Ricoh 3800 printing dots on the page

You have to measure the distance between dots, to see where is the problem. Probably there is a problem with black drum unit, or teflon plate in fusing section. Call for service please

Replace the drum unit

What are the correct colour settings for optimum colour printing for Ricoh Aficio Cl7200

Sounds like the cyan photoconductor unit needs to be replaced. Usually what ever the color dot is that photoconductor has a pinhole in it and the only to get rid of it is to replace it.

The black dots could be a few things, the most likely would have something to do with the drum area because the dots didn't appear until after service. If the dots are only about an inch apart it is probably the charge roller. If there is only 1-2 dots per page, the issue is likely with the drum. These figures are assuming you are running 8 1/2 x 11 paper with the long edge being fed in first. If this is the case, you can change the paper to feed with the short edge first and this may get you by until the technician gets back out to fix it.

How many pages have you printed? I you printed more than 2k, start considering new fuser. Read your manual for cleaning procedures. If not resolved, then.

If the marks are along the same line and look like dots the black photoconductor needs to be repalced.

Almost certainly the black PCU...order from dealer

MP 1600L copier/printer produces print-outs with small toner dots spread over the paper. How can I solve this problem?

Notice what color the dots are. Most of the time you need to replace that color photoconductor.
