Tacho Code Thursday – Code 39 – No paper
This code means the tachograph has detected that there is no paper in the printer during a printout or print request.
Code 39 is generated when the DTCO determines that the printer roll is missing or has been fully used. If this happens during an active printout, the print is interrupted and the previously printed section is automatically marked. If it occurs during a print request, the request is rejected.
Common causes include:
No printer paper inserted
All printer paper has been used
If Code 39 appears, the driver should check whether there is paper in the printer and insert a new roll if necessary.
If a new roll is inserted within one hour, the DTCO 4.1x will automatically continue the interrupted printout. The first two lines of the subsequent printout will show:
Line 1: Starting time of the original printout
Line 2: Counter of the successive prints
If the message continues to appear after inserting a new paper roll, the vehicle should be referred to an approved tachograph centre for further inspection.
