Firstly with the printer turned on, press and hold the feed switch until the light flashes 4 times. Release the button when you see the 4 flashes and the printer will reset to factory defaults and calibrate. If this doesn't work you will have a Gap/Blackline sensor failed, this will need to be replaced.

Ovens spark up with gas and go out will not run

There is something wrong with your flame detection system... Try to clean the gap, sensor and the wires... If the wires all coated with grease, the grease will serve as a conductor and will short the circuit out so it will sense that there is no flame. If this still does not work out fine, try to see if the gap is set fine for the flame detection and there is no cut in the wire. Otherwise, you may need to change a little module called flame detection module.

No gap detected

This could be caused by a couple of issues:
  • Dirty sensor (use compressed air and blow out printer)
  • Wrong media (using labels with black bars obscuring the gap and making it non-readable by sensor)
  • Wrong label format for size of labels used (make sure label size matches the template size)

Gap not detected

GAP NOT DETECTED error in displayProduct: T5000rSymptom

GAP NOT DETECTED error in display.
Possible Cause

Dirty media sensors, wrong label length
Recommend Solution

Clean the upper and lower media sensors by spraying them with dry air. This should bedone every time the media (label stock) is changed.

Before running the Auto-Calibrate operation, check the QUICK SETUP or MEDIA CONTROL menu for the 'Label Length' parameter. It should be set to the length of the label, not counting the gap.

Check that the sensor type has been set in CALIBRATE CTRL menu to match the media and ribbon.
"Gap" Select when using media with a liner space between die-cut labels or when using tag stock with notches or holes as label length indicators.
"Mark" Select when using media that has horizontal black marks located on the underside of the label liner or tag stock.
"Advanced Gap" Select when media is gapped but also has a dark background.
This sensor arrangement looks through the ribbon, and will not work if ribbon is too dark.
"Advanced Notch" Select when media has a notch that is placed in a dark line on the back of the stock.

Check the position of the media sensor. It should pass through the center of gaps or marks or notches, but not through pre-printed areas if possible.

Run Auto-Calibrate in CALIBRATE CTRL menu, which sets Gap and Paper Out Thresholds

I have an Aurora Shredder -- Model #AS1512X. Paper got jammed and I pulled the paper out and now the shredder will not work. Any ideas as to how to fix this?????

Check safety and detection switches. 1. Safety is on the bottom and left or right side of shredder unit inside a narrow gap. On the bucket's wall there is a natch witch should go into the gap, when you put shredder correctly. Check if switch and natch are on the same side. Simple turning around will solve problem. 2. Check a detection switch. It is located in the middle, inside of gap. This switch engages and turns motor on when you put paper into shredder. In other words sheets of paper should push the switch first before touching shredding rolls. If you have digged out that paper from the top side, chances are you have broken that switch.

Manual calibration of the printer is not working

TLP does not support the notched labels bcoz the sensor is in the center.. TLP can detect labels with GAP/BLACKMARK and Center Hole

My label printer quit printing the barcodes on the labels.

I am just getting a series of lines.

I have tried unplugging the machine and still have the same result.

I have tried to calibrate but that is not working either.

Thanks in advance for any suggestions.
