analyze signs printer brkdown problem!

this article is to let you know how to analyze all different type of large format signs indoor outdoor printer brkdown problem!

1 . Printing ink supply interruption may be caused by the following rsons:
A. Ink cartridge ink is too high or too low. erally , the amount of ink can be maintained at preferably about 400ML.
B. System pressure imbalance. Unscrew the cap allows the ink tube system pressure balance.
C. Ink used incorrectly . If you do not use the outdoor ink ,3- 4 weeks after blocking the ink tube .
D. Ink supply pipe connections loose. Especially the printhd and ink supply connections, if loosened , it is sy to cause the ink cartridge backinto the supply .
E. print hd quality. Especially the nozzle plate sled well , observe the table if there is accumulation of ink , see the need to replace theprinthd.

2 . Printing ink stains apprs , manifests itself in two colors of ink stains from ch other , the drying time of the printed is tooslow or too fast print speed .
A, the working environment is too wet, especially for some sy-to- wet media , on the one hand to improve the operation of the indoor temperaturnd humidity , the media on the other hand should be kept after use .
Attempts to change one medium print .
B. Set RIP software, such as Mongolia and Thailand . Set the paper type for : CMYK70%-CMYK95%. Will adjust the amount of ink , black ink set in use :
CMYK replacement will reduce the amount of ink K , but will affect the black luminance .

3 pictures of common error in English mning and solutions
(1) , the boot on the error, the error is Internal error: shutdown voit o / r ange (l: 111 to R: 0 T: 11100).
Solution: Check the motor focus or flat cable .
(2), Internal ERROR: Shutdown Bad carriage paper sensor is not detected , according to the mning of the paper .
Solution: three possible ! Test paper ! Or puzzle card ! Or data lines ! The process of moving data lines should appr damaged ! Focus onexamination of test paper , grating , car plates .
(3) , 750 machines Powering into print a test strip , trolley to move to the edge of the paper , error : internal ERROR: shutdown Bad magio pid: 37
(astp value = 0 × 1100f, 0 × fff3f4)
Solution: Check the test paper , flat cable , bar grating , if good, will direct replacement car plates .

(4) , the card after the left turn back when the car went to the Lord, error : carriage axis failure, mning that resistance is too large .
Workaround: On the rails RBI machine oil , copper and apply alcohol to wash or replace copper sleeve ; look at the belt is not being wiped , you canreinstall the pulley off ; If the motor is no problem , for grating tape ; cln smooth bar .
(5) After the completion of the boot test paper , error : Internat ERROR: Shut down CB Set-Voltage failure (2,0 x3ff.11100).
This error message should be reported sometimes and sometimes not reported , so rare. It will cause drops of ink nozzles , and will get on with theink between the nozzle and the electric shock , sily shock with recommended trtment as soon as possible . Solution: If you are proficient
demolition machine , then you can put the motherboard , data cable, car plates removed after the cln look over there to try , not to change the carplate .Pictures of hot foam nozzle causes of damage.
4, printhd manufacturing process itself :
Under normal usage , the hot bubble than the piezo printhd life is shorter because of the hot bubble nozzle , the on-chip hter must provide highht, let the ink bubbles in a very short time , and then the ink is pressed outwards , forming an ink droplet is ejected . Ink chamber under highht and high pressure severe environmental changes , the thick wax structure will therefore loss , resulting in damage to the printhd is unusable.
Original jet printhd nozzle will not only ensure tightness and modified jet printhd can not guarantee (mainly NOVAJET alternative playingprinthd), the main rson is the printhd of plastic , so not a good bonding , causing , the ink not normal ink and ed ; another rson isthat in the conversion process, when you have to use ultrapure clning solution , and after clning the ink chamber to keep moist , otherwise anyimpurities after drying , adhered to the hting element , can cause thermal poor , will nozzle.
5 , the exclusion printhd quality problems other than the following references:
(1) the air duct For NovaJet machine , often because of the pipeline point of contact with the printhd or printhd loose , causing the inkback to the left side of the ink supply position , resulting in damage to the printhd air ing . If the bubbles contained in the ink fillingprocess , a short circuit may cause ing in eral , thereby causing failure of the entire group of injection holes . For 2000CP, 2500CP,3000CP, 3500CP, 50000,5000 PS machine , often because instd of ink to the ink cartridge filling , injecting too much air , when the bubble causedby lack of ink , the hting element will be because there is not enough ink in the printhd to hting the wafer so that the cooling overhting ,causing damage .
(2) electrostatic interference .
The work environment is too dry , it will erate a lot of static electricity directly , as a direct result printhd circuit damage ; or usingprint materials, especially in the use of plastic -based materials , such as PP, when the adhesive media , will produce a lot of static electricity ;damaged printhd or cause impurities accumulation of damage caused printhd clogging .
(3) external voltage.
External voltage is too high or unstable , the printhd, especially to replace the printhd NovaJet grt impact , may cause the machine to printhd or does not recognize the printhd.
(4) pay attention to operation and maintenance.
For Epson Series printhd, the direct cause of their damage is physical damage , that is due to the paper and other media Alice, scratching thebottom of the printhd during printing sheet metal hole , causing damage to the printhd orifice , and can not properly ejected. NovaJet Machineright printhd maintenance station and right of the clning cartridge 5000 machines should always take down with pure water clning to preventthe plot caused by too much ink printhd clogging. if 5000 printhd at the bottom of the plot too much ink will print orifice plug , remove withwarm water to cln off .

6. ink quality.
Ink contains a variety of chemical ingredients , often because the filter is not fine , viscosity is too high, but off moisturizer and other factors,resulting in printhd failure
