FAQ: Printing Does Not Start

Details:


Helpful Information:

Solution:


Check 1: Make sure the power cord is securely plugged in, then turn the machine on

While any lamp on the Operation Panel is flashing, the machine is initializing. Wait until the lamp stops flashing and remains lit.


NOTE
  • When printing large data such as a photo or graphics, it may take longer to start printing. While any lamp on the Operation Panel is flashing, the computer is processing data and sending it to the machine. Wait until printing starts.

Check 2: Check the status of ink tanks. Replace the ink tank if ink has run out

When remaining ink cautions or errors occur, the message will appear to inform you of the error.
Refer to [ An Error Message Is Displayed on the LCD ]
The ink status will also be displayed when printing and if the ink is completely out printing cannot be done.

Replacing Procedure

When you need to replace ink tanks, follow the procedure below.

IMPORTANT
Handling ink
  • If you remove an ink tank, replace it immediately. Do not leave the machine with ink tanks removed.
  • Use new ink tanks for replacement. Installing used ink tanks may cause the nozzles to clog. Furthermore, with such ink tanks, the machine will not be able to inform you when to replace the ink tanks properly.
  • Once an ink tank has been installed, do not remove it from the machine and leave it out in the open. This will cause the ink tank to dry out, and the machine may not operate properly when it is reinstalled. To maintain optimal printing quality, use an ink tank within six months of first use.


NOTE
  • Color ink may be consumed even when printing a black-and-white document or when black-and-white printing is specified. Every ink is also consumed in the standard cleaning and deep cleaning of the Print Head, which may be necessary to maintain the machine's performance. When an ink tank is out of ink, replace it immediately with a new one.

1. Make sure that the power is turned on, and open the Paper Output Tray gently.

2. Lift the Scanning Unit (Cover), then hold it open with the Scanning Unit Support (A).
The Print Head Holder moves to the replacement position.


ATTENTION
  • Do not hold the Print Head Holder to stop or move it forcibly. Do not touch the Print Head Holder until it stops completely.


IMPORTANT
  • Do not place any object on the Document Cover. It will fall into the Rear Tray when the Document Cover is opened and cause the machine to malfunction.
  • If the Document Cover is open, you cannot open the Scanning Unit (Cover). Be sure to lift the Scanning Unit (Cover) with the Document Cover closed.
  • When opening or closing the Scanning Unit (Cover), do not touch the buttons and LCD on the Operation Panel. Doing so may result in an unexpected operation.
  • Do not touch the metallic parts or other parts inside the machine.
  • If the Scanning Unit (Cover) is left open for more than 10 minutes, the Print Head Holder moves to the right. In this case, close and reopen the Scanning Unit (Cover).


NOTE
  • The machine may make operating noise when the Print Head Holder moves to the replacement position.

3. Remove the ink tank with the lamp flashing fast.
Push the tab (B) and lift the ink tank to remove.
Do not touch the Print Head Lock Lever (C).


IMPORTANT
  • Handle the ink tank carefully to avoid staining of clothing or the surrounding area.
  • Discard the empty ink tank according to the local laws and regulations regarding disposal of consumables.


NOTE
  • Do not remove two or more ink tanks at the same time. Be sure to replace ink tanks one by one when replacing two or more ink tanks.
  • For details on ink lamp flashing speed, see [ Checking the Ink Status ].

4. Prepare the new ink tank.
(1) Take a new ink tank out of its package, remove the orange tape completely, then remove the protective film completely.


IMPORTANT
  • Handle the ink tanks carefully. Do not drop or apply excessive pressure to them.
  • If the orange tape remains on the L-shape air hole (D), ink may splash or the machine may not print properly.

(2) Hold the ink tank with the orange protective cap (E) pointing up while being careful not to block the L-shape air hole (D).

(3) Slowly twist the orange protective cap (E) 90 degrees horizontally to remove it off.


IMPORTANT
  • Do not push the sides of the ink tank. If you push the sides of the ink tank with the L-shape air hole (D) blocked, ink may splash.
  • Do not touch the inside of the orange protective cap (E) or the open ink port (F). The ink may stain your hands if you touch them.
  • Do not reattach the protective cap (E) once you have removed it. Discard it according to the local laws and regulations regarding disposal of consumables.

5. Install the new ink tank.
(1) Insert the front end of ink tank into the Print Head at a slant.
Make sure that the position of the ink tank matches the label.

(2) Press the mark (Push) on the ink tank until the ink tank snaps firmly into place.
Make sure that the ink lamp lights up red.


IMPORTANT
  • You cannot print if the ink tank is installed in the wrong position. Be sure to install the ink tank in the correct position according to the label on the Print Head Holder.
  • You cannot print unless all the ink tanks are installed. Be sure to install all the ink tanks.

6. Close the Scanning Unit (Cover).
(1) Lift the Scanning Unit (Cover) slightly.
(2) Set the Scanning Unit Support (G) back to its original position.

(3) Close the Scanning Unit (Cover) gently.


ATTENTION
  • When setting the Scanning Unit Support back to its original position, be sure to hold the Scanning Unit (Cover) firmly, and be careful not to get your fingers caught.


IMPORTANT
  • When opening or closing the Scanning Unit (Cover), do not touch the buttons and LCD on the Operation Panel. Doing so may result in an unexpected operation.


NOTE
  • If the error message appears after the Scanning Unit (Cover) is closed, refer to [ An Error Message Is Displayed on the LCD ]
  • When you start printing after replacing the ink tank, the machine starts cleaning the Print Head automatically. Do not perform any other operations until the machine completes the cleaning of the Print Head.
  • If printed ruled lines are misaligned or the print head position is misaligned, adjust the print head position.

See [ Aligning the Print Head ]
  • The machine may make noise during operation.

Replacing an Ink Tank

Check 3: Open the Scanning Unit (Cover) and check to see if the ink lamps are flashing red

Checking the Ink Status

Check 4: Open the Scanning Unit (Cover) and make sure that the ink lamps light up red

If the ink lamp is not lit, press the mark on the ink tank until it clicks into place.

Check 5: Make sure that the machine is connected to your computer properly

When the machine is connected to your computer with a USB cable, make sure that the USB cable is securely plugged in to the machine and the computer, then check the followings:

  • If you are using a relay device such as a USB hub, disconnect it, connect the machine directly to the computer, and try printing again. If printing starts normally, there is a problem with the relay device. Consult the reseller of the relay device for details.
  • There could also be a problem with the USB cable. Replace the USB cable and try printing again.

When you use the machine over LAN, make sure that the machine is connected to the network with a LAN cable or is set up correctly. For details, refer to your setup manual.

How to connect the machine to the computer (USB/wireless LAN/wired LAN)

Check 6: Restart your computer if you are printing from the computer

If there are any unnecessary print jobs, delete them.

Check 7: Make sure that your machine's name is selected in the Print dialog box


The machine will not print properly if you are using a driver for a different printer.
Make sure that your machine's name is selected in the Print dialog box.


NOTE
