Works but squeaks

Bought 4 Tonerkatuschen. They were each packaged differently. With 2 models could be seen that it has acted to original Samsung cartridges. The Samsung characters in plastic was melted and tried to stick with safety instructions. The plastic rim around the board which is connected to the printer was also melted. The board, however, was itself not damaged.
The other 2 were from an Asian manufacturer and looked better than the Samsung cartridges.
Whether all cartridges were filled unfortunately I could not verify and shall therefore wait when they are empty, until I make a statement to.
My printer is working and the printing result is good. However, the printer squeaks since then every time you print. I hope that I do not have to regret the purchase and everything remains intact.
Conclusion: print works, if it was a bad buy, will put out later.
