Troubleshooting Guide
If you selected [Clean now f], the shutter will make a noise, but no 
picture is taken (p.271).
 If you repeatedly turn the power switch < 1> / < 2> at a short 
interval, the < f> icon may not be displayed (p.40).
 Contents displayed on the screen vary depending on the printer. This 
instruction manual lists all the printing effects available (p.324).
 If any of the following shooting modes or functions is set, the camera 
cannot be connected to a printer. Cancel all the relevant settings, then 
reconnect the camera to the printer with an interface cable.
• or < G> in < 8> mode
• Multi Shot Noise Reduction
•[ 51: Wi-Fi/NFC ] set to [Enable]
 Install the EOS software (EOS DIGITAL Solution Disk CD-ROM) on 
the computer (p.404).
 If [51: Wi-Fi/NFC ] is set to [Enable], the camera cannot be connected 
to a computer. Set [Wi-Fi/NFC ] to [Disable ], then reconnect the 
camera to a computer with an interface cable.

screen instructions.
* If the error still persists, write down the error number and contact your 
nearest Canon Service Center.
Error Codes
NumberError Message and Solution
01
Communications between the camera and lens is faulty. Clean the 
lens contacts.
 Clean the electrical contacts on  the camera and lens, use a Canon 
lens, or remove and install the battery pack again (p.25, 26, 36).

Cause and countermeasures

Kit lenses* use a stepping motor that drives the focus lens. The motor 
controls the focus lens even during zooming.
* EF-S18-55mm f/3.5-5.6 IS STM, EF-S18-135mm f/3.5-5.6 IS STM, and EF-S55-250mm f/4-5.6 IS STM
1. When the camera is OFF The motor does not operate while the camera is OFF or when the 
camera is OFF due to the auto power off function. Therefore, users 
must be aware of the following points.
 Manual focusing is not possible.
 During zooming, inaccurate focusing may occur.
2. When the lens is in sleep mode If not operated for a certain period of time, this lens will enter sleep 
mode in order to save power, apart from the camera’s auto power off. 
To exit sleep mode, press the shutter button halfway.
In sleep mode, the motor will not operate even if the camera is ON. 
Therefore, users must be aware of the following points.
 Manual focusing is not possible.
 During zooming, inaccurate focusing may occur.
3. During initial reset When the camera is turned ON or when the camera is turned ON by 
pressing the shutter button halfway when the camera is OFF due to 
the auto power off function*
1, the lens performs an initial reset of the 
focus lens.
 Although the image in the viewfinder will appear out of focus 
during the initial reset, this is not a malfunction.
 Wait approx. 1 second*
2 until the initial reset has completed 
before shooting.
