Defaulted components |
Fault phenomenon |
Failure cause |
Solution |
1 |
Vacuum bump |
buzzer alarm one time |
main vacuum bump broken; or negative pressure is too low; or the parameter of negative pressure meter is modified. |
replace the broken main vacuum bump or increase the negative pressure or reset the parameter of negative pressure meter, and reset the ink system. |
2 |
none |
buzzer alarm two times |
negative pressure exceed the limit. |
adjust the negative pressure to the normal level |
3 |
ink bump |
buzzer alarm three times |
continuous ink supply time is too long |
check if ink bottle is lack of ink. If yes, then add ink into it; If not, check if ink bump is broken or there is ink leakage. |
4 |
wires or circuit board |
buzzer alarm four times |
Outside devices control board fails to communicate with head control board. |
check the wire between outside devices control board and head control board. |
5 |
none |
buzzer alarm five times |
ink flows into the negative pressure tank |
check if the negative pressure is too high or if liquid level sensor is broken. The air tube should be cleaned or replaced. |
6 |
none |
buzzer alarm six times |
ink bottle is lack of ink. |
check which color ink is in lack and add it. |
7 |
UV lamp |
UV lamp don’t work; or sometimes work and sometimes refuse to work; UV curing is not complete |
filter cotton is too dirty; or voltage is not stable; or lifetime of UV lamp is over |
replace the dirty cotton; or check if the working voltage is normal; or replace the UV lamp. |
8 |
Shutter of UV lamp |
Shutter is blocked and can not open or close |
the block is caused by high temperature expansion |
find the failure cause and make the mechanical adjustment |
9 |
two level boat-shape switch |
UV lamp and air pressure bump refuse to work; the connector is burned. |
high current operation |
replace the two level boat-shape switch and be sure that the connection is tight enough. |
10 |
¢4X2.4 ink tube |
the negative pressure lower down when carriage is moving or there is ink leakage in the chain. |
ink tube wear from rubbing in the chain |
replace ink tube |
11 |
outside device control board |
error reported from software “the communication with outside device control board is failed” |
computer case is not connected with ground; or operate the communication wire in electrification; or open/close the printer frequently |
replace the outside device control board; be sure to close the printer and computer first before operating the communication wire; to be sure that the interval time is at least 30 seconds between each opening/closing machine. |
12 |
photo-electricity switch at the left origin point |
the left guide can not come back to the origin, and the photo-electricity switch indicator light is always bright. |
the photo-electricity original switch is dirtied by dust which blocked the light. |
Cleaning the switch by alcohol or replace a new one. |
13 |
computer |
The computer halts, all software can not be operated |
computer was attacked by virus |
Kill virus; or write down the temperature and voltage parameters and re-install the computer and software. |
14 |
raster or raster reader |
empty banding in vertical direction; or double images in horizontal direction; error report from software “error with raster” |
raster is dirtied by dust or wrong installation with raster reader |
clean the raster with alcohol or adjust raster reader |
15 |
the end cover of guide rail beam |
there is abnormal noise from the end cover of guide rail beam |
sympathetic vibration |
adjust the tightness of fixing screws |
16 |
none |
all the nozzles of black print head seriously slanting spray |
the head surface of black ink tend to be cured |
wipe the head surface with lint-free cloth for more times until it is recovered |
17 |
negative pressure adjusting button |
negative pressure is not stable which cause ink-drop |
dust enters into negative pressure adjust button which effects the air flow |
clean negative pressure adjust button monthly |
18 |
image data card |
can not found image data card |
the image data card is not inserted correctly or without driver software or gold fingers is dirty. |
insert the image data card correctly or re-install driver software or clean the gold fingers of card |
