[CQ] Dark magenta line exactly same on 2 SPC440 and 1 SPC430 printers

[mlandry71]

This is too much of a coincidence. I have to see if someone here has the same issue...

Client has Ricoh SPC440 with under 50k pages, purchased new last year.

Client printing sunset images on cardstock for thank you cards has dark line down left side of page only in printed areas (oranges and dark yellows show it well). Called for service.

During initial diagnose, set Engine SP2109-3 to 11 (1-dot independent) and printed the internal Service SP1103-2 once for each chosen color in SP2109-5 (all, c, m, and y)
Dark line shows only on magenta filled print about 1/2 inch from the left edge (feed direction is up).

(See attached image)

Ok. Must be the drum. Ordered new SET (can't get just one, dammit!) Installed new drum unit (which is complete pcu with developer filled and all) - no change!
Maybe transfer belt. I have an SPC430 here in my office. I'll try that belt. - No change.

Put that belt back in my machine and thought to try a test print. Same line in magenta only, in the same exact position.
Did it spread?

Went to another client with same model SPC440 and printed the same tests above and got THE SAME RESULT. Never even opened the covers. ..and they weren't even complaining about it...yet. Hmph.

If someone has access to one of these series printers, could you please try to see if this is a common issue or not by printing a 1-dot from each color? (If you don't know how to get into service, I won't help. It's for your own protection.)

Looks like the result of a dirty charge roller.

OK let's think about this:
Laser forms latent image on drum...
(process step missing)
drum turns puts image on page...
What puts toner on the drum?
**Hint developer unit**
OEM Toner?
Are the paper WEIGHT settings proper? *Heavy/Thick 2 or 3**

Re: Dark magenta line exactly same on 2 SPC440 and 1 SPC430 printers

While I have no Advice for you.
SP C430 here. Same thing. Strange
OEM toner. only 7K on the meter

One piece of advice I can offer as far as drums go, is that the drum portion of the PCDU can be used for any colour. Just remove it from the dev unit and set the dial on the back to the proper colour.
I also mod the dev portions by grinding the corner off of the connector and swapping TD sensors and a couple of wires and they can be used in the MP C300/400 & 401's.
Why you ask? Because I can buy SP C430/431's with very low meters for next to nothing

did you pull all drums and wipe the slit glass..shoot some air
I had one that was a mess and had no wand so i just wiped it without drums and ITB unit..

Dirty laser should cause white line, try swapping M drum unit.

Re: Dark magenta line exactly same on 2 SPC440 and 1 SPC430 printers

Well, thank you all for the suggestions.

While it does look like a dirty charge roll, this happens even on brand new, oem, just-out-of-the-box pcu's (they are combo drum/dev units that are cru's), and still only in magenta.

As far as swapping drums within the units, I have done that too, with no success. I assume I need to focus elsewhere.

You can order individual color PCDU as service parts out of the parts manual. However unless you only need one it is a better investment to buy the three pack as supply item.

Thanks! How did I miss that one?

For reference (from spc440 parts man):
M0662015 PCU:C:SUPPLY:ASS'Y
M0662016 PCU:M:SUPPLY:ASS'Y
M0662017 PCU:Y:SUPPLY:ASS'Y

Doesn't look like many of the usual vendors carry them - at least in the US.

you can pull these apart and rebuild or at least clean the charge roller..
the fabric roller is very soft and you need to not touch it with force..
The mpc400/401 are the same unit,just swap out td sensor

Re: Dark magenta line exactly same on 2 SPC440 and 1 SPC430 printers

Just some additional research findings...

I think I've found a factory defect because i just got a machine in from wholesale with only 17k total and 9.5k of that is color with the dark line in the exact same place. What to do... hmm.
...I guess I'll post a fix if I find it.

I guess you just disregarded my post with samples showing you that my 7K printer does the exact same thing?
Fair enough....

Sorry to sound dismissive. I do thank you very much for providing evidence of this defect.
I'm just trying to build as big of a case as possible so someone at Ricoh might take notice.

In fact, when I do bring this issue up, I always mention that you also found the same thing a thousand miles from here.

I tried calling some vendors with Ricoh factory connections, but their support is either on vacation or just doesn't know anything.

If you are with an authorized Ricoh dealer and you were really interested in building a case, the first person you should have contacted would have been your regional service support rep. In fact if you have been with Ricoh for any length of time, you or your boss should be on a first name with him/her. There is a procedure that you have to follow and CTN is not a part of that procedure. They will want detailed information on what problem(s) each machine has had and exactly what you have have done and the results.

Re: Dark magenta line exactly same on 2 SPC440 and 1 SPC430 printers

Just out of curiosity:

Does this defect appear on all paper sizes, all media types, all trays?
Does the defect reduce/enlarge when the electronic image is manipulated?
Can the defect be seen in the latent image on the magenta drum, when emergency stopped?
Can the defect be seen in the latent image on the intermediate transfer belt, when emergency stopped?
Is there an identifiable interval that might clue you in as to the source of the defect?
And it always appears in magenta only?
According the brochure it appears that 8.5" is the maximum width, true?
