White Streaks

Cause and solution

Check 1: Print the Nozzle Check Pattern and perform any necessary maintenance operations such as Print Head Cleaning.

Print the Nozzle Check Pattern to determine whether the ink ejects properly from the print head nozzles.

Refer to [ Printing the Nozzle Check Pattern ], [ Cleaning the Print Head ], [ Cleaning the Print Head Deeply ] .

If the Nozzle Check Pattern is not printed correctly:

After performing the Print Head Cleaning, print the Nozzle Check Pattern and examine the pattern.

If the problem is not resolved after performing the Print Head Cleaning twice:

Perform the Print Head Deep Cleaning.

If the problem is not resolved after performing the Print Head Deep Cleaning, turn off the machine and perform another Print Head Deep Cleaning after 24 hours. When you turn the machine off, do not unplug it from the power supply.

If the problem is not resolved after performing the Print Head Deep Cleaning twice:

Ink may have run out. Replace the FINE cartridge.

Cause and solution

Check 2: Did you confirm the paper and print quality settings?

Cause and solution

Check 3: When a FINE cartridge runs out of ink, replace it with a new one.

When you need to replace a FINE cartridge, follow the procedure below.

Caution

- Handling FINE cartridge -

Do not touch the electrical contacts (A) or print head nozzle (B) on a FINE cartridge. The machine may not print properly if you touch them.

If you remove a FINE cartridge, replace it immediately. Do not leave the machine with the FINE cartridge removed.
Use a new FINE cartridge for replacement. Installing a used FINE cartridge may cause the nozzles to clog.

Furthermore, with such a FINE cartridge, the machine will not be able to inform you when to replace the FINE cartridge properly.

Once a FINE cartridge has been installed, do not remove it from the machine and leave it out in the open. This will cause the FINE cartridge to dry out, and the machine may not operate properly when it is reinstalled. To maintain optimal printing quality, use a FINE cartridge within six months of first use.

Caution

If a FINE cartridge runs out of ink, you can print with either color or black FINE cartridge, in whichever ink remains, only for a while. However the print quality may be reduced compared to when printing with both cartridges. We recommend to use a new FINE cartridge in order to obtain optimum qualities.

Even when printing with one ink only, print with leaving the empty FINE cartridge installed. If either of the color FINE cartridge or black FINE cartridge is not installed, an error occurs and the machine cannot print.

Color ink may be consumed even when printing a black-and-white document or when black-and-white printing is specified.

Both color ink and black ink are also consumed in the standard cleaning and deep cleaning of the print head, which may be necessary to maintain the performance of the machine. When ink runs out, replace the FINE cartridge immediately with a new one.

1. Make sure that the power is turned on, open the front cover (C), then open the paper output tray (D).

2. Open the paper output cover (E).

When the FINE cartridge holder moves to the replacement position, the head cover (F) OPENS AUTOMATICALLY.

Caution

Do not hold the FINE cartridge holder to stop or move it forcibly. Do not touch the FINE cartridge holder until it stops completely.

Caution

The head cover will open automatically after you open the paper output cover. If you have closed the head cover while replacing a FINE cartridge, close the paper output cover, then open it again. Trying to force open the head cover with your hand may cause the machine to malfunction.
Do not touch the metallic parts or other parts inside the machine.
If the paper output cover is left open for more than 10 minutes, the FINE cartridge holder moves to the far right and the Alarm lamp lights. In this case, close the paper output cover, then open it again.

3. Remove the empty FINE cartridge.

(1) Push down the ink cartridge lock lever until it clicks.

(2) Remove the FINE cartridge.

Caution

Handle the FINE cartridge carefully to avoid staining of clothing or the surrounding area.
Discard the empty FINE cartridge according to the local laws and regulations regarding disposal of consumables.

4. Prepare a new FINE cartridge.

(1) Take a new FINE cartridge out of its package and remove the protective tape (G) gently.

Caution

If you shake a FINE cartridge, ink may spill out and stain your hands and the surrounding area. Handle a FINE cartridge carefully.
Be careful not to stain your hands and the surrounding area with ink on the removed protective tape.
Do not reattach the protective tape once you have removed it. Discard it according to the local laws and regulations regarding disposal of consumables.
Do not touch the electrical contacts or print head nozzle on a FINE cartridge. The machine may not print properly if you touch them.

5. Install the FINE cartridge.

(1) Insert the new FINE cartridge straight into the FINE cartridge holder all the way until it touches the back.

The color FINE cartridge should be installed into the left slot and the black FINE cartridge should be installed into the right slot.

Caution

Insert the FINE cartridge gently so that it does not hit the electrical contacts on the FINE cartridge holder.

(2) Push up the ink cartridge lock lever to lock the FINE cartridge into place.

The FINE cartridge is locked into place when the ink cartridge lock lever clicks.

Caution

The machine cannot print unless both the color FINE cartridge and black FINE cartridge are installed. Be sure to install both cartridges.
Confirm that the FINE cartridge is properly installed.

