When FS-539 or FS-539SD is installed
Contents
| JAM type | Misfeed at FS transport section (When FS-539 or FS-539SD is installed) | |
| JAM code | 72-18 | |
| JAM detection timing | 72-18: The main tray exit sensor (PS16) is not turned ON even after the lapse of a given period of time after the leading edge of the paper has turned ON the FNS entrance sensor (PS4). While the buffer is controlled, the main tray exit sensor (PS16) is not tuned ON even after the lapse of a given period of time after the reverse rotation drive is started. | |
| Misfeed processing location | Front door | |
| Relevant parts | -FNS entry transport motor (M2) -FNS entrance sensor (PS4) -Main tray exit sensor (PS16) -FS control board (FSCB) |

When FS-540 or FS-540SD is installed
Contents
| JAM type | Misfeed at FS transport section (When FS-540 or FS-540SD is installed) | |
| JAM code | 72-18 | |
| JAM detection timing | 72-18: The main tray exit sensor (PS37) is not turned ON even after the set period of time has elapsed after the FNS middle sensor (PS36) is turned ON by the paper. While the buffer is controlled, the main tray exit sensor (PS37) is not tuned ON even after the lapse of a given period of time after the reverse rotation drive is started. | |
