[CQ] Kyocera 4551ci Light copies off glass

[Doug James]

Prints from PC and internal prints are fine. Prints off glass very light at a consistent light density (No wave or repetitive marks). I cleaned optics very good and no change. Any ideas would be very helpful THANKS !!

ECO mode on for copying?

No I looked, was wondering about that. Also messed with density settings (Copy only) had no effect. Thanks so much for your response !!

Re: Kyocera 4551ci Light copies off glass

it happens with all original image settings?
the shading plate would cleaned?
faint images from DP also?
does it also happen during scan to pc/ usb or not tested?

--> old system, maybe lamp end of life
--> U411?

PC Print is working fine so in optics I am thinking. I didn't think of checking DP I will do that. I cleaned it fairly well. Not sure if shading plate. I did white strip under glass. I will check lamp also THANKS !!

Re: Kyocera 4551ci Light copies off glass

have had faint copies but fine scan results in past!
This is the reason why i ask for this.
In my case the ISC pwb was broken.....
2 diff picture processing areas in the memory.
(Also usefull for lamp checking)

You haven't mentioned doing any sort of color calibrations. That seems like a logical next step. =^..^=

if he has a broken lamp, he can get print problems after U410 and U411...

Hi Blackcat... I did do a toner curve and calibration. The toner curve prints were perfect and also read fine when read by scanner.

Just in case, backup the machine before you do anything else, just to be safe. You can try running U021, and then see what happens. It will wipe it basically back to factory, and if it doesn't make a difference, you can push the backup on to the machine again. If it does change, then it's something setting related, whether a setting is corrupt, or whatever.

Had a weird issue on a Sharp once that forced toner save mode on out of nowhere. Couldn't figure out why, and the only thing that fixed it was resetting system settings to factory defaults, and then it let me change it. It had been out there for a few years at that point, so it made no sense.

Same type of deal... copier has 120K on it and in good shape
