3.3 PRINT HEAD FAN
3.3 PRINT HEAD FAN
When printing a high print rate pattern in batch mode, the print head will overheat, causing the print head
protection circuit to be activated. This will stop printing with displaying the error message “EXCESS
HEAD TEMP”. (e.g. When the printer prints an entire black pattern at a speed of 6"/sec., it may stop
printing after about a 6-minute operation.)
1) Unplug the power cord.
2) Remove the side panel (L) from the printer.
3) Attach the print head fan to the print head frame with the enclosed two SM-3x12 screws.
4) Connect the print head fan to the head fan harness and fix it with the cable clip.
NOTE:
The harnesses and cable clips should be installed so they do not obstruct removal and
installation of the ribbon modules.
5) Install the side panel (L) to the printer.
