FREE TECH HELP Subject: e-Studio 720 runs REALLY slow... Question: I swear, sometimes I get the REAL winners. This machine was installed about 3 months ago, fully PM’ed and serviced. Has only about 200K on it and all firmware is ver. 345. The other day, it starts jamming on the customer. The initial jam code is EAE0, so we pull the Finisher and the machine seems to run fine, except REALLY, REALLY SLOW at about 25 copies per minute instead of 72 (??!!). (Quick note: when it had the Finisher on it, it would take way too long keeping paper in the finisher’s buckle chute before trying to exit it out so we feel that the machine’s extremely slow speed was causing the jam in the first place. Hope this makes sense). We were advised to replace the RAM and then the System Board. Tried both, neither worked. Have you guys any other ideas ‘cause I’m scratchin’ my (gettin’ balder) head... Could the Logic board cause this? Power Supply maybe? Thanks in advance. Answer: Boy, you got a strange one there. I just woke up and am waiting for my coffee to finish dripping so excuse me if I don’t sound brilliant. Just off the top of my head I would think if the paper traveling through its course were to move too slowly in the paper feed section, then you would get a jam code before it reaches the drum. Since the paper does exit and only jams when it gets to the finisher then somewhere between the drum and finisher entrance is where the slowdown is detected. That kind of makes me think the exit or reverse motors. I would think multiple copies would throw a jam code if that were the case though (I’m thinking while typing here). First I would measure the wall voltage and make sure you’re not operating on low voltage (I doubt the machine would work at all if you were, but still better to check it). Then run all the motors individually and see if they sound like they are running at their proper speed. If you cannot tell, then measure the input voltages to the individual motors and see if it IS the power supply. The firmware version for the 720 is up to 352 now but it only changes printing and coin-op issues. I doubt it would help upgrading it. If I were to just blindly guess I would say it is probably the power supply, a faulty motor, or the logic board ... in that order of probability. Try to test the power supply, the individual motors, and then take a shot at the logic board. That’s the route I’d take, but I’ve never seen that issue so this is just my best recommendation. Answer: Now I am trying to get flamed so hear me out!! Check the paper settings and see if they changed the paper type to thick 2 or 3. This will slow the machine down to about half speed. Also check the finisher entrance sensor. I had set them be slow to return, causing the jams you are getting. I also thought (may be wrong machine too many to keep track of) when there is no finisher installed it slowed down because of the “catch tray.”

Question: With finisher removed, still VERY, VERY slow. Looked at paper size settings on panel, not set to Thick modes. Answer: Then the only thing I can think of is wall power, power supply, logic, logic nvram. Answer: Does machine have an external LCf and if not, try reformatting hard drive.
Subject: Sharp al-1651cs L1-00 code Question: I try to reset by #*c* 14 but didn’t work. It seems to be a scanner problem because expo lamp didn’t turn on and scanner just moved a bit forward then back to home position. Which sim code can I use to test the scanner motor? If it is a problem with the scanner motor, is it same as AL-1631? Any info? Thanks. Answer: Physically remove the scanner lock or check for tape sticking to bottom side of scanner. Answer: Is the scanner lock off or even better removed? Question: Scanner lock is in the off position, I already checked it. Any other ideas? Thanks Answer: Clean & lube the rail Answer: Clean & lube rail is correct in many cases but you often MUST remove the rail and clean it outside the machine. I don’t know why but I have had it work about 3-4 times when cleaning inside the machine did not help. Question: I once had a service case when it helped to clean and lube the rail. But this case didn’t apply so far. I only cleaned inside the machine, so maybe I will try to clean outside the machine next week. Thank you for the help. Answer: Once you take the rail out, be sure to clean the scanner bushings as well.
Subject: CopyStar CS-5035, C6000 error Question: Can anyone please tell me what the C6000 error code is for CopyStar CS-5035 and how you clear it? Thanks... Answer: You have a bad fuser assy? Turning it off and on will clear the code. But if it comes back then you need to call a tech for this repair. It is not something you can do if you don’t know the machine. If it requires a screwdriver then forget it. It’s going to be about $400-$500. Good luck. Question: That’s all I need. I’ll check the fusing unit.
