Ricoh C2050 light color lines(with attachment)

[Nortenio]

Quick final update for everyone, I guess we took the thing apart and cleaned the transfer unit and that did the job.
Beats me why it wouldn't be scanner/ optics; we didn't order an sbu.

Thanks for your troubles tho!

It IS a scanner / optics problem!!

tut tut tut.

Meaning??

If the lines rotate in "Auto reduce / enlarge" How could it be the transfer?? Therefore the description was wrong!

i hav'nt realy processed all that sub scan blah blah . But i have hade very simular problems and the problem has been solved by dev changes. use single colour mode and do a sky shot in each colour and see if you are getting faint lines on any of your sky shots. Hope this helps.

Agreed, both the description and diagnosis were wrong. Very common in this game.

Diagnosis was "right" (Pointing towards the correct area) for the description given.....

The "sub scan blah blah" is how the machine works!!

It's a common problem that terms like "Portrait" and "Landscape" are used to describe copy quality probems... Now, THAT'S "Blah Blah"!!

Those terms have no meaning when used on a digital device as the image can be manipulated electronically. If the person at the machine understands (As we all should) the concept of Sub Scan and Main Scan, the tech on the phone or the internet can be told what is ACTUALLY happening!

In this case, it was indicated to me (us) that the problem ROTATED from A3 to A4 LEF in Auto reduce enlarge, which WOULD indicate a scan problem. If you can tell me how transfer can cause the problem to rotate I'd be very interested! It now seems the lines did not rotate. By the way, your idea of sky shots wouldn't prove anything as you would still be using the scanner and throwing dev at the machine is a bit of a "Shotgun" approach. Test patterns would help to eliminate the scanner.

i have had the problem with faint lines on these models and tried to clean the doctor blade with a bit of card and moved the position of these faint lines by doing so, then i changed the dev and problem solved. i understand the relevance of changing the direction use reduce/enlarge but i dont believe the scanner is the problem.

We now know it wasn't the scanner, as the fault is apparently gone, but the point I'm trying to make is that without the person (Who may not be a tech) describing the fault correctly, it's not always possible to diagnose the problem, especially when they say one thing and mean another. (As in this case where the lines apparently turned from the paper feed "sub scan" direction to across the paper feed "Main scan" direction) I have had this problem a lot with my colleagues. but now have them a) understanding the process, which incidently reduces the tech calls considerably and b) Explaining the problem to me in the correct, basic, terms which allows me to (usually) give assistance, or pass the problem to Ricoh tech without them getting confused.

I suggest reading the Ricoh Core Technology Manuals (which are freely available) from time to time, to refresh knowledge as the majority of problems can be fixed by asking the question "How does the process work"

thanks for that but i think i'll be o.k i'm fixing these things for 20 years.

Wasn't aimed at you.

But that's how I felt as well (23 years) nuff said, thread closed as far as I'm concerned.

I am still yet to determine where you got the idea the image was rotated. Was it in the post with the whatchyamacallit? If so, not very conclusive.

I know this thread has been resolved, but thought I had to get my two pennies worth in here. My initial observation tells me that there is a lack of toner in these areas caused by crap in the dev unit. The colour of the faded lines seems to change, depending on the colour of the area being printed. I find this a lot on the mpc 28/3300. And if these machines are anything like the affore mentioned, that's where I'd look first. If twenty years has taught me anything in this game it's keep it simple. A lot of folks look at the worst case scenario first. It's also handy bearing a machines quirks in mind when looking at a problem....... Ok I'm done now lol

"Instead of an A3 I put 2 sheets of 8.5x11 on the glass side by side. Now, instead of the lines going in the paper feed direction they go the other direction;"

Seems about as clear as you could ask ...."instead of the lines going in the paper feed direction they go the other direction"... Just about precisely answered the question I asked.....At some point you have to take their word for it! anyway, the Crystal Ball is in for a service, so there wasn't much more I could do!

Yes, unfortunately our devices don't come with a 'psychic option'. We must rely on 2nd and 3rd hand information sometimes, like the game "telephone". By the time it gets to us the stated problem bears no relationship to the actual problem.
