Printing pausing after each label printed? - Datamax DMX E4203 Printer

Hi, if is the vertical line, its the print head that need to be replaced,
try to clean the print head and try this to confirm:
turn printer off, press PAUSE button and at the same time, power on, don't release the button, please wait until printer LCD screen come on, then release button. It will print the PAUSE test and after few 3-4 prints, u can turn off and on again otherwise printer not ready to print your labels until u restart it. (pause test stops after 10-15 labels). this pause print just show how the print head is and if come with vertical lines, u will need to replace. other idea is (if u can) turn the bar code different position or on vertical way at label format. Thanks.

1. Turn the printer on and make sure that the LCD display reads 'ON LINE'.
2. Press the PAUSE key once. [The display will read 'PAUSE'.]
3. Press and hold the PAUSE key until four or five labels feed forward.
NOTE: On some models, pressing the pause key will change the LCD display to 'TRANSMISSIVE'. If this happens, repeat step 3.
4. Press the RESTART key. The printer will go back ON LINE.
5. Open the print head and reposition your labels, so that they are ready for printing. Close the print head.

Check to see if the pause light is on also. Make sure you are using the correct printer driver. (105se)

Printing the "PAUSE" test will print a nice black box that will show white lines or voids for any printhead elements that are not functioning. Turn the printer off, press and hold the PAUSE key while turning on the printer. After 5-6 seconds, let go of PAUSE and let the power up self test finish.

The test label will starting printing. To stop, press PAUSE. This is also usefull for seeing the "parallelism" of the printhead by looking at the lines that print at the begining of each label. Should be the same number of lines on the left as the on the right.

Easiest way to cancel the pattern is to cycle power.

Hope that helps !

Generally the ZM 400 can cope with printing at the lower speeds when printing barcoedes that are the same. You may get pauses if the barcodes are sequential numbers or are all different, then the data to be transfered to the printer cannot cannot keep up with the printer and pauses while it gets more data. We have found that if you can select in your labelling software to print the barcode as a graphic, then it speed up quite a lot. It is a matter of matching your print speed and quality to match your expectations, sometimes you will just have to put up with the pauses.

I Use driver from Nice Labels
http://www.nicelabel.com/downloads/nicedrivers/zebra seems to work fine

to test , press pause botton and turn on (press 5 sec.)
he print a "pause test".
check if print, if stop on ich gap and if come some lines across the print (if apear some lines, need new print head.) this step just pause wen print some labels, and then still print until turn off.
Turn off and turn on the printer to work normal.

To calibrate media, go on the setings to "sensor profile" and/or "run manual calibration, follow the steps. (dont forget to take the ribbon from the sensor.)
let the test run until finish.

what interface are you using? sounds like windows is sending the data to the printer as graphics which is much more intence then EPL hence the delay between each label.
