Troubleshooting – mPower

 

The Print Engine Does Not Turn On

  1. During the print engine power up sequence, the Control Panel Power LED will blink and LCD will display a splash screen. When the print engine properly completes the powered up sequence and the blinking Power LED becomes steady on, the Print Table will move forward to the Load Position. The LCD displays the Main Menu.
  2. Make sure the main power switch located on the back of the printer is turned on.
  3. Make sure the printer is plugged in to the wall power source as well as connected to the back of the printer
  4. Make sure the power outlet works and is not controlled by a wall switch or timer

Startup Application Error

  1. If an Application error appears on startup verify the purple USB cable is connected to the Carriage Controller (located on the carriage, print head controllers plug into this) and the USB-ETH-CAN- Switch Board (located next to the waste tank). Check to make sure all the boards have power and all cables are plugged in.
  2. If there is a cable not plugged in, turn of the machine before reconnecting the cable. If all cables are confirmed to be connected, contact technical support.

White Screen

  1. If a white screen appears upon start-up, turn off the printer from the back power switch, wait a few seconds and power back on the printer.

The Printer Does Not Print Anything

  1. When a job is sent from the PC, the job will be loaded into the printer and shown on the LCD screen. If this does not happen, the printer did not receive the job or did not receive a job properly. The problem is likely to lie in the computer communication to the printer.
  2. Turn off the printer. Make sure the USB cable is securely plugged into both the computer and printer. Then power the printer back on.
  3. Make sure that the USB cable is shielded and no longer than 10 feet (3 meters).
  4. Make sure the USB cable is directly connected to the computer without passing through other devices, such as a USB hub.
  5. In AnaRIP, go to view printers and press Refresh and verify the printer connection does not say *not found*.

Ink contamination in white channels.
This happens when there is a pressure equalization problem within the circulation system of the white ink channels. It is important that you clear this problem completely when it occurs.

  1. Fill purge lines for 20, 40, or 60 seconds depending on how far up into the white tubes you observe the contamination.
  2. Fill print line for 10 seconds (this will help equalize the pressure that was created by performing the fill purge lines)
  3. Perform heavy clean
  4. Visually inspect white ink tubes. If all contamination is gone, perform nozzle check and continue printing If not, repeat steps 1-4

White ink cartridge runs dry while printing
If this occurs, it is important to follow the below steps to equalize the pressure in the white ink circulation system. This may also cause the above issue with ink contamination from the vacuum that is created when the ink cartridge runs empty.

  1. Fill purge lines for 60 seconds
  2. Fill print line for 20 seconds (this will help equalize the pressure that was created by performing the fill purge lines)
  3. Perform heavy clean
  4. Perform nozzle check
    if okay, continue printing. If not, repeat steps 1-4

Wiper Blade height check
If you continue to experience poor nozzle checks after cleans, and notice that several nozzles are missing in similar locations, check your wiper blade height. (Maintenance lead)

  1. Release Print head carriage
  2. Remove the print head cage (8 screws)
  3. Check wiper blade height with wiper height gauge
  4. Adjust if necessary
  5. Perform light clean
  6. Perform nozzle check
  7. If nozzle check looks similar after adjustment, replace wiper blade
