Missing lines 105SE

There are several reasons why this could be happening. If the computer accessing the printer changed then I assume the new computer was recently set up with software to send print information to the printer. I would start with simple calibration and move from there. Zebra Technologies 105SL Printer Calibrating the Printer With Video

Missing elements in print head, replace print head.

the drum is light sensitive and if one side was exposed to sunlight for as little as 20 seconds could have that effect , it is at best a shot in the dark (no pun intended)

Label position may be off. Power on while pressing the cancel key for 10 seconds. This should print a configuration label. Use large label for this. Check the parameters, specifically top position and tear off position. The default is 0. You might also check the main drive belt for stretch or missing teeth. You need a user manual for that printer because there is no lcd panel. It is not user friendly without manual.

Sounds like there are some elements worn off of the printhead causing some of the bars to not be printed. To test, create a label that prints a thick black line or solid black box across the width of the label (assuming a 4" label). Any vertical white lines that show indicate elements that are not functioning.
You could also put one label above the other, lining up the barcodes and you'll probably see bars that are missing from the label that won's scan.
The only ways to correct the problem are to install a new printhead or move the barcode field on the label so that the missing elements fall in the spaces between the bars.

Hope that helps !

It sounds as if the print head needs cleaning. Follow the instructions in section 10.1 of your manuaI If you don't have a manual you can get it here - http://www.toshibaprinters.com/technical_information/technical%20info.htm. If the cleaning doesn't work you will need to replace the head.

Clean your platen roller. It's the white rubber roller (that turns and pulls your labels through your printer) located under your printhead. When this gets slick it causes your labels to slip while printing.
You should use rubbing alcohol to clean it. Your computer guys may also have some cleaning wipes in a foil packet that you can use.

Have you tried cleaning the sensor? It is underneath the labels oppoistethe print head.

The label sensor is not detecting the gap between the labels.

Make sure the labels are loaded all the way to the left (as viewed fron the front) and make sure the label guide (near the back of the printer) is set to keep the labels from wandering away fromt he sensor.

There is a pair of infrared emiter and detector located above and below the label path. As label pass between, these measure the leading and trailing edges of each label.

If you haven't already done so, calibrate the printer, by using the "Online", "Calibrate", "Online" buttons. If the "Feed" button doesn't feed just one label, you'll need to adjust the label gap sensors. This can be a bit trick if your labels are very narrow.

There should be a small pcb on a shaft under the label path. Note its current location, then slide it left or right to get a better signal, and try the feed button again. On my Zebras, the sensor is not in the middle of the PCB. Look for a small metal "can" on the PCB and center that.

The upper sensor is more difficult to adjust, but if you manage to spot a very small PCB above the labels, it will be easier to line these up.


If the labels are extemely

Try cleaning the thermal printhead. Zebra makes thermal printhead cleaners or you can use a qtip and some isopropyl alcohol.

Make sure the printer is turned off before doing this.
