In order to have your printers in good working conditions, you have to make the following preventive measures both regularly and unregularly.

Check the ink and make up level, when they are lower, please add in time according to requirements.

Clean and dry the print head, pay attention to the auto cleaning program when turning on & off the printers.
Clean the fan filter regularly.
Clean the installation and fixed device of the photo sensor regularly.
Check the installation and fixed device of the photo sensor & print head regularly.
Check the power supply and ground wire regularly.
Daily Maintenance and Common Faults

The printers are with auto diagnosis function. Customers could find the common faults and solve them via the icon in the screen, working status column or the status reminder in the system menu. You can obtain the parameters from the calibration menu or press key i beside the screen directly, then you could know more about their running status.

How often to clean the noozles?
Normally, if you are going to shut down the printer for over 15 days, remember to remove the nozzle and clean it thoroughly. To be specific, based on the different brands and different model, customers should clean the nozzle according to the printer manual.

Use consumables correctly
The inkjet printer nozzle is very small, its diameter is from 40-70u. Customers has higher requirements on ink diluent, the messages should be dry rapidly, higher adhesion. Normally, ink is composed of resin, make up, pigment and etc. The diluent is composed of makeup, active agent, stabilizer and other materials. There are strict process and quality control in the production of consumables, after raw material inspection, purification, mixed ingredient, grinding, reaction, stability, three stage filtration, filling, inspection and finally forms product. The diluent is researched and developed based on the features and characteristics of the inks, it constantly makes up the materials that consumed in the ink and repair the ink structure that are damaged due to the circulation.

Using inferior consumables will cause frequent blocking of the nozzle, ink filters & ink circuit, bad drop charging & printing quality as well as the corrosion of machine components.

Ink jet printer has strict requirements on its consumables performance indicators. Such as viscosity, granularity, conductivity, drying time, adhesion, corrosion, PH value. All these should be at certain range. Consumables that are from different factories have different models cant be used universally.

Inkjet printer working principle and history development

Inkjet printer takes advantage of the principle that charged ink particles which could be deflected in high voltage electric field to print images, messages and numbers. It is a high technology product that integrated the mechanical and electrical. It is widely used on food industry, cosmetic industry, pharmaceutical industry, auto parts processing industry, cable industry, aluminum plastic pipe industry, tobacco and wine industry and other fields as well. The printer is able to print production date, batch number, barcode and trademark logo, anti-counterfeiting mark and Chines words. It is the powerful equipment to implement health law and promote packaging modernization.

The inkjet printer theory was invented in late 1960s, but the commercial printer did not come out until 1970s.
Inkjet printer working as the carrier of inkjet technology is a kind of industrial production equipment. Generally, users have following requirements on it：

1、 Simple and convenient to operate and maintain；
2、 Stable performance, lower faults rate；
3、 Reasonable cost, high efficiency and long working life；
4、Good printing quality and clear characters. When customers need print company logos or clear Characters   and barcodes, high resolution inkjet printer is suggested.
