Docucolor 240 not imaging magenta

Re: dc252 line

Great tip. I'll keep it in mind. An ounce of prevention... yada-yada-yada...
Indeed, a pickable brain. You are my new best friend... (Stalking laws may vary from state to state [/disclaimer].)

But to careen recklessly back on-topic, if Magenta (the hot pink one) was imaging prior to tech-monkey intervention, and is not imaging now, Troubleshooting Law dictates the problem likely exists in the area of tech monkeyage.

Haha.

I agree on the missing magenta. I would say that it is either the flat cables or not getting the mirrors or lenses back in quite right. They just really shouldn't ever be removed from the ROS housing. Since not having the flat cables plugged or seated just right should generate an error code (not that I know form personal experience or anything!) I assume it is the mirrors and lenses. They may all be back in, and may be in the right location, but the angles or something might be off.

It's a bear getting to them, but I would recommend the OP swap the YM ROS with a known good one, if he has one he can swap with. That would answer the question pretty easily.

The problem as I saw it was that as the developer assembly aged, it would create too much dust. This dust would get up onto the felt pad which rubs against the charge roller. After it builds up enough, it would actually "scour" the charge roller, creating streaked prints. No recovery once this has happened. (Side note, the 700 and 550/560 drums are identical to the 250/7665 drums except the felt pad that rubs against the charge roller is itself now a felt ROLLER. No more scouring.)

I've seen these charge rollers sold on internet (China). Do you have any experience with that? I've got offer to buy 40pcs, but it's to much and I'm not sure would it work.

Aftermarket BCR....

I've had poor results with aftermarket BCRs.

Re: Docucolor 240 not imaging magenta

I've also had poor results with generic charge rollers. Generic ANYthing. I've tried several different manufacturers, and they are all bad. Like so much of the generic stuff (especially toner) they just throw something together as quick as they can, call it a product, with no regard for how good it actually is.

The best (and by "best" I really mean "most pathetic") part is, when you mention that you've had trouble with their part, they insist they've had no complaints from anyone else and blame you.

I caught one in an outright lie actually, since both I and a someone else I know were both testing the same charge rollers and belt cleaner blades. Dealing with the SAME guy. Said his products were perfectly received, no problems, no complaints but I knew less than a week prior the other guy had also complained.

It's really lame.

Re: Docucolor 240 not imaging magenta

I'm trying to stay vaguely on-topic here, and I think it's pertinent since we're still talking xerographics...

Couple schools of thought on aftermarket parts:
They Suck
They RAWK

I probably fall somewhere in between.

The They Suck camp really just wants a quality product. The They Rawk side are generally either bean counters & owners, or service managers (bean counters in training)... did I just say that out loud?... Well, it's nothing I wouldn't say to a service managers face, and they know it's true. At least, they're the first to laud the benefits.

At the end of the day, anything that saves the outfit significant dollars is an ultimate win... But where to draw the line... Absolute efficiency isn't always the answer and we, as field grunts, have to accept some compromise thrust upon us. And face it, the numbers watchers tend to be the bosses. What is needed here is Relative Efficiency (and plenty of Excederin).

So how to make the best of imperfect solutions? It's a madening excercise.

Idealy, I'd like to pick and choose my aftermarkets (and good leadership will listen to reasoned aguement). In the realm of hardware, I've found some rollers, for instance -- particularly fuser roller -- with a better yield than OE. In the area of consumables, it gets sketchy.

Toner/drum/developer issue generally show up late in the game, once they have become thoroughly assimilated into the xerographic collective and have a chance to work their diabolical magic... Buahahahaaaaa! Problems begin as niggling concerns, annoying callbacks, and finally, squinty-eyed suspicion.

Track, track, track! Document everything and build a solid and reasonable case for pulling the item. With samples of detroyed components, if you please. (Remember, these aftermarket vendor reps come out to wine & dine the Head Honchos, spring for golf games and drop complementary Mont Blancs in linen pockets... And most importantly, flip spreadsheets with eye-popping bottom lines.) Some fieldies don't consider this their responsibility, to convince leadership... Well, they don't really want to be in the business, do they? That's okay. It leaves little other option than to shut up and do as you're told... Just the fax, ma'am.

That said, that sticky, waxy Xerox toner has got to be particularly difficult to replicate... and anything aftermarket associated with the 260/7675-style prima dona drums can be nothing short of bad juju.

Not to mention the trickle developer system (which I'm not 100% sure these DC/WC lines use)... Now one has to reverse engineer, essentially, a dual-component toner... With Xerox? Good luck. I'd love to see it done.

Bright side, anything short of a completely successful attempt should be an immediate and catastropic Fail.

Re: Docucolor 240 not imaging magenta

I'm just an individual user supporting my own machines, so I focus, narrow but very deeply, on the ones I have. Not part of a service company or anything. But as far at the generic supplies specifically for the DC250, etc series, I haven't found anything yet that would be even remotely acceptable, regardless of how much cheaper it is. (Fuser rollers being the possible exception.)

This is what I've tried (specifically for the DC250) and my opinion of the results. (I won't get into whose products I tried or anything like that except by private message. This just isn't the thread for that.)

TONER - Complete failure. 0% usability.
(I've heard that there are some people selling toner from the very same manufacturer that Xerox uses. It is more expensive than I pay for the real stuff, though, so I've never tried.)

BELT CLEANER BLADE - Meager results. 25% usability.
(Doesn't last nearly as long as an OEM blade, and while you can clean an OEM blade and it will be good again for quite a long time, the generic blade couldn't be cleaned and reused. Just as bad after cleaning.)

PCR (color drum) - Mixed results. PCR's from one vendor worked pretty well, but PCR's from another vendor were complete failures from print #1.
(The tricky part is that the PCR's in question from both vendors looked, and were packaged, _I_DEN_TIC_ALLY_. Which makes me worry, like they're from the same source and that source has really bad quality control...)

FUSER HEAT ROLLER - Still testing two different manufacturer's products of these for a buddy, so far so good but too early to report.

Wouldn't have guessed it.

Look forward to FHR results. Ours are adaquate-to-superior so far.

Re: Docucolor 240 not imaging magenta

OK guys, thanks for your inputs..
I always use OEM toners and spare parts, that's what I've have learned long ago.
Just needed opinion about these rollers. Thought it could work. Thanks again for sharing your experience.
printprocc sorry for using your thread to ask my question.

Cheers

[Ianizer]

How'd it go, Printprocc?

Re: Docucolor 240 not imaging magenta

Hey thanks for asking. Quite well actually. I finally got tired of trying to fix them one at a time and did my slight mirror adjustments rather on the fly with the covers off. Run a sheet, make an adjustment. and so on. After an hour I got it right and all is good. Terrible mistake to make but I do learn from experiance and that won't happn again.

Thanks for all the input and help. We got er done.
