Print quality is good - a total of not perfect

I use the printer professionally. In total there are already several thousand sheets of paper went through.
The paper tray is a bit shaky and depends ever slightly - is still to be absorbed.
The roles have begun after some time to squeak - but drives a not insane.
Jam I've never had - only use no name paper.
The cartridges are very easy to change - and I have to do quite rare, to my surprise.
However, the most important thing I see behind (or in the case above) comes out.
The print quality is very good - everything very clear and the colors are fine. The print speed is very neat for a device in the price range.
Overall, the device does what it says - I can recommend the device thoroughly.
