| JAM type | Misfeed at PK JAM | ||
| JAM code | 72-43 | ||
| JAM detection timing | <When FS-536+PK-520 or FS-536SD+PK-520 is installed> The punch position sensor (PS2) is not turned ON (unblocked) after a lapse of a given time after the punch drive motor (M1) starts rotating. | ||
| <When FS-537+PK-523 or FS-537SDPK-523 is installed> The punch position sensor (PS301) is not turned ON (unblocked) after a lapse of a given time after the punch drive motor (M301) starts rotating. | |||
| – | <When FS-537+PK-523 or FS-537SD+PK-523 is installed> Paper jam of a sheet of paper left at the PK section results, when the main power switch is turned ON, and the paper is detected by the paper size detect board (PSDTB). | ||

Residual paper jam (When FS-537+PK-523 or FS-537SD+PK-523 is installed)
| Step | Action | Control signal | Location of electrical component |
|---|---|---|---|
| 1 | Initial check items | – | – |
| 2 | Adjust the sensitivity (light intensity) by selecting [Finisher] -> [FS-FN adjustment] -> [Punch F. Sensor Intensity Adj.]. After adjustment, open and then close the front door, and check if the residual paper jam indication disappears. To turn off the main power switch, wait for more than 10 seconds until the residual paper jam indication disappears. | – | – |
