DX5 head eco solvent printer Repairing
DX5 head eco solvent printer Repairing.
I. Analysis: print head blockage or arrive Life.
Workaround: < 1 > If HP2000CP and 3000CP series machines , first choose Align Printhead more positive on the panel , then select Check Printhead correction . If many shortcomings appear Check Printhead ejected proofs on the need to change or clean the ink head .
< 2 > If the HP5000 machines , first played test strips : Untilities - test prints - images quality print, if no color test strip , then Garra has been unable to use , you need to replace the ink head ; If the color bar complete , you can replace the print head , to see if the bottom of the plot print head ink too , can continue to use the general cleaning. Please refer to the cleaning method described in detail below .
< 3 > If Novajet machine , you need to print a test strip cleaning , nozzle if the nozzle is displayed with black patches , a general description of the sprinkler nozzle has been damaged and can not continue to use ; If the middle broken sprinkler nozzles , a general description of this Nozzle is blocked by the cleaning can continue . NovaJet machines can be accomplished through the absorber clean , but also scored for manual cleaning . Cleaning method is soft paper about the first few minutes with warm water , and then with no confetti or designed with a soft cloth slightly moistened Garra or dry naturally , avoid wiping Garra , dried and then start printing.
Second, the analysis : poor ink absorption medium
Solution: Try some standard good ink absorption medium , dark colors can be observed when printing department has no cracking phenomenon and the phenomenon does not absorb ink and dried slowly , if there is this phenomenon, the need to replace a standard medium.
Third, the analysis: the ink quality problems due to thermal foaming machine when printing ink to be a long time in high temperature ( 340 degrees Celsius ) , the use of inferior printing ink will produce some sediment , etc., caused by clogged ink heads , print streaks phenomenon .
Fourth, the analysis: other reasons
Workaround: < 1 > to improve the working environment is too dry studio , media electrostatic discharge excessive use , will have a lot of static electricity , or cause nozzle clogging impurities accumulate ; interference picture output effect, especially prone to streaks.
< 2 > attention to the daily operation of the bottom of the ink head nozzle plot too much ink , brush cleaner dirty , dirty and back of the chip , will cause the output image to produce a continuous streak .
< 3> The use of inferior quality cable using a parallel printer cable , or non- IEEE1284 standard parallel cable printing ; cause interference weak current output image quality , color output that is inconsistent or streaking.
< 4 > Check for loose or stepper motor gear dirty
< 5 > Adjust print speed if the machine is set too fast print speed , there will be stripes , HP machines usually use medium speed printing , NOVA machine can slow down the speed of the carriage , prone to streaks piezoelectric machines generally use 360DPI print .
Section NovaJet inkjet printer for printing ink off the ink stains and image output
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. Garra and cartridges , especially for connections, if loosened , it is easy to cause the ink cartridge back into the supply . E. The quality of the ink head . Especially the nozzle plate sealed well , observe the table if there is accumulation of ink , see the need to replace the ink head .
2 . Print the image appears manifests itself in two colors of ink stains each ink stains , the printed image is too slow drying time ( ie, print speed is too fast ) ; main reasons : A. Work 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 . Set in black ink for use : CMYK replacement will reduce the amount of ink K , but will affect the black luminance .
Section Garra routine maintenance on HP5000/PS specific operation and in accordance with our long-term experience , summed up the following points when using the machine for your reference , in order to improve the life of the print head :
1 . In business volume relatively long time , the best every day ( 8 hours or so ) will print head removed from the machine, can not afford fiber or paper with a soft cloth or paper towel dampened with a concentration of 95 % of medical alcohol to clean the bottom of the print head and side chip, and ink car slot chip part ( avoid wiping the print head nozzles ) .
2 . Since the machine during operation , the right-most part will often scraped clean box plot print head ink , so after a period of time to wash or replace the cleaning cartridge . The contact cleaner stick with white , the printer will default to the new cleaner.
3 . When filling the ink into the cartridge inside , to try to drain the air ; otherwise it would air intake duct and to the printhead , causing the print head air burning may cause the ink to print off or burn print head.
