Troubleshooting
Getting Started
Problem | Cause | Solution |
Printer does not operate even though board and mechanism are connected | Is the power supply connected and turned ON at the circuit side terminal portion, e.g. at a power extension strip? | Ensure the power supply is securely connected, then turn the power ON and try to print again. |
Are the logic supply and head power supply GNDs connected in common? | If not, connect GNDs in common and check again. | |
Has an error occurred? | Make sure the paper is inserted in the correct feed slot. | |
Is the paper detection sensor ON? | ||
Is the head cable properly connected? | ||
Make sure the platen or printhead is set. | ||
No color prints even if the printer operates. | Is the front and back of the paper reversed? | Ensure that the paper is positioned to feed in the correct direction and check operation again. |
Is paper sensitivity sufficient? | Color will not print if the paper sensitivity is too low. Use paper with a higher sensitivity and check it again. | |
Is paper thickness appropriate? | If the paper is too thick, the printhead will be raised too high to properly generate color. Change to a thinner paper thickness and check again. | |
Printer will not print out a test page. | Is the power ON? | Check if GNDs for logic and the head are commonly connected. |
Is the paper detection position set appropriately? Are the platen and head set correctly? | Confirm there are no errors. If so, correct each error situation. | |
Are the flex print circuit cable, ribbon cable, or discrete connection wires cut or disconnected? | Ensure both the cables and all wires are connected correctly, and try again. | |
Cutter does not fully cut the paper. | Is the paper thickness appropriate? | Make sure the paper is not too thick for the cutter. |
Is the cutter's blade angeled correctly (low height type)? | Ensure that the cutter's blade completely closes when cutting and that there is no paper debris caught in the blade. |
