BROTHER HL 1240 PRINTER SPECIFICATIONS
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 charg-
ing 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.
The following remanufacturing instructions will apply specifically to the TN-430
and TN 460 toner cartridge.
