RICOH IS-330DC: Vertical Stripes on every Scan

[NewOrder]

Hello,

I recently noticed that my scanner "produces" vertical stripes which are especially visible in darker areas of the picture (see attachment!)

Any Idea how to correct this?

I would first clean all of the optics.

hmmm, nothing to clean but the flatbed-glass-surface...I also tried several positions within the flatbed...same result...

are you sure the poor quality is from the scanner and not from your output device?

Also you sound like an end user. There are mirrors inside the device that should be occasionally cleaned by a certified service professional.

There are two possibilities. It's either a software problem or a hardware problem. If it's software you should be able to resolve it. If its hardware a technician should be able to solve it.

If it's software it could either be the Ricoh twain driver or the scan router software. you can bypass the driver and scanrouter (i think) by using photoshop to interface with the scanner directly. See this website for details.

I'm assuming that bypasses the Rioch driver but i don't really know.

If it's hardware there could be any number of causes. As eric1968 said the place to start is cleaning the optics. It may be a bad xenon (SP?) lamp. It could be a dirty white plate. It could be a faulty logic board or a bad connector between boards. But again the hardware side should be looked at by a technician.

Hi Five,

I AM an "End-User", but with technical interest and/or abilities. Tell me how to clean that device and I'll do! ;-) I can't afford engineers to do the work, so I'm asking you (all). Furthermore the RICOH-Hotline in GER wouldn't cooperate if you're not a technician / sales-partner.

I don't understand why - if there's dirt etc. on mirrors and/or lenses - the WHOLE scan looks that way (colors, brightness...). In my opinion regular stripes mean, something's moving inside, e. g. the sledge stops (memory is full), drives back and scans again, something's rotating etc.

Sorry for my naivety, but I want to keep my things work properly.

PS: What do you mean with "output-device"? Printer? Monitor?

uh, my last answer was the reply to your first posting...Translation costs time...now reading your second reply...the answer comes within hours!

If you do a scan with the cover up and nothing on the glass you'll see an element move across underneath the glass. (i think its UV light so take all the proper precautions, not that I know what those precautions are haha) That is an assembly that includes a few mirrors and a lamp. These are what most people refer to when they say "optics".

A technician will power down and unplug the machine, take off the three screws above and to the left of the large glass, and remove the large glass, the small slit glass to the left, and manually pull the scanning element from its home position along the rails out to the right. A tech will then use a microfiber cloth (Ricoh recommends using a lens cleaning blower brush only) to clean all the mirrors and the lamp. They will also clean the "white plate" that's on the underside of the assembly that holds down the slit glass as well as the slit glass itself (rubbing/isopropyl alcohol should be fine for the slit glass). Do not clean any lenses inside the machine.

The primary danger when working on this machine is cutting yourself on the metal inside the scanner (the edges are very sharp), the risk of fire, as well as the danger from the energized rails when the machine isn't unplugged (20,000 V i think?). And of course there's the risk of damaging the machine.

The above is the first step a tech will take for image problems related to the scanner.

I just thought of a another potential cause for this problem, it could be a scratched slit glass . A tech can hold the slit glass up to the light to check for wear. Here's where you can find a replacement part that may fit that machine AC01-3004 Exposure Glass - Pronto.com I'm not affiliated with pronto.com so of course, buyer beware. Ac01-3004 is the Ricoh part number.

and by output device I meant whatever printed your original.

still testing...

...still testing/reading Service-Manuals/enjoying the good weather...

Happy Easter! Need more time to test...thanks for all answers, especially Mambo Nr. Five! ;-)

Try using Scanprobe I don't think it uses the twain driver. It should be able to tell if its a software problem or not

Hi Five :-) , Hi Knightfall,

thank you! Sorry for my late answer...tried to fix too many issues on that device in the same time (see http://www.copytechnet.com/forums/ri...er-sc4001.html)

The Picture I posted was scanned with PhotoShop, "IS330DC Network Twain Driver" and it doesn't offer other choices.

I think it's a hardware-problem - although other pictures with much dark parts are scanned perfectly (mostly after the scanner is turned on for a longer time). The Device-Counter in Service-Mode tells only "46 hours lamp on" although the IS330 scanned approx. 220.000 Pages (ADF) and 900 pages (Bookmode), so I can't imagine, the XENON-Lamp is worn out.

ScanProbe doesn't find the Scanner via network, only some parts of the proggie worked...so I took the device to my local RICOH-Dealer...not only for fixing that stripe-problem (see my other post). At the end of the week I'll be wiser...
