- WHAT SHOULD WE PAY ATTENTION TO WHEN CHANGING PRINTER MOTOR?
Each printer has two important motors, one is serve motor, which can control the movement of carriage, the other is stepping motor, which can control the movement of the paper. When the printer cannot work well due to some problem of the motor, the operator should master some skills to replace the motor.
We should pay attention to several points when changing the motor:
A: We should cut off all power when replacing motor. It's better to use a screwdriver for stitches when devanning. We must follow certain rules to avoid confusion phenomenon in case of the damage to the mainboard when clearing stitches.
B: When replacing motor, firstly we should take the belt and pay attention to the details. When we install and remove motor, be careful not to damage the motor. When we need to update to a new equipment, we’d better adopt same equipment when replacing to avoid the secondly damage.
- WHAT SHOULD WE PAY ATTENTION TO WHEN CHANGING THE DAMPER OF PRINTHEAD?
For printer users, damper is not strange. Damper is an important small accessory, which can influence the quality of printed picture, however, when we need to change damper?
Damper is a translucent part above the printhead, there is half a bag of ink and a filter. The filter is mainly used for filtering the impurities that ink brings, to reduce the probability of printhead blocking. You will notice that there are too many impurities, damper filter blocking, broken ink in printing process when you have used printer for a long period. For such small trouble, manufacturer generally recommends replacing the damper.
We often see some friends ask, “how to clean damper without replacing it?” As Stormjet manufacturer, we recommend replacing the damper instead of washing it! Methods for cleaning the damper from the internet: We can make out whether it’s the problem of damper or printhead and then prepare a screwdriver, syringes, disposable cups, paper etc., to remove the damper for cleaning. Note: if you are not familiar with this, don't try. Under improper operation, it may be penny wise and pound foolish. For the replacement of damper, the price is not expensive (It’s better to use the damper that manufacturers recommend or use the original damper from manufacturer).
- WHAT SHOULD WE DO WHEN THE CARRIAGE COULD NOT RESET WHEN THE PRINTER IS SWITCHED ON?
There are following reasons that the carriage can’t reset:
A. The reset sensor is in poor contact.
B. The raster decoder is damaged.
C. The computer is not connected to the machine.
D. The drive board is burn out.
A. Do not insert the USB line, when the LCD shows COOLCOLOR state, put the left and right button to see whether we can move the carriage, or put the up and down button to see whether the paper can go back and forth, if not you need to replace the driver board.
B. If the carriage moves to the left, check whether the reset switch is loose or replace a new one.
C. Check the encoder sensor or replace new one.
D. Switch on the printer, if there is nothing wrong with the points above, check whether the USB cable connection is correct, when pluging USB cable in computer hardware device manager, check whether you can find “printer”, if not, please replace the main board.
- WHAT SHOULD WE DO WHEN THE CARRIAGE STOP AT BOTH SIDES IN PRINTING PROCESS?
What should we do when faced up with the phenomenon that the carriage stops, the printing speed is slow or carriage stops suddenly while the carriage goes at both sides of the guide rail? Below we would like to further explain it for you, how to solve these problems when we meet with this kind of problem.
The main reasons for this kind of problems are:
A. The printing wire connector is loose.
B. The printing wire is too long.
C. The servo motor is damaged.
A. Check if there's any loose for printing wire and then change the printing line to avoidn the problem in the printing wire.
B. Too long or poor quality printing wire will affect the validity of the transfer, so we recommend the length of printing wire should be less than three meters.
C. Replace the servo motor.
- WHAT SHOULD WE DO WHEN THE PRINTED IMAGE IS FULL WITH INTERVAL STRIPES?
There are two main reasons:
A. The reasons of clogging printhead.
B. The reasons of aging printhead.
A. Firstly print on the clean testing stripe, when it shows color piece in the printhead nozzle, it means the printhead nozzle has been damaged, we cannot continue to use it and we need to replace a new printhead.
B. When it shows break line in the testing stripe, it means this printhead nozzle is clogging, we may continue to use by cleaning it.
Printhead cleaning method:
We can clean the printhead by using the ink absorption and it can be cleaned manually. First use warm water to soak it for a few minutes, use soft paper without scraps or a piece of specific cloth dig in the printhead or dry in the air. We mustn’t wipe the printhead at this moment and we can do print test after drying.
- THERE IS A GRID IN PRINTING FIGURE AND THE INK CAN’T PRINT CONTINUOUSLY
The encoder sensor is dirty, we need to use cotton swabs dipped in water wipe the encoder sensor a few times more and dry the water with dry cotton swabs.
- WHEN THE INK CAN’T RECOGNISE THE CARTRIDGE
Decryption card is loose, we need to insert again or decryption card is broken.
- WHEN THE PRINTHEAD IS OUT OF INK
1. The carriage is too hot, we need to turn down the machine to recover.
2. The electric shock belt is broken, we need to change to get an electric shock.
3. The printhead is clogged, we need to clean and wash the printhead.
4. The refill tube interface is blocked, it is necessary to remove and plug a few times more.
5. The printhead interference, change the printhead position, and put a piece of paper between the printhead and electric shock belt to check the interference is from which printhead and replace the printhead.
6. If four printheads are out of ink at the same time, after exclusion of printhead interference, it’s because of the carriage broken.
