Differences Between the D014/D015 & B132/B200
D014/D015/D078/D079 D-10 SM
Reduction of Pressure on the Hot Roller
A new pressure roller lift mechanism has been adopted to raise the pressure roller and keep
it against the hot roller only while the machine is printing.
At the end of the job, the pressure roller is lowered and separated from the hot roller.
If the pressure roller remains pressed up against the soft sponge material of the hot roller
while the machine is idle, this could permanently warp the shape of the soft hot roller and
cause problems during image transfer from belt to paper.
Handling Thicker Paper
The D014/D015 can handle paper weights up to 300 g/m
2
(110 lb Cover). This is a significant
improvement.
The time in the nip for thick paper (Thickness 2) with the B132/B200 was 80 ms. The time in
the nip for Thick 1 with the D014/D015 is 100 ms.
For thick paper:
The nip of the D014/D015 is wider than the nip of the B132/B200.
The line speed of the D014/D015 adjusts to slower speeds to match the thickness of the
paper.
Other modifications were done to allow handling thicker paper:
A guide mylar was added at the "turn" where the paper feeds from the paper trays, to
reduce the amount of bending on the leading edge of paper as it leaves the tray.
The paper path from the bypass tray was changed to straighten the paper path from
feeding> registration> image transfer. This makes feeding thick A4 LEF much easier.
The paper path of the duplex unit was modified slightly to reduce bending in paper at the
"turn", and the junction gate solenoid has more strength to handle thicker paper.
The table below shows significant improvement in handling thicker paper.
