Sorry i didn't reply yesterday. Had a day off replaceing door- an drawerfronts on my Ikeakitchen

hope it was a sucess and they haven't fallen off or anything

ok, I asked for obvious reasons, the 2020 has an AVP of 5000 but based on your answer I guess you don't cllect the counters regularly.

I guess we go back to highvoltage assembly FM2-4018-080

questions regarding the actual machines status:

is the machine plugged directly into a wall socket or is it plugged into a floorbox/extension lead?

has the machine been moved recently?

Not yet But one didn't get delivered, and one i ordered the wrong size
Oh, and i have some screws left over. but that seems normal with Ikeastuff...

Only on visits, maintenance and repairs that is... So i would have to look back every call. Sales hav'em in a list, but i'm not getting it from them...

the loose toner on the ITB still puzzles me, can it be a consequence of a failing HV PCB ?

Yes and No....

I'm looking at these cyan PG5's and I see pitch lines. Typically these machines tend to show the lines more as the drums wear...

I have had a nice few issues with these machines, but never go through drumsthat quick.

I would venture to try an HVT at this point to see what it does, but it literally could be just crappy drums. I've seen sets of these things DOA two and three times in a row. Not sure what the hell is happening with these drums - I think they had a bad run in manufacturing.

haha yea, do it yourself stuff usually adds extra stuff to make you doubt yourself with the 'mmm...I'm sure I don't need these but....'

yea, a failing HVT would mean that the charge on the drum surface isn't being applied correclty, this would explain the high attrition rate of the drums (damage through voltage applied) and could result in the toner both not sticking to the surface of the drum correclty and thus 'spilling'.

always worth asking, diffrent people have diffrent methods

Ok, had a nice talk with canon Support today. HV PCB + Cyan drum could be an optionto solve the problem for now...
But they could not give any guarantee if it would be the end of the trouble, seen the history of the machine. They advice to swap it for a 50xx

So that's what i put on the desk at the customer AND our Servicedesk, so either way i'm covered Either it's swapped for a 5030 or alike, or I replace HV PCB and drum, and if the problem comes back and I say "Told you so..."

If it doesn't come back, I've done a sucessfull repair

Re: Canon IR Adv C2020 - only 1st print ok, next prints have blue streaks / is darker

haha yea, when you start getting to this point canon tend to start going with the lines of it may or may not work. when your at that point then they are starting to run out of ideas themselves.

well yes, a 50 series is certainly a viable alternative, just got to hope you don't have a spat of E75 errors, make sure if they do go that route that the ITB has had all the mods fitted before it goes on site or is new enough to have had them at factory.

good luck

Ok, so i need to get a SM of the 5030 somewhere then

Been back onsite this morning, trying to get some of the nasty Cyan streaks out, so they can at least do some printing. The streaks are real bad on "normal" prints too now

So i need some temp. workarounds.... Cleaned the whole machine, in-and-out but laser and drum looked quite normal. the sec. transferroller was verry blue-ish though. I cleaned it, did some 10 yellow PG5 at dens 255 and the prints where at least readable.

2 hours later the customer called; the streaks are back.

Well, the office doesn't really want to spend any money anymore on this machine. I have a used Cyan drum left over from another repair this afternoon (67% but 1 white stripe) and i think i'll just try it


Btw. the afternoon-customer has 2 2020's on that site. The other was FUBAR according to one of the staff.
What do you guys think of this :

Error E0000074-ffff (ITB Rotation error, no kidding )

I've had a number of parts for these machines show up at the office broken. Presumably an issue with Purolator as they just toss everything around even if fragile is written on it.

Anyway, I had a brand new one of these rip one time just as I turned the machine back on - discovered it was due to a transfer roller being out of place and it forced the edge of the belt up high enough to catch on something. We opened up the box for a few other new ones and they had the same problem. Called Canon about it and they told us there were a few reports of the same issue, so must've been a manufacturing issue at the time....lately no issues though.

Re: Canon IR Adv C2020 - only 1st print ok, next prints have blue streaks / is darker

ok...so we are now onto a 5030i correct?

Cyan streaks, so you've checked the drum and the ITB were both ok, and also the laser...what about the cleaning blade?

it actually sounds like the developer for the Cyan tbh, I've had those go without real reason before.

Re: Canon IR Adv C2020 - only 1st print ok, next prints have blue streaks / is darker

Yeah, it'll probably be swapped for a 5030, but in the meantime tey asked me to make the printer at least usable w/o using parts.

Sure, and i can tell you the winning numbers for the lotery next week too...

lol.

ah right so the cyan streaks are in the 20.

erm...tell them to only print black and white that will solve their problem

Re: Canon IR Adv C2020 - only 1st print ok, next prints have blue streaks / is darker

Ok, got back there this morning.... Cleaned the whole thing with the tonervac, ITB cleaning, sec.transferrol cleaning, Grad.adjust run some test and after app 30 print i was back to square 1.
Tried the old fuser, but a 3 hour drive vertical and overnight in the van was to much. it totally jammed...
got it out, tonervac'ed my pants And vac'ed the 2020 again.
Told the office i needed a drum or another copier

Well i did get permission to replace the Cyan drum one more time... So i did the whole tonervac-thing + cleaning again, replaced the drum, did a grad.adjust and the printouts looked pertty decent, apart from the old problem, the colordiff between page 1 and 2 etc...

So on top we had a leaking toner...



Oh, the replacement will be a 52xxi with postscript and such... (imagePASS-B2-controller ?)
It'll come in next week, I will then have to build it up before it's delivered...

Come to think of it, maybe it better to (partialy) build-up at the customers site.... Their on the first floor and there's no lift
OTOH, i want to do a DOA test before...
