       The Device is Not Detected  
      Check the following.

NOTE
  • If the device is not detected even after you have confirmed the following, restart the mobile terminal. The device may be detected.
  • If the device is still not discovered, consult your network administrator about the network environment.

Canon Device
Does the device you are using support Canon Mobile Printing? (→ "About Supported Printers and Multi-function Devices")
PIXMA Series/SELPHY Series/MAXIFY Series do not support Canon Mobile Printing. Use PIXMA/MAXIFY Printing Solutions or Canon Easy-PhotoPrint.

Search Method
(→ "Selecting/Detecting the Device")
Can you discover the device from [Select Printer] - [Manual Search]?
Depending on the network environment to which the mobile terminal is connected, the device might not be discovered by [Select Printer] - [Auto Search]. If this happens, you need to do a manual search.

Can you discover the device when searching for devices manually by entering the FQDN (format including host name, subdomain name, and domain name)?
If the host name is "device01", the subdomain name is "aaa", and the domain name is "bbb.com":
device01.aaa.bbb.com

Network Settings of the Mobile Terminal
  • Is [Settings] - [Wi-Fi] enabled on your mobile terminal?
  • Is an HTTP proxy set on your mobile terminal?
  • If an HTTP proxy is set in the network settings of the mobile terminal, depending on the device you may not be able to connect correctly from this app. If this happens, contact your network administrator.

Network Settings of the Canon Device
  • Is the SNMPv1 setting set to [On]?
  • Is the LPD (LPR) print setting set to [On]?
  • Is the gateway address set correctly?
  • Is the subnet mask set correctly?
 
       
       Searching for a Device Takes a Long Time  
      When you discover devices by the [Select Printer] screen > [Auto Search], detected devices are listed as they are discovered. The device searching process normally takes about 10 seconds.

If you enter an IP address of an invalid DNS server in the Wi-Fi settings of the mobile terminal, a timeout occurs during the host name acquisition process, therefore the device searching process may take some time.
 
       
       Maximum file size that can be previewed and printed  
      You can preview and print files of up to 10 MB.
If a file is too large, an error message may be displayed due to insufficient memory, or this app will quit.

NOTE
  • Depending on the data content, such as images with an extremely large number of pixels, you may not be able to print files of less than 10MB.
  • You can upload files of up to 20 MB to the Data Conversion Service. (→ "Printing Microsoft Office Files")
 
       
       How to print the text of emails  
      Email text printing is not supported.
You can print an email using the following method.

Save the email screen as a screenshot and print:
Pressing and holding both the power button and the sound reduction button of the mobile terminal saves screenshot image data. You can print the saved screenshot with the photo album function of this app. (→ "Printing Images")
 
       
       Some PDFs cannot be previewed  
      If an encryption level is used that is not supported by the iOS, such as 256-bit encryption or encryption by a digital certificate, you cannot print a PDF with Canon Mobile Printing.

In such a case, a message saying that the file cannot be opened is displayed. To print with Canon Mobile Printing, change the encryption level of the PDF on a computer.
 
       
       A document is not printed correctly  
      If you activate Canon Mobile Printing from other apps and print documents other than PDF files, Canon Mobile Printing may not start correctly, and the files may not be able to be previewed or printed correctly.

When printing a Microsoft Office file, by performing layout correction using the Data Conversion Service, you can print the file with its original layout. (→ "Printing Microsoft Office Files")

Or, convert the file to PDF and print it. If you are using special fonts, enable the setting for embedding fonts when converting to PDF.
 
       
       Data is not printed according to the print settings  
      If you set functions that are not supported by the device you are using in the [Print Settings] screen, the settings will not be applied.

[Job] - [Store]
For devices that do not support user inbox storing, normal printing is executed.

[Job] - [Secure Print]
For devices that do not support the Secure Print function, normal printing is executed.

[Dept. ID Mgt.] - ON
For devices that do not support the Department ID Management function, normal printing is executed.

NOTE
For using the Department ID Management function, enabling the Department ID Management function at the device is necessary. For details, refer to the manuals provided with the device.

[Output Size]
If you specify a paper size that is not supported by the device, the print job is printed on another paper size or a paper confirmation message is displayed on the control panel of the device.

[Color] - [Color]
For devices that do not support color printing, the settings are not applied and the print job is printed in black and white.

[2-sided] - ON
For devices that do not support 2-sided printing, the settings are not applied and the print data is printed on one side of the paper.

[Staple] - ON
For devices that do not support stapling, the settings are not applied and the print data is printed without being stapled.
Even if you are using a device with a finisher that supports stapling attached, for a page size other than Letter or A4, the print job may be output without stapling.

NOTE
  • The settings that are displayed differ for each device.
  • When the device supports acquisition of configuration information, if you use the [Select Printer] > [Printer Details] > [Update Printer Information] function, you can display the items corresponding to the functions of the device in the [Print Settings] screen. If the configuration information of the device cannot be acquired, all items will be displayed in the [Print Settings] screen. (→ "Confirming Device Information")
 
       
       There is an Incoming Telephone Call While Using This App  
      Incoming telephone calls do not present a problem during printing.

Because mobile terminal OSes support multi-tasking, print processing continues for the enabled period even if this app is not being displayed.

