1. have entered in the template If the label height specified in the template is slightly greater than the actual height of the label then the sensor will be late looking for the gap and possibly miss every other label Occasional label is blank Q My printer is producing occasional blank labels when I print die cuts How can I prevent this A Check the following 1 Calibration of the printer s gap sensor The gap sensor is an optical device When you change label stock recalibration can be necessary because backing paper varies slightly in optical density from one roll to the next 2 Try reducing the gap size setting in the software by 1mm BarTender video Gap setting 3 Check that the labels are not physically damaged or flawed Check that none are missing from the roll and if one is missing check that it is not stuck inside the printer somewhere If the blanks are random there could be a marginal setting causing the trouble In other words if the label height you have entered in the template is exactly equal to the physical height of the label plus the vertical gap relating to it the printer might only see the passing of some labels When designing a template if you are unable to make precision measurements it is usually best to round numbers downwards For example if the gap seems very slightly under 3mm then entering 2mm in the template would be fine 4 Maybe your label stock is of the black line type but the template is2. one side of your label is not printing properly try increasing the head pressure both screws equally at first to about 4 See user manual and illustration below Note that 300 micron stickin labels can be wider than the print head and so must be inserted in the printer with the non printable portion on right hand side LabelStation Industrial special considerations After years of heavy use it might become necessary to make general adjustments to the entire mechanism See following picture Z axis balancing screw Print head pressure screws Azimuth burn line adjustment The Z axis balancing screw tilt adjustment equalises the two head pressure springs when they are set to the same number The print head pressure screws allow the left and right pressure to be adjusted independently The burn line screws are used to align the print head to the top of the platen roller arc and should be adjusted only by a competent technician If adjusting the print head pressure screws does not improve print quality and it is observed that when the pressure screws are set equally the print head pressure remains unequal adjust the Z axis screw If the print head pressure is satisfactory but the print quality remains poor then probably the print head is either dirty or worn out Q Why are my labels generally poor now that I have started a new roll A Check that your labels and ribbon are not past their shelf life or of poor quality gene

4. Print Quality amp Completeness Please note there is much commonality between the different models of LabelStation and therefore it is advisable to read the comments on other models if you cannot find a diagnosis relating to your own All labels are blank Q My printer goes through the motions of printing and I can even hear the print head buzzing but nothing is printed What can do A Check that the ribbon is loaded correctly waxy side down Videos Pro 200 amp Pro 300 Industrial models All labels are blank Q My printer goes through the motions of printing but not everything sometimes nothing is printed What causes this A On the label template check that no boundary box which appears around a label object when it is selected overhangs the label A small amount of overhang is permissible but if the object which does not print contains characters from a printer font try changing to a Windows font Every other label is blank Q Alternate labels are blank How can correct this A Make sure the label height depth you have entered in the template of your label corresponds to the physical height of the label Likewise make sure that the vertical gap has been measured correctly Where there is any doubt enter a slightly lower figure BarTender videos Page setup Gap setting It is helpful to know that the gap sensor only begins looking for the gap when the gap is expected based on the label dimensions you

8. s database use only but can be confusing when printing non database driven labels Blotchy bar code Q lam using a Pro 300 and my barcode printed blotchy after rotated it 90 degrees Why A Try using a very low print density aka temperature darkness with a faster print speed If you are using BarTender software see these videos Print speed Print darkness Distorted print Q Why is my LabelStation 342 printing text with jagged edges A lf text is distorted as below change the parallel lead to your printer 1 20 PER POUND 2 64 PER KILOGRAM Streaks of missing print LabelStation Industrial Q Iam using General Purpose ribbon on a LabelStation Industrial and it creases while printing causing short streaks Why is this A If this cannot be overcome by changing the print temperature and speed settings and or head pressure settings try printing with wax resin ribbon type 92 BLK PR443A If you are using BarTender software see these videos Print speed Print darkness White on black failure Q Why does my reversed print area white font on black background not appear as it should A You are probably using a printer font Printer fonts cannot be inversed For white on black printing use a Windows font or if the entire label is to be inversed use appropriately coloured label and ribbon
9. set to gap or vice versa BarTender videos Gap setting Black line setting Trailing labels are blank Q The printer produces one correct label followed by blanks then stops with a red error light How can correct this A Set the label template to Gap or Black Mark as appropriate BarTender videos Gap setting Black line setting Missing text or image LabelDirect only Q Blank labels are produced Drawing objects are printed but not the text How can remedy this A This is an early LabelDirect problem If your version of LabelDirect produces a print preview window before printing click the Restart button when this window appears Also switch the printer off for a few seconds Ideally upgrade to the latest version of LabelDirect Q Not all the objects on my label are printing even though they appear on screen What s happening A LabelDirect users only If any label object is located entirely or partly outside the boundary of the label then LabelDirect produces this message Warning One or more of the label elements extend outside the label This may result in a failure to print LabelDirect and BarTender users Even an empty text box left forgotten in a corner of the screen during development of the label can cause the label to come out blank Worse still if you have set LabelDirect to suppress the related warning you can be left with no clue to what s wrong Useful tip Select any object on the label
10. t biased towards the leading edge of the label you may have the label template set to Cut while the printer has no cutter Newer machines do not go to error state when there is no cutter fitted but do still retract the label a reversal of direction which causes creases to form in the ribbon This effect has been observed in an Industrial but may occur in other models Delayed response printing LabelDirect Q When printing labels of more than one column printing does not complete until the Done button is clicked Why NOTE In later versions of this software the Done button is called Return to Label Design A In some versions of LabelDirect label rows in multi column labels that are not fully populated do not print until the Done Return button is clicked Labels comprising three or four columns with only one or two of them containing print information might not print until the Done Return button is clicked E g If you print 10 labels on a four column wide label when you click to print you will get two rows comprising four labels each immediately then after clicking Done Return get one row comprising two labels and two blanks If you have set up to print one label only you will get nothing until you click Done Return This is intended to avoid wasting labels when successive batches are printed because it allows one batch to end and another to begin mid way across a row of label
11. t speed Print darkness Patchy and faded print Q Why are my labels patchy with faded print or random streaks of unprinted area A See photo below for a guide to the common imperfections RIBBON CREASES OVERHEAT Pic A Print density temperature set too high Ribbon expands under print head and forms creases Pic B Print density set too low Insufficient heat to deposit resin If temperature is only slightly too low then fade occurs on leading edges of black areas because of slow pixel warm up If individual pixels are visible fabric effect then temperature is far too low or print speed to high Pic C Print density set too high Orange peel or wave patterns occur on black areas Note that only the narrow part of the H is affected print head travelled left to right This is because when fewer pixels are energised the voltage to the head rises less demand on power overall and the temperature rises in those pixels still at work This can sometimes be compensated for by setting a lower temperature or faster print speed Pic D Using the Industrial or XL LabelStations some of the above problems can be compensated for by increasing the head pressure The photo shows this setting increased to 3 If you are using BarTender software see these videos Print speed Print darkness If you have a Pro 240 or LabelStation Industrial and are using 300 micron horticultural labels instead of the more common 200 micron thickness and
