Problems and Solutions
Check to see if a print job has been canceled before completion
If you cancel a print job during printing, the data remaining in the printer may cause the
printer to produce strange characters. In this situation, restart the computer and the printer,
and start the print job again.
If you are using Windows, click Start, point to Programs, click BJ Printer, then click BJ
Printer Monitor and cancel the print job.
Determine if the problem exists only within a particular document
If unknown characters and letters are printed only for a specific document file, then the
problem may exist within that file, or the software application that you are using. In this
case, try typing the same text in a newly created file. If the new document prints normally
then the problem exists in the original document file. If the same problem occurs with the
new file, call the Canon Customer Care Center.
