8.3.3 Stationary Jams

8.3.3.1 Pickup Stationary JAM

imageCLASS MF9170c / imageCLASS MF9150c / imageCLASS MF8450c
The machine determines that the pickup stationary jam has occurred when the registration sensor (SR710) cannot detect the trailing edge of the paper even when
approximately 3.2 seconds elapsed after it detected the lead edge of the paper.

8.3.3.2 Delivery Stationary JAM

imageCLASS MF9170c / imageCLASS MF9150c / imageCLASS MF8450c
The machine detects the delivery stationary jam after determining that the wrapping jam did not occur.
The machine determines that the delivery stationary jam has occurred when the fixing delivery sensor (SR6005) detects the presence of paper even when the time
equivalent to theoretical time plus 45 mm (approximately 3.1 seconds) after the registration sensor (SR710) detects the trailing edge of the paper.

8.3.4 Other Jams

8.3.4.1 Wrapping JAM

imageCLASS MF9170c / imageCLASS MF9150c / imageCLASS MF8450c
The machine detects the wrapping jam after determining that the delivery delay jam did not occur.
The machine determines that the wrapping jam has occurred when the fixing delivery sensor (SR6005) detects the absence of paper before the time equivalent to
the paper length detected by the registration sensor (SR710) minus 50 mm (approximately 1.9 seconds) elapses after the sensor detects the lead edge of the paper.

8.3.4.2 Residual JAM

imageCLASS MF9170c / imageCLASS MF9150c / imageCLASS MF8450c
The machine determines that the residual jam has occurred when any of the registration sensor (SR710), paper loop sensor (SR6001), fixing delivery sensor
(SR6005), or reverse sensor (SR706) detects the paper at the initial sequence.

8.3.4.3 Door Open JAM

imageCLASS MF9170c / imageCLASS MF9150c / imageCLASS MF8450c
The machine determines that the door open jam has occurred when the front cover sensor (SR720) detects that the front cover is opened during paper feeding.

8.3.4.4 Automatic Delivery Function

imageCLASS MF9170c / imageCLASS MF9150c / imageCLASS MF8450c
When the registration sensor (SR710) detects the presence of paper after detecting the absence of paper at the initial sequence after the power was turned on or the
front cover was closed, the machine drives the motors and solenoids in the feeding system and delivers the residual paper automatically.
