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. DR-250
