BULLETIN NUMBER: 6645/6655-005 02/04/94
APPLICABLE MODEL: FT6645/6655
SUBJECT: SOFTWARE MODIFICATION
SYMPTOM:
1. - Registration Jam when copying on 4 hole punched paper
The jam occurs during continuous copy runs when the holes in the paper match the location of the
registration sensor.
2. - Process Control data initial setting does not function with the weekly timer activated
For customers who never turn the main switch "OFF", the auto process control does not work. After
approximately 150k copies, dark copies followed by copies with dirty background are produced.
3. - ADS does not function with the last original fed through the RDH
The 4th ID level is selected for the last original fed through the RDH. If multiple sets of copies are made,
only the last original of the first set is affected.
4. - SC742 (only with the RDH and Finisher system)
When the following conditions are met, the positioning roller [A] interrupts the paper feed out pawl [B],
resulting in an SC742 condition.
●
The previous customer selected the staple mode and did not clear the staple mode after job completion
●
Only one original is being copied
●
More than three copies are made (the problem occurs after feeding 4 or more copies)
NOTE: After the software modification,when the above conditions are met, the interval between copies
becomes longer to prevent the interruption between the positioning roller [A] and the paper feed out
pawl [B]. Only in this case, the CPU reduces the copy speed from 55cpm to 22.5cpm (A4/Letter
sideways). If the above three conditions are not met, the copy speed is 55cpm.
5. - Two roller marks on halftone image areas
When the following conditions are met, light lines appear on the latter half of the image as shown below.
●
Last paper fed from the duplex tray
●
There is halftone image area on the latter
half of the front side copy
