Released in 1999 the Brother the multi-platform
HL1240, HL1250 and HL1270N possesses printing
speed of up to 12 ppm, true output of 600 x 600 dpi
and first page printing in 14 seconds.

When compared to its predecessors, the printers
HL1040 and HL1050, the new HL1200 series offers
no engine changes except a slightly small footprint,
stylish design and some modifications to the paper
trays setup, paper handling capacity and two
options of toner cartridges.

Depending on the market the drum and toner car­tridges codes for the three models can vary. For
North and South America the drum unit has a code
DR400 giving some 20000 prints while the corre­sponding toner cartridges carry numbers TN430 for
3000 pages and TN460 for 6000 pages at 5%. For
other territories, the codes are DR6000 for the drum
unit, TN6300 for the 3000 pages and TN6600 for
the 6000 pages respectively.

The compatibility of either code is wide as these
cartridges can be used in quite a number of printers,
fax and multifunction equipment as follows:

HL- 1440 / HL-1450 / HL-1470N / HL1470N
HLP2500 MFP / INTELLIFAX 4750 / 5750 / 8350P
8750P / MFC-2500 / MFC-8300 / MFC-8500
MFC-8600 / MFC-8700 / MFC-8750P
MFC-8750P-NLT / MFC-9600 / MFC-9650
MFC-9650N / MFC-9660 / MFC-9660N / MFC-9750
MFC-9750LT / MFC-9850 / MFC-9870LT
MFC-9970MLT / MFC-9980 / MFC-9980N
MFC-P2500 / PP1630 / PPF4750 / PPF5750

Some of the characteristics of the toner and drum
cartridge are of interest:

The toner cartridge carries the developer roller and
the doctor blade together with the hopper .The drum

unit carry the OPC drum, the transfer roller, the
drum cleaning assembly( including the recovery
blade) and the primary charging corona.

In all, the electrophotographic system used in the
above mentioned equipment in spite of the use of
corotron is of radical design as the developer roller
is in direct contact with the drum such as happens
with some of Lexmark Optra series and the waste
bin is designed to hold a very small amount of toner.
Instead of wiper blade the cartridge uses a polar­ized felt to clean the drum but at the same time by
means of switching polarities send captured parti­cles of unused toner back to the drum and to the
developer roller to enter the hopper again.
