Detecting Errors (E805) - Canon GP335 Service Manual

C. Detecting Errors (E805)
Each fan of the machine is equipped with an error detection mechanism.
If any fan suffers a deviation in rotation or fails to rotate at a specific speed, the machine will
indicate an error code unique to that fan on the control panel.
The machine uses detail codes to isolate as many as 16 fans; if 'E805' is indicated, be sure to
check the detail code in service mode.

In addition, each fan has its own direction (current of air); be sure to orient them correctly
whenever they must be disassembled/assembled or replaced.
