Question about Epson Perfection 4990 Flatbed Scanner

1 Answer

Copies of printed material no longer sharp. Can this be adjusted?

I lay a page of print from a book, scan it in the auto mode and the print is not as sharp as it formerly was. It seems to be slightly out of focus. Is there some way to adjust this?

The printer may have adjusted itself to print in grayscale instead of black and white. Check the print settings.

SOURCE: Gray backround

Does your scanner software give the option to choose different modes...grayscale, color, black & white?? This sounds like it's scanning in grayscale....if you can change it to black & white, the background should remain white.

SOURCE: scanning red and green over

Had the same on my Epson Perfection 1650. I was about to throw it out but decided to take a look inside. Unscrewed and took the top off (with glass bed), then unscrewed the area that houses the scanner light and a set of three mirrors, cleaned with a lens brush the mirrors although did not see any more than one spec. Put it all back together and now it works great. not sure what I fixed, but it IS fixed. may have been put together badly in the factory as this problem happened soon after purchase. I may have knock something out of place at some point. Anyway you may be lucky too!

Epson V200 Copy Utility Problem with Incorrect Margin Output

I had the same problem forever and i just sat down today to fix it.
I have a Konica Minolta PagePro 1350w for my printer. The resolution
is set default at 600x1200 when in the Output Paper - Paper setting.
Change the resolution for your printer if you can to 1200x 1200 in the output paper - paper setting in the copy utility software, and
that should solve your problem with this half page copies. It might
still cut off some margins at the very edge, but most of the time they're just
plain paper margin. Hope this helps you out.

I MAKE A COPY AND I GET MY COPY BUT I ALSO GET A BLANK SHEET.


See if your copier has "Book mode" if so it's scanning you original and looking and scanning for an open book, i.e. page left on glass and page Right (two) on glass. Like you had a book flattened out on the glass. Make any since? #2 possible malfunction in print button. #3. Are sheets coming out stuck together or do they appear to be two separate scans?

Copy Output all black


Janson; does this problem only occur if you're doing copying via the auto feeder, or also if you lay the paper in manually? The auto feeder uses a small glass opening to the front (or left) of the main flatbed scan area; if there is an issue with that area letting in light, an all black page would result. If you get all black with either type of scan, but regular printing still works, then you may have a dead scan element. Try scanning something to your computer or to an email account to see if normal scanning still works.

When you select double sided printing in the printing options, there are two choices--book mode or tablet mode. I think you want book mode.

Oh, it's the colors you are having a problem with. Then you probably want to perform an Auto Gradation Adjustment. It's on pages 162-163 of the manual found here: http://download.support.xerox.com/pub/docs/DocuColor_3535/userdocs/any-os/en/3535_User_Guide.pdf

Here is what it says:

Auto Gradation Adjustment
Auto Gradation Adjustment is a color calibration for the copier and printer. An Auto Gradation Adjustment compensates for differences between the actual and the expected toner densities for each color. An Auto Gradation Adjustment should be performed whenever there is a noticeable change in the appearance (quality) of the output, particularly changes in color
tones or densities. Performing an Auto Gradation Adjustment on a regular basis will help to maintain consistent color quality over time.

NOTE: Since an Auto Gradation Adjustment can affect all jobs for all users, it is recommended that this procedure be performed only by the Machine Administrator.

Copy Job - Text Compensates tones when a text original is copied.
Copy Job - Photo Compensates tones when a photo original is copied.
Print Job Compensates tones when printing with controller line screen.
Network Controller - 1 Compensates tones when printing with Network Controller screen type 1.
Network Controller - 2 Compensates tones when printing with Network Controller screen type 2.

NOTE: Printing the chart for Auto Gradation does not increase the meter count.
NOTE: When gradation adjustment is executed, the following
changes will be made to default copy settings set in System Settings mode: Copy density = Normal or Auto, Color Shift = Normal, Saturation = Normal, Color Balance = 0, Sharpness = 0.
NOTE: When Print or Network Controller gradation adjustment is executed, the printer’s output profiles for the available screen types are compensated.

1 On the Image Quality Adjustment screen, select Auto Gradation Adjustment.
2 Load 8.5x11 inch or A4 paper into Tray 5 (Bypass). Move the paper guide to gently touch the edge of the paper.

3 Select the desired gradation adjustment screen:
• Copy Job - Text
• Copy Job - Photo
• Print Job
• Network Controller - 1
• Network Controller - 2
Press Start. The Adjustment Chart is output.
4 Place the Adjustment Chart face down on the Document Glass with both Magenta color patches against the left side of the glass.
5 Place 5 sheets of white paper on top of the Adjustment Chart and close the DADF. Select Start.
6 To continue Auto Gradation Adjustment with other screens, repeat steps 2 to 5. When you are finished, select Close until the System Settings screen is displayed.
7 Select Exit to exit the System Settings mode.
