1. Check whether the pull wire of the print ribbon is disconnected. If it is disconnected, the ribbon pull wire should be replaced.
2. Adjust the ribbon cartridge and ensure it is correctly placed on the ribbon rotation axis.
3. Check whether the ribbon is stuck in the ribbon box and whether it has been pulled off. Open the ribbon box to inspect the ribbon, and reinstall or replace it if necessary.
4. Check if the ribbon cartridge on the ribbon tape knob rotation is flexible. If it is not flexible and tends to slip, the ribbon cartridge should be replaced.
5. Examine whether the ribbon rotating gear in the ribbon cartridge is worn. If it shows signs of wear and tear, the ribbon gear needs replacement.
6. Inspect whether the drive ribbon’s left and right movement of the ribbon drive shaft is worn. If so, replace the drive shaft.
This machine has a notable drawback: the ink in the cartridges dries up over time without being used, gumming up the print heads.
Several steps can be taken to rectify this issue:
Firstly, check if there is enough ink in each cartridge and refill as needed.
Secondly, power the machine on and off multiple times to allow the ink to automatically fill in.
Thirdly, refrain from rushing to print immediately after booting up. Instead, access the print preferences on the computer to clean the print head. After cleaning, print a test copy to assess the quality. If necessary, repeat the print head cleaning process.
Fourthly, some printers feature a print head cleanup button on the exterior. Press and hold it for a few seconds to initiate automatic print head cleaning. Observe whether the ink flow through the tubes is uninterrupted. Additionally, toggling the printer power on and off several times can also aid in resolving the issue.
