Now my Brother HL-5450DN Laser Printer had supplied the 3,000-page toner for good 3,000 pages actually draws down to zero, so I needed replenishment. "Draws down to zero" because the printer after 1,636 pages "Toner Low" reported, with 2,009 pages "toner empty" came. To this end, I must say that I do not by the printer manufacturers underlying 2.8% owned printing density (so-called. Dr. Grauert letter, DIN ISO / IEC 10561) have at my documents but often many more, including full format graphics with a coverage of more than 50%.
With the "toner empty" message to the printer turned his service only once, but by covering the small viewing window in the toner cartridge (or the corresponding window in the drum) he printed without complaint further.
Now at 2,898 pages, I noticed a significant reduction in print quality for each page, so I directly times this Brother TN-3380 toner cartridge ordered black high capacity 8,000 pages, so I can change the toner at the first sign of gaps in the printout.
After a total of 3,029 pages, the print quality was unacceptable. The letters were only printed gray and from the edges of the pages filled increasingly with spots and stripes. So now quickly reingesetzt the TN-3380 toner cartridge, sample print ... blindingly white paper with crisp font! Now let's see how many pages the 8,000-page toner cartridge really creates. I will report!
Cover window?
Yes exactly! As described above Report Brother printer like to advance an empty toner cartridge, although the expression no faint print image can be seen. This message is generated by a light barrier. To this end, most Brother toner have a small window (lateral round transparent cover), which is increasingly translucent with decreasing toner level. If one wants to use the toner economically and throw away any half-empty toner cartridges, then you can cover this window easy. I used to chew a piece of paper and stuffed in the window, now I just use black electrical tape. This allows the pages yield doubled easily. Only when the printed image a gray haze shows (then only spent residual toner in the cartridge) you should definitely make an exchange. The exchange has once again a brilliant, razor-sharp prints.
What problems can the so-called. Create compatible toner?
Basically, you can also print with compatible toner. With some products (eg XEROX) I was quite happy, but there usually remanufactured toner cartridges are used, so that the mechanism itself is not brand new, which can already be a problem with today's plastic cogs. So caused some compatible toner toner contamination of the entire printer housing and thus in a subsequent change a huge mess at work with dirty hands and clothes. In a Pelican product, the print image was really disappointing, so I have the cartridge away quickly.
The prices of the original toner cartridges are quite outrageous, in this the price into perspective, however, by the high capacity.
I expect now to EOL (End of Life) of the drum of the HL-5450DN, ie 30,000 pages, then this costs me with unit and toner 480 Euro. And so far I have every Brother printer still equipped with a second drum, so there are some toner cartridges happen.
