Delivery Assembly - Canon imageRUNNER ADVANCE C255 Series Service Manual

Stop registration control stops the Pre-registration Roller. Paper fed by the Pre-registration Roller after being picked up from the
cassette or Multi-purpose Tray generates an arch due to being pushed against the Registration Roller which has been stopped.
In order to align the image on the ITB with the paper at a specified timing, this control stops paper feed with the paper arched,
aligns the image on the ITB with the paper at the specified timing, and then resumes paper feed.
■ Size Mismatch Detection Control
If the actual paper differs from the specified paper in length, this machine judges that a jam has occurred, and the operation is
stopped without delivering the paper. (Jam code: 0D91)
Paper size mismatches are judged on the basis of the following criteria.
• The difference between the paper length detected by the Cassette 1 Size Switch and the paper length calculated on the
basis of the time it took the paper to get past the Pre-Registration Sensor (PS04) is 20 mm or more.
• The difference between the paper length specified by the user for the Multi-purpose Tray and the paper length calculated on
the basis of the time it took the paper to get past the Pre-Registration Sensor (PS04) is 20 mm or more.
