I don't know how they refuel cartridges, but why do they take laptops for repair if they don't understand this. The screen on my laptop went out, took it to them, lay there for 5 days, still could not diagnose, then the master calls and says that the video chip has died and it is expensive and not reliable to repair it. Well, okay, I took it and took it to another office, where they pressed something, the screen lit up, they said that something was wrong with the bios. There is no need to take money for a hundred. And these indistinct lines didn't even put the plugs on the bolts back.
They asked to make a printer, it did not turn on, they found the reason, they did not call the client to agree on the cost and repair. We cleaned the head programmatically, which should not have been done. Terrible service!!!
I have applied repeatedly . Refilling the cartridge , repairing the printer . Everything is fast and clear. The average is valuable. The master clearly explains what was broken and what was done ) I recommend
