The printer's front cover is open. To resume printing, close
the cover.
The print job was too complex for available memory.
Discard the last printed page, and try one or more of the
following:
❏ Close other applications while printing this job.
❏ Print the job in smaller sections.
❏ Try reprinting the job with a lower resolution, such as
300 dpi.
❏ Reformat the most complicated pages in the print job
to reduce graphics and other complex formatting.
The network adapter or printer power is not on, or the
printer is not connected.

cable has been disconnected or the port connection
destination has been changed during printing.
The Canon Advanced Printing Technology has detected an
internal problem in the LBP-810 engine.
