rsolomon Posted October 14, 2006 Share #1 Posted October 14, 2006 Advertisement (gone after registration) my sensor could use a cleaning - but honestly i'm afraid to do it. The camera is perfroming well, but very recently i have discovered a "black spot" so i am assuming the senor needs to be cleaned. i have owned the DMR since it first came out . i have had no reason to clean it until now and don't beleive in cleaning lenses (or sesnors) until required. i rarely take a cloth to my lenses. i have read the DMR manual requiring a photsol type 3 senor swap. the directions look pretty straight forward. is there anything special to watch for ? to be careful of ? do i clean the senor or just wipe over the glass cover? are there any detail instructions provided by leica for this ? thanks Link to post Share on other sites More sharing options...

Guest guy_mancuso Posted October 14, 2006 Share #2 Posted October 14, 2006 Richard i use Eclipse and sensor swaps . i put a little Eclipse on the sensor swap and go in one direction than maybe do it again. Try not to oversoak the swap and get the FF swaps it covers it entirely and really that is it. I also use canned air after that everyone and there brother tells you not to do but i am just careful Link to post Share on other sites More sharing options...
rsolomon Posted October 14, 2006 Author Share #3 Posted October 14, 2006 Guy, does this mean you just remove the bottom plate, open the door and apply to the thin glass layer over the sensor. i was thinking that the think glass layer had to be removed to get to the sensor ?

Guest guy_mancuso Posted October 14, 2006 Share #4 Posted October 14, 2006 NO NO NO do not remove any glass. Just open the back . Need to take motor off than open and just clean that. Link to post Share on other sites More sharing options...
rsolomon Posted October 14, 2006 Author Share #5 Posted October 14, 2006 thanks !! just wanted to confirm -- i guess it is pretty easy then. but one question. am i really cleaning the sensor or just cleaning the glass layer on top. ? Link to post Share on other sites More sharing options...
Guest guy_mancuso Posted October 14, 2006 Share #6 Posted October 14, 2006 Your really cleaning the protective glass. I believe they actually seal the glass to the sensor so nothing can actually be on the sensor itself. I do think the glass is Infared coated. Link to post Share on other sites More sharing options...
dezeufr Posted October 14, 2006 Share #7 Posted October 14, 2006 Advertisement (gone after registration) Open the DMR back and blow air on the sensor to start with. Don't use chemicals or contact materials if it's not necessary. Use a product like the one in the attached link: hama.de | Abbildung: 00005610 Blasebalg "Dust Ex" Link to post Share on other sites More sharing options...

kobold Posted October 15, 2006 Share #9 Posted October 15, 2006 In Australia at the R9/DMR launch, when the same question was posed, the tech opened the DMR back, whipped out the tail of his shirt, and went to work. Following this somewhat dramaic display, images were made and inspected. Images looked perfect. Different to the Canons and Nikons, the sensor and protective glass are 100% accessible directly when the back is open. He was just trying to make a point that, in the field, you don't need to be especially careful. Link to post Share on other sites More sharing options...
gogopix Posted October 15, 2006 Share #10 Posted October 15, 2006 Depends on whether you wear your shirt tail in or out. Link to post Share on other sites More sharing options...
Guest rubidium Posted October 16, 2006 Share #11 Posted October 16, 2006 I always try Dust-Off or something equivalent on optical components first before resorting to any liquid-soaked wipes. But make sure it's intended for optics. Other compressed gases in cans for dust removal (like the cheap stuff sold in computer stores for cleaning keyboards) often "spit" liquid out of the nozzle, which leaves a nasty residue on optics.
