How can I clean up the internal parts of my Samsung laser printer ML-1665? The printer was ok, but after stopping to use it for quite too long, it started smudging paper. I thought it was the toner, so I replaced it with another brand new, original unit. Since then printing is way better, but some spots still remain, see pictures below. I think the damaged toner just leaked to the printer and now I need to find the right pieces that need a cleanup.

Replacing the drum seems an alternative, but what is the drum exactly? Is it available from Samsung for this old model? How can I replace it myself, in case I go for this option?

That is a pretty specific question for a specific printer, your best bet is to contact Samsung Printer tech support, or post on their forums. Because unless there's someone here that's an expert at printer repair, and knows samsung specifically, I doubt you'll get an answer. 2ndly when a printer starts to leak ink, its time for a new printer, the time and effort that goes into repairing or figuring out the problem is not worth it $$ wise. thats my 2 cents. gl –  Sickest Sep 14 '13 at 21:05

Not necessarily, the model is there just as information. Maybe there are general principles or tips that I'm unaware of, so any guy with experience on printer maintenance, not necessarily with my model, could help. And I hope so since I have spent some money already for the new toner, and selling whole printer with this problem would be hard. –  Renato Silva Sep 14 '13 at 21:09

@Sickest Everyone person asking a question on SU has a "specific device" but we can all offer general advice. This problem is not specific to this printer, or even this model. –  Moses Sep 14 '13 at 21:45
    
Samsung gives some nice pictures of typical printing problems. For horizontal lines they give as possible causes: (i.) The toner cartridge may be installed improperly. Remove the cartridge and reinsert it. (ii.) The toner cartridge may be defective. Remove the toner cartridge and install a new one. (iii.) If the problem persists, the machine may require repair. Contact a service representative. –  mpy Sep 14 '13 at 22:49
    
@mpy, I tried reinstalling toner already, and bought new, original one. That seems just random from them. I recently spent about a week trying to make a crazy HP wireless printer work, and they had no idea what to do. Toner leaked to the printer from the old cartridge, that's pretty the fact. Paying Samsung to fix it may be more expensive than a new printer itself. Instead, I want help for disassembling it and/or finding out the culprit, so I can take care of the proper cleanup myself. Thanks for the diameter tip below though, I plan to check this later. –  Renato Silva Sep 15 '13 at 6:53

I have had toner explode/spill all over printers all the time, it's a pain! My recommendation is to use a vacuum with a hose. It's probably not a supported method but I've had pretty good success with my shopvac. Also, tissues which are designed to pick up and keep small particulates make the best cleaning rag in my opinion.

I would look up the repair manual online, disassemble the printer (make sure you can put it back together again), vacuum and wipe everything down with tissues. It's a lot cheaper than a new printer or paying for a repair man to come out and replace all the parts that are just a little dirty.

To answer a few of your other questions: A drum is the part of the printer that transforms the image to be printed from the laser to the paper. It's basically a specially coated cylinder that the paper wraps around and receives its image from. Replacing the drum is not always a viable option since in some cases it's not meant to be user replaceable and on a printer as old as yours I couldn’t find any for sale in my 30 seconds of searching.

Good luck.

Just one detail: If you spill a lot of toner then do not vacuum clean it. I small fill can be vacuumed into a bag using vacuum cleaner (preferably one which is already partially filled), but most toner consists of such small particles that they will pass though the bag and into the vacuum cleaners electric engine and the filtered air outlet. What I saw in the pictures certainly classifies as 'a little' bit of toner, but I wanted to have this warning mentioned. –  Hennes Sep 28 '13 at 20:34
