Description
As a result of inspection, the following was found: When an A3-size original with sharp folds is set in the document feeder (DF), the machine detects it as
A4-size and scans the corresponding area. This is because the latter half of the original is folded and fails to come into contact with the document length
sensor flag on the DF, consequently preventing the length sensor from detecting the original as large size.
When scanning an original with sharp folds from the DF, remove the folds or place it on the copyboard glass. Moreover, the use of the Preview button on the
LCD before scanning enables you to check whether the full image of the original is scanned. Please explain these to your customer.

Description
When running a FAX transmission job consisting of 20 sheets of A4-size originals using the DADF-N1, the leading edge of an original stopped at the original
reading position, and then the machine hung up. This was because the read sensor (PI3) of the DADF chattered. This is for your information, but if the claws
of PI3 are not snapped securely into the mount, the sensor may chatter.
Field Remedy
When the symptom has occurred, snap the sensor into the mount again.

Description
When 178 destinations were registered in the one-touch buttons, 780 destinations in the address book, and 78 destinations as the forwarding settings, the LCD
on the control panel responded slowly. As the measure for this symptom, system software version 8.02 was released.
Field Remedy
When the symptom occurs, upgrade system software to version 8.02 or later.
14.2.5.2.2 DADF-N1: Stamp is not printed when sending FAX message because solenoid connector has poor connection

[ Case in the field ]
Field Remedy
In the field, a stamp was not printed when a document was scanned for FAX transmission. This was because the connector (J14) of the solenoid (SL2) had
poor connection. When the symptom has occurred, execute the following in service mode:
[FEEDER > FUNCTION > SL-CHK > enter "1" > OK > SL-ON > OK].
If the operating sound of the solenoid is not heard, reinsert the connector J14.

[ Case in the field ]
Description
In the field, the right lower door sheets were affixed askew to the inside of both upper ends of the right lower door that accompany the paper pick-up assembly
for the cassette 2, leading to 0105 Jam every time paper was fed from the cassette1.
Field Remedy
When a right lower door sheet is attached askew, re-fit it. If it is deteriorated, replace it with a new one.

14.2.6.2 0207 Jam Code: Because solenoid (SL1) does not work on account of defective delivery controller PCB

[ Case in the field ]
Description
In the field, the solenoid (SL1) of the 1st delivery flapper (FL2-1212) did not work, and as a result, a paper jam occurred at the delivery assembly when
making copies continuously. However, this symptom was solved by replacing the delivery controller PCB with a new one.
- 0207 Jam Code: Stationary jam at the fixing/delivery sensor (PS13).
Field Remedy
1. Service mode > COPIER > FUNCTION > PART-CHK > set [SL] to "7" (SL1 operation code) > OK > SL-ON > OK. This setting will make the machine
turn the SL1 ON and then OFF three times. On this occasion, check if the SL1 makes operating sound.
2. When executing [SL-ON] in service mode, if the indication on the LCD changes in the following order: START > ACTIVE > OK!, and no operating sound
occurs, check if the SL1 has electrical continuity.
3. If the SL1 have electrical continuity, re-insert the delivery controller PCB connectors, and then execute Step 1 again.
4. If the SL1 still makes no operating sound, replace the delivery controller PCB with a new one.
