Canon LBP7660Cdn Manual page 324

The body of an HTML e-mail is printed as a plain text message.
E-mail text is printed with its mail header information.
If the number of characters in one text line (without a line break) in an e-mail exceeds 998, an automatic linefeed is
performed. Because of this, the text in the next line may not be printed properly.
When the toner cartridge is nearing the end of its lifetime, reception of e-mails becomes impossible.
