two. The printer does not respond when sending a print job from the software.
There is an HP laser printer. When the laser printer sends a print job from the software, if the printer does not respond, the reasons and inspection methods are as follows:
(1) The power cord is not connected to the printer or the power supply is not connected to the power cord to make it securely connected.
(2) The printer may be suspended and the printer may be restored and woken up in a dormant state using software.
(3) The connection cable between the printer and the computer is not connected properly and the connection cable between the printer and the computer is firmly connected.
(4) The connection cable is defective: The cable can be tested on a normal machine to verify whether there is any fault. If it is proved to be defective, a new cable should be replaced.
(5) The wrong printer is selected in the software to check the printer selection menu of the software to see if the correct printer is selected.
(6) There is no correct printer port configured. Check the software's configuration menu to ensure that the correct printer port is accessed. If the computer used is not a parallel port, make sure that the printer cable is connected to the correct port.
(7) Connect the printer to the converter that is set up incorrectly. Check the converter settings and connect the printer directly to the computer to verify whether there is any problem with the converter.
(8) The printer should be repaired if there is a printer failure.
three. The printed page color is light
A laser printer, the printed page is light in color. The causes of this failure are:
(1) There is no enough toner in the toner cartridge.
Check the amount of toner in the toner cartridge. If it is close to use up, replace the toner cartridge or add toner.
(2) Adequate toner, but the concentration adjustment is too light
Re-adjust the toner concentration so that it is suitable for its thickness.
(3) The photosensitive intensity of the photosensitive drum is not enough
Re-adjust the photosensitive intensity to make the photosensitive sufficient.
(4) The working condition of the photosensitive drum heater is poor
Check the working condition of the photosensitive drum heater to ensure it is working well.
(5) High-voltage electrode wire leaks, low charging voltage
Check whether the high-voltage electrode wire has leakage such as in-connection with the fixing frame. If there is any, insulation should be done.
(6) The installation position of the transfer corona device has changed.
Check whether the installation position of the transfer corona device has changed. If it has changed, the position should be adjusted to ensure that the transfer voltage is sufficient.
Four. Paper jams in the output paper part
A Canon laser printer, no matter whether it prints large or small pieces of paper, will jamm paper in the output paper part. The upper paper box is normal to pick up paper, only one piece of paper is rubbed, while the lower paper box is rubbed with multiple pieces of paper.
When you open the machine to check, you can see that a single piece of paper passes through the two paper jack rollers of the paper conveying component smoothly, but the paper no longer advances, and the lower paper box has multiple pieces of paper stuck at the front paper conveying component and parked there. It means that there is a gap between the paper jam roller of the paper conveying member and the paper conveying roller, and the paper cannot get friction between the paper clamp roller and the paper conveying roller, which causes the paper to stop moving forward. The reason for this phenomenon is that the long-term paper jam occurs, which causes the spring on the paper clamp roller frame of the paper conveying member to deform and loses elasticity, resulting in insufficient paper clamp force of the paper clamp roller, and no friction can occur between the paper and the paper conveying roller. Although the paper can pass through the paper clamp roller smoothly, it cannot continue to move forward.
The paper clamp roller frame was touched with your hand, and it was loose and deformed. Remove the paper clamp roller frame, replace it with a new spring, reinstall it, test the machine to print it, work returns to normal, and troubleshooting.
