White Dry Hot Melt Ink Roller Adhesive 36mm Diameter 32mm Height

Can't the ink wheel printer type clearly? What is the cause?
Whether the ribbon or ink cartridge needs to be replaced, the stylus printer should check whether the needle is damaged; If it's laser, see if you need to add powder, and then look at the printer settings. That's basically it.
There may be several reasons:
1. The pressure between the character wheel and the rubber roller is too small, so the adjusting block can be adjusted to make the pressure between the character wheel rubber roller and the rubber roller reach a suitable state.
2. The ink wheel is not heated completely and the preheating time is not enough, so it is necessary to wait for the ink wheel to be heated to a softened state.
3. The ink wheel runs out of ink, so replace it with a new one.
4. The word grain is damaged and needs to be replaced with a new word grain.
5. The temperature of ink wheel and character wheel is low, check whether the heating system is normal, check whether the thermocouple or heating pipe is normal, and replace it if it is abnormal.
