[ Inspected by Canon Inc. ]
Description
The error code "E820-0003" (fan error) was indicated when the primary corona assembly[1] was mounted. This was because the fixture [2] of the assembly
was not fixed (with the screw [3]) at the bottom-left within its movable range.
Cause
Because of the ill-positioned fixture, the primary corona assembly failed to go as far as it could and had poor contact, causing noise. This noise caused the
error code.
Field Remedy
When the error code "E820-0003" was indicated after mounting the primary corona assembly during service work, following the procedure below and check
to see if the fixture of the assembly is installed correctly.
1. Push the primary corona assembly with fingers. If the assembly moves with click (i.e., if there is play), suspect that the assembly is not mounted correctly.
2. Using a screw, fix the fixture [2] at the bottom-left within its movable range.

[ Inspected by Canon Inc. ]
Description
When running a copy job to print a black-and-white image on 60 sheets of 13x19-size plain paper, the message "Adjusting gradation. Please wait a moment."
and then the error code E842-0009" was indicated after all the 60 copies had been output.
- E842-0009 can be displayed when the external heat roller is detected as being in contact with the dormant fixing roller for 300msec continuously (an error
in pressing the external heat roller).
Cause
During last rotation performed for the time of a continuous black-and-white job, the fixing roller stopped earlier than the specified timing, letting this machine
falsely detect E842-0009.
Field Remedy
For the purpose of preventing false detection of E842-0009, the DC controller software was upgraded to Ver. 12.03. When the same symptom occurs, check
the version of the DC controller software; if it is earlier than Ver. 12.03, upgrade the software to Ver. 12.03 or later, and then make copiers.
