transmission axle, gliding rail or bearing sleeve will make the work of the operator or the

printer difficult.

1. Cylinder

Each time when you begin printing or the printing is finished, the cylinder must be

checked carefully to remove any foreign dirt. Paper dust or dirt can be removed with a

clean scraper and oil dirt on the surface of the cylinder can be removed with the scraper

dipped in the solvent. However, never use any metal tool to clean the cylinder.

2. Gears

All the gears of the ink cylinder, plate cylinder and the greater pressure cylinder must

be checked regularly to see if there is dirt to cause any unnecessary tension or friction on

the gear and the gear axle (in severe cases, the printing quality can be affected). A better

tool for cleaning these gears is short steel brush dipped in the solvent. When the gears have

been cleaned, they should be lubricated again to suppress tear and wear, to reduce noise

and to make future cleaning easy.

3. Ceramic anilox roller

Each time when the ceramic anilox roller is cleaned, it must be cleaned thoroughly

and checked with a high-powered amplifier. The cleaning is better to be done when the ink

on the anilox roller is wet. This way, the ink can be effectively stopped from drying in the

roller holes. In general, a special chemical detergent is used to soften and dissolve the ink

in the roller hole. Method: Place the anilox roller in the detergent for a while and then

brush the surface of the roller spirally with a special brush. This is especially effective for

the severely blocked anilox roller with dried ink in the roller holes. After cleaning, pure

alcohol must be used to treat the surface of the roller, including gears and axle. When the

moisture is evaporated, cover the anilox roller with clean paper to prevent dust.

NB. If there is grease on the surface of the roller, clear it away with alcohol

immediately.

4. Bearings

The ink roller and the plate cylinder is of high precision; therefore, any foreign body

in the bearing or the bearing sleeve will lead to poor installation of the bearing and bearing

sleeve and unnecessary tension. Before installing the plate cylinder into the printer, the

bearing and the bearing sleeve must be checked and cleaned. After cleaning, thin oil must

be applied on the connecting surface.

5. Plate cylinder

To eliminate any possible changes, all the cylinders of the printer must be of high
