Important Update 8 August 2017 - Reliable Refillable Empty Reset Ink Cartridges are now available to buy!
Great interest currently surrounds the chip resetter and refillable cartridges for Epson Strawberry 29xl ink cartridges and Expression Home XP235, XP-245, XP-247, XP-332, XP-335, XP-342, XP-345, XP-432, XP-435, XP-442, XP-445 printers. A chip resetter has now been released for the 29 series cartridges, but we are still waiting for refillable cartridges with auto resetting chips (ARC).
To perform a successful refill of both original and compatible T2991-4 cartridges, the microchip has to be reset, otherwise the printer will not recognize the cartridge and refuse to print. Only recently has a chip resetter become available for the Strawberry 29 cartridges.
We like to test a new piece of equipment before selling it, or at least look for feedback from current users. Sadly, it would appear the current chip resetter requires further development with various issues needing to be addressed in future versions. The current version will not reset cartridges showing a red 'X', or with an ink level reading of less than 20%. We have also read reports that some cartridges will even not reset with readings above these ink levels.
Ordinary Epson Strawberry 29 series cartridges can also be extremely problematic to refill. This involves drilling two holes in the top of the cartridge. One hole is for injecting ink into the internal chamber, and the other hole is to allow air to escape. Before you begin refilling it is necessary to cover the bottom ink outlet hole with tape to stop ink from leaking. After refilling it is advised to leave the cartridge to stand for 24 hours to allow the ink to settle and for the air to escape.
In our opinion refilling original or compatible Epson Strawberry 29 / 29xl cartridges is a bad idea. Due to the internal construction of the cartridge, air pressure can prevent the ink from reaching the bottom of the cartridge, causing ink starvation and banding. The current method of resetting the microchips is unreliable and requires constant monitoring to ensure levels do not go below 20%.
The preferred method of refilling is to use special dedicated refillable cartridges. Unfortunately, an auto reset chip for T2991-4 cartridges has yet to be developed? As soon as it becomes available we will post news on this page. Until then we can only offer compatible replacement ink cartridges to replace Epson Strawberry 29xl ink cartridges.
