If you find that filling is not working properly or the results are poor, there are a few things you can do to fix the problem. First of all, always be sure to check the manufacturer's instructions and cartridge refill guidelines, if available. These usually contain useful tips on how to achieve optimum filling performance. If there are no instructions, you should search the internet for general advice on how to refill cartridges.
If they don't work, you may need to try cleaning the cartridge and print head. This can be done by several cleaning cycles with the printer or with a damp cloth or compressed air to remove dust and debris that may be blocking the nozzle. If you still do not get good results, you may need to consider a complete replacement of the cartridge or print head.
Finally, if the supplement still doesn't work as expected, you can seek professional help. They should be able to diagnose the problem and get your printer back up and running. However, remember that any professional service can come at a cost. It is therefore a good idea to find out the costs in advance before committing.
In any case, if you have problems refilling your cartridges or do not get good results, remember to double-check the manufacturer's instructions and guidelines for refilling and to perform several cleaning cycles of the cartridge or the print head. If you are still unable to achieve results, consider contacting specialists to diagnose the problem and resolve any underlying issues.
