DX5 hd eco solvent printer Repairing

large format DX5 hd eco solvent printer can not working, follows to answer you all problem with DX5 hd eco solvent printer different problem toRepairing.


I. Analysis: print hd blockage or arrive Life
Workaround: < 1 > If 2000CP and 3000CP series machines , first choose Align Printhd more positive on the panel , then select Check Printhd correction . If many shortcomings appr Check Printhd ejected proofs on the need to change or cln the ink hd .
< 2 > If the 5000 machines , first played test strips : Untilities - test prints - s quality print, if no color test strip , then Garra has been unable to use , you need to replace the ink hd ; If the color bar complete , you can replace the print hd , to see if the bottom of the plot print hd ink too , can continue to use the eral clning. Plse refer to the clning method described in detail below .
< 3 > If Novajet machine , you need to print a test strip clning , nozzle if the nozzle is displayed with black , a eral description of the sprinkler nozzle has been damaged and can not continue to use ; If the middle sprinkler nozzles , a eral description of this Nozzle is blocked by the clning can continue . NovaJet machines can be accomplished through the absorber cln , but also scored for manual clning . Clning 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 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 hds , print strks phenomenon .

Fourth, the analysis: other rsons
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 strks.
< 2 > attention to the daily operation of the bottom of the ink hd nozzle plot too much ink , brush clner dirty , dirty and back of the chip , will cause the output to produce a continuous strk .
< 3> The use of inferior quality cable using a parallel printer cable , or non- IEEE1284 standard parallel cable printing ; cause interference wk current output quality , color output that is inconsistent or strking.
< 4 > Check for loose or stepper motor gr dirty
< 5 > Adjust print speed if the machine is set too fast print speed , there will be stripes , machines usually use medium speed printing , NOVA machine can slow down the speed of the carriage , prone to strks piezoelectric machines erally use 360DPI print .
Section NovaJet inkjet printer for printing ink off the ink stains and output
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. Garra and cartridges , especially for connections, if loosened , it is sy to cause the ink cartridge back into the supply . E. The quality of the ink hd . Especially the nozzle plate sled well , observe the table if there is accumulation of ink , see the need to replace the ink hd .
2 . Print the apprs manifests itself in two colors of ink stains ch ink stains , the printed is too slow drying time ( ie, print speed is too fast ) ; main rsons : A. Work environment is too wet , especially for some sy-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 5000/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 hd :

1 . In business volume relatively long time , the best every day ( 8 hours or so ) will print hd 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 cln the bottom of the print hd and side chip, and ink car slot chip part ( avoid wiping the print hd nozzles ) .

2 . Since the machine during operation , the right-most part will often scraped cln box plot print hd ink , so after a period of time to wash or replace the clning cartridge . The contact clner stick with white , the printer will default to the new clner.

3 . When filling the ink into the cartridge inside , to try to drain the air ; otherwise it would air intake duct and to the printhd , causing the print hd air ing may cause the ink to print off or print hd.
