November 2010 Subject: KM 3035 w/job finisher Question: In the field, the machine will sometimes say “Remove paper from Job Separator, Offline” even with only 12 pages, more or less. Now, when it’s in the shop it seems to be fine. Any ideas?? How does it know when it’s full?? By count or PI sensor? Answer: If I remember correctly there is an eye sensor that gets dusty. Question: Thanks. Maybe that’s why it works in the shop. I had cleaned the black felt at the exit before installing our copier. Is this like the exit felt on the DC3055 feeder? They used to get paper-dusty and cause grief. Thanks. Answer: Also check their wall for power fluctuations. Have seen it wreak havoc with other optical type sensors. Answer: Yes. Agree with above posts and also watch for sunlight coming through windows. Had a problem like that on a Canon years ago. Customer called me back like 3 times in a week. Every time I got there, it was working fine. Finally narrowed it down because it only happened in the am and the copier was by east window. Question: Thanks. I’m trying a reinstall today, sale pending. Have a good weekend and I’m going flying, maybe even my first SOLO. Question: Installation went great. No more problems after lots of testing. IT department is happy and I just need a signature and it’s sold. SOLO went great, good landings, good flying; it’s so fun and relaxing. I’m glad that we techs still have work so we can afford to do things. Life is good. Answer: I have also had to take a Black Sharpie and color the felt pad to darken it up. This has worked great. Subject: Copystar 2014 1/2” black band Question: Does anyone know a fix for the Copystar 2014 that makes a 1/2” black band on the paper from the front end of the drum? I’ve tried replacing the drum, the blade and the developer. This didn’t fix it and was very expensive. Any ideas? Thanks. Answer: When you pull the drum unit, is the black band on the drum cylinder? If so, if you rotate the drum does the blade clean the black mark of toner off? If it cleans it off, I would check if there is a bad erase lamp. Is it solid black or just heavy background? And lastly, how wide is the band and is it at the edge of the paper? If it’s heavy background, clean all optics and both sides of the drum filter glass (which isn’t easy or fun). Oh, and check the corona wires and gently clean them if there is toner on the wires with a q-tip and isopropyl. Question: The ink is on the drum and is very thick and you have to clean it off with alcohol. The line is actually 1 1/2” wide and when you stand in front of the copier, the band is in the front. Thanks Answer: So, the drum-cleaning blade is not cleaning it off if you rotate it by hand, correct? Question: Yes that’s correct and it’s a real common problem I’m having. I’m even using OEM toner. Any ideas? Answer: It should be simple enough to find out why. Will the toner wipe right off with a soft cloth or is it that hard residue that blackens the drum and takes alcohol and a lot of elbow grease to clean it off? If it comes off easily, either the blade isn’t contacting that area or maybe the blade is up against the red felt on the drum unit. I’m not looking at one right now, but I think I had to move that felt and the blade went under. For the hard residue, there could be a cooling fan not working and it gets too hot near the fuser, melting the toner to the drum.  Subject: Sharp AR M277 paper jams Question: Sharp AR M277 constantly jams from the upper cassette. I replaced the feed rollers, but the problem seems to be the jam sensor. I have tried letter size paper each way, and 8.5 x 5.5, and the copier still jams. The statement size paper has passed the registration roller. The lead edge is normally right at the top of the fuser rollers when it jams. The lower cassette is fine. Has anyone ever had this problem? Thanks for the help. Answer: I know you said you replaced the feed tire, but did you replace the separation pad as well? Just to be sure, you replaced the feed tire under the plate that is held in by three screws? Answer: Is the paper tray setting set to the correct size? Did you put the roller in correctly? How many feeds are on that tray? You may need a new clutch. What is the error code you are getting on the 22-6 printout? Answer: Have you updated the separation pad assembly? Answer: I had this problem about a week ago. The customer pulled a jam out too hard and broke the tip of the flag so now the flag is too little for the paper to hit, so it throws a jam. When you remove it it’s gone because it was never hit. Tips appearing in this section are reprinted courtesy of Smarka! The Copier Tech’s Info Source.
