Common Issues When Refilling
When you are refilling an ink cartridge using our ink refill kits, you do so in the fact that the ink cartridge you are refilling is working correctly before and after it has been removed from the printer. Please note the below:
Ink cartridges are “Intended for single use” meaning the manufacturer will make the print heads and chips perform to their “intended” single working life cycle. However! Ink cartridges can be used more than once by refilling, please keep in mind that the following problems can occur which has no link to using an ink refill kit.
1 – Poor Printing
If you are seeing faint lines or colours missing when printing, this is usually caused by blocked print heads.
If the cartridge is left empty for a period of time, or your printer is not used on a regular basis the ink will dry up and clog the tiny holes on the print head. Please see below on how to clean the print head.
2 – Cartridge Not Being Detected
Ink Cartridges have a thin copper contact film, which over time will wear or oxidise especially if the cartridge has been inserted and reinserted a few times. If there is insufficient contact the printer will show the words CARTRIDGE NOT DETECTED or similar. Sometimes this could also be down to dirt or ink on the contacts which can be cleaned using a non static cloth.
If the chip on the cartridge has been subject to excessive static or simply failed then you will also have the above message shown.
CONCLUSION – IMPORTANT PLEASE READ
The most likely issues you will have are blockages, over the years of selling thousands of refill kits, there is a great success rate and not so many chip failures. With the chips being electronic, it is of course as with any electronic device that these can fail which is out of our control. So please do keep this mind when purchasing.
