The common faults in digital composite machines are not working, scanning starting light sources, near -Yan copying keys, work normally, but copying does not output, high -pressure generators do not work, etc.Let ’s take a look with Xiaobian.
Common failure of composite machine
1. Cause -sensitive drum (drum or plate) pollution
Causes and exclusion methods:
1) A sensing drum fatigue.If you have severe fatigue drums, you should change the sensory drum;
2) The electrode electrode voltage is insufficient or the electrical lamp illuminance is insufficient.Adjust the voltage or switch the lamp gun;
3) Election voltage is too low.Move the electric halo to the drum surface slightly;
4) There are too many ink powder in the display box.Adjust the carrier in the display box, the proportion of ink powder;
5) Fatigue of the carrier.Change the carrier;
6) Poor cleaning, and do not turn when the brush is turned.The brush panel or hair removal; the scraper has gaps or insufficient pressure; repair the brush box; adjust the combing pine brush or replace the brush;
7) There are too many dust bags.Clean and exchange dust bags.
2. Sensing drum scratching
cause of issue:
1) The charging voltage is too high or the drums are too close to the drums that cause spark breaks;
2) Eye -seeking board (brush panel knot) scratch;
3) If you install it carefully (or incorrectly);
4) Unconscious or improper operation;
5) There are hard objects, such as the hey needle is brought into the copy.
Method of exclusion:
Adjust the distance between the charging voltage or the charging halo and the drum; change the scraper or brush; carefully install as required; operate carefully as required; stop observation of the hard object and change the light drum.
3. Dingying does not run
cause of issue:
1) Diminate the shadow motor;
2) Fuse (fuse) break;
3) The middle roller is not advanced;
4) Transmission gear wear.
Method of exclusion:
Find the cause of damage for maintenance, and you need to change the fixed shadow; re -change the fuse and find out the reason; find out the reason for the promotion; check the motion of the gear communication room and eliminate it.
Common faults of composite machine two
1. Magnetic brushing shaders will not turn
Causes and exclusion methods:
1) Too many carriers.Adjust the carrier;
2) Daiming gear wear.Change the gear;
3) The clutch is out of control.Maintain the development clutch.
2. Low -quality quality (magnetic brush)
Causes and exclusion methods:
1) Magnetic ears are not correct.Adjust the magnetic spike;
2) Automatically supply powder out of control.Adjust variable resistors and detectors;
3) The small wheels of the show are not rotating.Change the small wheel.Maintain and change the cover;
4) The shadowing of the show is invalid, causing the drum pollution.
5) Excessive or too low partial pressure.Adjust the appearance of the show to the normal value;
6) The appearance detection device fails.The detection device of the proportion of the dry method to the ink powder;
3. Falling the powder
Causes and exclusion methods:
1) Follow powder motor out of control.Detect the electrode and control circuit.
2) The powder box is not installed.Re -install the powder box.
3) There is a carrier in the powder supplement that does not run the pink roller.Remove the powder to remove the carrier.
Common failure of composite machines
1. Multiple pieces of paper
Causes and exclusion methods:
1) Paper -edged adhesion.Repeatedly rubbing the paper and reinstallation;
2) The friction of paper and carton is too small.Increase friction on both sides of the carton;
3) Anti -paper clothing.Adjust the surface of the paper;
4) The anti -static ability of paper is too poor;
5) The cutting width of the paper is much narrower than the standard size of the carton, and the paper feet do not work;
6) The angle of the paper box pressing the paper is not good.Adjust the angle of the paper box.
2. Continuously entering paper
Causes and exclusion methods:
1) The number control button fails.Check or adjust the number control button;
2) The counting switch fails.Maintenance or exchange;
3) Paper clutch out of control.Make a pawn -in -clutch and control line.
3. The starting line is inconsistent
Causes and exclusion methods:
1) Time controller timing roller clearance is not correct; maintenance controller and time -time roller gap,
2) Paper clutch fails.Make a pawn clutch.
