JAM DETECTION
C231/C237/C238 6-48 SM
Details
With the above change, the D-jam recovery flow has been changed as described
below.
NOTE: The following “Old Recovery Flow“ was not included in the original C238
Service Manual.
Old Recovery Flow (for versions before C2385114-H):
D-jam (master cut error) is indicated.
NOTE: This includes all D jams except for “Clamping the master”.
↓
Dispose of the jammed master in the plotter unit.
↓
When the plotter unit is pushed back in, the “B-jam” LED will light.
NOTE: This cannot be cleared by turning the main power off/on.
↓
Remove the wrapping master around the drum manually.
NOTE: When a master cut error occurs, the wrapping master length is not correct,
therefore it is necessary to remove the wrapping master manually.
↓
Machine returns to normal, however when the Print key is pressed,
the “M” LED lights, because the master has been removed. The
machine is able to print after the Start key is pressed.
New Recovery Flow (for version C2385114-H or newer):
D-jam (master cut error) is indicated.
NOTE: This includes all D jams except for “Clamping the master”.
↓
Dispose of the jammed master in the plotter unit.
↓
When the plotter unit is pushed back in, no error is displayed.
However when the Print key is pressed, the “M” LED light, and the
machine cannot print.
NOTE: The wrapping master length is not correct, therefore the
machine cannot print using the wrapping master.
↓
Machine returns to normal and is able to print after the Start key is pressed, as the
wrapping master is removed automatically. (It means “Master Eject”.)
NOTE: When SP2-12 (Drum master sensor) is off, the “B-jam” and “M” LEDs
cannot be cleared. The factory setting for this SP is on.
