Canon iR5070 E025-001

[jsw2k]

I've replaced the toner motor M9. M10 checks with the diagnostic. Can't find a fuse on the DCon as noted on an other thread (regarding an iR5065).

I've searched the machine for a blown fuse but only found 2 or 3 fuses (and a breaker), which all checked OK on a meter.

I can actually get the machine to come to ready and even make a few copies, if I leave the toner access door open at initialization.

Anyone have a suggestion?

Thanks!

inspect the wiring harness for M9 /
remove tie wraps to inspect for frayed wire or a short


FU15/ it's about checking for the resistance/
right below connector J103 on the DC Controller
not all fuses look alike-------------------------------

reported on Canon Grid search / by John_W
techs in the field report >that they find pieces of the toner bottle nozzle in the sub hopper. also check for check sub hopper for debris or binding. customers need to be told to be more careful installing or removing a toner bottle.
M9 overheats/shorts out internally) then blows pico fuse FU15
it's a PICO fuse/// Voltage: 125 Volts
Current: 2 Amps---------------see example picture--Part # VD7-0622-001


not all fuses look like fuses

I going to have to ask... Do you got the right toner cartridge in that hopper. GPR24

I know it might a silly response but I have seen this happen plenty times. Customer tend to put the wrong toner cartridge, especially if there are other machines on site, like a 7105 GPR19. These cartridges all look the same to end users. They don't know about the gaps on the cartridges.

Re: Canon iR5070 E025-001

Thanks for the responses!

I have a photo of the DCon and yup...lots of those fuses. The text is so small, it's hard to see. In this caes, those fuses are a yellow-browish color. I'll go back an check FU15.

I didn't check the hopper for broken toner bottle bits but, since there are over a million pages on the printer, there certainly could be. As to the toner issue, they only have one copier on-site and get their toner from us, so I don;'t think that's an issue, but I'm-a certainly gonna check!

Thanks again. I'l button it up if this is the answer; I'm expecting that fuse to be bad.

Re: Canon iR5070 E025-001

Double check if you plugged the motor into the connector. I have seen that happen a few times
IF it works with the toner door open the fuse on your DC controller is fine

Re: Canon iR5070 E025-001

I can't say it works with the door open; I'm able to make a couple of copies before it goes in to the E25 code. I can't get the motor to run in service mode. So isn't it possible that fuse is still blown?

not blown but it could have a resistance issue/ (high)


just like those pico fuses on the 3200/3220 fuse pcb > a continuity test means nothing on them (never use that test on them> these fuses must be checked with power on )it's all about the correct voltage flow (example; if voltage reading should be 3v and it reads 1.5 u have an issue as in Jams & Errors >like in the Duplex operation >a know fuse issue on that series

Re: Canon iR5070 E025-001

Do you recall what that voltage should be?

may be on fuse/ or stamped on board below it

Re: Canon iR5070 E025-001

Just to make sure. I hope you changed the right motor
M9 is not the white boxy motor easily removed, without taking the hopper out.
It is the bulb like motor covered in transparent plastic. difficult and messy to get to. FK2-0813

this is your quote.....

Re: Canon iR5070 E025-001

That connector needs to be fully seated. I followed another tech once only to finish the last mm of the connection. I have had motor and dc go at same time.

Double check if you plugged the motor into the connector. I have seen that happen a few times

Re: Canon iR5070 E025-001

usually if a short to a motor is involved > it always reverts back to the fuse location in bus line> be it on a Fuse pcb or DC pcb > either completely blown or damage resistance> the high resistance reading could affect the correct current flow

Transient surge or pulse currents are used to describe wave shapes that result from any startup, inrush,
surge, or transient currents in a circuit.

Pulse currents can produce thermal energy that may not be large enough to open the fuse but could
possibly cause element fatigue and decrease the life of the fuse.

A series of pulse currents will eventually create enough heat to shift resistance or even permanently
open the fuse.

Pico fuses are color-coded for amperage rating and only produced in solid colors.

PICO Testing
Locate the negative input to the circuit board. It will be indicated by a dash sign and the positive input will be indicated by a plus sign. Turn the power supply on and touch the negative probe to the negative input. Probe each side of the suspected Pico fuse. If it is blown, there will be power on only one side.

Re: Canon iR5070 E025-001

Excellent! Yes, it was M9 that I replaced; had to remove the whole assembly to get it out. Double checked that connection.

I'm back there on Monday. I'm gonna be looking at that fuse.

If we rely on the documentation, E025-0001 is caused by an over-current detection in the toner feed motor circuit. Then, the protecting Dc controller fuse is OK (otherwise it is an open circuit and the error code would be E025-003). The Dc controller is detecting a heavy load in the toner bottle driving system. As stated by Teckat : "techs in the field report >that they find pieces of the toner bottle nozzle in the sub hopper". Have a look on it.
