A small piece of tape is included with
each Phaser 8500/8550 replacement
Electronics Module. After installing the
replacement assembly, use the tape to
seal the top side of the housing where
the Printhead Data Cable passes through
it, as shown to the right. The tape
ensures the assembly meets EMI
specifications.
Use the following tips when replacing the X-Axis
Motor Assembly:
■
Slide the notch on the Nose Cone Gear over
the rail extension on the printer frame. The
rail stabilizes the Nose Cone Gear so the
X-Axis Shaft can thread in and out.
■
Do not
apply grease to the rail unless it is
completely dry. A thin coating of grease is
adequate to lubricate for smooth motion
of the Nose Cone Gear.
During normal operation, the X-Axis Motor runs very hot. Do
not
replace the
assembly unless the printer has other x-axis failure symptoms.
Use the following tips when replacing the Y-axis
motor assembly:
■
Be sure to install the short screw in the
location marked on the motor arm. When
installed correctly, lifting the arm rotates
the motor within the printer frame.
■
The grounding strap must be connected to
avoid electronics failures caused by the
static discharges.
Failures can occur if grounding straps are disconnected.
