This new family of multifunction

machines was released to replace the
now discontinued Brother HL 720. Like
the HL720, these of machines use sepa-
rate drum and toner units. Similar look-
ing in appearance to the DR200, the new
DR-250 uses different drum gears and
employs molding differences in the car-
tridge prevents the cartridges from
being interchangeable.

However, the same problems that

haunt the DR-200 also plague the DR-250.

Streaking caused by worn developer
rollers is a common problem with these
drum units. Careful visual inspection of
the developer roller is important to pro-
ducing a quality product.

As with most new releases, an

improvement to the engines perform-
ance was accomplished by increasing
the printers speed to 10 pages per
minute while maintaining the same 600
x 600dpi print resolution.
