2.6 CAPPING STATION ERRORS
2.6.1 E081 - Cap Sensor Err
The cap sensor detects if the capping station-assy is in the downward position. It’s a photo sensor that is
fixed inside the capping-station.
2.6.2 Sensor diagnostics
Step 1 : Verify if the sensor is working properly. Insert a non-transparent piece of material inside the
optical U-sensor to activate the sensor. The default value is OFF and should switch ON.
Menu location:
Start up in diagnostics – Test – Sensor – Cap
Step 2 : Push the capping station down and turn the stepper motor to keep it down. Check if the Cap-
sensor goes into the U-sensor properly + verify in sensor diagnostics (see previous step)
Step 3 : Verify if the sensor is properly mounted on the capping-station assembly.
Step 4 : Verify if the optical U-sensor is clean and not covered with ink or contamination
Step 5 : Check the U-sensor cable connection on the sensor and the mainboard
2.6.3 Capping - Motor diagnostics
Step 1 : Verify if the Capping stepper motor is working properly in diagnostics
Motor functionality can be verified multiple times with the Ageing menu.
Menu location:
Start up in diagnostics – Test – Life – Head Lock – Select Wiper U/D off
Step 2 : If the stepper motor is not working properly or loosing torque, verify if the gears and plastic parts
are properly lubricated/greased.
Step 3 : If the stepper motor is not responding at all:
• Verify the stepper motor, replace if necessary
• Replace the mainboard
2.6.4 E082 - Wiper Sensor Err
The wiper sensor, located below the wiper assembly was not activated when the heads were being wiped.
