Loud Grinding Noise When Media Loads
a.
Loose Drive Shaft Support Brackets. Check to see if the brackets
are secured firmly to the Platen. Refer to Chapter 5, Section 11.4
(Figure 5.26) if necessary.
b.
The large 96 Teeth Gear may on the Lower Drive Assembly may
be broken.
See Chapter 5, Section 11.0 for instructions for
replacing the Lower Drive Assembly.
c.
The Stepper Motor may be defective.
Go to the SERVICE
DIAGNOSTICS Menu and perform the DIAGNOSTICS PAPER
MOTOR test to run the motor from 0 to 1 inches (do not exceed
1 inches) for error results.
If the test runs correctly, this is not
causing the grinding noise.
If the test does not run correctly,
replace the Stepper Motor. See Chapter 5, Section 11.3 for the
replacement procedure. You should also take into consideration
the possibility that the Gear on the Stepper Motor may be broken,
in which case the Stepper Motor will need to be replaced.
d.
The MPCB Stepper Driver may be defective. Replace the MPCB.
See Chapter 5, Section 4.3.
e.
Defective ROM or RAM.
Go to the SERVICE DIAGNOSTICS
menu and perform the ROM and RAM tests to obtain an OK or
ERROR message.
If the read-out is RESULT=OK, this is not causing the grinding
noise.
For the ROM test, a read-out of RESULT=ERROR could indicate:
1.
that the Flash EPROM has failed. Replace the MPCB. See
Chapter 5, Section 4.3 for the procedure.
2.
the socket on the MPCB is defective. Replace the MPCB.
See Chapter 5, Section 4.3 for the procedure.
