Ricoh MP 7502 light copy and print quality

Do not suck (vacuum) anywhere near the ID sensor as doing so can generate enough static to damage the sensor. You can vacuum most of the drum frame but stay at least 1 inch away from the sensor. Use an artist's brush to remove toner next to the sensor. Clean the face of the sensor itself with a soft cotton cloth moistened with water only, anything else can damage the sensor.

I always pull both sensors out,the one on the top of the clam shell, and put them to the side..
This way i can vacuum out w/out any issues....

I just had a bad toner hopper that caused light copies.after a developer change.They don't usually break but something to check.

I think it cloggs over time too and a quick vacuum will remedy..also that plastic piece above dev unit with the 2 mylars that fall off too when toner comes back from drum unit....

After ck all the above try to force toner supply and print a test pattern (checkers flag) before and after to see if any change.Plus ck if the toner is oem

I found the problem. I changed transfer belt from other machine and it gave so dark black. I bought a transfer belt from AliExpress.