If the enabled period is exceeded, the job will be canceled.
 
       
       How to Confirm the IP Address of the Device  
      You can confirm the IP address from the network settings screen of the device.
For details, refer to the manuals provided with the device.

NOTE
In the case of a device for which manager settings have been configured, you need to enter a password. For details, refer to the manuals that are provided with the device or contact your system administrator.
 
       
       The device does not respond  
     

Check the following:

  • Is the device turned on?
  • Is the device's LPD (LPR) print setting set to [On]?
  • Is the device online?

NOTE
The confirmation method differs for each model. For details, refer to the manuals provided with the device.
 
       
       Black and white data is counted as color data  
      Some devices may count black and white data as color data when printing from Canon Mobile Printing.

To have black and white data counted as black and white data, print using one of the following procedures.

Change the print settings:
Tap Print Settings in the preview screen when executing printing, and select [Color] - [B&W].

Print without using the [Photo Albums] function:
If you read an image into [Photo Albums] via iTunes on a computer, the colors may be adjusted and converted into color data in iTunes.

If this happens, re-read the image into a file management app other than [Photo Albums], and after opening the image, tap [M Printing] in the share menu to recall this app and print.
 
       
       Excel sheets that are not selected are printed  
      When you print Microsoft Excel files (xls and xlsx) that comprise multiple sheets, you can select which sheets to print in the sheet selection screen.

However, if you use the Data Conversion Service, all sheets are subject to printing even if you select a sheet or sheets in this procedure. After the Data Conversion Service has finished, delete unwanted pages in the [Preview] screen.
 
       
       What Port Numbers to Allow in a Firewall  
      Canon Mobile Printing uses the following port numbers.
443 TCP for communication with the Data Conversion Service
515
9100
TCP for print jobs
161 UDP for searches
47545 UDP for acquiring device information
9013 TCP for acquiring MF series device information
 
       
       Printing documents takes time  
      When using the Data Conversion Service for printing a Microsoft Office file, uploading and downloading data may take several minutes depending on the content of the data to be printed and the communication environment you are using.

NOTE
  • If you can tap [Print] in the [Preview] screen before all rendering by the Data Conversion Service is complete, printing is started. Because the rendering and printing processes are being executed in parallel, the processing time is shortened. However, If you specify the print range in an Excel file (xls and xlsx), you cannot do so until all the data has finished being converted.
  • Files that have simple layouts and text may only suffer minimal layout errors if you do not use the Data Conversion Service. If there appear to be no problems when you check the preview, tapping [Print] without tapping [Image Correction] will print the file with the mobile terminal OS performing the rendering process. In this case, although the processing time is shortened compared to using the Data Conversion Service, there is a possibility of the file being printed with an incorrect layout.
 
       
       How to Check Data Conversion Service Maintenance Information  
      The Data Conversion Service, which can correct the layouts of Microsoft Office files when printing, performs a rendering process by communicating with a server over the Internet. This service is sometimes temporarily unavailable due to maintenance.

To check maintenance information, tap [] - [Maintenance Information] in the Canon Mobile Printing main screen.
 
       
       A Time Out Error is Displayed After Printing Starts  
      Depending on the content of the print data, the time from the start of printing in this app and print output may take some minutes.

Because mobile terminal OSes support multi-tasking, print processing continues for the enabled period even if this app is not being displayed.

If the enabled period is exceeded, the job will be canceled.
 
       
       An Inappropriate Warning Message is Displayed  
      If you use this app when the usable storage capacity of the mobile terminal is approaching 0, an inappropriate warning message may be displayed.

If this happens, use the mobile terminal after deleting unnecessary data.
 
       
       Printing Method from iWork  
      As well as printing files in iWork format by starting this app from iWork for iOS 2.0 or later (Pages, Numbers, Keynote) and printing files, you can print using the following method.

NOTE
  • For information about how to operate iWork 2.0 or later, refer to the iWork help.
  • If you print using the following method, there may be cases where the print job is not output with completely the same layout as the original.

Convert to PDF Format with iWork and Print
If you select "PDF" for [Format] when opening the file in iWork 2.0 or later (Pages, Numbers, Keynote) and start this app, you can print with the original layout.

Printing Microsoft Office Files
You can open Microsoft Office files (doc, docx, xls, xlsx, ppt, pptx) in iWork 2.0 or later. If you select "PDF" for [Format] when starting this app, you can print the almost the same layout as the original.

NOTE
If you want to print documents with a layout that is more faithful to the original, open the file with Microsoft Office rather than iWork, start this app, and use Data Conversion Service. (→ "Printing Microsoft Office Files")
 
       
       PDF Direct Printing Restrictions of Use  
      For PDF direct printing compatible devices*, send the PDF file directly to the device to be printed.
* [] is shown in the [Select Printer] screen for PDF direct printing compatible devices. (→ "Confirming Device Information")

Take care of the following when doing so.
  • The print preview displayed in the [Preview] screen and the actual print result may differ.
  • If you set [Preview] screen > [Print Settings] screen > [Staple], the document may be stapled at different positions to those indicated in the thumbnail image in the [Preview] screen.
  • If an error occurs when printing a PDF file in which a password has been set, an error message is not displayed on the mobile terminal. An error message is displayed on the control panel of the device.
