Dwin Trans 3 Shadowing at Edge

3 yr old projector with shadowing at edges angulated on left edge and bottom.  I thought this was related to a mirror tunnel problem but have found no information to solve or test it.  Finally now my bulb has probably failed.  Are parts easily found to repair this projector or am I looking at a projector replacement, since the company is out of business?

You'd need to remove the top from the projector. the light tunnel is between the colorwheel and the lens assembly. remove the metal frame from it. chances are it's falling apart. since the company's out of business, finding a part is an exercise in futility. time to trade up.

Shadow along edge of my SHARP DM-3551 copier's copies


Run a page with the cover or document feeder open. Just a solid black page. If the shadow runs completely edge to edge on the paper, your problem is in the drum unit or less likely the fiser.. If the there is a clean edge delete, then the problem is either dirty scanner mirrors or the laser. It is far less likely in the optical/laser system but still likely. I tend to believe the problem is in the drum unit.

Not showing entire image on screen


It's possible that your projector doesn't natively support your display resolution, but to know more it would be best if you could provide the following details:

Projector Model
PC Model
Windows Version
Windows Resolution/Refresh Rate
Display type (if laptop) cloned/extended, etc

Thanks!

We have an LP600 with a black fizzy edge slowly sliding into the image field from the left picture edge?


sounds like you have a broken light tunnel. Its just a four sided mirror that has a broken side.

I have shadowing on the edges when in wide-screen. When in normal screen the image is fine. How do I get rid of the shadow? Also, is there a way to clean the mirror inside the unit?


the only way to properly and safely clean anything inside is with canned air. as for the shadow, replace the light tunnel. you can get the part from an infocus service center and replace it yourself, or send it in for repair. either way, try av solutions in ny. they're really good. www.avsolutionsny.com

Shadowing on lower right of screen on InFocus LP70+


the light tunnel (like a square tube of mirrors) is collapsing. it needs to be replaced, but it's a bit involved, so and infocus service center would be your best bet. if you wish to try it yourself, let me know.

Infocus image problem


That is caused by a collapsing light pipe.
This is a mirrored glass square component that is located directly behind the color wheel. It is comprised of 4 mirrored section approximately 40mm x 8mm that are glued together with a hi-temp adhesive to form a square. The artifact you see is one of these mirrored glass section's has come unglued and has moved inwards blocking one edge of the image. The edge of this shadow is not shar because this failure is not at a focal point.WHEW..all that being said it's possible to re-glue it if you are electro-mechanically savvy and have steady hands. If you need to take it to a service they will most likely just just replace the complete DLP engine (the whole optic assembly) Hold on to your wallet!!


Cheers

InFocus LP70 Won't display Top 3/4 of screen even with new bulb


if the colorwheel stopped spinning, the projector would shut off. take the lamp out and spin the colorwheel (with a pencil eraser) to the clear section and look at the square on the other side. if it's not a complete square or something is inside the square, your light tunnel is collapsing and needs replacement (also called an integrator rod).

Print margins too large on Xerox DocuColor 12 - How do I reset?


Not sure this is what your needing but ,,

The Edge Erase default setting is No Erase, which enables the copies to print within 2 mm of each page edge. This is normally sufficient to remove shadows from the edges. If the dark edge is closer than 2 mm, you must set Edge Erase at Variable Erase.

The Variable Erase option enables the copier / printer to vary the amount of erasure from 0 to 50 mm in 1 mm increments. The same amount of erasure is applied to both top and bottom edges or right and left edges of the document.

  1. Select [Edge Erase] on the Added Features tab. The Edge Erase screen is displayed.
  2. Select [Variable Erase]. The Variable Erase screen is displayed.
  3. Under Top & Bottom Edges, use the [Up] arrow to increase the amount of erasure at the top and bottom edges. Use the [Down] arrow to decrease the amount of erasure at the top and bottom edges.
  4. Under Left & Right Edges, use the [Up] arrow to increase the amount of erasure at the left and right edges. Use the [Down] arrow to decrease the amount of erasure at the left and right edges.
  5. Under Original Orientation select the page orientation that most closely resembles the orientation of the document on the Document Glass.
  6. Select [Save]. The Edge Erase screen is displayed.
  7. Select [Save]. The Added Features tab is displayed and shows the new Edge Erase values.

Infocus 70+


We have had similar issue w/ multiple LP70+ projectors. The units get to be 1-2 years old and suddenly the right vertical edge of the display is distorted. There is usually a shadowed vertical bar that clouds about 3-5% of the horizontal space from the right edge.
What's the cause?
