Subject: Aficio 2060

Question: An Aficio 2060 with sc495-toner recycle error. The waste toner bottle is nowhere near full. I considered taking the assembly apart, but access is a nightmare. Any ideas? Answer: Replace drive pulley (AB03 0458 Pulley - 28Z) if the toner collection coil is clogged. If the toner collection coil sensor is unplugged, replace both push switches on the bottom toner recycling system, which is above the paper feed unit. Answer: Pull the recycling unit from the rear of the machine and clean the sensor and the toner which is packed into the tubes keeping the auger from turning freely. Answer: Usually it is the sensor at the top of the waste toner auger (back of the machine) that monitors it turning is covered with dust. If you think about it you realize that charged toner is going through this auger making the unit into an amazing dust magnet. I can’t help but wonder then why we would use a photo interrupter in an assembly such as this. Answer: It was probably designed by the same people who put a photo sensor in the top of the waste bottles on the older IR series of Canon. GOOD thinking there boys!! Question: I replaced both sensors, problem solved. Thanks guys.

Subject: Xerox M20

Question: Light copies but prints look good. Customer loves the machine and wants it repaired. Cleaned the optics—a no go. I’m getting ready to order a laser-scanner unit. If anybody wants to stop me with another suggestion I would appreciate it! Thanks in advance. Answer: Did you try taking apart the scanner assembly and clean the mirrors inside of it. There are several mirrors inside and it does come apart. Answer: I might be thinking of the 5530 (Samsung 5115 or 6320 is same as M-20) but as I recall, I tried disassembly and got real nervous because of those exceedingly flimsy, fragile lamps. You can probably get a good used CCD/CIS from Parts Drop if you do break it. Answer: If the prints and reports are good it is not the LSU. This is a SCX6320. Not to sound stupid but is the toner save mode on? I would say get a new CCD-scan unit if anything. They often do not survive tear down for cleaning. Did you tear it down or just clean the #1 mirror? Question: I just cleaned the #1 mirror I could access. As I stated prints look good; only copies are an issue. Don’t want to risk ripping open the scanner unit and the customer is willing to buy whatever it takes to fix it. This being the case, what would you guys go with? Answer: The scanner unit has little slots around the sides—put a small screwdriver in the slots and turn, and the whole top will pop off. It will still be connected with wires but you can access the lens and mirrors. Never broke a bulb on one. Answer: Depending on the status contract, I would have a spare “ELA HOU-CCD MODULE JC96-02759B” on hand. Tear down the one in the machine and clean it. If it broke I would change with the new one. About 1 out of 10 breaks. I would change the unit and clean the old one for spare emergency. The part number for Samsung is most likely the same part number on Xerox. If the scanner tears off, it is NOT as hard as you may think. The real important part is do not damage the flat ribbon as in all machines these days. I can tear one down and clean and install in about 15 mins. I would get the book. Answer: If you’re already at the buy point, what’s the risk? Tell them, you’ll try, with no guarantee. I’ve cleaned a number of them. Just take off the holders for #2/3 mirrors and that gets you in with a q-tip. Ozone has probably got them fogged up. Charge for every second of labor! Answer: If you don’t feel comfortable tearing the scanner apart, try doing a shading adjustment in TECH mode. I have had pretty good success with light copies just doing a normal scanner cleaning and then going into tech mode and doing the shading adjustment. Answer: I just cleaned one. Do them every so often. On this one I saw a plastic part fell off. I put it back together and the sides of the copies have blank and black streaks. 2 more times apart and I used black tape over the side and rear clip and cutout holes and slots. Almost perfect. Don’t know why this time it was so much trouble. Make sure you have the time in case. This time I didn’t, so it made it worse. Customer hit with extra 30 minutes for the trouble. Good luck. Answer: I mentioned this before and got this from someone else here. If you can’t get it running with the shading adjustment from a white sheet, do it with a black or dark sheet on the glass; it will give a much darker copy. Question: Thanks for all the tips guys. I’m ordering the unit today but will attempt a cleaning before replacement.
