CANON LBP 2900 Laser Printer not working fixed
I have received CANON LBP 2900 Laser Printer for repair. The complaint was when switching “ON” the printer power light was glowing but it does not pick up the paper for printing. Further discussion with the customer I came to know that he was an engineering student and he has opened the printer for cleaning purpose and after cleaning from inside this symptom occurred.
Most of the time I do not repair in front of the customer. This is because if the equipment is new, I had to learn and may struggle how to open it and this may not be good if the customer sees it. For your information not all equipment can be easily opened.
I turned On the printer and it does not initialize. I had checked the toner cartridge and top cover for proper fitting. These two sections have sensors and if it not fitted properly, the printer will not start for safety purpose. I have also checked the gear system, solenoid coil, the power and the controller PCB and all seems to be good.
When I continued to further check the printer, I found the paper out sensor clip came off. See the photos below:
Once it was fitted back to its original location and powered On, it can initialize and the printer came back to life.
