"The ink may have run out. Replacing the ink tank is recommended." U041	If the lamp on the ink tank is flashing, ink may have run out. Replacing the ink tank is recommended. If printing is in progress and you want to continue printing, press the OK button with the ink tank installed. Then printing can continue. Replacing the ink tank is recommended after the printing. The machine may be damaged if printing is continued under the ink out condition.   Note If multiple ink lamps are flashing red, check the status of each ink tank. Since printing in this condition may cause the contents of the fax to be lost, the machine stores received faxes in memory without printing until the ink tank is replaced. Print the fax stored in memory manually after replacing the ink tank. You can set the machine to print received faxes forcibly without storing them in memory, but a part of contents or all contents of the fax may not be printed.
"Print head is not installed. Install the print head." U051 "The type of print head is incorrect. Install the correct print head." U052	Click here to install the Print Head.

If you want to continue printing in this condition, you need to release the function for detecting the remaining ink level. Press and hold the Stop/Reset button for at least 5 seconds, and then release it. With this operation, releasing the function for detecting the remaining ink level is memorized. Please be advised that Canon shall not be liable for any machine malfunction or damage caused by refilled ink tanks.   Note If the function for detecting the remaining ink level is disabled, the ink tank in gray is displayed on the LCD when checking the current ink level.   Since printing in this condition may cause the contents of the fax to be lost, the machine stores received faxes in memory without printing until the ink tank is replaced. Print the fax stored in memory manually after replacing the ink tank. You can set the machine to print received faxes forcibly without storing them in memory, but a part of contents or all contents of the fax may not be printed.

Press and hold the Stop/Reset button for at least 5 seconds, and then release it. With this operation, releasing the function for detecting the remaining ink level is memorized. Please be advised that Canon shall not be liable for any malfunction or trouble which may be caused by continuation of printing under the ink out condition.   Note If the function for detecting the remaining ink level is disabled, the ink tank in gray is displayed on the LCD when checking the current ink level.   Since printing in this condition may cause the contents of the fax to be lost, the machine stores received faxes in memory without printing until the ink tank is replaced. Print the fax stored in memory manually after replacing the ink tank. You can set the machine to print received faxes forcibly without storing them in memory, but a part of contents or all contents of the fax may not be printed.
"There is no photo data."	There are no image data saved on the memory card that can be read by this machine. The machine may not recognize the file if the file name or the folder path contains certain characters. Use only alphanumeric characters. Photo data edited or processed on a computer must be printed from the computer.
"The card is currently write-enabled. Remove card and set to read-only mode before performing operation."	The Card Slot is set to USB enabled or LAN enabled. You cannot print when the Card Slot is set to USB enabled or LAN enabled. After writing on the memory card, set to Read-only mode again.

"Incompatible device detected. Remove the device."	A communication time out occurs if an operation takes too long or if it takes too much time to send data. This may cancel printing. In such cases, disconnect and reconnect the USB cable. When printing from a PictBridge compliant device, depending on the model or brand of your device, you may have to select a PictBridge compliant print mode on the device before connecting it to the machine. You may also have to turn on your device or select Play mode manually after connecting the device to the machine. Perform necessary operations before connecting your device referring to its instruction manual. If the error is still not resolved, check if you can print another photograph. Check your device connected to the machine. Only PictBridge compliant devices can be connected to the machine for direct printing. If a PictBridge compliant device is connected via a USB hub, remove the hub and connect it directly to the machine.
"An unsupported USB hub is connected. Remove the hub."	If a PictBridge compliant device is connected via a USB hub, remove the hub and connect it directly to the machine.

Remove the document page jammed in the ADF, then press the OK button. When the error is cleared, make sure that the document you are loading meets the machine's requirements before redoing the operation.
"Auto redial"	The machine is waiting to redial the recipient's number because the line was busy or the recipient did not answer when you tried to send a document. Wait for the machine to automatically redial the number. If you want to cancel automatic redialing, wait until the machine starts dialing the number, then press the Stop/Reset button. You can also delete the document from memory. See Auto redial to change the number of redial attempts.

"Try again in black & white."	The recipient's fax machine is not color-compatible. Press the Black button to resend the faxes. Alternatively, you can set Color TX to Send in black & white.
"Failed to connect."	The telephone line cable with a modular plug is not plugged in properly, or Dial tone detect is set to ON. Make sure that the cable is plugged in properly, and resend the fax after a while. If you still cannot send the fax, set Dial tone detect to OFF.
"Received in memory."	If the machine receives a fax under one of the following conditions, the machine will not be able to print the received fax and will store it in its memory. When the problem is resolved as described, the fax stored in memory is printed automatically. Ink has run out while receiving a fax: replace the ink tank. Note You can set to print the received fax forcibly even if an ink has run out. However, a part of contents or all contents of the fax may not be printed since the ink has run out. And also the contents of fax will not be stored in memory.

"Busy/no signal"	The telephone number you dialed is busy. Try dialing again after waiting for a moment. The fax number dialed was incorrect. Check the fax number and dial again. The recipient's fax machine did not respond (after all automatic redialing attempts). Contact the recipient and have him/her check the fax machine. For an overseas call, add pauses to the registered number. The recipient is not using a G3 machine. The machine cannot send or receive documents to/from the fax machine incompatible with G3 standard. Contact the recipient and ask him/her to check that the fax machine is G3 compatible. The touch tone/rotary pulse setting on your machine is incorrect. Set your machine to the setting that matches your telephone line.
"Memory is full."	The machine's memory is full because it has sent/received too many documents, or a detailed document. When sending faxes, divide them to resend. When receiving faxes, print or delete documents in the machine's memory, then ask the sender to resend the fax.
"The paper size is not correct. Change the page size you have set."	Paper of size other than A4, Letter, or Legal is loaded. When feeding from the Rear Tray, load A4, Letter, or Legal-sized paper. When feeding from the Front Tray, load A4 or Letter-sized paper.
