Canon IR3300i Top Feeder Not Being Recognized

[teckat]

Teckat, red is showing 53.1V.

do u have meter set for VDC/ is there a push button circuit breaker on that DADF board ?

Try and go from the J2 24v red wire to a blue ground wire on J1

Guys, I've compared the 7 pin connector from the pigtail interface cable coming from the reader controller PCB and have the following values:

● readings from problematic IR3300i
purple: 0V
black: 10V
yellow: 0V
gray: 0V
white: 0V
red: 53.1V
blue: 0V

● working IR3300i readings:
Purple 0V
Black 10V
Yellow 9.9V
Gray 10V
White 0V
Red 53.3V
Blue 0V

2 wires are dead - 0V on the problem IR3300i. If the reader controller PCB is the problem, then if the reader controller board is replaced, is there any adjustments that would have to be reinputted once a replacement board is installed?

Might a RCon clear or software glich restore power to the 2 dead pins, or is this a clear circuit board failure?

Thank you.

i will bet your meter is set for AC instead of DC

when u measure these voltages whaat ground are u using / a Metal(frame) machine Ground or from a blue Ground wire on a connector

Blue- is a ground wire 0 =normal
Purple- supply may be an active low/so 0v is OK !/when DF is running voltage is probably supplied then.
Red- is usually 24v
Yellow & Grey= are signal supply wires
White -??
Black-??

Teckat, was using AC reading on tester. The DC tester reading voltages are along what you are desribing the 5V & 24V settings. The black & gray on working unit's 7 pin connector are at 5V, whilst the yellow is at 4.8V. The problem unit is showing yellow & gray as dead - 0V.

Might this be possibly software related (i.e. RCon issue) or definitely a reader controller PCB hardware failure? Will be doing RCon clear & recalibration.

Thank you for your clarifying posts.

Thank you.

yellow & gray are 5vdc communication supply / have u tried or can u try swapping boards..

[dbmoylan@gmail.com]

Am attempting since yesterday to source a reader controller board to swap & test. Will try RCon and see if any change.

If the reader controller PCB is changed out, would any settings have to be initialized or reinputted? Thank you!

Are u talking about the READER CONTROLLER which is in the READER PART
or the DADF CONTROLLER / both need settings put back in/ I sent u the ones for the READER(RCON) in an e-mail

voltages u were testing were on DADF CONTROLLER

[dbmoylan@gmail.com]

Teckat, I understood that the voltages on the 7 pin connector were coming from the reader controller & that the DC controller is the top circuit board that the 7 pin connector plugs into.

Can you please clarify where (which circuit board) those 5V & 24V are coming from? I suspect that it's that circuit board that may have a problem given the 2 dead readings on the 7 pin connector. Thanks.

Curious development. Overnight the DADF green light started to light up when a paper was placed into the feeder. Also, the gray wire is now reading 5V. However, the yellow wire is still 0V. Tried restarting but no additional corrections.

I will be doing the RCon now to see what might change.

Go for it!

JI & J2 are on the DADF DC CONTROLLER PCB ASSEMBLY/
Power to those two connectors comes from Printer

Sometimes when u push a meter lead in a wire connector u could blindly repair a loose connection that way.

The Reader B1 houses the Scanner Unit/in there is the >
The Reader Controller PCB; = it controls the reader unit, & controls the DADF communication

[dbmoylan@gmail.com]

Teckat, have done the Rcon and no change. Further, after having restarted the unit, the DADF is no longer having its light go on when placing a paper in the DADF. However, the gray wire is now showing 5V. The yellow remains dead at 0V.

Can you pls. advise which circuit board is suppose to supply the power to the yellow wire. I understood that the yellow wire came from the reader controller, but understand it may come from the DADF DC Controller PCB?

Thanks.

Reader & DADF / are Two Different items

Thanks for illustrations. The DADF has a circuit board that J1 & J2 connectors plugs into. I understood this as the DC Controller PCB. The J1 & J2 plugs come from another PCB, which I understood was the reader controller PCB.

Bottom line is that the yellow wire on the 7 pin connector is not receiving the 5V DC that should be there. Am trying to ascertain if the power to that wire is being deprived by hardware issue or software.

Am not sure why when the DADF was observed this morning it was detecting a paper in the unit vs. no detection before. However, when restarted the printer, it is no longer showing any life, but the gray wire on the 7 pin J2 connector is at 5V now.

Am still leaning towards removing & replacing the circuit board that the yellow wire comes from & welcome any suggestions on service mode adjustments.

The two pin connector & seven pin connector on end of CN1 interface CABLE
it interfaces between DADF CONTROLLER & Reader Controller . There are wires behind J4100 that lead to Reader Pcb.

DC Voltage is supplied from Printer to Reader to DADF
