4. Getting Ready for Printing
Switch ON Procedure
Follow these steps to switch ON the printer:
Step 1: Switch ON the MCB from back side of the machine.
Step 2: Check whether an Emergency button is pressed or not. If the Emergency button is pressed, then
immediately release it.
Step 3: Switch ON the Power button of the machine. Automatic initialization of machine gets started, as
shown below:
Fig 7: Switch ON the Power Button
Step 4: Firstly, Z axis gets initialized and capping goes down.
Step 5: After the initialization of capping, X axis gets initialized.
Step 6: Capping start verifying the maximum up limit and stay on defined position.
Step 7: Wiper unit gets activated and starts the initialization process.
Step 8: Refill water tank with the clean water.
Step 9: Check the ink level in the Main tanks.
Step 10:Check the Waste Ink Bottle and empty it, if full.
Step 11: Load the fabric and engage the Press Roller (Refer to the Loading Fabric section).
Step 12: Take care about fabric handling from supply and take up sides.
Step 13: Switch ON the Feeder and Dryer units.
Step 14: Check Print Head Nozzles status by issuing the Nozzle Test command. If nozzle test result is not
OK or nozzles are blocked, clean the Print Head by performing the steps given in the Head Cleaning
section.

Step 15: Check whether Jetting and Brush Roller working properly or not.
Step 16: Rip the image file using the Ripping software provided with the machine.
Step 17: Set the print origin to specify the printing starting position.
Now, the printer is ready for printing.

Filling Ink
To refill ink, remove the Main Ink Tank cap and refill ink as per the color sticker. The Main Ink Tank is
shown in the image below:
Fig 12: Displaying the Main Ink Tank
Points need to remember:
•The Main Ink Tanks are located at the back of the printer
•The capacity of ink main tank is 10Litre
•Ink in the Main tanks is pumped to the Sub Ink Tanks located at the Carriage Assembly.
The Ink Sub Tank is shown in the image below:

5. Glue Coating
Glue Implementation
Glue is composed of three different chemicals and two solvents.
Chemicals:
•Prima: It is used as a primitive coat, for smoothening the belt surface. This is to be done only when
the previous glue layers have been washed completely.
•Therma: It is used for an intermediate coat, for activating and deactivating the glue according to
the temperature variation.
•Perma: It is the final glue coat, to make the belt sticky for the fabric.
Solvent:
•Cleantek: This liquid solution is used for the renewing/refreshing the tackiness of the Perma
adhesive. In digital printing, the adhesive film must be even, thin and hard (to maintain accurate
distance in between print head and fabric). The Cleantek removes foreign elements, like dust and
micro fibers, from the top layer, hence enhancing the adhesion property of the Perma. If there is
no improvement using the Cleantek, it means it’s time for a coat of the Perma.
•Solvtek: This is used either to dilute the adhesives, or to complete removal of the all adhesive
layers. The following are the two main reasons for removing all the glue layers:-
oWhen the thickness of the adhesive layer goes on increasing due to multiple coat of the
Perma.
oWhen the glue layer feels smudgy or groovy (in terms of evenness).
Stages of Glue (Adhesive) Process
Stage 1: Prima coat
Stage 2: Therma coat
Stage 3: Perma coat
An interval of 4hrs is required for the glue to set and dry. After each glue coat, run the glue cycle for 50
minutes with glue heater ON. After final coat of Perma, printing can be started. The third stage is generally
a repetitive process, repetition depending on the frequency of printing hours. And when the glue coats
get uneven or once in 2-3 months, whole process has to be repeated after removing existing Glue layers.
Note: Average consumption for the Cleantek solvent is 500ml for one time.
Approximate consumption of chemicals for a year:
•Prima: Approx. 2 Ltrs
•Therma: Approx. 2 Ltrs
•Perma: Approx. 5 Ltrs
•Cleantek: Approx. 4 Ltrs
•Solvtek : Approx. 10 Ltrs

Page 18 of 62
Metro (Kyocera Head)
Note: Actual consumption depends on the work load, fabric type, and the maintenance. Generally, shelf
life for these chemicals is approx. 4 years.
Shelf life for this chemical are approx. 4 years. Some of the Glue are having these chemicals as base and
it harms the belt or adversely affects the life of the Printing Blanket (Conveyor Belt):
RECOMMENDED
•Alcohol
•Methyl alcohol
•Ethyl alcohol
•Isopropyl alcohol
•Ester
•Butyl acetate
•Ethyl acetate
NOT RECOMMENDED
•Aromatic

Glue Process Preparation
Follow these steps for glue process preparation:
Step 1: Keep the ventilators and exhaust fans ready.
Step 2: Lift up the Press Roller and remove the fabric, if any.
Step 3: Run the Wash Cycle from HMI, simultaneously belt can be cleaned by wiping with cloth.
Fig 14: Running the Wash Cycle
Step 4: Put masking PVC tape on both edges of the Conveyor Belt, by simultaneously moving the belt
through HMI in slow speed.
