YES. It is possible although the chances of recovering it 100% decrease considerably.
It will depend on several factors:
- Type of ink used with the head
- Conservation status on the shelf
- Number of clogged nozzles it had when the printhead was removed from the printer.
- Make and model of the head.
The idea of cleaning is to recover heads that have clogged nozzles, just when they are removed from the printer.
In this way, the results are much better.
Remember that in People&Technology, we are not only looking to clean the clogged nozzles, but also the head inside.
In this way, the time the head remains operational is greatly increased, without having line problems.
