Label gap The wasp printer will not recognize the gap between labels. Have tried everything WASP's technical supoort offered but to no avail. AutoGap will not work nor will setting the through/no through option.

you may =have to do a sensor calibration or it may just be that you need to adjust the sensor to the label.
2 types of labels GAP which i a space between the two labels ( they don't touch each other or knotch labels touch each other but there is a small open gap all the way to the Left of the Labels. If GAP move the Green sensor Bar to the middle of Labels.
If Knotched move to the LEft where the gap is, hit Feed button it should move one label at a time you may have to adjust slightly

Did you try turning it off and turning it back on

You need to run the Wasp software under an Administrative account or Right click the program Icon and select run as administrator (only need to do this 1 time, not over and over again). Once the program loads, set the label printer again by clicking file at the top left and selecting Setup Label Printer. Select your label printer. Now try printing the labels again.

Hello rlopez988,
Welcome, and thank you for using FixYa!
To answer your question: This is caused by another weaker component on the power supply board. This will typically point back to a resistor or capacitor going bad on the board.These components can be replaced piece by piece, and the entire circuit tested for future flaws. I normally would charge $120.00 with parts for this service.
Have a great day!

No, wrong company

You have to calibrate the printer. It thinks there is no ribbon (thermal mode) so it's not winding the ribbon up. The instructions are on page 11 of the manual -
4.2 Ribbon Sensor Calibration
Note: Please make sure the ribbon is properly installed before doing this calibration.
Please follow the steps below to calibrate the ribbon sensor.
1. Turn the printer power off.
2. Press and hold the FEED button then turn on the printer.
3. The LED will turn orange then blink red 5 times. Release after the first red blink and before the 5rd.
4. If the ribbon is properly installed the light will turn green. If it is not it will turn red and blink.

Remove the ribbon. On each side of the head is a small yellow tab. Push one side in then drop that side of the head and pull the other side out. Disconnect the connector on the back.

Firstly make sure your using the correct drive ZM400 rather than Z4M. if you are using the applications driver make sure of headers and footers sizes and the print area is set correctly. If your using odd sized lables download some new drivers from the Nice Label website, they are far more adjustable that the standard Zebra drivers.

I am surprised that you are using that sequence of buttons to solve this problem. I am pretty sure that they want you to go into the "Media Sensor Calibration" setup in the config menu. It is a bit more complicated than what you have described. I also believe that the size of the gap on two of your labels might be out of tolerance (they are usually 1/8" gaps between the labels). The black marks are a problem for the transmissive sensors. You may need to move the transmissive media gap sensor (remember it has two parts: upper and lower). I would usually setup mine for a place beyond the black mark so that you are looking at just the white paper.

To start out:
1. Load the backing of a 6" strip of media (no label attached).
2. Remove a ribbon (if you usually use one).
3. Close the printhead.
4. Press SETUP/EXIT and then NEXT/SAVE until "Media and Ribbon Calibrate" appears.
5. Press "+" to start the calibration procedure. You should see the "Load Backing" in the LCD Display. You already have the backing loaded so continue to the next step.
6. Press "+" to answer the message and the next screen should say, "Remove Ribbon". You have also removed the ribbon.
7. Press the "+" to continue. You should see the screen say, "Calibrating Please Wait". After the sensors are setup by the machine a new screen should appear, "Reload All".
8. Open the printhead, and move the labels until they are loaded correctly to print. Smooth out the ribbon and load it correctly.
9. Withe media and ribbon now loaded, press "+" to continue and the machine should say, "Media and Ribbon Calibrate".
10. Press the Setup/Exit button once. It should say, "Save Changes Permanent". Press Next/Save to finish the process.
11. Do a normal calibration of your stock and print a label.

You are done. The machine will run for the labels you have setup the sensors for. Unfortunately, you must do this for each of the media types. To automate this, you could run a Configuration listing, capture the settings you just created for each type of label. Take these to a programmer to have them send the setup to the machine before the job. This is beyond the scope of this type support to really help you.