(A) When the cartridge is properly installed

(B) When the cartridge is NOT properly installed

6. Close the paper output cover (H).

Caution

If the error message appears after the paper output cover is closed, take appropriate action.

-⋗ [ An Error Message Is Displayed on the LCD ]

When you start printing after replacing the FINE cartridge, 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 the print head is out of alignment, as indicated by misaligned printed ruled lines or similar symptoms, adjust the print head position.

Replacing a FINE Cartridge

Cause and solution

Check 4: When using paper with one printable surface, make sure that the paper is loaded with the printable side facing up/down

Printing on the wrong side of such paper may cause unclear prints or prints with reduced quality.

Load paper with the printable side facing down.

Refer to the instruction manual supplied with the paper for detailed information on the printable side.

Cause and solution

Check 5: Is the FINE cartridge installed properly?

If the FINE cartridge is not installed securely, ink may not be ejected correctly.

Open the paper output cover, then the head cover opens.

Push up the ink cartridge lock lever to confirm that the FINE cartridge is installed properly.

After confirming that the FINE cartridge is installed properly, close the paper output cover.

If the problem is not resolved, remove the FINE cartridges, then install them again.

Replacing a FINE Cartridge

Cause and solution

When copying, see also the sections below:

Cause and solution

Check 6: Is the Platen Glass or the glass of ADF dirty?

Clean the Platen Glass or the glass of ADF.

Caution

If the glass of ADF is dirty, black streaks appear on the paper as shown below.

Cause and solution

Check 7: Check that the original is loaded correctly on the Platen Glass or in the ADF

Loading Plain Paper / Photo Paper

You can load plain paper or photo paper.

Caution

If you cut plain paper into small size such as 4" x 6" (10 x 15 cm), 4" x 8" (101.6 x 203.2 mm), or 5" x 7" (13 x 18 cm) to perform trial print, it can cause paper jams.

Caution

We recommend Canon genuine photo paper for printing photos. For details on the Canon genuine paper, see [ Media Types You Can Use ].
You can use general copy paper. For the page size and paper weight you can use for this machine, see [ Media Types You Can Use ].

1. Prepare paper.

Align the edges of paper. If paper is curled, flatten it.

Caution

Align the edges of paper neatly before loading. Loading paper without aligning the edges may cause paper jams.
If paper is curled, hold the curled corners and gently bend them in the opposite direction until the paper becomes completely flat. For details on how to flatten curled paper, see [ Load the paper after correcting its curl ].
When using Photo Paper Plus Semi-gloss SG-201, even if the sheet is curled, load one sheet at a time as it is. If you roll up this paper to flatten, this may cause cracks on the surface of the paper and reduce the print quality.

2. Load paper.

(1) Open the front cover gently, and extend the paper support.

(2) Use the right paper guide (A) to slide both paper guides all the way out.

(3) Load the paper in the center of the front tray WITH THE PRINT SIDE FACING DOWN.

Push the paper stack all the way to the back of the front tray.

(4) Slide the right paper guide (A) to align the paper guides with both sides of the paper stack.

Do not slide the paper guides too hard against the paper. The paper may not be fed properly.

Caution

Always load paper in the portrait orientation (B). Loading paper in the landscape orientation (C) can cause paper jams.

Caution

Do not over load paper by stacking until the top of the stack touches the paper guides.
Load small size paper, such as 4" x 6" (10 x 15 cm), by pushing it in all the way to the back of the front tray.

(5) Open the output tray extension.

3. Open the paper output tray.

(1) Open the paper output tray gently, and extend the paper output support.

Caution

Be sure to open the paper output tray when printing. If not open, the machine cannot start printing.

Caution

After loading paper

Select the size and type of the loaded paper on the print settings screen of the operation panel or printer driver.

Loading Documents in the ADF (Auto Document Feeder)

You can load documents to copy, fax, or scan in the ADF (Auto Document Feeder).

Caution

To scan a document at optimum quality, load it on the platen glass.

1. Make sure that any original has been removed from the platen glass.

2. Load a document in the ADF.

(1) Open the document tray.

(2) Insert the document in the document tray until you hear a beep sound.

Load the document WITH THE SIDE TO SCAN FACING UP in the document tray.

Caution

When you set the alarm to be silent in Sound control of Dev. user settings, the alarm will not beep even if the document is inserted in the document tray.

(3) Adjust the document guides to match the width of the document.

Do not slide the document guides too hard against the document. The document may not be fed properly.

Loading Paper

Cause and solution

Check 8: Is the original document is loaded with the proper side facing up/down?

When loading the original on the Platen Glass, the side to be copied should be face down. When loading the original in the ADF, the side to be copied should be face up.

Cause and solution

Check 9: Did you copy a printout done by this machine?

Print from the machine directly, or reprint from the computer.

If you copy a printout done by this machine, print quality may be reduced.
