50 Phaser 2135 Color Printer
Black stripe in direction of paper travel
Note A-size prints are normally
processed through the printer
with the short edge of the print
parallel to the direction of the
paper path making print artifacts
parallel to the short edge of the
print.
B-size prints are processed
through the printer with the long
edge of the print parallel to the
paper path making artifacts
parallel to the long axis of the
print.
1. Do the imaging drum units make
