How To Solve The Malfunction Of UV Printer Raster Decoder?

Before understanding common troubleshooting methods for UV printer raster decoding, let's first have a brief understanding of the function, purpose, and common faults of the UV printer raster decoder.
Before understanding common troubleshooting methods for UV printer raster decoding, let's first have a brief understanding of the function, purpose, and common faults of the UV printer raster decoder.
1、 The Function and Application of UV Printer Raster Decoder
The grating decoder installed on the UV printer is used to identify or read the positioning data of the grating bars. After reading the data, the model is transmitted to the system control program through the integrated circuit center. The grating decoder device is installed after printing the car head,
The grating bar is stuck in the middle of the decoder (not in contact, in the center position). After the control program issues a printing command, the positioning scale of the grating bar is read during the movement of the decoder to ensure the distance of the car's movement.
Raster decoders are widely used in digital printing equipment such as UV printers, photo machines, inkjet printers, and digital printing machines.
2、 Common faults of UV printer raster decoder
During the use of UV printers, if there is a malfunction in the raster decoder, the accuracy of the car's movement during the mobile scanning printing process will deviate, resulting in displacement of the printed pattern, blurring, tilting of the printed image, and the inability to run printing normally.
Firstly, the grating decoder of UV printers can have a lifespan of 1-3 years for imported accessories, around 1 year for domestically produced ones, and over 2 years for domestically produced ones with technological advancements.
The general service life has reached, it is recommended to replace it with a new accessory.
Secondly, human factors may cause malfunctions during operation, usually due to delayed maintenance, unstable quality of low-quality UV printers, and accidental damage during operation. After discovery, replace it with a new one in a timely manner, and the price of accessories is not expensive.
3、 Maintenance of UV printer grating decoder and grating strip
Before starting and running, the raster decoder is usually rarely cleaned. If special circumstances arise, it can be gently wiped with specialized alcohol. For the maintenance of the raster strip, it is recommended to use a dust-free cloth or degreased cotton cloth alcohol to wipe once a week according to the frequency of use.
When wiping and maintaining, gently move it in one direction and do not move it back and forth to avoid damaging the surface gloss of the grating strip.
