    Ricoh MP3353

    Customer is using copier mainly for printing yet has been noticing when copying copies are lighter than prints. Initially I cleaned copier to no avail adjusted SP2201 with not much difference. I replaced the drum and drum blade didn't change much. There was an adjustment on the Ricoh Aficio 1022 I believe SP5106 that helped in making copies darker yet it's not in this copier. Looking for help in this; to darken copies.
    Had customer print out sample which came out good yet when copy was made some solid areas were somewhat washed out. From what I saw I would think if it were the drum and or unit it would do so in print jobs as well.
    Thanks!!!

    There are countless threads about the issue of good copies and light prints as the PCU approaches end of life on machines from way bask to AF1022/27 thru the xx53 series
    SP2907-001 thru 005 is the SP mode that you're looking for, that will improve the copy quality as the PCU gets close to end of life. The default is 5. Setting them to 7 or 8 usually does the trick for me.

    Question: When the copy quality faded, why would you only replace the drum, and not the Dev? It takes 5 minutes more, and Dev has been the primary causes of light copies since the beginning of time

    Customer didn't want to spend the money(most my customers have tight pockets) and after replacing drum and finally getting to see samples I felt PCU would not have solved issue. One thing I've found in my 36 years developer only goes bad if not used or gets bad toner put in it. Most my copiers are using the original developer in copier and copies are fine. To be honest with this copier the copies are fine to me could use a little contrast.
    Thanks for your help!!!

    Normally when copying starts to get light but printing does not it means that there is dust, toner or some other filming on the mirrors and even the under side of the platen glass. This will cause it to see a darker color when doing white reference during initialization. As a result the entire gray scale gets shifted.

    Turn the power off. Remove and clean both sides of the platen glass and the bottom of the scale which is where the white reference is. Also clean all three mirrors. Be careful with the mirrors as they are super to scratch. Also clean the lamp reflector.

    Reassemble and turn power back on. 9 times out of 10 the light copies will be gone.

    I was assuming that he would have done that, but after finding out that he feels that developer almost never goes bad, I should have assumed nothing

    I had a instant where there was dust under the scale only.

    all this was performed before deciding to replace the drum. Had I been shown the samples on my first trip I would not have replaced the drum.
    Thanks!!!

    This is very common on this model group. The developer needs to be replaced.

    There is the fact that there is a difference in the laser intensity between printing and copying. Higher laser intensity during printing makes for darker blacks.
