Change of paper roll

If the problem started when you changed label rolls, the problem is most likely the newly installed label roll. In the picture below is an extract from the Dymo Users Guide going over print quality issues.

This is not the correct printer when you have a lot of different label sizes.
In your case you should always do a callibrate when changing your labels.
You should use a toshiba printer (bsa4 of the new BEX) which i think would be more suitable.

The new labels are probably not thermal labels. Test them by applying heat to the surface and see if they turn black. If they do not change, then they are thermal transfer labels and not direct thermal. Contact your label vendor and have them replaced.

Are you getting any flashing lights that could perhaps indicate a paper jam or maybe the paper isn't loaded correctly?

Were the new labels thermal paper? Thermal printers need specially made paper to work right.

You get the error because the printer doesn't see any paper.
There are paper guides that need to be set for the size of the labels being printed. If you are switching from a 4" wide roll or sheet to a 3 1/2" label, you will have to move the slider in about 1/2". You will also have to calibrate the printer when you change label stock. If it won't calibrate, make sure the photoeye is hittint the break between labels. The photoeye is located where you insert the labels into the printhead path.

There is a problem with a print cartridge

Solution

Follow each of these steps until the problem is resolved:

1. Remove and then reinsert the print cartridge(s) into the printer.
2. Clean the print cartridges automatically using the Clean Cartridges option in the Printer Assistant.
3. Manually clean the print cartridges and print cartridge cradles:
   • Open the printer cover and wait until the carriage moves to the center.
   • Press the Power button to turn off the printer.
   • Disconnect power cord from the back of the printer.
   • Remove the print cartridges and place them on a piece of paper with the nozzle plate facing up.
   • Lightly moisten a cotton swab with distilled water.
   • Clean the face and edges of the print cartridges with the swab. Do not touch the print cartridge ink nozzles or copper contacts.
   • Wipe the underside of the print cartridge cradle walls using a clean, moistened swab.
   • Reinsert the print cartridges.
   • Close the printer cover.
   • Connect the power cord to the back of the printer.
   • Press the Power button to turn on the printer.
4. Calibrate the print cartridges.
5. If the light is still flashing, replace the print cartridges.

Issue

The print cartridge has partial loss of electrical interface with the carriage connections

Solution

1. Print a printer self-test by holding the power button down with a pencil and opening and closing the top cover four times.
2. Check the nozzle self-test pattern in the self-test print out. If one or more of the solid rectangular areas are missing, an electrical contact problem may be present.
3. Remove and then reinsert the print cartridge(s) into the printer.
4. Print the document.
5. If the problem persists, follow the steps listed above for cleaning the print cartridges and print cartridge cradle.
6. Try printing again. If the problem continues, replace the print cartridges.

one side of the paper will be sensitive to heat and the other side won't be. If it is thermal paper run a pen without the actual ink part sticking out of the pen or use a key from your key ring in your pocket over the paper the friction should leave marks on the thermal side of the paper.
you may have the paper in with the non thermal side facing the heat printing part of the paper. Or you have the wrong paper.

ld4028-10a or ld21084 may be the label ? not sure its 40 mm wide not 55 mm or 2.2 inch

We have found a reset that we use.
We unplug the printer and then we hold down the feed button and we keep holding down the feed button while we plug back in.
It goes through some sort of a reset and this sometimes works.
