Troubleshooting. Feed jam (error code 380)
Jam occurs immediately after the power is turned on.
Check item | Checking method | Action |
---|---|---|
Check condition of the paper running path | ||
Paper running path of the front unit | Open the front cover check if paper is not jammed in the paper running path. | Remove the jammed paper. |
Check condition of the mechanical parts | ||
Hopping sensor, IN sensor and WR sensor lever check | Check the sensor lever shapes and operations for any problem. | Replace the sensor lever(s) with proper one(s). |
Check condition of electrical parts | ||
Check the detection condition of the sensor signal | Confirm that the sensor signals are normally detected by using the Maintenance Menu SWITCH SCAN function | Replace the CU/PU board or sensor or cable. |
Hopping sensor, IN sensor and WR sensor output level check | Check the following signals by using the CU/ PU board HPSNS and RGSNS connector : HPSNS 2pin: Hopping sensor RGSNS 5pin: IN sensor RGSNS 2pin: WR sensor Confirm that the above signal levels change when the sensor lever is operated. |
Replace the appropriate sensor(s). |
Jam occurs immediately after the paper feed is started.
Check item | Checking method | Action |
---|---|---|
Check condition of the paper running path | ||
Paper running path of the front unit | Check if paper is jammed or not in the paper running path. | Remove the jammed paper. |
Check condition of the mechanical parts | ||
Hopping sensor, IN sensor and WR sensor lever check | Check the sensor lever shapes and operations for any problem | Replace the sensor lever(s) with proper one(s). |
Motor operation check | ||
Paper feed motor | Confirm that the paper feed motor works normally by using the Motor & Clutch Test of the self-diagnostic mode. | Replace the CU/ PU board or the feed motor. |
Paper feed motor driver | Pull out the CU/PU board HOP connector, and check the following at the side of the connector: Between 1pin – FG: Several MΩ Between 2pin – FG: Several MΩ Between 3pin – FG: Several MΩ Between 4pin – FG: Several MΩ |
Replace the CU/PU board. |
Clutch operation check | ||
Feed clutch and regist clutch | Confirm that the feed clutch and regist clutch works normally by using the Motor & Clutch Test of the self-diagnostic mode. Pull out the cassette for the rollers to be seen, and check operation. | Replace the CU/ PU board or the feed clutch or regist clutch. |
Check the system connection | ||
Paper feed motor drive cable | Check the connection condition of the cable. Check if the connector is connected in the half-way only or not, and check if the connector is inserted in a slanted angle or not. Check also that cables are assembled without any abnormality. | Replace the cable with the good cable that normalizes the connection condition. |
Pull out the CU/PU board HOP connector, nd check the following at the side of the connector: Between 1pin – FG: Do not short-circuit Between 2pin – FG: Do not short-circuit Between 3pin – FG: Do not short-circuit Between 4pin – FG: Do not short-circuit |
Replace the cable with the good cable that normalizes the connection condition. | |
Feed clutch cable | Check the connection condition of the cable. Check if the connector is connected in the half-way only or not, and check if the connector is inserted in a slanted angle or not. |
Normalizes the connection condition. Replace the clutch. |
Feed clutch | Pull out the CU/PU board HOC connector, and check the following at the side of the connector. Between 1pin – FG: Do not short-circuit Between 1pin – 2pin: About 240Ω |
Replace the clutch and properly assemble appropriate parts. |
Regist clutch | Pull out the CU/PU board REC connector, and check the following at the side of the connector. Between 1pin – FG: Do not short-circuit Between 1pin – 2pin: About 240Ω |
Replace the clutch and properly assemble appropriate parts. |
Paper feed motor | Pull out the CU/PU board HOP connector, and check the following at the side of the connector. Between 1pin – 2pin: 3.4Ω or 5Ω Between 3pin – 4pin: 3.4Ω or 5Ω |
Replace the Paper feed motor. |
