Hello my Toshiba B-Sa4TM printer states paper jam but there isn't anything jammed? i don't have a clue how to calibrate the sensors any ideas??

You may have a mis alignement of the detecting cells.
The arrow on the top part of the cells should be on the round hole on the bottom part. (Green plastic mecanism)

There is usually a setting in your label software or printer driver that lets you choose between thermal transfer printing or direct thermal printing. Make sure your setting is on direct thermal.

Ribbon Error

According to the user's manual this message indicates a problem with the ribbon sensor. As a test, set the unit for thermal direct printing and attempt to print a barcode. You will not see the code if yoiu are expecting thermal transfer, but the paper/label should feed like it is printing. That will indicate that the printer is functioning. At this point, the sensor needs to be replaced.

Hope this helps,

Paper jam error message

This problem is a detection problem, due to a bad sensor selection or incorrect label size.

If the labels are white labels with a separation between each, select TRANSMISSIVE. If the labels are preprinted, select the TRANSMISSIVE PREPRINTED LABELS and set the threshold doing this.

With the printer in ONLINE, press PAUSE once, the message PAUSE appears in the display, press and hold on the PAUSE key, TRANSMISSIVE is displayed, release the key and press PAUSE until labels starts to feed, let feed some labels (5 or 6) and release the key. Press Restart and start to print.

Paper jam on this printer have several causes:
- The size of the label is not correct (The legth mainly)
- The type of Sensor is not correct.
Transmissive or reflective.
- You are using preprinted labels which affects the detection.
To solve this you have to callibrate the sensors for the preprints. Check your manual or contact us.
- there mays not enough contrast between the liner and the labels. You must check the sensors
- Check if the sensors are correctly aligned. You may misaligne the top and the bottom sensors
