    I have several light areas running in lines down the middle-left side of printer. I spun drum around and tried to clean but it kept putting out more smeared toner. I have tried 3 different toner cartridges at $68 a pop! This is realatively new unit. How does one get warranty service or more accurately how likely will I be to get Samsung to pay for repairs and how quickly, on site???

    This sucks!

Its a problem with the black developer unit inside the opc drum. This ahppens to all the samsung printers. The only way to fix it is to change the black developer and to upgrade the firmware.

Hi, On another Samsung model (ML1610), I tried shaking the toner cartridge left & right (presumably to evenly distribute the powder inside). On another instance, it was caused by a replacement cartridge (not original) and then again was when I tried simply refilling the old original cartridge. In all cases, the drum (which was inside the cartridge assembly)had to be cleaned, or the cartridge replaced (with original). The most tedious was when I had to open the cartridge and remove the replacement toner that has formed into solid lumps. Hope this be of some help. Pls post again how things turn up. Good luck and kind regards.

    If I may add, if replacing with an original cartridge assembly and cleaning the drum doesn't correct the problem, it is possible that you may have a heater problem, (uneven heat, smeared glass, something is lodged between the heater and the center area of the paper). If this is the case, then you would need a qualified service professional to open it up and check the inside. I will not recommend that you do it yourself not unless you are confident working with tools and don't mind getting yourself black sooth all over. Cheers.

It prints only half a page.... how can i fix that???

Does the print fade out or is the printed page complete, just cropped down? If it is fading out then it is the cartridges running dry, or refilled using the incorrect ink. If it is printing the entire document, just smaller, then under printer properties you can set the page size. (control panel - printers and faxes - right click your printer and select printing preferences) I hope this helps Regards GM

I do not know what kind of copier you have but lines (when you run thru the feeder) are usually caused by something on the glass under the feeder. If you open the top, you should see the big piece of glass and also a piece about an inch or two wide next to the big one. Look closely at the smaller glass for any spots on it. A spot will show up as a line on the copy. You can use windex to clean it.

Problem with Canon MX700 printer: For the past

Look inside at the clear strip that runs across behind the carriage. With a light you should see grease or ink spots at the same area where the skips appear on your page. Clean the spots off with a Q-tip damp with alcohol.

Model 7700 won't allow me to run printed page through for two-sided print. Shows jam warning, but no jam. Unprinted pages run fine.

Are you using the bypass tray for the second run? If so, of course you have a problem with the bypass paper path. As you might know, the workaround is to place the printed page face down on top of the paper stack in the input tray. . I would be amazed that if you tried to run it this way (page on stack) that the machine would cough it up. That would amaze me. Try running sparcely printed stuff through, stuff printed on only one side of the page, then the other, then the center, etc. Could be that there is some sensor in there that doesn't like black toner marks just to see what is going on. Then go from there by asking online with that info. . Good luck.

Reference page 22-17 in reguards to cleaning the charge wire on the drum unit and page 22-16 for cleaning the document scanner. This is a link to your Brother MFC 8500. Hope this helps.
If the dark streak appears on printed documents, cleaning the charge wire will correct it.
