Need Help with Sharp SF-2027

[AmateurCopyTech]

Hello, everyone.

Today I found a great deal ($30) on a working Sharp SF-2027 copier at a Goodwill.

In the store, I put in some paper, and successfully copied.

However, once I got it home -- now the copy machine turns on, and everything looks and sounds like its working -- except when I push the Copy button, nothing happens, no response.

On the LED where the # of copies should be there is a "CH" code.

I fear that the move may have done in the copy machine for good -- it was difficult (the thing is heavy!).

Does anyone know what is wrong, and how I could fix it?

Also, is there a way to get the manual for the copy machine for free? I saw a service on here that offers it for $11.00 -- but I am running a tight amateur budget here.

Any tips are most appreciated.

So....... Just what we've been talking about tonight. You picked up a copier machine for cheap and now you want a FREE service manual to fix it.
Well, here's the score, you're taking food out of the mouths of the local copier technician who could probably fix it in a jiff, but you want to do it yourself. Tell me, when you go to a lawyer, do you ask for his law books to see if maybe you could do his work too. How about your car repair, do you pick the mechanic's brain when he's working on your car for some secret tips that he has accumulated over the years so you can save a nickel?
So, here in your first and most likely only post, you're asking for a FREE service manual. Why should someone give you a service manual? It's not like you're ever going to return the favor, or even ever come back here if it turns out that even with the manual you're too much of an arrogant asshole to figure things out.
I sell service manuals for a living. I am disabled and by doing this I can stay somewhat in the trade and still support myself. I give away many manuals every month to people who are deserving of them and former customer's, and in general to folks I like, not an undeserving cheap putz like you!

Too bad..

I look for free services and products because I am poor --- due to caring for my mother who is currently in the hospital.

I have also spent all of my last few years' free money preserving a progressive educational project that could seriously help the world out of it's current illness and confusion.

That is why I purchased the copier.

So I ask for free services. And sadly, like so many others, the genuine who scratch together all they can while the world takes and takes from them, must suffer under the worst accusations from the very people who could help them.

I hold no grudge tho, and I am glad that you have found a way to make a little cash in a vicious economy.

My copier still does not work, however. And I may not even need the manual. But I do need help, and so I asked.

Well, I would look to make certain that you have all doors properly closed, make certain the developer unit has not slid out, where the toner box is attached to.
Don't let comments from some deter you....I don't know of many stores or shops that still work on analog machines. As for manuals, $11 isn't a whole lot to pay.

[Smurkey]

you have a panel open somewhere, even just a little bit, or you damaged one of the sensors in transit, check all the panels for it and make sure they are all closed.

I still have a couple analog machines kicking around town i have to work on, just had a lady bring in a sf-2214 yesterday..

and paul, the whole point in this buisness is to help people, this forum is meant for helping others who are having problems, and passing on knowledge that one of us may hold. we all join this forum willingly and choosing to give out your knowledge is willing. and disabled you may be, i found your post tearing someone down very offensive. considering you probably get a disability pension and are no longer in the service industry would it not be better to pass on the knowledge you hold? and i realise you make some money off selling the manuals, but what is 1 person in the 6 billion in the world? if you don't like a post don't reply

Hi Taylor, I can tell you this guy sucks, always jumping on everybody: read this thread.

CH = door open (3 possibilities)

Yes, most likely it's just a door open, or a doorswitch actuator that may have been broken in transit. The doorswitches themselves rarely fail.

These sort of discussions trouble me. I try not to dignify the participants by responding to unkind words, and unduly harsh comments. I would have to say that is the only major criticism I have of this forum.

