9.3 Detection Jams
9.3.1 Jam Detection Outline
9.3.1.1 Overview
0019-5034
The machine is provided with several paper sensors at specified positions on the feed path to detect whether the paper exists or whether the paper is transported
normally or not.
When the machine determines that a jam has occurred based on the result of detection performed by each sensor, it stops print operation and displays an error mes-
sage indicating that a jam occurred on the control panel at the same time.
T-9-5
*: Specified time differs depending on the feed speed.
1/1 speed: approx. 2.0 sec
4/5 speed: approx. 2.5 sec
1/2 speed: approx. 4.0 sec
9.3.2 Delay Jams
9.3.2.1 Pickup Delay JAM
0019-5035
The machine performs the retry control, which executes the pickup operation up to three times, in order to retrieve the pickup delay jam caused by the pickup failure.
The machine determines that the pickup delay jam has occurred when the registration sensor (SR710) cannot detect the lead edge of the paper within a specified
period of time after the cassette pickup solenoid (SL5012) or manual feed pickup solenoid (SL5013) is turned ON for the third pickup operation.
T-9-6
9.3.2.2 Delivery Delay JAM
0019-5036
The machine determines that the delivery delay jam has occurred when the fixing delivery sensor (SR6005) cannot detect the lead edge of the paper even when
approximately 3.0 seconds elapsed after the registration sensor (SR710) detected the lead edge of the paper.
9.3.2.3 Duplexing Pickup Delay JAM
0019-5037
The machine determines that the duplexing pickup delay jam has occurred when the lead edge of the paper does not reach the registration sensor (SR710) within
approximately 2.0 seconds after the duplexing feed motor (M10) started feeding the paper placed in standby at the duplexing re-pickup position.
9.3.2.4 Duplexing Reverse Unit Delay JAM
0019-5038
The machine determines that the duplexing reverse unit delay jam has occurred when the reverse sensor (SR706) does not detect the absence of paper in the period
from the start of duplexing reverse to the detection of the duplexing pickup delay jam.
JAM code JAM type JAM condition
0104 Pickup delay JAM If the registration sensor (SR710) cannot detect the leading edge of the paper after 3 times retry within the specified
time from turning on of cassette pickup solenoid (SL5012) or manual pickup solenoid (SL5013).
0208 Pickup stationary JAM If the registration sensor (SR710) cannot detect the trailing edge of paper within approx. 3.2 sec after it detects the
leading edge of paper.
010c Delivery delay JAM If the fixing delivery sensor (SR6005) cannot detect the leading edge of paper within approx. 3.0 sec after the
registration sensor (SR710) detects the leading edge of paper.
0210 Delivery stationary JAM If the fixing delivery sensor (SR6005) continues to detect the paper after the theoretical time plus time for feeding paper
by 45 mm (approx. 3.1 sec) elapsed after the registration sensor (SR710) detects the leading edge of paper.
0214 Residual JAM If any of the registration sensor (SR710), paper loop sensor (SR6001), fixing delivery sensor (SR6005) or reverse sensor
(SR706) detects the paper during initial sequence.
1118 Door open JAM If the front cover sensor (SR720) detects that the front door is open during the paper feeding.
0221 Reverse assembly JAM If the paper length that is detected by the reverse sensor (SR706) is approx. 50 mm or more longer than the paper length
that is detected by the delivery sensor (SR715). (When the double-fed paper drops on the back of the machine.)
0228 Duplexing re-pickup
assembly JAM The machine determines the reverse re-pickup jam if the registration sensor (SR710) cannot detect the presence of paper
within the specified time* after the duplexing pickup starts.
