Usually just toner dust on the laser lens, you remove the toner and drum and look on top inside for a window about 1/2 inch wide. You wipe that window with a dry cloth, and also check for paper scraps inside or on the drum assembly.

Printed pages have streaks vertically along edge


Sounds like the end seals in the cartridge are bad. Remove the cartridge and see if there is toner built un inside printer. Also look at the drum on the cartridge to see if it has black lines that line up with the pirnt defect you are seeing. Try a new toner cartridge and run about 50 pages through.

Can someone please help me i have just printed off 400 prints with my brother hl 4040CN laser printerits brand new and its now saying my cyan toner has ran out this is impossible i am right in the middle...


Your toner usage will depend upon how much of each color toner is used on each page. (To conserve colors when printing in Black and White only, specify monochrome in your printer setup) <div>I had similar problems when printing publicity flyers. The toner cartridges claim to be good for about 2000 prints each, but I was lucky to get 3 or 400 pages when printing blocks of color. The TN115 cartridges hold significantly more toner, and the cartridges that come with the printer are TINY.</div>

Prints only blank pages


I have a brother MFC 3240C. My Black ink stopped printing(initially printed horizontal faded lines and gradually got worse), the other colors were printing fine. I tried cleaning numerous time( 50 -100 times over 1-2 weeks ). Still no improvement. The way I print now is:
1. I go to Printer Properties
2. Change Media type from "Plain Paper" to "Inkjet Paper".
3. Change Quality to "Photo".

This takes a long time to print 1-2 minutes per page. However, this works for me since this is my Home printer and use it for printing only few pages here are there.

Good Luck

Printing problem


Vertical line is probably scratch in Toner/image drum or one of the erase LED bar lamps is out. Start by replacing the Drum and see if it is better. LED erase lamp assy is more expensive so I hope for you that it is the drum.

Saw this scratched tomer drum on a ton of HP I serviced while in Europe

Cheers!

Printing envelopes on HL4040CN


I just bought a HL-4040CN and all my envelopes wrinkled, regardless of the size, paper thickness or software settings (thin envelope, thick envelope, etc.). Here's how I solved the problem....Open the rear panel and you'll notice a small gray lever on each side, which is probably pointing to "A" on the scale (A, B, Envelope). Move both levers to "Envelope" and close the back panel. The troubleshooting manual says the levers should be moved back to "A" after printing the envelopes, but I left them in the Envelope position and can't see any difference when printing regular or test pages or envelopes, except the envelopes are no longer wrinkled. I called Brother and asked them if there was any reason why the levers can't stay in the Envelope position, and they told me they could be left there if it wasn't negatively affecting other documents. Now, I have a great printer that prints everything without any problems. Hope this helps.
