I have found that I can always get into service mode when an sc is displayed by waiting until the util/counter button works then press meter count then details then the usual s00s01 thing.. never had it fail regardless of the code displayed. the key was waiting until the util/ctr button worked.. it always has @ some point then go in the usual way regardless of code.

tried boot wait for counter key....

Booted up, waited for util/counter key to respond while code C-D251 was displayed checked meter, details then booted down to go into service mode holding util botton down

As soon as enter stop, 0,stop et etc the display for password flashes (along with scanner under glass) a brief moment then goes away back to trouble reset window.

Nothing seems to work. Tried with door open, all the other tricks no success. The scan accelator board is not there but turned on - as is the fax board not there but turned on.

This is a serious glitch in design - this should never be an issue! Should be able to go inot service mode and turn the stuff off!

As far as I recall there is no further need to hold down the util/ctr button once it is responsive.. last I checked anyway.. only need it to get to the meter button.

quick question

Do you mean normal boot, wait for response from util/counter, read meter details then enter stop, 0, etc etc? That just creates double beeps no action.

I guess you mean boot to trouble rest then wait for a response from the util/counter button? Then check meter details etc?

[copytechman]

Interesting. Normal boot (wait for c code etc) etc.. no response.. funny every time i've tried that it works, allows me to get into service mode for exactly one of the reasons stated (turn fax off if on etc etc).. You have me... otherwise its do the trouble reset thing then when the button shows (trouble reset) do s00s01 .. that works for me too... corrupted firmware or something?
Very strange.

Basically its like I can ignore the error code and go into serv mode like normal.. per se anyway..
try pressing the buttons slower maybe?
I know it can be picky about the s00s01 thing when in the details screen.

I took it slow and was able to get into service mode! Thanks

I got a c550 here and after input of characters stop-->00>etcetc it is asking for password. Anyone know the password default?

"When selecting [CE Authentication] under [Enhanced Security] available from Service Mode, authentication by CE password is necessary.

Enter the 8 digits CE password, and touch [END].

Your very welcome! Good luck!

one quick other question

I have a service manual on order but have not got it yet. The FS517 is seen at control panel - but the feed rollers are not firing - output stops at finisher.

No error codes, checked all ops in service mode for fin no errors all clutches, solenoids, motors etc worked.

This sounds really dumb, but I don't even see a sensor anwhere and all I got where these 4 small brackets that go into side of copier - can't see how they would do anything by themslves. What am I missing here?

[copytechman]

Can u show us a pic of what u mean by brackets? theres a whole bridge unit that goes in the middle too I assume paper goes all the way through that to the finisher entrance? Is the finisher type set correctly in serv mode?
Regards!