=^..^=

You definately have a panel open. If the developer unit were pulled out you would get a flashing CH. If you strapped the front door too tightly you may have bent the actuator on the front door. It is located on the upper left side. You can easily bend it back out. Good luck. (oh, that will be $150.00 dollars please.) JUST KIDDING!
Everyone wants to make money and there are plenty of machines that have and will have issues. There will also always be a need for people to buy manuals. Sometimes some people want to help others because it can feel rewarding. Maybe, if I dare say, give away a manual or two. I thought this website was for sharing information for free. You can choose what you want to share and with who you want to share it with without having to deal with getting crap from someone who wants to make a buck. I do not care what your situation is and I do not want you to care about mine. If you have something useful to share then share it or just shut up.

[chakiris]

you need to check the left exit panel if the actuator is not broken when you open and close this panel.

[AmateurCopyTech]

It Works.. But..

Thank you everyone for your help -- the copier is now working, basically.

The problem creating the "CH" message ended up this little switch on the bottom of the paper sorter that is attached to the side of the copier.

When the tray is slid up the copy machine, it clicks on.

Now the problem is, that tray had to be moved around and taken off when I was transporting the copy machine -- and the rails on one side are a little bent around -- so it doesn't slide smoothly up to the machine.

So I have not yet been able to get the paper to slide smoothly into the tray -- which ends up giving me a minor paper jam error on that side after each copy -- which goes away easily when i remove the paper and the open and shut the front panel.

What I ended up trying too was putting an eraser on the switch that needs to be clicked, to click it artificially --- which works -- so that the copy can just fall freely out of the machine.

However, even though the paper doesn't touch anything -- it still gives me a paper jam error after every copy -- and I need to turn the machine on and off to get rid of the error.

Is there another sensor in the feed tray of the paper sorter on the side that is triggered when the copy comes out of the machine?

I may be able to rig up the paper sorter again -- I'm just not sure exactly how that metal sheet that sticks out of it aligns with the machine so that the paper feeds in. Probably just need some experimentation -- but any help would again be most appreciated.

Hi What poeple are saying is right it is one of the interlock switches bent or the plastic actuator is snaped off if you want to work on old equipment and make a buck thats fine by me if you need a manual give me your email and i will try to send you a copy

The reason you are getting paper jam indications even though you have the sorter pulled back is beause the sorter is still plugged into the machine. Make certain it is unplugged and you should be able to make copies.

[blackcat4866]

Machines of this era are not plug & play. The machine must be told what accessories it has then it looks for them. If you remove an accessory that it is configured to have, the machine concludes that that accessory is somehow inoperative.

The way I see it you have two options:

1) You can take some digital photos and attach them to the post, and I'll dredge up wht memories I have about the alignment.

2) You can configure the machine to function without the finisher, and remove it. In simulation 26 there is a submenu called "Options". There will be displayed a number. This number reflects the combination of accessories. For example the RADF (document feeder) is worth X
A cassette base is worth X
A sorter is worth X
'0' value means that the accessory is not present.

The sum total of these numbers = the number displayed. So you need to select the Options submenu, determine the current setting, then subtract the value associated with the sorter, then press start.

Here's the problem. I haven't had a manual for an SF2027 in years, and I don't know the numerical value for the sorter (I think it's '4', but I'm not at all sure). The values range from 1 to 8, so there is a fairly small number of guesses required.

So here are the steps:
Enter Service Mode: C, interrupt, 0, interrupt. Use numbers keypad to enter 26, then Start. I think you can browse to the next submenu with the exposure keys. When Options is highlighted press Start. The current number will be displayed. Enter the new value, then Start to lock it in. I think Reset several times will exit from service mode. Then test the various accessories for function.

Definitely get the manual. As you can see, my memory is not all that clear. And the manual will provide you with the numerical values for the accessories.

[chakiris]

We have the same analysis with blackcat. If you try to disable the sorter and try to make copies and see if there still a jam after each copy. If there is, then the fault maybe is in your exit actuator which won't swing back after a paper passes in it thus causing a paper jam indicator....You have to clean the actuator and put a little drop of silicon oil to make it move freely.
I think you still need a manual to simulate the optional accessories....
