I have a DCP-7040 Brother Laser printer. I am getting a lot of black lines when i print. I have tried cleaning the head of drum but that did nothing.


Two likely possibilities:

1. The drum is scratched by particles caught under the drum cleaning blade. Every copier or printer that has a drum leaves a little bit of toner on the drum that didn't get transferred to the paper. A soft plastic blade scrapes off that excess. If a chunk of fused toner or something gets caught under it, it can scrape a groove around the drum, resulting in a black line. Take a close look at the drum for scratches matching the lines you get. The cure is a new drum unit.

2. The fuser roller is scratched. Open up the back of the printer. The fuser is the assembly with labels warning about how hot it is. The final stage of the print process is to press the page between those two hot rollers, melting the toner into the paper. The hot roller is coated with Teflon to prevent pulling toner off the page and laying it back down where it doesn't belong, but like the drum, it can be scratched. You might be able to look for scratches on the hot roller with the help of a strong flashlight and magnifier. If it's scratched, you need a new hot roller or a complete new fuser.

Let us know what you find.

Go video VR4940 VCR video recording has sound but no picture


You can try cleaning the video tape heads. The vcr has 2 different heads. One for audio which is fixed and a drum head for video with 2 heads on it that rotate. The best way to clean them is to take a lint free cloth ad wrap it tightly around your finger. Put some alcohol on the cloth and place it on the drum. Then rotate the drum as you hold your finger against the drum. DO NOT move your finger up and down as you can brake the head off. The other option is to go buy a head cleaning stick. It's a piece of chamie on a plastic tongue depressor. I've cleaned hundreds of them with my finger though. You can clean the whole tape path with the rag. Good Luck.

I would suggest that a label came to be attached to the photorector drum. Unless you can remove this label the problem will continue
