I think I have done about all I can do - im failing on this one



Company bought machine ( as new ) on Colour = 300 & K = 200 - was told toner hopper was faulty which it was

what had been done

New K toner hopper & toner motor
all firmware updated
Manual Pro Con

Vsg reg front center rear = 4.93
TD sen Ini set result - 1111
TD sensor clean
changed TD sensor

all parts listed below moved to another working machine and all was good, no visible issues on test sheet =

PCU's
ITB
Fusing Unit
Registration Roller
Laser Unit



Am I missing something?

Thanks in advance

Re: MPC 307 faulty test sheet

I would say make sure the LD shields and ID sensors are clean first. Perform a forced toner supply on all colors. Run ACC. You also may have to reinitialize K developer after you achieve a good K solid from the forced toner supply.

Perform SP2-111, Forced Line Position Adj., All steps.

If client doesn't complain, let it be

Its going into a Nursery where they print photos off for the perants.
you can bet your bottom dollar - they will notice.

It shows up at the top of the page if text is presant, and the client is in London which is miles away from where we are on the coast.
Dont fancy a revist

Hi dave one of the problems you have when you use pcdu's from another machine they don't set up unless you run manually also toner hopper problems always give you faulty add toner sign I would check the pm life's. Do forced line adjustment in correct order. Also if you require I could always have a look for you i'am based in London. Also if you did do toner hopper you would of removed laser ribbon cables hopefully they not damaged

changed all that stuff, and don't go?
try while printing to keep the door closed with one hand, pushing hard ... and see what happens, maybe it doesn't close well (?)

Good call - BUT still the same.

Thanks anyway

Re: MPC 307 faulty test sheet

Thanks to all

Went through everything you guys advised - the Test chart is better and doent show any symptoms when printing text.

Thanks again

Hello!

This post might be too little too late and if so I'm sorry...I don't get a chance to hop on here very often.

Question...the page you posted, was it printed short edge feed or long edge feed? If long edge feed, then your K PCDU is the problem. Developer could be clumping up and clogging up the brush. Fix action is to take a piece of plastic (about the thickness of an ID badge or credit card) and stick it in the gap between the drum and dev unit and swipe it back and forth to break up the developer.

I had this same issue with an IM C3500 on the K PCDU. I printed a checker pattern test page for all 4 PCDUs and it was only the black that had voids and faded prints. (much like the bottom corner you circled)

I did what I recommended above and it prints like brand new again.

Credit goes to a guy on youtube that I stumbled across researching the problem.....I forget his name though.

Cheers!

The C307 is ONLY capable of printing SEF.
He clearly stated that basically ALL parts work perfectly in another machine.
The solution you provided sometimes helps if there is a distinct blank line on the image due to 'toner rocks', but that's not the case here at all (he circled BOTH corners)

Re: MPC 307 faulty test sheet

Thanks Vegas Biker

Yes the card slide trick, was shown that some years ago and works well when you can see a line on the mag roller.
