Subject: Canon IR6570 E002-0010

Question: I have an error code E002-0010 on a Canon IR6570. What is this code? Answer: The power was turned off without resetting an error code. Check the last error in the log before this code and correct that problem. Answer: Huh? That’s a fuser heating code. The fuser didn’t reach 150 15 seconds after it hit 110. Try cleaning the thermistor. It might also be the connector on the rear of the unit; try shimming the connector by placing a small washer behind each screw. Answer: Had a similar situation with a 5570; the fuser had drive gears on both ends of the roller. Make sure there is not a crack in one of the gears. There are timing sensors on the gears which will throw a code. Answer: The sensor will throw an E840 code. Question: Thanks to all that responded. The machine is located in an old Reformatory with areas of very old wiring. Even though they tell me it is on a dedicated line, I do not trust the wiring. I reset the error code and have waited several days with no failure. So far so good.

Subject: KM di5510 light copies

Question: Copies are under-toned after changing out drum blade. I put machine in 36 mode (blade adjust) and it toned up a little. Copier is 60k away from PM. This copier is the only one like it that I work on. Answer: Clean the sensors under the drum blade and clean the coronas and do the peculiarity adjustments on all of them. If not you will have to replace dev and then do them. Question: Thanks for your help. Answer: Is your DV unit turning? Check and make sure no gears are stripped out. Question: Cleaned coronas and reset all peculiarity settings and it works great. Thanks. Answer: You probably didn’t have the charge corona sitting right. It can look like it is seated properly but it is not. Anyway glad it is fixed.

Subject: Toshiba MR-3018 DF question

Question: I have a document feeder on an ES281C that jams on every 5th sheet. One sheet is fine, two sheets is fine ... 5 sheets and you’re screwed. Paper exits, none in DF paper path, then jam code E724 (registration sensor staying high). Normally this would be the sensor itself, so I replaced it along with the read sensor. Did not fix the issue. Now I am pretty certain my 5v isn’t right. Probably set too high and I need to adjust it. I have made this adjustment once before but cannot remember how to do it. My question is simple. Which connector and pin do I measure off of and more importantly which of the two POT’s on the PSU do I turn? I think it’s the one on the left, but again I don’t remember. Answer: I had a similar problem on an E-studio 3500C. I’m not sure if this will help but check CN 70 Pin 2 on RADF board. Voltage should be between 4.95 and 5.25 VDC if not adjust VR2 on the LVPS to 5 VDC. Monitor while adjusting at CN 404 pin 1 on LVPS. Question: Thanks. We are definitely on the same page, only I am leery that the 3500 has different pin outs than the 281C and I don’t want to go twisting POTs I’m not sure about. Answer: I found my service manual on the 281C and checked the Output channel page. CN467 pins 21 and 22 provide an output voltage to the RADF of 5.1 V. Question: Thanks, I appreciate that. Didn’t have my handbook with me. Question: Ah, ok I got it. Actually CN467 pins 21 and 22 are the 5.1 V output to the SLG board. Output to the RADF is pins 5 and 6. The trimmer pot I need to adjust is the one on the left. I’ll be back out to the account tomorrow and I will post a follow up as to whether the adjustment fixes my problem or not. Answer: I’ll have to double check my manual again. Sorry if I gave you incorrect info. Question: Thought I’d follow up: I had to borrow a meter because I left mine at home so I got one from a co-worker. I get to the account and measure the 5.1VDC and I’m getting 6.12VDC, according to the POS meter. I’m thinking, dang ... that’s too high. I turn it down to the 5.1VDC like it is supposed to be and then when I turned on the machine I got nothing but fans. No panel, no warm up ... just fans. I knew then the stupid meter was off but I didn’t have a clue by how much or which direction. I figured the symptom called for more voltage and not less so I turned it up to 6.25VDC according to the POS meter. Turned the machine on and it fired up perfectly. Ran a bunch of jobs through the DF and not a single jam. I made it jam on purpose to see if the jam signal would clear like it is supposed to and it did. Case closed, machine fixed. Moral of the story ... if you are doing this type of adjustment don’t borrow a meter. Use one that you know is calibrated right.
