Problem making copies (not print from my computer)

I suspect the Document Feeder is not aligned properly and light is leaking in. You will need to have a technician in to check the alignment of the scanner to see if it needs to be readjusted. random black lines on edges usually indicate light leaking into the scan area.

I suggest You Go to Official Canon Printer Page For You Canon Problem On Below Canon Page URL:
Copy Has Vertical Black Streaks In Case You Still face Problem and Need Online Assistance Then Please Follow Us For On : Canon Printer Support

Check your flat bed and Document feeder scanning glass need to be clean, if any dot or dust in scanning glass of document feeder it will appear a line, check this points first
1- Check printouts from computer or FAX if it is clean problem in scanning section
2- Check using Copying a blank paper using only Flatbed if it prints without any line its problem from document feeder Scanning glass
So solution is clean the Document feeder scanning glass using wet cloth, note careful about wet cloth switch off the machine and clean it

Hi I have a LG RZ42px11 there are 6 vertical thick black lines running down the middle off the screen, when cold the TV seems OK but if it has been on for around 10mins or on standby the lines stay on screen.

Thanks.

lift the lid ull see a thin **** glass make sure its very very clean

For the line problem, open the doc feeder on top and clean the scanner glass.

For the number key problem. drip a small amount of WD-40 down into the sticking key.

For this kind of problem you need to call the tech support because the printer is already messed up and it is in need of replacement

Hope this help

Does this happen both when copying and printing?
For printing solution, try another toner cartridge.
If lines continue to appear when copying (primarily through the automatic feeder) then lift the auto feeder, and clean the glass -mainly the narrow piece on the left side.

please rate solution :)

I was getting a verticle black line and I had to clean the glass, the long white bar above the glass, and the white and black rollers before my problem was solved.
