Cause:
Switching device or external buffer fault.
Solution:
Disconnect the switching device or external buffer and print with the printer directly connected to the comput-
er.
If you can then print normally, the fault is probably in the switching device or external buffer. Consult the
hardware manufacturer.
Cause:
USB hub fault.
Solution:
Disconnect the USB hub you are using and then directly connect the printer to the computer. If the printer
can print normally, the USB hub may not be operating properly.
Cause:
Printer is set to ECP mode.
Solution:
Disable ECP mode.
Open the Printer Properties dialogue box. Click on the Maintenance tab and then click on the Custom
Setting button. In the Custom Setting dialogue box, disable "Set printer to ECP mode" (if enabled) and click
on the Send button.
Cause:
Internal file or application software problem.
Solution:
Rebuild the document and print it again.
If there is no problem with the new document, the original file was probably faulty. If the same problem
recurs with the new file, contact a Canon service facility.
● Printout is faint or colours are wrong
Cause:
The print head nozzles in a BJ Cartridge are clogged or one of the inks has run out.
Solution:
Print a nozzle check pattern and check the status of the print head.
Cause:
Protective cap and tape have been re-attached to the BJ Cartridge.
Solution:
Remove the protective cap and tape. Install the BJ Cartridge again, and clean the print head.
Cause:
Not printing on correct side of the media
Solution:
Check that you load the media with the correct print side up.
For details about loading the media, refer to the Reference Guide on the Setup Software & Reference Guide
on the CD-ROM.
