analyze signs printer breakdown problem!

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

1 . Printing ink supply interruption may be caused by the following reasons:
A. Ink cartridge ink is too high or too low. Generally , 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 printhead and ink supply connections, if loosened , it is easy to cause the ink cartridge back into the supply .
E. print head quality. Especially the nozzle plate sealed well , observe the table if there is accumulation of ink , see the need to replace the printhead.

2 . Printing ink stains image appears , manifests itself in two colors of ink stains from each other , the drying time of the printed image is too slow or too fast print speed .
A, the working environment is too wet, especially for some easy-to- wet media , on the one hand to improve the operation of the indoor temperature and 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 meaning and solutions
(1) , the boot on the error, the error is Internal error: shutdown cd 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 meaning of the paper .
Solution: three possible ! Test paper ! Or puzzle card ! Or data lines ! The process of moving data lines should appear damaged ! Focus on examination 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, meaning 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 can reinstall the pulley off ; If the motor is no problem , for grating tape ; clean 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 the ink between the nozzle and the electric shock , burn easily shock with recommended treatment as soon as possible . Solution: If you are proficient
demolition machine , then you can put the motherboard , data cable, car plates removed after the clean look over there to try , not to change the car plate .Pictures of hot foam nozzle causes of damage.
4, printhead manufacturing process itself :
Under normal usage , the hot bubble than the piezo printhead life is shorter because of the hot bubble nozzle , the on-chip heater must provide high heat, 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 high heat and high pressure severe environmental changes , the thick wax structure will therefore loss , resulting in damage to the printhead is unusable.
Original jet printhead nozzle will not only ensure tightness and modified jet printhead can not guarantee (mainly NOVAJET alternative playing printhead), the main reason is the printhead of plastic , so not a good bonding , causing leak, the ink not normal ink and burned ; another reason is that in the conversion process, when you have to use ultrapure cleaning solution , and after cleaning the ink chamber to keep moist , otherwise any impurities after drying , adhered to the heating element , can cause thermal poor , will burn nozzle.
5 , the exclusion printhead quality problems other than the following references:
(1) the air duct For NovaJet machine , often because of the pipeline point of contact with the printhead or printhead loose leak , causing the ink back to the left side of the ink supply position , resulting in damage to the printhead air burning . If the bubbles contained in the ink filling process , a short circuit may cause burning in general , thereby causing failure of the entire group of injection holes . For HP2000CP, 2500CP, 3000CP, 3500CP, 50000,5000 PS machine , often because instead of ink to the ink cartridge filling , injecting too much air , when the bubble caused by lack of ink , the heating element will be because there is not enough ink in the printhead to heating the wafer so that the cooling overheating , causing damage .
(2) electrostatic interference .
The work environment is too dry , it will generate a lot of static electricity directly , as a direct result printhead circuit damage ; or using print materials, especially in the use of plastic -based materials , such as PP, when the adhesive media , will produce a lot of static electricity ; damaged printhead or cause impurities accumulation of damage caused printhead clogging .
(3) external voltage.
External voltage is too high or unstable , the printhead, especially to replace the printhead NovaJet great impact , may cause the machine to burn printhead or does not recognize the printhead.
(4) pay attention to operation and maintenance.
For Epson Series printhead, the direct cause of their damage is physical damage , that is due to the paper and other media Alice, scratching the bottom of the printhead during printing sheet metal hole , causing damage to the printhead orifice , and can not properly ejected. NovaJet Machine right printhead maintenance station and right of the cleaning cartridge HP5000 machines should always take down with pure water cleaning to prevent the plot caused by too much ink printhead clogging. if HP5000 printhead at the bottom of the plot too much ink will print orifice plug , remove with warm water to clean 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 printhead failure
