1, CTP machine surface maintenance
The outer surface of the cleaning output device protects the appearance and surface finish to ensure that visual indications and markings are clearly visible. What's more, regular cleaning reduces dust that can fall into the device when you remove or open the access panel. The areas that are most prone to dust accumulation are the fan box panel, the power box panel, the front and top panels, and the area where the plates enter and exit the output device. Reliable, high-quality output requires that the outer surface of the output device be kept clean.
Cleaning Before cleaning the outer surface of the output device, vacuum-dust all access panel seams to remove any accumulated dust. If the surface is often wiped clean with a dry cloth and the environment is relatively dry without steam, it may be sufficient if it is done. For more thorough cleaning, use a cloth moistened with water and a mild detergent. Wipe all remaining detergent thoroughly with a clean, damp cloth. (Warning: Do not allow water or other liquids to flow freely into the output device. This may result in electric shock, serious injury, and damage to the output device.)

Clean edge detection strip
To position the image to the edge of the plate, the output device uses an edge detection algorithm. The algorithm relies on a 741 mm (29.2 in) black non-reflective test strip placed on the surface of the imaging drum inside the output device, which is located on the surface of the imaging drum inside the output device next to the front-edge clamp. Edge detection strips must be cleaned every month to avoid edge detection errors.
To clean the edge detection strip:
1. Make sure the output device is not currently working.
2. Turn off the output device.
3. Open the front door.
4. Turn the imaging drum by hand until you see the edge detection strip. Note: Do not catch the right end surface of the imaging drum. This may damage the optical encoder in the imaging drum.
5. Wet a piece of cotton-free cloth with distilled water (suitable for delicate operations) and wipe the test strip in one direction only. (Be careful not to leave any fingerprints or smudges on the test strip. Wipe it with a clean dry cloth after wiping.)
Clean the plate roller:
1. Make sure the output device is not currently working.
2. Turn off the output device.
3. Open the front door.
4. Gently wipe the plate roller (bright blue) by gently wiping the other hand with a damp, lint-free cloth (suitable for delicate operations). (Be careful not to leave any fingerprints or smudges on the test strip. Wipe it with a clean dry cloth after wiping.)
Clean the imaging drum:
1. Make sure that the output device is not currently imaging plates.
2. Turn off the output device.
3. Open the front door.
4. Gently wipe the drum by gently wiping the other hand with a damp, lint-free cloth (for delicate operations). (Be careful not to leave any fingerprints or smudges on the test strip. Wipe it with a clean dry cloth after wiping.)
