SCAN GLASS CURE?

[michaelmiagi]

Ive been a copier technician for about 16 years and Im tired of having to walk customers through cleaning their scan glass. Has anyone figured out a trick to keep this from happening? Maybe some sort of cleaner or solution that will keep ink from drying on glass and wont affect copy quality?

I know Sharp has a silicon based oil that with a drop and buffing it out helps with the ink, dirt, whiteout from sticking to the glass.
I suppose any silicon oil would work, as long as it is just a drop.

Sometimes it's about the originals. For example pencil originals for accountants, or whiteout smeared on the slit glass. As far as I'm concerned, the only thing to do for those users is education to clean the glass as often as it gets dirty.

There are some situations the white plate becomes too close to the slit glass. Depending on the model, sometimes you can add a few layers of self adhesive mylar at the front and rear, to increase the spacing between the white plate and slit glass. Typically less than 1/2mm increased spacing.

I'm not sure how much this will help, but I have found that it is useful to show customers how to identify that problem so that they can clean the scan glass. From what I've seen around here, many of them would prefer to do that themselves rather than wait for me to show up.

I seriously doubt anyone does this anymore, but many years ago we used liquid car wax on the copy board glass.

It prevented originals from skewing as the DF belt moved them, and kept "junk" from sticking to it.

We would however, put it in an unmarked container before bringing it into a customer's office, though. I remember getting a few smart@ss responses when using the original container.

Also a good idea to explain that a speck of dirt on the scan glass will result in a horizontal line. it's just as important to explain that if the line goes almost completely across that it's most likely on the glass, if it goes totally edge to edge it's most likely elsewhere.

I still use Rain-X for skewing problems. I thinks its helps with ink sticking, but there is nothing for white out because the new kind never completely dries.

I always ask them if the line stops short of papers edge.

Alcohol wipes work great at cutting what ever the offending substance may be.

Ohhh.... that little glass ?? (after being mentioned 15 times in conversation)

I don't know how much this will help, but I've seen where some doc feeders build up some dust in the area just before the document travels across the doc feeder glass.
The upshot of that is occasionally a chunk of dust is pushed out of that area by a document and causes lines for a while until another document pushes it off the doc feeder glass.
That happens enough that I give the doc feeder a good blast of air from a can anytime I see that problem anymore.

I have been known to polish the glass with fuser oil. Not a perfect solution but it helps alot.
