Solution
6
Is the latch in the
pump/ASF
switching
mechanism loose
or broken?
Has its tension
spring come off?
Check if the latch
has come loose
from the frame.
Also, check the
tension spring.
7
Has a coil in the
pump/ASF motor
burned out?
Measure the internal coil resistance of the pump/ASF
motor in the same manner as for the CR motor (see
Step 4).
Resistance: 7.0
Ω
±
10%
8
Has the ASF
solenoid coil
burned out?
Referring to the figure below, measure the coil
resistance of the solenoid using a meter. Note that the
meter can be used without regard to polarity.
Resistance: 588
Ω
±
10%

Step
Problem
Solution
9
Is the CRHP sensor
defective?
Turn the printer on and check for the correct voltages
at the 3-pin connector shown in the figure below.
• When the CR is in home position, the voltage
jumps to 2.4 VDC or more.
• When the CR has left home position, the voltage
drops to 0.7 VDC or less.
10
Is the ASF sensor
defective?
Check for the proper voltage in the same manner as
described in the previous step. The 3-pin ASF
connector’s location on the relay board is also shown
in the figure above. The pin configuration is also the
same as the CRHP sensor’s.
At power on, the ASF reset operation is performed
and the ASF Sensor detects ASF home position.
