IPF6300s multi-sensor troubleshooting

[ATB]

Hi and first of all let me thank you for all the knowledge I was able to acquire here!

That said... I'm trying to revive a 2nd hand canon IPF 6300s which apparently has problems with its multi-sensor.

If I try to load paper (manual A4) the sheet gets loaded but no lights from the multisensor (error 200C: Roll paper leading edge detection error).

If I try to recalibrate it, I get a 2F32 (faulty multi-sensor); I tried to replace (with new ones) the multi-sensor and its cable with no effect: still no red (or blue) light from the multisensor at printer power-up or while loading paper (cover open with sensor closed so I could look; and yes, in a very dark environment to prevent external light from messing up with the sensor).

Premise: the printer probably had faulty heads as I remember last time paper was loaded I heard a "bump" (like the soundy flash of a photo boot when you take a photo for your ID) and saw an instantly bright light.

Can you please help in trying to troubleshoot where the problem is and fix it?

Thanks a lot!
Alex

Re: IPF6300s multi-sensor troubleshooting

My knowledge is based on the iPF-785, but some it may be applicable:

On the 785 it is necessary to do the gap adjustment and optical axis adjustment. Did you do these adjustments?

Usually if you have a multisensor issue, when you do the gap adjustment it immediately goes into a 03130031-260E error. You can do an Optical Sensor Output, but the manual does not get very specific about the meaning of the output values. So I started logging the values into a spreadsheet to identify which values are indicators to watch. Output 2, items 11 & 13 seem to indicate a bad sensor ... I'll attach the document, just keep in mind that the data is collected on the iPF-785 =^..^=

Re: IPF6300s multi-sensor troubleshooting

Thank you very much for your answer and sorry for coming back to you so late.

I tried the gap adjustment as suggested in other posts but after starting it stops with a multi-sensor error and still no lights. As the light don't blink at power up I think the problem lies elsewhere: how can the calibration can be done with no lights coming out from the sensor?

Did you look at the optical sensor output? =^..^=

Re: IPF6300s multi-sensor troubleshooting

Hi BlackCat and thanks for your answer.

Can you be more specific? I searched for "optical sensor" but couldn't find any mention of it in the troubleshooting guide or the parts list, only purge sensor, PE sensor, variopus cover sensors, multisensor, cassette sensor, roll sensor, paper sensor, spure cam, ecc.

Thanks!

Re: IPF6300s multi-sensor troubleshooting

Sorry, I don't have the iPF6300 manual to browse through, but every other manual I have shows OPT SENS OUTPUT in Service Mode > FUNCTION > OPT SENS OUTPUT > YES. I would be very surprised if it was different on the iPF6300. Did you look at the document that I attached? =^..^=

Re: IPF6300s multi-sensor troubleshooting

That's me being sorry, didn't associate the two things. Here's the list:

OUTPUT 1 546090004 3???
OUTPUT 2 563093004 4???
OUTPUT 3 672090003 3???
OUTPUT 4 785090020 9???
OUTPUT 5 701089211 9???

Thx!

Re: IPF6300s multi-sensor troubleshooting

There are six outputs including output0.

From what I see #17 GAP 2 outside light output is not within desired limits. I'd replace the multisensor and multisensor reference, then do the gap adjustment and optical axis adjustment. =^..^=

Re: IPF6300s multi-sensor troubleshooting

Thx.

I have other multi-sensors to replace with and check what the error codes will be but what about the fact that any of them is emitting light (even after replaceing the cable)?

So should I replace the sensor, run the gap adjustment and post again the sensor outputs?

Yes.

Re: IPF6300s multi-sensor troubleshooting

I'll do that at once. Running the gap adjustment before remove this sensor and will do the same afte replacing it.

If there's a faster way to collect the outputs (L printer tool, web interface or other) please let me know,

I'll be right back with the outcome shortly. Thx again!

Yes.

Re: IPF6300s multi-sensor troubleshooting

after gap adjust (carraige moves towards whit plate) and I receive a "Multi-sensor error. Turn off printer, wait a while, then turn it on again."; before replacing sensor: no difference with previous outcome (forgot to mention output 0 642090003 3???).

after replacing the multi-sensor with the old-one (the one previously installed should be the new one I bought): I receive the same error (MS error, restatrt) as soon as I start the adjustment (before the carriage moves).

Output readings:

0 642090003 3???
1 546090004 3???
2 563093004 4???
3 672090003 3???
4 785090020 9???
5 701089211 9???

I still have another multi-sensor to test if it can be useful.

Re: IPF6300s multi-sensor troubleshooting

You have no ideas about the provenance of these parts? =^..^=

Re: IPF6300s multi-sensor troubleshooting

I bought cable+multi-sensor online from iteminc.com . The cable came in i a plastic bag with canon label, PN etc.
the muti-sensor was in a small generic paper box.

SL#	ItemCode	Item Description	Ordered	Shipped	Price	Amount
1	QK1-2758-000	Canon IPF6300 Cable, Multi Sensor	1	1	$12.00	$12.00
2	qm3-0365-000	Canon IPF5100 Multi Sensor Unit	1	1	$53.00	$53.00

But the fact that previous sensor blew up in a flash and any is emitting any lights makes me fear the problem is elsewhere...

You have no ideas about the provenance of these parts? =^..^=

Re: IPF6300s multi-sensor troubleshooting

There certainly are other components involved. The multisensor connects via a ribbon cable to the carriage PWB. Then there's the trailing cable connecting to the controller PWB, and the controller itself. And the power supply.

You have as decision to make. How much money are you going to put into this machine? Where to stop?


From what you've described, you'll need another new multisensor and whatever additional parts that you'd like to try next. =^..^=
