(1) Curved material. When the printed material is curved, the UV printer is not able to print. If the arc material is printed, it is possible that the print pattern is not clear because the distance between the nozzle and the material is too far. If the nozzle and material distance is too near, may cause the nozzle collide the material, and damage the nozzle.
(2)High reflective material. Ni an ye fɛn barikama dɔ sɛbɛn, i n’a fɔ filɛlikɛlanw, etc., bawo UV yeelen yeelen min bɛ fɛn kan, o bɛna jira, walasa yeelen yɔrɔ min bɛ jira ka segin nugu la, walasa tintiri kɔnɔna na, o bɛ kɛ sababu ye ka nozzle kɛ ka a gɛlɛya{3}}
(3)Fɛɛrɛ kɛlen kɔfɛ, fɛn in mago bɛ funteni caman na, asidi barikama furakɛli. UV sɛbɛnnikɛlan ka inki bɛna kɛ sababu ye ka misali bɔnɛ, ka fɛnw tiɲɛ ani ka ko wɛrɛw sɔrɔ funteni caman kɔfɛ, asidi barikama furakɛli.
