C1 error E0749-0003

[Penvy]

After really going thru this C1 I did a full upgrade on the firmware/software V66.04 from the PC.several times

I noticed the led on the DC controller would stay on during the Dcon/rcon flash.

after that restart the C1 would boot up on the display,
and then get a error shutdown.
I restart again and it boots up to the control screen with the "Print warm up"
But I looked at the Dc controller at the led1 on a restart and the LED1 would go into blinking right away.

I cked the err on the svc and it was there
E0749-0003 Error in reboot command and PDL config
This PLD thing on boot? and the LED1 goes into blinking right away.

Any help guys!
D_L_P got me to look into the Firmware side.

Need help
Dc controller board ...........I just dont think that the prob.
its getting a Error sig on startup from somewhere.

Before this really shut down we had jams on the bypass input and ITB
had a few errors due to the jamming.
but restart usually resets this error.

E749? Wow, can't say as though I've ever cam across that one. You truly have a beast of a machine there.
A change detected in the product composition. It sounds like the machine thinks it should have PDL and doesn't, or it has the PDL and no license? PDL= page description language aka PCL, PS, UFRII. Is this a new HDD?
If you can get in service mode can you do a MMI clear? I wish I could help more but I just don't know much on the C1.

What version software did you upgrade from?

[Penvy]

Heres the thing I will ask.
What will stop the C1 from heating up but going into the regular screen
without any error codes other than that E749 the first time only?
starts up fine after that other that "printer warming up"

Doors ok, 24V ok, AC relay kicks in on start up and out on the door open,
Drawer connectors ok, all therm's ok
Its an error before the mach can even warm up but no error shown.




the original software that came shipped for the 06' model
Dc-con 10.06
r-com07.01
bootrom 16.01

The PDL error was before the update.
I Can get into the svc mode
This thing just acts like its in a sleep mode but I went into the Svc mode to
make sure that the network and sleep was the stay off

The HDD really cks out ok and did a full "all" from the PC direct to the lan conn on the C1
showed all the Dl and updates "OK"

This C1 has the decurler and the saddle book with the DARF-1
D_L_P said unplug them and I did and start up got error.
Plug back and start up OK......but no heat.

When it goes into the main screen you can do everything on the settings and all the svc modes.

No errors on startup other that the first time with this PLD error
you restart it and thats gone and will startup without the heaters coming on.

The CPU reset to the latched_err_therm is what I think is not getting reset. there's an error on the startup DC controller (LED1 blinking)before it
even starts to boot.
Bypass assy?
ITB assy

I Know guys this ones a real pain in the ass, but its MY pain in the ass
and you guys have been very helpful to focus this down to just a few things.

What is dcon version now.

[Penvy]

Ill ck right now but its the V66.04 version loaded from the PC with SST version 4.11
and it works to update and really nothing changed on the "Printer warm up"
You can tell right off whan the heaters come on on start up
but the AC relay Does kick in

The protection side of the circuit that is keeping the Dc controller LED1 blinking shows there's and internal error
All the triacs and PWR boards ck good
It would be simple if there was a "short"
there would be an error.

somethings stopping the Dc controller board from reset to"unlatch" the signal to the AC sub board going to the AC relay (triacs) PCB

Its on Pin 1 of IC68 that wont let the "on" to go "high" is my best guess.
I will get right back with that Dcon version

[Penvy]

OK Here we GO
D-con 16.01
rcon 8.01
panel .03
feeder 2.01
sorter 3.02
nib 5.00
sdl-stich 3.03
mn-count 66.04
rui 64.03
bootrom 55.03_c


I/0
rcon P003 110XX111 X= flashing led
Feeder P005 1111X000 X= toggle
P013
P015
P018

Dcon
P028
P030
P035
P040

Hope this helps

You got 16 switches in this machine.
Have you check the manual feed door switch(sw2).
Also the fixing feeder lock switch(sw6).

[SCREWTAPE]

There's a later version now for DCON v21.01.

[Penvy]

The bypass is where we had the big jams in feeding and even took the bypass assy apart to see if anything was broken (flag sensor maybe)

Thats the next thing to do.
BUT you would think that if one of those switches were open or bad
there would be a Error on the startup.

I know the main door switches will cause the AC relay to toggle off and on
when you open/close.

The bypass drawer itself?
the door switch on that assy will shut off the Ac relay
but hey its a start.

The Dc controller board will show all the other errors
but there must be a few that just are not on the software error code.
That would make sense but
it looks as if its on the protection side on the dc controller not the 24V door switch circuit.
this error goes right into the dc controller from the moment you turn "on" the C1

It would be great if it was just a friggin switch
Remember it was running fine untill that jam.
thought it was in the ITB .........

Well hey this has been a real pisser of a fix.
Thanks guys.

Well lets look at the SW2 feed going to J4002 pin 1
the pin1 is 13v to pin 1 J1811

Guess what the AC driver sub pcb that turns on the AC relay (triacs) to the
fuser assy

I will look for the 13v on pin 1 on the Ac driver sub.
But that J4002 is in the loop with the front door
sooooooooooooo just short pin 2 and 4 on J4002 to bypass that loop circuit.

BUT if there is no 13v on pin 1 on J4002 to pin 1 J1811 on the AC sub
that would be the problem
BUT if there IS 13V there well .................hmmmm
