Incomplete characters , the printer ribbon cartrige is installed correctly completely over the print head. Changed the ribbon 2 times and I have the same problem with each new printer ribbon.

If one pin of your Epson LX-350 printer is not printing even though you have checked the print head and the white cable, there are a few other things you can try to troubleshoot the issue:

1. Clean the print head: Use a cleaning solution and a lint-free cloth to gently clean the print head. This can remove any buildup or debris that may be blocking the pin.
2. Check the ink ribbon: Make sure the ink ribbon is correctly installed and not damaged. If it is damaged, replace it.
3. Replace the pin: If the pin is damaged or broken, it will need to be replaced. Consult your printer manual or contact Epson customer support to find out how to order a replacement pin.
4. Check the printer settings: Make sure the printer settings are configured correctly, especially the character set and print density.
5. Check the software: If you are printing from a computer, make sure the software is configured correctly and the correct printer driver is installed. Try printing a test page to see if the problem persists.

If none of these steps resolve the issue, it may be a hardware problem that requires a professional technician to diagnose and fix.

PR-01724 Ribbon Break

The print ribbon is broken.

Possible Cause 1: The print ribbon has broken or is not installed.

Solution 1: Trim the broken ribbon evenly and tape the cut end of the ribbon to the ribbon on the take-up spool. Install the ribbon cartridge.
NOTE: Do not switch take-up spools when fixing.

Possible Cause 2: If the ribbon type is K or KT, the print ribbon is at the end of the roll.

Solution 2: Load a new roll of monochrome print ribbon.

Technical issues:

•If you have recently changed edge-to-edge settings using the SmartDriver, printing might be too close to the edge of the card. Change edge to edge settings.

•You might have moved the print ribbon while the printer power was off. The next card will print correctly. The printer is designed to allow you to fix problems while the printer power is on.

•If the print ribbon is stuck to the card, the Intensity setting might be so high that printing causes the ribbon to stick to the card. Lower the Intensity or power setting.

•The card design might be longer than the card size. Change the card design to be less than or equal to the card size in the long direction (3.37 inches or 85.60 mm).

•Printing might not be positioned properly on the card. Change the "Left/Right" position of printing (using the SmartDriver) so the printing begins and ends on the card.

If this is the thermal head model, you will need to have the print head replaced. These were also sold under the Dell label, so finding a used replacement printer may be more economical. If it takes ribbons, you will need:

Ribbons

This printer needs a ribbon cassette to print receipts.

Remove and inspect the ribbon cartrige, wind the knob and make sure that the ribbon moves and reinstall. Check that the correction tape is installed properly. Check that the ribbon plate assembly is not in the correction position. Try CODE RESET (Q key)

PR-01726 Ribbon Out
Out of print ribbon.
Possible Cause 1 : The print ribbon Cartridge is empty.

Solution 1 : Reload the print cartridge. Change the cleaning sleeve and replace the cartridge in the printer. Run a cleaning card as soon as printing is completed.

Possible Cause 2 : The printer ribbon is not loaded correctly.
Soultion 2 :Load the printer ribbon correctly and then close the cover.

Possible Cause 3 : This ribbon has been completely used.
Solution 3 : Use a new roll of ribbon.

Tips for Success
* When this message appears, replace the old ribbon with the new ribbon of the same type. The printer has already prepared the card data for this ribbon type. You can change the colors of monochrome ribbon (such as from dark blue to gold).

* If you must change the type of ribbon (such as (YMCKT to KT) when this message appears, install the new ribbon, cancel any cards waiting to print, and change the ribbon type settings. Finally, return to the card creation program to send the card data to print.

* If the ribbon was repaired, the wrong take-up spool was used. Repair the ribbon again, using the correct take-up spool.

If you cannot fix the problem contact your service provider for assistance.

FTB

Problem is with either with cards or with print head's mechanical alignment. Try with some different cards and for head get it tested by some authorised service person.

It sounds like you have one of two problems;

1) The ribbon cartrige it warn out or damaged, leading to no ink in a particular area.

More likely

2) The print head is damaged or warn out or is not connected correctly to the pritner. The print head may need to be reseated or if this does not fix the problem the print head may need to be replaced.

Yes quite possible pin broke on head, check ribbon is fitted correctly and has plastic sheild on front of it intact
