove them and attach the replacement chips we sent, instead of just printing with the Epson chips attached and keeping the ones we sent as spares?
NOTE: This resetter can only be used on a maintenance tank that is not already reading full. In addition, you will need a second maintenance tank, this one can be empty or full.
Remove the Epson T0801, T0802, T0803, T0804, T0805, T0806 cartridges from your printer and place them on the table as shown in picture 1, with the black label facing you. Pierce the black plastic film in the position indicated in pictures 1 and 2 using a pin or the needle of a syringe.
Fill a small bowl with ink. The ink outlet of the cartridge has to face upwards (picture 3). Place the syringe (without needle) over the ink outlet (picture 4) and pull the piston up. This creates a vacuum inside the cartridge, which is balanced by the ink from the bowl being sucked into the cartridge. Make sure that the filler opening you created is always submerged in ink. Otherwise, the cartridge will suck in air instead of ink. When the syringe draws only ink, the cartridge is full. Close the filler opening with a drop of hot glue (picture 5). Now you have to reset the Epson T0801, T0802, T0803, T0804, T0805, T0806 cartridge with a chip resetter.
As these Epson cartridges are equipped with a chip that monitors the filling level, you have to reset them after refilling.
Attention: When the chip of the Epson cartridge signals that the cartridge is "empty", it can no longer be reset. More information is provided under "Particularities of Epson T0711 - T0714, T0801 - T0806 cartridges".
Position the contacts of the cartridge chip in the chip resetter as shown in picture 6. The four contacts of the chip have to be in line with the contact pins of the resetter. The lamp of the chip resetter blinks red once and then glows green (pictures 7 and 8).
The cartridge is now reset and can be reinserted into the printer.
Refilling Epson T0711 - T0714, T0801 - T0806 cartridges poses some challenges.
Picture 9 shows the interior of the Epson T0711 - T0714, T0801 - T0806 cartridge body. The suction created by the syringe draws the ink through the filler opening and through all the chambers up to the ink outlet.
In order to be able to continue printing with the cartridge after refilling it and resetting the chip, the cartridge chip must not signal "empty". There is a sensor installed behind the wall with the chip which measures the filling level. Normally, this sensor is submerged in ink. When the cartridge is "empty", the sensor is surrounded by air (picture 10). Once the sensor gets in contact with air, this cannot be undone, i.e. the cartridge will always be recognised as "empty". Therefore, the cartridge must never be emptied completely.
An Epson cartridge has a memory chip that records the number of printed pages. The printer uses the page count estimating the ink level. Therefore, a refilled cartridge won't show a correct ink level because the chip remembers the old page-count When a cartridge prints too many pages, the printer will refuse to print, no matter how much ink is left.
When a printer shows low ink, we will take out the cartridge and add more ink. Then, we will put it on the resetter and press the cartridge down for a few seconds. A green LED light will indicate that the page number has been reset.
The resetter works on Epson original cartridges and most of the third party compatible cartridges. Because we can't test all the cartridges from the third party manufacturers, we only say the resetter works with all of the tested ones.
This Uni-Kit resetter will work on 9 chip cartridges, as shown on the diagram. The 4 top pins of the resetter must make contact with the 4 top terminals on the chip; the 3 bottom pins of the resetter must make contact with the 3 center terminals on the chip (you do not need to reset the 2 terminals on the chip that are to the far right or far left). Please be sure to refill the cartridge before reinstalling it into the printer.
TROUBLESHOOTING
1. The LED in the universal chip resetter does not flash/turn green. Answer: a). Make sure that the pins make good contact with the chip terminals b). If the chip is not made by the original cartridge manufacturer, the resetter may not recognize it.
2. Cartridges with 9 terminals on the chip could not be recognized* Answer: For cartridges with 9 terminals on the chips (T068, T069, T077 and T078 cartridges), the printer reads more than just the chip when determining the ink level status for the cartridge. The printer also reads ink level sensors INSIDE the cartridge, so the cartridge needs to be both properly resetted AND properly refilled in order for the printer to recognize it as full. During the refilling process, air could enter into the sensor areas. Make sure there is no air in the refill pockets (see image).
Please note that this resetter is designed to reset OEM (original brand) chips. It is not possible to test it or develop it to work on all types of 3rd party compatible chips, while we know that it does work on 3rd party compatible chips that we have tested, we cannot guarantee that it will work on all compatible chips, but it is guaranteed to work on the original brand chips.
