Epson 604 instruction for alternative, refillable printer cartridges with autoreset chips

The alternative, refillable as well as reusable ink cartridges have quite a number of advantageous features. On the cartridge top of each of these cartridges is the filler opening for the matching printer ink. The opening is closed with a plug and is opened for filling refill ink that fits Epson 604 ink cartridges. Also on top there is another port - this one is for air venting the refillable cartridge.
At the bottom of the cartridge is the ink outlet opening with integrated closing valve. This opening is used to transfer the ink from the Fill In cartridge to the Epson printer. As delivered, there is a foil over this outlet opening - the foil is pierced when the filled cartridge is inserted into the printer, the valve in the outlet is opened and in this way the ink flow is established. The foil is not removed because it holds the rubber seal located in the ink outlet.

How to fill the refillable ink cartridges alternative to Epson 604 with the right amount of printer ink?
The ink is taken directly from the bottle with the printer ink compatible with Epson cartridge model 604. We have found that it is helpful to have some air in the syringe barrel at the beginning of the draw up. This makes it easier for you to read off the scale of the refill syringe how much ink is in the syringe.
Each of the refillable ink cartridges suitable for Epson 604 is filled with 10ml of the appropriate printer ink.
Open the filler opening, remove the plug for this purpose - keep it safe, it will be needed again for closing afterwards. Carefully insert the cannula attached to the refill syringe through the filling opening into the Fill In cartridge and carefully pour the refill ink into the ink tank. After filling the ink, close the filling opening again with the plug.

Installing the Fill In cartridge set in the Epson printer with Epson 604 ink cartridges
When installing the Fill In cartridges, remove the plug from the air vent. During printing, the vents on the Fill In cartridges must be open. Insert each of the fillable cartridges into the correct position in the print head carriage of the Epson printer. Make sure that the cartridges snap firmly into place - this ensures that the ink outlet and its valve open correctly and that there is contact between the ink chip on the cartridge and the contact pins in the printhead carriage.
 

If the complete set of Fill In cartridges is in the Epson printer, the cover above the printhead carriage can be closed. The printer display will indicate that non-genuine consumables are installed in the printer instead of genuine Epson 604 ink cartridges. This is correct.
The use of the alternative, refillable cartridges must be confirmed. To do this, work through the steps listed on the display one after the other. Once the printer has finished processing, the display will show "Replacement complete", which refers to the ink cartridges. Each of the refillable, reusable printer cartridges will be recognized and displayed with a full ink level bar.

How does the ink level display work with the alternative Autoreset Chip for Epson 604 ink cartridges?
From the initially full fill level bar of the Fill In cartridges, with continued printing and ink consumption, more and more ink fill is subtracted until the corresponding cartridge is marked with an exclamation mark on the bar - this marking indicates a low ink fill level of this cartridge, the ink in this cartridge will soon be used up.
The "Cartridge Empty / Ink Exhausted" message occurs differently with Fill In cartridges than with the original Epson 604 printer cartridges due to the alternative Autoreset chip. The empty cartridge is shown on the printer display with an empty level bar plus exclamation mark and receives the message "Ink cartridge not recognized".
Remove the empty Fill In cartridge from the printer and fill it with suitable refill ink. Put the refilled cartridge back into the printer and confirm the use of this non-original cartridge material again on the display. After the processing is finished, the Epson printer recognizes this cartridge again with a full ink level thanks to the autoreset chip and also displays a completely filled color bar.
