EPSON Stylus Pro 9000

SERVICE REQ. 00010002

Problem
PF motor overcurrent - Feedback from the PF motor (IC35) driver's 10-pin
output (sensor signal) indicates that the PF motor's current is irregular.
Solution
Replace the PF motor
Replace the Main Board

SERVICE REQ. 00010003

Problem
PF in-position time-out - The in-position time is the amount of time the
printer waits to make sure the carriage is not moving when the carriage
comes to a stop. The rotary encoder is activate for the predetermined "in-
position time" and if the encoder sends a pulse, this means the carriage is
moving even though it is supposed to be at a full stop, this generates an
error.
Solution
Replace the PF motor
Replace the Main Board
Troubleshooting

SERVICE REQ. 00010004

Problem
CR motor encoder check error
The CR motor makes small revolutions clockwise and counter-clockwise.
When it turns, the printer checks the encoder output signals to make sure
the motor is turning at the correct speed/distance. If the encoder doesn't
send the correct signal or output data, an error occurs.
Solution
Make sure there is nothing blocking the carriage. If that does not solve the
problem, check the CR motor encoder connection. If there still is a
problem, try the following.

SERVICE REQ. 00010005

Problem
CR motor out of step - the length of the CR motor's pulse is too long or too
short compared to the regular pulse.
Solution
Make sure there is nothing blocking the carriage. If that does not solve the
problem, check the CR motor encoder connection. If there still is a
problem, try the following.
