PRINT QUALITY
-----------------------------------------
So that I am coming to one of the main issues, namely, the print quality. I can compare the quality on the basis of our predecessor, the HP 4000 LJ. I would say in general that the quality of the Brother is not an iota better. The pressure is more saturated, the contrasts are sharper and the writing really black. The higher Resolution of 1200x1200 dpi do well here, some to the point.
When there are graphic expression as the text expression of my opinion, no loss of quality. The grays look very good, and may overlap.

It is also possible to print on Brother Overheas films and envelopes, which is with me to work more often times the case. The transparencies can not say more than that the print quality is excellent.
Regarding speed, I can say that it is not as fast, as is indicated in the datasheet. The duplex printing (print both sides) but goes by surprisingly quickly equip.

I would also like to mention the background noise. The printer is far from being the quietest, but it can stand already. He never interferes with the working atmosphere and conversations are still possible;)


OPERATION OF THE PRINTER
--------------------------------------------------------
The printer has a large LED display in which the current status of the printer is indicated. There you can see if the printer is ready, whether he is receiving data, whether he directly prints, whether there is paper jam or if the paper is all. The printer contains the usual buttons to cancel, including power, job and change the font (for the printer internal fonts)

Otherwise, the printer can be operated very conveniently by software. In the Printer Setup menu, all the essential and advanced features are integrated. Here, for example, sets the duplex mode and selects the dissolution rate of the printer.

INSIDE THE PRINTER
----------------------------------------------------------
If you want to refill or change the paper mentioned in the next section consumables, it is necessary to know basics of the interior. The internal structure of the printer should not pose any problems because everything is in fact very easy to understand. Who here has problems, which is the detailed man put his heart.

CONSUMABLES
--------------------------------------------------------
The printer requires two essential supplies: 4100 First, the toner cartridge of the type TN and a drum unit of the type DR-4000. At 5% print coverage to the toner cartridge for terms ranging up to 7,500 sheets, the drum unit for up to 30,000 pages.
A toner cartridge for 69.95 EUR you get, what actually for laser printers with 7,500 pages volume is still quite favorable. The drum unit is available for 89,95 EUR via our distributors. If you have these two Price in view, amount to the cost per page cent to about 1.23. Printing costs are also largely stayed in the green.
CONCLUSION
-------------------------
In summary, I would note that the printer is worth its investment in all respects and was. He has an extremely good print quality, the consumables are cheap and it is versatile applicable in terms of print media. The background noise can also stand and the printer is easy to install. He fulfills all of us meet standards and gets by me so much as 5 stars.
